JOHN DEERE 185 (01) PDF MANUAL

A signal word – DANGER, WARNING, or CAUTION – is used with the safety-alert symbol. DANGER identifies the most serious hazards. Safety signs with the signal word DANGER or WARNING are typically near specific hazards. General precautions are listed on CAUTION safety signs. CAUTION also calls attention to safety messages in this manual.

Keep Riders Off Machine: Only allow the operator on the machine. Keep riders off. Riders on the machine are subject to injury such as being struck by foreign objects and being thrown off the machine. Riders also obstruct the operator’s view resulting in the machine being operated in an unsafe manner.

Protect Children: Keep children and others away when you operate the machine. Before you back up, stop the PTO and look behind the tractor for children. Do not let children operate the tractor. Never carry children or let them ride on the tractor, mower, or any attachment.

Do not drive where the machine could slip or tip.

Stay alert for holes, rocks, and roots in the terrain, and other hidden hazards. Keep away from drop-offs.

Slow down before you make a sharp turn.

Use care when pulling loads or using heavy equipment. Use only approved drawbar hitch points and limit loads to those you can safely control. Use counterweights or wheel weights when suggested in this operator’s manual.

Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tipping or loss of control. Be especially cautious when changing direction on slopes.

Do not stop or start suddenly when going uphill or downhill.

If the machine stops going up a hill, stop the PTO and back down slowly.

To park the tractor safely:

1. Move the shift lever to the “N” (Neutral) position.

2. Disengage PTO’s.

3. Lower equipment to the ground.

4. Engage the park brake.

5. Stop the engine.

6. Remove the key.

Before you leave the operator’s seat, wait for the engine and attachment parts to stop moving.

Handle fuel with care; it is highly flammable. Do not refuel the machine while smoking or when near an open flame or sparks.

Always stop the engine before refueling the machine. Fill the fuel tank outdoors.

Prevent fires by keeping the machine clean of accumulated trash, grease, and debris. Always clean up spilled fuel.

Understand the service procedure before doing work. Keep the area clean and dry.

Never lubricate or service the machine while it is moving. Keep hands, feet, and clothing from power-driven parts. Disengage all power and operate controls to relieve pressure. Lower equipment to the ground. Stop the engine. Remove the key. Allow the machine to cool.

Securely support any machine elements that must be raised for service work.

Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts. Remove any buildup of grease, oil, or debris.

6. Remove the key.

7. Wait for the mower blades to stop.

NOTE: If the engine and mower are running, the engine and mower must stop when you get off the operator’s seat.

Low-lift blades: for dusty or dirty conditions, not for bagging.

Medium-lift blades: standard blade for use without a bagger. Also good to use if you bag an average stand of grass regularly.

High-lift blades: for cutting and bagging thick, tall grass and/or leaves.

Cut grass only when it is dry. Wet grass may plug the mower and leave a trail of grass clumps.

Mow grass often. Short grass clippings will decay quickly.

Run the engine at wide open throttle for optimum cut quality.

Cutting grass too short may kill grass and let weeds grow easily.

Keep blades sharp. A dull blade will tear grass, and the tips of the grass will then turn brown.

Use a slow travel speed (not engine speed) before you make a turn. Short, fast turns may scuff the ground and pull grass out by the roots.

First Method:

1. Adjust the cutting height of the mower to mow tall grass (A) to half height (B).

2. Before the second pass, adjust the cutting height so you can mow at the desired height (C).

Second Method:

1. Mow at the desired height at slow travel speed, full width OR

2. Mow at the desired height using only half of the cutting width.

Read the CAUTION and WARNING safety signs attached to the hopper top, bags, and chute.

1. Stop the mower and tractor engine before you remove or install grass bags or the chute.

2. Do not operate on steep slopes.

3. Do not change ground travel speed when you operate on inclines.

4. Do not operate uphill with grass bags full of leaves or clippings.

5. Do not leave grass or leaves in bags overnight. Do not store the tractor with grass or leaves in bags.

1. Mow and bag grass when it is dry and not too tall or dense.

2. Operate the tractor at a slow travel speed and the engine at maximum speed.

3. Keep the mower deck, bagging chute, hopper top screen, and bags clean.

4. Install the correct blade(s).

5. Operate the mower in the higher cutting positions to permit maximum air flow. Mow grass twice if it is longer than normal.

6. Empty the bags often to prevent plugging.

7. Put plastic garbage bags inside cloth bags to facilitate disposal of grass or leaves.

1. Pull down the rubber latch (A) to remove it from the retainer.

2. Raise the hopper top.

NOTE: There should be 1-in. (25.4 mm) stretch in the latch when connecting to the retainer. If necessary, raise the hopper top and remove bags to adjust the retainer for correct latch stretch. Place flat washers between the retainer and bag holder in position (B) to attain proper stretch.

3. Grasp the bag support frame and lift the bag off the post hanger.

NOTE: If the hopper top will not stay up when opened, tighten the nuts (A) on the two hinge bolts that attach the hopper top to the support post. Do not overtighten the nuts or the hopper top will be difficult to open and close.

4. Grasp the cord on the bottom of the bag to empty it.

Using Front Weights:

CAUTION: Tractor weights improve stability in most slope operations. Add front weights for better front-end stability and steering.

Install front weights for better stability and steering control when you use equipment such as the rear-mounted grass bagger or dump cart. A front weight weighs 18 kg (40 lb). See your John Deere dealer for weights.

Using Rear Weights:

Use rear weights to reduce rear wheel slip and to improve braking when equipment such as a snowblower or front blade is installed. Remove rear weights to use the drawbar. A rear weight weighs 18 kg (40 lb). See your John Deere dealer for weights.
