Testing Safety Systems


M199903121420136

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Move the vehicle to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

ˇ Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.

ˇ Allow fresh outside air into the work area to clear the exhaust fumes out.

Use the following checkout procedure to check for normal operation of machine.

If there is a malfunction during one of these procedures, Do not operate machine. See your John Deere dealer for service.

Perform these tests in a clear open area. Keep bystanders away.

Adjusting Cutting Height

c CAUTION: Avoid injury! Before you adjust mower:

ˇ Stop engine.

ˇ Lock park brake.

NOTE: Because mowing conditions vary, along with the condition of your mower, actual cutting height may be different than shown by pointer (B). You may have to measure height of grass in several places to learn actual cutting height.

Cutting height can be adjusted from 25-102 mm (1-4 in.).


M92975

Turn crank (A) clockwise to raise the mower and counterclockwise to lower the mower.

NOTE: When changing mower deck height, it might also be necessary to change the location of the Weight Transfer Cable. Check label (C) when changing mower deck height. This will ensure proper operation of the Weight Transfer System.

Using The Mower

IMPORTANT: Avoid damage! The PTO clutch may be damaged if the mower is engaged with the engine is at a fast throttle speed.

ˇ Engage mower at one-third to one-half throttle.


To engage the mower:

NOTE: When mower is new or engine is not fully warmed up, you may need faster engine speed.


M47992

M62303

2. Attach cable with drilled pin (D) in correct hole for cutting height and install spring locking pin (E).

Mowing Tips

The following recommendations will produce the best lawn cut quality and appearance:

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

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

ˇ Adjust cutting height to remove only 1/3 of the grass at a time.

ˇ Mow grass often. Short grass clippings will decay quickly.

ˇ Mow with engine at full throttle.

ˇ Adjust travel speed to match mowing conditions:

ˇ Travel at slow speed when you mow thick, tall grass, make sharp turns or trim around objects.

ˇ Travel at moderate speed when you mow thin grass.

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

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

ˇ A thick layer of mulched leave can prevent sunlight from getting to grass and smother it. Taller grass heights allow mulched leaves to dispense easier in lawn. Mulch leaves several times if needed.

ˇ Use a thatcher in late spring or summer to pull up dead grass and aerate ground.

Transporting Machine

c CAUTION: Avoid injury! Use extra care when loading or unloading the machine into a trailer or a truck.

Use a heavy-duty trailer to transport your machine.

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

Lock park brake. Remove the key. Block the wheels.

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

Trailer must have signs and lights required by law.

Towing Loads

c CAUTION: Avoid injury! Your Front Mower is not designed to pull heavy loads on slopes.

ˇ A heavy load may cause you to lose control of steering, and may result in personal injury.

ˇ Do not tow children in a cart or trailer. Tow only light loads slowly on level ground.

ˇ Look for children before you back up a load.

Use drawbar to pull light trailers, carts, or other light attachments.

Do not tow more than 225 kg (496 lb) gross weight.

Tow only loads you can safely control.

Do not tow a load on a slope.
