CUB CADET 2130 (01) PDF Document

To ensure your safety when using the CUB CADET 2130, always follow these instructions:

General Safety:

• To prevent accidental starting, always pull the high tension wire(s) off the spark plug(s) before servicing or adjusting the machine.

• Do not allow children or bystanders near the machine while it is being adjusted or serviced.

• Do not wear jewelry or loose clothing. Wear sturdy, rough-soled work shoes. Never adjust or service a machine in bare feet, sandals, or sneakers.

• Always wear safety glasses when using a hammer, chisel, or other tools that may cause chips to fly.

• Reinstall all safety devices, guards, or shields after adjusting or servicing the machine.

Equipment and Environment:

• When operating a power washer, be careful at all times to avoid injury. Maintain proper footing and balance. Never direct the spray at people or animals.

• If using a portable heater, do not use it in the presence of volatile materials like gasoline. When in operation, locate the heater away from the immediate work area to avoid accidental contact. Portable heaters consume oxygen; use only in a well-ventilated area. Keep the heater at least four feet from all combustible materials and never use gasoline as fuel.

• Gasoline is highly flammable. Use an approved gasoline container. Never remove the fuel tank cap or fill the fuel tank when the engine is running, is hot, or is indoors. DO NOT SMOKE when working around flammable fuel. Avoid fires by ensuring the container or funnel does not touch the battery. Wipe up spilled gasoline immediately.

• Never use trouble lights or electric powered tools that have cut or damaged cords or plugs. Ensure all electric tools are properly grounded.

• Never run an engine in a confined area, such as a garage or storage building, any longer than is necessary for immediate moving of the machine. EXHAUST GASES ARE TOXIC. OPENING DOORS AND WINDOWS MAY NOT PROVIDE ADEQUATE VENTILATION.

• Electrical storage batteries give off highly flammable hydrogen gas when charging and continue to do so for some time after receiving a steady charge. To avoid an electrical spark or open flame near the battery, always disconnect the battery cables (negative cable first) before working on the electrical system.

Mechanical Safety:

• After servicing, be sure all tools, spare parts, and/or servicing equipment are removed from the machine.

• Hydraulic fluid escaping under pressure can have enough force to penetrate the skin. If injured by escaping fluid, see a doctor at once. Do not attempt to repair or tighten hoses that are under pressure or with the tractor engine running. Cycle all hydraulic control valves to relieve all pressure before disconnecting lines or performing other work on the hydraulic system.

• When using a welder or acetylene torch, always wear welding goggles and gloves. Keep a charged fire extinguisher within reach.

• Always use safety stands in conjunction with hydraulic jacks or hoists. Do not rely on the jack or hoist to carry the load if it could fall.

• Use pullers to remove bearings, bushings, gears, sleeves, etc. Use hammers, punches, and chisels only when absolutely necessary.

• Be careful when using compressed air to dry parts. Use approved air fixtures, do not exceed 30 psi, wear safety glasses or goggles, and use proper shielding.

The CUB CADET 2130 tractor is shipped with a dry battery. Electrolyte must be added and the battery activated. Follow these procedures for proper battery activation:

1. Remove the battery from the tractor and place on a work bench or table.

2. Fill each cell to the top of the plates with electrolyte.

3. Allow the battery to sit 30 minutes. This will allow the chemical action to take place between the electrolyte and battery plates. Note: When the battery is charged, the heat will cause expansion of the electrolyte.

4. Re-check the electrolyte level and, if necessary, add electrolyte to completely cover the plates.

5. Connect the charger to the battery per instructions with the charger.

6. Charge the battery at 4 AMPS maximum until the specific gravity of each cell is 1.250 or higher. Charging the battery at more than the recommended 4 AMPS will shorten the service life of the battery, and may cause the plates to warp and short out the battery.

7. Check the level of electrolyte in all cells and add, if necessary, to bring level up to split ring.

8. Wash off any spilled electrolyte.

9. Install the battery in the tractor and connect the POSITIVE battery cable to the positive terminal of the battery.

10. Connect the NEGATIVE battery cable to the negative terminal of the battery.

Important Warnings:

• Battery cables must be disconnected in the proper order to avoid arcing. When disconnecting cables from the battery, ALWAYS remove the negative cable first, and then remove the positive cable.

• Electrolyte is diluted sulfuric acid. Use extreme care to avoid spilling and to avoid contact with skin and eyes. Acid can destroy clothing and burn your skin. Should acid come in contact with your skin, flush the area immediately with clean cold water. If acid spills on clothing, first dilute with clean water, then neutralize with a solution of baking soda and water.

• Battery cables must be installed in the proper order to avoid arcing. When connecting cables to the battery, ALWAYS connect the positive cable first, then connect the negative cable.

The turning radius should be approximately equal in each direction, and the front wheels should have a toe-in of approximately 1/8 inch. Check and adjust as follows:

1. Turn the steering wheel fully to the left and note the distance between the front pivot axle and the steering stop on the left steering knuckle.

2. Turn the steering wheel fully to the right and compare the distance between the axle and the right steering knuckle stop with the left knuckle observed in the previous step. The clearances should be approximately equal.

3. If the steering knuckle clearances differ significantly, check the lower steering arm for proper positioning.

4. If the lower steering arm is correctly installed, re-adjust the tie rods and set the 1/8 inch toe-in as follows:

a. Remove the hex lock nuts from the steering arms, and disconnect the tie rod assemblies from the arms.

b. Manually place each front wheel in the straight ahead position (as close as visually possible).

c. Place a mark at the same spot on both front wheels; for example, the mold seam in the center of the tire tread or the inner bead flange of the wheel rim.

d. Rotate the wheels to position the marks at the front horizontal diameter of the wheels, then measure the distance between the marks.

e. Rotate the marks to the rear horizontal diameter and measure the distance between the marks. The distance between the marks at the front should be 1/8 inch less than the distance measured at the rear.

f. If the difference between the measurements is more or less than 1/8 inch, move each wheel equally, in the direction necessary, to achieve the required toe-in dimension.

g. Loosen the hex jam nuts on the tie rod ball joints, if necessary.

h. Turn the ball joint in or out on each tie rod, as necessary to align with the hole in each steering arm.

i. Reinstall the ball joints in the steering arms, but do not tighten the jam nuts against the ball joints now.

j. Remove the dowel pin from the segment gear, and repeat steps 1 and 2 above to ensure the steering knuckle clearances are approximately equal.

k. If the steering knuckle clearances are not approximately equal, determine the difference between the two measurements by subtracting the smaller from the larger.

l. Disconnect the tie rod assembly from the steering knuckle having the least clearance. Turning the ball joint (and tie rod if necessary) in full turn increments, shorten the assembly by an amount equal to half (or closest to half) the difference. Reinstall the tie rod assembly in the steering arm.

m. Disconnect the other tie rod assembly and lengthen by the number of full turns required in the previous step. Reinstall the tie rod assembly in the steering arm.

n. Tighten the hex jam nuts against the ball joints.

5. The turning radius and toe-in should now be correctly adjusted. Recheck and, if necessary, re-adjust per the previous instructions.

Due to normal wear, the tractor brake system should be periodically tested for proper operation and adjusted as follows:

1. Place the tractor on a firm and level surface and stop the engine.

2. For the CUB CADET 2130, move the speed control lever to the fully rearward (neutral) position.

3. This step applies to hydrostatic models, not the 2130.

4. Depress the brake pedal and engage the park brake lever. While observing the rear wheels, push the tractor forward or rearward. If the tractor can be pushed AND the wheels rotate, the brake tension must be increased.

5. Depress the brake pedal to disengage the park brake lever, then release the brake. While observing the rear wheels, push the tractor forward or rearward. If the wheels do not rotate, the brake tension must be decreased.

6. Release the brake pedal and adjust the brake tension as follows:

a. Working from underneath the tractor, remove the internal cotter pin from the adjustment ferrule and disconnect the brake rod assembly from the brake cam.

b. Lightly pull the brake rod forward to ensure the rod is fully seated in the spring and that the spring hook is at the front of the hole in the brake arm. DO NOT actuate the brake cam when pulling the rod.

c. Turning one full turn at a time, turn the adjustment ferrule inward or outward on the brake rod to align the ferrule with the hole in the brake cam.

d. Turn the ferrule outward one full turn and install the ferrule in the brake cam.

e. Depress and release the brake pedal, then check to ensure the spring is not tensioned. There should be a small amount of slack in the brake rod and spring.

f. Manually depress the brake pedal and observe that the spring begins to extend during the initial movement (approximately 1 inch) of the pedal.

g. Repeat steps 4 and 5 above to again test the brakes.

If you are able to rotate the wheels with the park brake engaged, check for oil on brake shoes or drum, excessively worn brake shoes, or possible internal transaxle damage. If unable to push the tractor with the brake disengaged, check for possible brake assembly and/or internal transaxle damage.

The correct installation and adjustment of the clutch adjustment rod is essential to proper operation of the transmission. The adjustment rod must be installed in the FRONT slotted hole of the clutch cam, and the pivot sleeve must be installed in the UPPER hole of the control arm.

Verify the correct installation of the clutch rod and adjust as follows:

1. Depress the brake pedal and engage the park brake.

2. Working from underneath the left frame channel of the tractor, remove the internal cotter pin, securing the pivot sleeve to the control arm. Disconnect the clutch adjustment rod from the control arm.

3. Ensure the adjustment ferrule is at the back of the proper slotted hole of the clutch cam. The extension spring should hold the ferrule against the back of the hole.

4. Without moving the clutch cam or control arm, check the pivot sleeve pin for direct alignment with the upper hole. If not aligned, proceed as follows:

a. Loosen the hex jam nut from the front of the adjustment ferrule.

b. Turn the rod into, or out of, the adjustment ferrule as necessary to align the pivot sleeve with the hole in the control arm.

5. Install the pivot sleeve in the proper hole of the control arm and secure with the internal cotter pin.

6. Tighten the hex jam nut against the adjustment ferrule.

Correct neutral adjustment of the clutch assembly is essential to the proper operation of the clutch. While on a level surface, if the tractor attempts to drive (creep) forward or rearward when neither the forward nor reverse pedal is depressed, neutral adjustment should be checked and readjusted.

1. Drive the tractor for approximately 5-10 minutes to warm up the clutch assembly, then stop the engine and engage the parking brake.

2. Place the tractor on a firm and level surface and chock the front wheels before raising the rear wheels from the ground. Use jack stands to support the rear of the tractor so that the rear tires are at least one inch above the surface, and set on jack stands. Make certain the jack stands are positioned to balance the tractor and prevent tipping.

3. Start and run the engine at approximately 1/2 speed (1800-2200 RPM).

4. Move the speed control lever to one of the mid (third or fourth gear) speed settings, and observe both rear wheels for rotation in either direction.

5. If wheel rotation is observed, adjust the neutral setting as follows:

a. Disconnect the clutch adjustment rod from the control arm by removing the internal cotter pin from the pivot sleeve.

b. If wheel rotation stops when the rod is disconnected, check and readjust the rod per paragraph 6-9. Also check the pedal linkage for binding.

c. If wheel rotation continues, loosen the hex top lock nut and hex cap screw securing the centering spacer to the neutral bracket.

d. If the rotation is in the forward direction, slide the spacer slightly rearward until the rotation stops. If rotating in the reverse direction, slide the spacer forward until rotation stops.

e. Carefully tighten the hex cap screw and top lock nut, making certain the spacer does not move.

f. Stop the engine and engage the parking brake.

g. Check and, if necessary, readjust the clutch adjustment rod per paragraph 6-9.

h. Check and, if necessary, readjust the interlock rod per paragraph 6-11.

6. The inability to attain a neutral setting by adjusting the centering spacer could indicate internal problems with the clutch assembly. Refer to paragraph 5-24 for clutch inspection procedures.

Throttle Cable Adjustment

If the engine does not achieve its high (no load) speed when the throttle control is moved to the full throttle position, check the cable adjustment before performing any other engine or carburetor inspections.

1. Raise the hood and locate the throttle cable connection at the engine.

2. While observing the direction of movement of the engine’s throttle arm, move the tractor’s throttle control lever to the full throttle position.

3. Loosen the screw securing the cable clamp.

4. Push and hold the engine throttle arm fully in the direction of movement noted in step 2 above.

5. While continuing to hold the throttle arm, pull the throttle cable conduit back through the clamp (away from the arm) to remove any slack in the cable and tighten the screw securing the clamp.

6. Start the engine. Use a tachometer to check the high and low speed engine rpm to specifications. Refer to the appropriate Engine Service Manual if adjustment is necessary.

Choke Cable Adjustment

If the engine is difficult to start or runs roughly when warmed up, check the choke cable setting before performing any other engine or carburetor inspections.

1. Raise the hood and locate the choke cable connection at the engine.

2. While observing the direction of movement of the engine choke arm, pull the tractor’s choke handle out.

3. Loosen the screw securing the cable clamp.

4. Push and hold the engine choke arm fully in the direction of movement noted in step 2 above. If desired, the air cleaner cover and element may be removed to ensure that the carburetor choke plate is closed completely.

5. While continuing to hold the choke arm, pull the choke cable conduit back through the clamp (away from the arm) to remove any slack in the cable and tighten the screw securing the clamp.
