What are some important safety practices for operating the machine?

Safety is dependent upon the awareness, concern and prudence of those who operate or service the equipment. It is the operator’s responsibility to read the manual and all publications associated with the equipment. The operator should learn the proper use of the machine, the location and purpose of all the controls, and be aware of the dangers. Never allow anyone to operate or service the machine without proper training and instruction. Wear all necessary protective clothing and personal safety devices. Inspect the area where the equipment will be used. Never operate equipment that is not in perfect working order. Never disconnect or bypass any switch. Keep the equipment clean. Always use the seat belt when operating tractors equipped with a ROPS. Fuel is highly flammable, handle with care. The operator should keep hands, feet, and clothing away from moving parts. The operator should keep the area of operation clear of all bystanders. Never carry passengers. Never operate mowing equipment without the discharge deflector securely fastened in place. Hydraulic fluid under pressure can penetrate the skin and cause serious injury. Operate the machine up and down the face of slopes (vertically), not across the face (horizontally). Keep vehicle in gear when descending slopes. To prevent tipping or loss of control, do not start or stop suddenly; reduce speed when making sharp turns. Use caution when changing direction on slopes. Never use a seat belt when operating a tractor without a ROPS.

---

What does the operator backup system do?

The operator backup system prevents the engine from starting unless the parking brake is engaged, the PTO is disengaged, and the transmission is in neutral. The system also stops the engine if the operator leaves the seat with the PTO engaged, the transmission in gear, or the parking brake disengaged.

---

What should be done daily before operating the machine?

A daily inspection should be performed only when the engine is off and all fluids are cold. Lower implements to the ground, engage parking brake, stop engine and remove the ignition key. Perform a visual inspection of the entire unit, look for signs of wear, loose hardware, missing or damaged components. Check for fluid or oil leaks. Check the fuel supply, radiator coolant level, crankcase oil and hydraulic oil. All fluids must be at the full level mark. Make sure the implement is properly assembled to tractor and is properly adjusted. Make sure the machine is lubricated and the tires are properly inflated. Test the operator back-up system.

---

How do you test the operator back-up system?

Perform each of the following tests to insure the operator back-up system functions properly. Stop the test and have the system inspected and repaired if: the engine does not start in test 1, or; the engine does start during tests 2, 3 or 4; the engine continues to run during tests 5, 6 or 7. Refer to the chart for each test and follow the check (✓) marks across the chart. Test 1: Represents normal starting procedure. The operator is seated, parking brake is engaged, the transmission is in neutral and the PTO is disengaged. Test 2: The engine must not start if the PTO is engaged. Test 3: The engine must not start if the parking brake is disengaged. Test 4: The engine must not start if the transmission is not in “neutral”. Test 5: Start the engine, engage PTO then lift your weight off the seat. Test 6: Start the engine, disengage parking brake, lift your weight off the seat. Test 7: Start the engine, shift transmission to “low” (be sure parking brake is engaged) lift your weight off the seat.

---

What is the start-up procedure for the machine?

Sit in operator’s seat, make sure PTO is disengaged, parking brake is locked and transmission lever is in neutral position. Fasten seat belt when operating tractors equipped with a ROPS. Move throttle lever to 1/3 throttle and turn ignition switch to “ON” position. (Diesel Engine Only) Depress glow plug switch for about five (5) seconds then release the switch. The colder the temperature, the longer it will take to energize the plugs. This step is not necessary when starting a warm engine. (Gasoline Engine Only) Pull choke knob upwards to close the choke plate. Refer to the engine manual for additional starting instructions. Turn ignition key to “Start” position and release as soon as engine starts. Do not hold key in “Start” position for more than 10 seconds at a time. Allow the engine to become warm and properly lubricated before operating at high R.P.M.

---

What is the procedure for driving/transporting the machine?

If the tractor is driven on public roads, it must comply with state and local ordinances. Contact local authorities for regulations and equipment requirements. When operating tractor without implements travel at reduced speeds when making turns to prevent tipping or loss of control. Disengage PTO and raise implement to the transport position. Disengage parking brake, place transmission lever in “high” or “low” range. (Select 2 or 4 wheel drive on 4-WD models). Once the 4-WD switch is activated, the Turfcat will shift from 2-WD to 4-WD when the traction pedal is released. The system will then return to 4-WD when traction pedal is depressed. When changing from 4-WD to 2-WD, decelerate to approximately 5 MPH (8 kph) before activating the 2-WD/4-WD switch. Move throttle to “fast” position and slowly depress top of traction pedal or move forward or bottom of traction pedal to move in reverse. Always come to a complete stop before shifting from forward to reverse or when applying the differential lock.

---

What is the procedure for parking or stopping the machine?

If any park/stop area is not on a level surface, follow the guidelines outlined by the grounds superintendent. If the tractor is parked on an incline, chock or block the wheels. To park the tractor under normal conditions, disengage PTO then raise and lock the implements in the transport position and move away from the area of operation. Select a flat and level area to park. Release traction pedal and bring the tractor to a complete stop. Engage parking brake and lock. Disengage all drives, lower implements to the ground, reduce throttle to 1/4 or 1/3 and allow engine to operate at no load for 2 to 3 minutes. Engage parking brake, stop the engine and always remove ignition key.

---

How should you mow with the machine?

Mow with the uncut grass to the left of the mower (side discharge mowers only) so that grass clippings will be discharged evenly. Discharging clippings over uncut grass creates a buildup of wet clippings that may prevent uniform cutting and impose an unnecessary load on the tractor and mower. Plan the mowing pattern so you can mow straight forward as much as possible. Reversing and changing mowing direction each time you mow will help to eliminate matting, graining, and corrugation, thereby enhancing the appearance of the grass. The correct operating speed will depend on the height, density and type of grass to be cut as well as the type of terrain. For extremely tall grass, first cut at a higher setting and then at the desired height. Always mow with the throttle lever in “fast” position. Vary ground speed with the traction pedal. Slow down when turning, operating in tight areas, mowing on hillsides or over rough terrain and when trimming with left side of mower. Lower implement to the ground. Make sure lifting cylinder is fully retracted.

---

What should you be aware of when operating the machine on hillsides?

To minimize the possibility of overturning, the safest method of operating on hills and terraces is to travel up and down the face of the slope (vertically) not across the face (horizontally). Avoid unnecessary turns, travel at reduced speeds, and stay alert for hidden hazards. Do not operate this tractor on slopes greater than 12.5 degrees without first installing a R.O.P.S. Never use this tractor on slopes greater than 18.8 degrees. The tractor has been designed for good traction and stability under normal mowing conditions, however, use caution when operating on slopes, especially when the grass is wet. Always mow with engine at full throttle. Use the traction pedal to reduce forward speed to maintain the proper engine frequency. To prevent tipping or the loss of control do not start or stop suddenly or make sharp turns. Lower implement to the ground when descending slopes. Climb at an angle to the hill with the left wheel higher than the right wheel. If the left wheel begins to spin, apply traction assist. If the tractor tends to slide or the tires begin to “mark” the turf, angle tractor into a less steep grade until traction is regained or tire marking stops. If tractor continues to slide or mark the turf, the grade is too steep for safe operation. Do not make another attempt to climb. Disengage PTO and back down slowly.

---

How do you use wheel weights to improve traction?

To improve traction and steering control, wheel weights can be added to the wheels. The extra weight should only be added after careful consideration of the mowing conditions. Extra weight may limit the tractor’s ability to climb slopes. Wheel weights should be used in pairs. Operation with weight on one side only will cause uneven tire wear and will cant or tip the tractor. Liquid fill can also be used in the rear tire as an alternate or in addition to the weight. If the anticipated temperatures are below freezing, use a calcium chloride solution.

---

What should be done before making adjustments or repairs?

Before making any adjustments or performing maintenance, the entire adjustment or maintenance section should be read.

---

What are the steps to take before adjusting, cleaning, or repairing the machine?

---

How do you adjust the hydro neutral?

If the tractor “creeps” in either direction when the engine is running but the traction pedal is not depressed, adjust spring tension so that the pedal always returns to neutral when released. The tractor may “creep” when the transmission oil is cold. Operate the tractor for 15 minutes before determining if adjustment is required. Use extreme caution when making this adjustment as the wheels will be off the ground and the engine will be running. Tilt the seat forward and place a small amount of lubricating oil on all the pedal linkage pivot points.

---

How do you adjust the ball joints?

Whenever adjusting ball joints, the cut-out in the ball joint must be parallel to the mounting bracket (within 1/4 in., (6 mm) per foot), then secure in place.

---

How do you adjust the wheel creep?

Hoist the tractor so all four tires are off the ground. Place blocks under the frame to prevent accidental lowering of the tractor during adjustments. Disengage parking brake and place the 4-WD/2-WD switch in 2-WD position (4-WD Tractors only). Start engine and move throttle lever to full speed. Check rotation of drive tires and then make the adjustment with the engine running. (2-WD) – Tractor(s) – Adjust nut (J) 1/2 turn counterclockwise for forward creep or 1/2 turn clockwise for backward creep. (4-WD Tractors) – To find the neutral point of the hydro, loosen nut (F) and adjust rod (G) by turning nut (H) inwards to adjust for forward creep or outwards to adjust for backward creep. When the drive tires stop turning, the hydro is in neutral. Hold nut (H) in place and tighten nut (F) against the yoke. Stop the engine.

---

How do you adjust the traction pedal stop?

Forward: Move the pedal to its maximum forward position. Adjust stop bolt (L) until the bolt head touches the pedal. Then turn the bolt one revolution counterclockwise (out against pedal) and tighten nut (M). Reverse: Pedal travel can be adjusted with rod (K). After adjusting the rod, stop bolt (L) must be readjusted. Excessive travel speed in reverse may cause steering tires to “lock”.

---

How do you adjust the reverse sensing switch?

If the switch is not properly adjusted, the 4-WD function may be delayed or prematurely engaged. Loosen screws (N) and adjust switch so that wiper (P) is activated by arm ® as soon as pedal is depressed in the forward direction. Tighten hardware (N).

---

How do you adjust the interlock switch for the brake?

---

How do you adjust the interlock switches for the 4-WD models?

Switch (X) is to insure braking on the rear axle when shifting through neutral on an uphill grade. Position shift lever in neutral. Loosen screws (Y) and adjust switch (X) so that actuating arm of shift lever opens the contacts of switch (X). Tighten hardware.

---

How do you adjust the interlock switch for neutral?

Switch (V) is to insure the tractor will start only if the transmission in neutral (all models). Switch (Z) must be adjusted so the PTO will not work when the shift lever is in high range. Position shift lever in neutral. (4-WD tractors) Loosen nuts (U) and adjust bolt (W) so that the head of the bolt closes the contacts of switch (V). (2-WD tractors) Loosen nut (U) and adjust bracket (W) so that pivot rod engages ball on switch (V) when lever is in neutral, and switch (Z) when lever is in high range. Tighten all hardware.

---

How do you adjust the steering stop?

The bolts are adjusted to prevent the steering cylinder rod from becoming completely extended or retracted during normal operation. Loosen nut © and turn bolts (B) completely in against mounting block. Turn steering wheel to left so steering cylinder rod (A) is completely retracted then turn the steering wheel to the right to extend the rod 1/16 to 1/8 in., (2 to 3 mm). Adjust bolt (B) until it touches steering stop block (E). Tighten nut © against mounting block to lock the bolt in place. Turn steering wheel to right so steering cylinder rod (A) completely extended then turn the steering wheel to the left to retract the cylinder 1/16 to 1/8 in., (2 to 3 mm).

What is the procedure for servicing the battery?

Make absolutely certain the ignition switch is “Off” and the key has been removed before servicing the battery. When installing a battery always assemble the red, positive (+), battery cable first and the black ground, negative (-), cable last. When removing the battery, always remove the ground, negative (-), cable first, and the red, positive (+), cable last. Check the electrolyte level. Clean the cable ends and battery posts with steel wool. Use a solution of baking soda and water to clean the battery. Do not allow the solution to enter into the battery cells. Tighten cables securely to battery terminals and apply a light coat of silicone dielectric grease to terminals and cable ends to prevent corrosion. Keep terminal covers in place. Make certain the battery is securely fastened to battery tray.

---

What should be done before charging the battery?

Whenever possible, remove the battery from the tractor before charging and make sure the electrolyte covers the plates in all the cells. Make sure the charger is “Off”, then connect the charger to the battery terminals as specified in the charger’s Manual. Always turn the charger “Off” before removing a charger lead from the battery.

---

How do you take care of the machine?

Wash the tractor and implements after each use. Keep the equipment clean. Do not wash any portion of the equipment while it is hot. Do not use high pressure spray or steam. Use cold water and automotive cleaners. Use compressed air to clean the engine and radiator fins. A special Blow Gun is available from your Jacobsen distributor. Do not spray water directly at the instrument panel, electrical components or at bearing housings and seals. Clean all plastic or rubber trim with a mild soap solution or use commercially available vinyl/rubber cleaners. Repair damaged metal surfaces and use Jacobsen “Orange” touch-up paint. (Section 1.6). Wax the tractor for maximum paint protection.

---

What should be done before servicing the fuel system?

Before servicing any filter, thoroughly clean the filter housing and the area around the filter. Dirt must not be allowed to enter into the fuel system.

---

How do you service the fuel filters?

Disconnect the hoses from the primary filter. Remove and discard the filter. Assemble new filter with the arrow pointing away from tank. Tighten hose clamps. Remove and discard secondary diesel filter. Apply a light coat of oil to the gasket and hand tighten. Fill fuel tank and bleed the fuel system.

---

How do you bleed the fuel system?

Bleed the fuel system after the fuel filter and lines have been removed, or after the fuel tank has become empty. Fill the fuel tank to within 1 in., (25 mm) below the filler neck. Open air vent plug (A) on top of the fuel filter then turn the ignition to “on” and allow the fuel pump to fill the filter and purge the air from the system. Close the air vent plug when fuel begins to flow out. Always keep the air vent plug closed except when air is vented.

---

How do you inspect the hydraulic hoses?

Always lower implements to the ground, disengage all drives, engage parking brake, stop engine and remove key before inspecting or disconnecting hydraulic lines or hoses. Inspect hoses and tubes daily. Look for wet hoses or oil spots and replace worn or damaged hoses and tubes before operating the machine. The replacement tube or hose must be routed in the same path as the existing hose, do not move clamps, brackets and ties to a new location. The hydraulic system can be permanently damaged if the oil becomes contaminated. Before disconnecting any hydraulic component, clean the area around the fittings and the hose ends to keep impurities out of the system. Before disconnecting any hydraulic component, tag or mark the location of each hose then clean the area around the fittings. As you disconnect the component, be prepared to assemble plugs or caps to the hose ends and open ports to keep impurities out of the hydraulic system and also prevent oil spills. Make sure “O” rings are clean and hose fittings are properly seated before tightening. Keep the hose from twisting. Twisted hoses can cause couplers to loosen as the hose flexes during operation resulting in oil leaks. Kinked or twisted hoses can restrict the oil flow causing the system to malfunction and the oil to overheat and also lead to hose failure.

---

How do you check the hydraulic oil?

Park the tractor on a flat and level surface, fully lower implement to the ground and stop the engine. Thoroughly clean the area around the oil cap to prevent dirt or grass from entering and contaminating the system. Oil temperature should be at 60°F to 90°F (16°-32°C). Do not check oil level when oil is hot. Hydraulic oil level should never be below the low level mark or more than 1/4 in., (6 mm) above the full level mark. Change oil after a major component failure, or if you notice the presence of water, foam, or a rancid odor (indicating excessive heat). Remove drain plug from bottom of tank and remove filler/vent cap. Check and clean the breather cap. Replace if necessary. Drain transaxle on 2WD tractor. Reinstall drain plugs and fill hydraulic tank and transaxle (Section 5.19) to full level on dipstick. Use Jacobsen hydraulic oil. Jack up front tires so they spin freely then start engine, place transaxle in neutral. Operate hydraulic system and cycle lift cylinders for a minimum of three minutes. Recheck oil level on dipstick and add oil if necessary.

---

How do you service the hydraulic oil filters?

Refer to Section 7.1 for specific maintenance intervals. Remove old filter(s) and fill new filter with clean oil. Install new filter(s). Hand tighten only. Operate engine at idle speed with hydrostatic pump in neutral for five minutes. Check hydraulic oil level on dipstick and add if necessary.

---

What is the procedure for using jumper cables?

First check the condition of the “discharged” battery. Stop engine on vehicle with good battery. Connect RED jumper cable to the positive (+) terminal on the good battery and to the positive (+) terminal on “discharged” battery. Connect BLACK jumper cable from the negative (-) terminal on the good battery to the frame of tractor with discharged battery.

---

How do you properly maintain the ROPS?

The seat belt, mounting hardware and any accessories within the R.O.P.S. should be carefully inspected and all damaged parts replaced immediately. Once the ROPS has been subjected to any form of impact it should be replaced. Use only Jacobsen replacement components as specified in the Parts Catalog. Do not loosen or remove bolts; do not weld, drill, modify, bend or straighten a damaged structure. Check and retorque all hardware regularly.

---

How should you maintain the tires?

Keep tires properly inflated to prolong tire life. Pressure should be checked while the tires are cool. Check the pressure and inspect tread wear. Turn the wheel so that valve stem is at the top before checking inflation pressure of liquid filled tires. Use an accurate, low pressure tire gauge. Front: 10 psi (70 – 83 kpa). Rear: 8 – 10 psi (55 – 70 kpa). Unless you have the proper training, tools and experience, DO NOT attempt to mount a tire on a rim. Improper mounting can produce an explosion which may result in serious injury.

---

What are the procedures for mounting wheels?

Make sure the tractor is parked on a solid and level surface. Never work on a tractor that is supported only by the jack. Always use jack stands. Engage parking brake before lifting the tractor to install wheels. If only the front or rear of the tractor is raised, place chocks in front of and behind the wheels that are not raised. Remove dirt, grease and oil from stud threads. Do not lubricate threads. Position each wheel on hub and inspect to insure full contact between the mounting surfaces of wheel and hub or brake drum. Finger tighten top nut, then rotate wheel so that the opposite nut is at the top and finger tighten. Finger tighten remaining nuts in a (criss-cross) order; always tighten nuts in top position. Check and retorque daily until torque is maintained.

---

How do you check the transaxle oil level on 2WD models?

Park the tractor on a level surface. The lubricant must be maintained just up to the edge of the opening. Remove vent cap (B). Add oil slowly until the lubricant begins to flow out from port (A).

---

How do you drain and refill the transaxle?

Lubricant should be drained when it is warm and flows freely. Remove magnetic drain © and plugs (A and B). Clean and reinstall drain plug © then fill slowly through port (B) until oil begins to flow out from port (A). (Section 7.2-VI).

---

What should you do to prepare the machine for storage?

Lubricate all fittings and friction points. Replace the hydraulic oil and oil filters. Wash the tractor thoroughly. Repair and paint damaged or exposed metal. Inspect the tractor, tighten all hardware, replace worn or damaged components. Clean the tires thoroughly and store the tractor so that the load is off the tires. If the tractor is not on kickstands, check the tires at regular intervals and reinflate as necessary. Keep the machine and all its accessories clean, dry and protected from the elements during storage. Never store equipment with fuel in the tank where fumes may reach an open flame or spark and ignite the fuel or fuel vapors.

---

How do you store the battery?

Remove, clean and store the battery in upright position, in a cool, dry place. Storage above 80°F (26.7°C) greatly increases self-discharge. If wet batteries are discharged, the electrolyte will freeze when stored below 20°F (-7°C). Check and recharge battery every 60 to 90 days while in storage.

---

What should be done when storing the diesel engine?

While the engine is warm, remove drain plug, drain the oil from the crankcase and change oil filter. Install drain plug and refill with fresh oil. Clean exterior of engine. Paint the exposed metal or apply a light coat of rust preventative oil. To prevent the build up of gum residues and varnish films, Jacobsen recommends filling the tank with stabilized fuel. Use an anti-oxidant fuel conditioner, such as STA-BIL. Read and follow the instructions on the container.

---

What should you do after taking the machine out of storage?

Check and reinstall the battery. Check or service the fuel filters. Check the radiator coolant level. Check oil level in the engine crankcase and hydraulic system. Fill the fuel tank with fresh fuel. Bleed the fuel system. Make certain that the tires are properly inflated. Start the engine and operate at 1/2 throttle. Allow enough time for the engine to become properly warmed and lubricated.

---

How should you lubricate the machine?

Always clean the grease fitting before and after lubricating. Apply grease with a manual grease gun and fill slowly. Do not use compressed air guns. Lubricate with grease that meets or exceeds NLGI Grade LB specifications. For smooth operation of pivot points and other friction points, apply several drops of SAE 30 wt., oil as required. Remove wheels and repack the bearings once a year. Coat motor shaft splines with Molybdenum Disulfide E.P., lithium grease.
