· Do not wear radio or music headphones while operating the machine. Safe operation requires your full attention.

· Older adults are involved in a large percentage of riding mower accidents involving injury. These operators should evaluate their ability to operate a mower safely enough to protect the operator and others from serious injury.

Park Safely

· Stop machine on a level surface, not on a slope.

· Disengage PTO.

· Lower attachments to the ground.

· Engage park brake.

· STOP engine.

· Remove key.

· Before you leave the operator's seat, wait for engine and all moving parts to STOP.

Rotating Blades are Dangerous - Protect Children and Prevent Accidents

Protect Children

· Never assume that children will remain where you last saw them. Children are attracted to mowing activity, stay alert to the presence of children.

· Keep children in the house when you are operating the machine.

· Turn machine off if a child enters the mowing area.

· Use extra care when you come to blind corners, shrubs, trees, or other objects that may block your vision.

· DO NOT carry or let children ride on machine or any attachment even with blades off. DO NOT tow children in a cart or trailer.

Help Prevent Serious Or Fatal Accidents:

· Be alert at all times, drive forward carefully. People ESPECIALLY CHILDREN can move quickly into the mowing area before you know it.

· Back carefully. Shut off PTO and look behind the machine carefully, ESPECIALLY FOR CHILDREN, before you back up.

· DO NOT mow in reverse unless it is absolutely necessary.

· Shut off PTO when you are not mowing.

· DO NOT operate machine if you are under the influence of drugs or alcohol.

Avoid Tipping

· DO NOT drive where machine could slip or tip.

· Stay alert for holes and other hidden hazards in the terrain.

· Keep away from drop-offs.

· Slow down before you make a sharp turn or operate on a slope.

· When pulling loads or using heavy equipment, use only approved hitches, limit loads to those you can safely control, and use counterweights or wheel weights when required per this manual or your attachment manual.

· Drive up and down a hill - not across. Be careful when you change direction on a slope.

· DO NOT stop when going up hill or down hill. If machine stops going up hill, STOP PTO and back down slowly.

· DO NOT mow wet grass. Reduced traction could cause sliding.

· DO NOT try to stabilize the machine by putting your foot on the ground.

Keep Riders Off

· Only allow the operator on the machine. Keep riders off.

· Riders on the machine or attachment may be struck by foreign objects or thrown off the machine causing serious injury.

· Riders obstruct the operator's view resulting in the machine being operated in an unsafe manner.

Wear Appropriate Clothing

· Wear close fitting clothing and safety equipment appropriate for the job.

· Loud noise can cause impairment or loss of hearing, wear a suitable protective device such as earplugs.

Stay Clear of Rotating Drivelines

Entanglement in rotating driveline can cause serious injury or death:

· Wear close fitting clothing.

· STOP the engine and be sure PTO driveline is stopped before getting near it.

Check Wheel Bolts

· A serious accident could occur causing serious injury if wheel bolts are not tight.

· Check wheel bolt tightness often during the first 100 hours of operation.

Transport Safely

· Use safety lights and devices. Slow moving machines when driven on public roads are hard to see, especially at night. Avoid personal injury or death resulting from a collision with a vehicle.

· Whenever driving on public roads, use flashing warning lights and turn signals according to local regulations. Extra flashing warning lights may need to be installed.

Practice Safe Maintenance

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

· Never lubricate, service, or adjust machine while it is moving. Keep safety devices in place and in working condition. Keep hardware tight.

· To prevent them from getting caught, keep hands, feet, clothing, jewelry, and long hair away from any moving parts.

· Before servicing machine, lower attachments to the ground. Disengage all power and stop the engine. Move hydraulic lift levers back and forth to relieve pressure. Lock park brake and remove the key. Let tractor cool.

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

· Never run engine unless park brake is locked.

· 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.

· Disconnect battery ground cable (-) before making adjustments on electrical systems or welding on tractor.

· Unauthorized modifications to the tractor may impair its function and safety.

Wear Appropriate Clothing

· Wear close fitting clothing and safety equipment appropriate for the job.

· Loud noise can cause impairment or loss of hearing, wear a suitable protective device such as earplugs.

· Do not wear radio or music headphones while servicing the machine. Safe service requires your full attention.

Stay Clear of Rotating Drivelines

Entanglement in rotating driveline can cause serious injury or death:

· STOP the engine and be sure PTO driveline is stopped before getting near it.

Handling Waste Product and Chemicals

· Waste products, such as, used oil, fuel, coolant, brake fluid, and batteries, can harm the environment and people.

· DO NOT use beverage containers for waste fluids-someone may drink from them.

· See your local Recycling Center or John Deere dealer to learn how to recycle or get rid of waste products.

· A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. See your John Deere dealer for the MSDS on chemical products used with your machine.

Avoid High Pressure Fluids

· Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly. Replace damaged hoses.

· Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

· Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

· If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere &

Company Medical Department in Moline, Illinois, U.S.A.

Transporting Tractor

M34229

Use a heavy-duty trailer to transport your tractor.

Drive tractor forward onto a trailer. Lower any attachments to trailer deck.

Lock park brake.

Fasten tractor to trailer with heavy-duty straps, chains, or cables. Both front and rear straps must be directed down and outward from tractor.

Trailer must have signs and lights required by law.

Mowing Tips

Before mowing, be sure deck is leveled and mower wheels are in the proper position.

When you mow an area for the first time, travel SLOW and cut HIGH so you can:

· Learn the terrain.

· Learn the best mowing pattern.

· Help prevent hitting objects hidden in the grass.

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

Mow grass often: Short grass clippings will decay quickly.

Mow at full throttle for best performance.

Use travel speed that fits conditions:

· Travel SLOW when you mow thick, tall grass.

· FAST travel or sharp turns may produce stripes or uneven cut: slow down.

· Travel at MODERATE speed when you mow a thin stand of grass.

Mow often enough so you cut only 1/3 of grass blade in one mowing. Cutting grass too short may kill grass and let weeds grow easily.

See your John Deere dealer for blades that will best fit your mowing conditions.

Aerate lawn to help stimulate soil organisms and root growth.

Trimming Tips

· Turn to left around trees, bushes, etc.

· Drive slowly. Avoid hitting trees, bushes, etc.

· If ground slopes up to a tree or bush, you may have to approach the tree or bush straight-on to avoid

scalping.

To Avoid Scalping

· Pay attention to the way you drive: you can eliminate scalping.

· If mower scalps easily, cutting height may be too low for ground conditions-especially on lawns

with many small mounds and ridges.

· Rear gauge wheels must be adjusted correctly.

· Drive over ridges and through shallow ditches straight-on, not at an angle.

Keep blades sharp: Dull blades will tear grass; tips of grass will then turn brown.

Check lawn regularly for uneven cut. If cut is uneven:

· LOOK: Mower may not be level.

· Slow down before you make a turn.

· Sharpen blades often.

Use thatcher (available from John Deere dealer) in late spring or summer to pull up dead grass and aerate ground.

For bagging information, see your Bagger Operator's Manual.

After Mowing

· Let engine cool-to prevent fire when you store mower.

· Clean top of deck, engine, and chute with compressed air, if possible-to help prevent buildup and

fire.

· Clean under deck with water under pressure-to prevent buildup and remove corrosive lawn

chemicals.

Bagging Tips

For best performance, bagger needs good airflow. To help increase airflow:

· Keep underside of deck and chute clean.

· Cut grass high.

· Mow at full throttle.

IMPORTANT: Avoid damage! Don't leave clippings in bag(s):

· Moisture may damage bag(s).

· Damp clippings are fire hazard.

· Clean bag(s) often with water from garden hose, from outside to inside of bag. Let bag(s) dry before

use.

LOOK: Check level of clippings in bags often. When bag(s) are full:

· Mower may leave a trail of clippings.

· Clippings may blow to side.

Bagging and Composting

Many communities will no longer haul lawn clippings and leaves to landfills. Bagging and composting clippings and leaves is one way to solve this problem.

Clippings from grass bag may also be used as mulch, or sheet compost, between garden rows and around trees and shrubs. This mulch will:

· Keep weeds from growing.

· Help soil keep moisture.

· Add nutrients to soil as it decays.

· Help keep soil temperature down during hot weather.

You may compost clippings and leaves in various ways. See garden magazines or clubs for information, or go to your local library for help.

Finished compost is crumbly. It is rich in soil nutrients, and can be spread on your lawn. Compost may also be worked into soil. It adds humus to soil and improves soil texture, making soil looser and easier to work.

Mulching Tips

Advantages:

· You do not have to rake or bag grass or leaves.

· Lawn holds moisture better during dry weather.

· Soil temperatures stay down during hot weather.

· Mulch adds nutrients to soil, and reduces need for fertilizer.

Mulching does not make thatch. Frequent shallow watering and fertilizer application produce thatch from roots that grow close to surface.

Be careful when you mulch leaves in Fall. Grass needs sunlight in Fall to help store food for Winter. A thick layer of mulched leaves can prevent sunlight from getting to grass and smother it. You may have to mow with grass bag to remove this layer.

Mulch only when the grass and leaves are dry.

Mulching wet or damp grass or leaves may cause problems:

· Clippings and leaves may build up on the underside of the mower deck.

· Cut grass and leaves may form clumps.

· Clippings and leaves may not be cut into small bits.

· Engine may work harder and use more fuel.

Cut only top 1/3 of grass at a time.

Use a different mowing pattern each time you mow. Overlap mowing paths 50-100 mm (2-4 in.).

Slow down. Mulching takes more power.

Keep blades sharp. Check them often.

Clean underside of deck after each use.
