Transporting Machine on Trailer

Be sure trailer has all the necessary lights and signs required by law.

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

· Park trailer on a level surface.

· Use of a trailer with sides is recommended.

· Keep wheels away from drop-offs and edges.

· Back slowly and in a straight line.

IMPORTANT: Avoid damage! Transmission damage may occur if the machine is towed or moved incorrectly:

· Move unit by hand only.

· Do not use another vehicle to move unit.

· Do not tow unit.


1. Park trailer on level surface.

2. Drive machine onto heavy-duty trailer.

3. Lower mower to trailer deck.

4. Lock park brake.

5. Turn off machine and remove key.

Using Wheel Weights

· Install front wheel weights for added stability and steering control when you use equipment such as the rear-mounted grass bagger.

· Install rear wheel weights when using the front blade.

· Remove wheel weights when not required.

Mowing Tips

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

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

· Cutting grass too short may kill grass and let weeds grow easily. The suggested finished cut height range is 44 to 70 mm (1.75 to 2.75 in.).

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

· When using the Freedom42 Mulching Mower: Shorter cut heights will provide better cut quality, but may leave noticeable clippings. Higher cut heights will reduce clippings, but cut quality may decline.

· Do not mow wet grass. Wet cutting conditions will not adversely affect the cutting performance of the Freedom42 Mulching Mower.

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

· Mow with engine at full throttle.

· Adjust travel speed to match mowing conditions:

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

· Travel at moderate speed when you mow thin grass.

John Deere Lt150 Parts Diagram

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

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

MIF

· When using the Freedom42 deck: Mow around the outside twice, then mow inside in straight passes. Best cut is achieved when mowing in a straight line.


P000149

· When mulching near pavement, overlap the pavement by 50 mm (2 in.) to allow clippings to dispense over grass.

· 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.

John Deere Lt150 For Sale

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