Federal law states that batteries should not be placed in the garbage. Management and disposal practices must be within relevant federal, state, or local laws.

7.TROUBLE SHOOTING

7.1MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).

a)Refer to Tracking Adjustment Section 4.1.3.

b)Check air pressure in drive tires; 13 psi Semi-pneumatic casters do not require inflation.

c)Check reverse indicator and motion control linkage adjustment. See section 5.2.12 and 5.2.13.

7.2MOWER CUTS UNEVENLY.

a)Check air pressure in drive tires; 13 psi. Semi-pneumatic casters do not require inflation.

A more uniform cutting height may be obtained with higher tire pressure on rough terrain.

A lower tire pressure provides more flotation.

b)Check deck support chains.

c)Check deck leveling (See Adjustments Section 5.2.2.)

Note: The front of the mower deck will be approximately 1/4” lower than the back of the mower deck. This is the “rake” of the deck.

d)Check blades tip to tip for straightness (they should be within 3/16" or one blade width from being in line.)

7.3ENGINE WILL NOT START.

a)Make sure the battery has a full charge. See section 5.1.3 for charging instructions.

b)For all units except Kohler EFI: Be sure the throttle control is midway between the “SLOW” and “FAST” positions, and the choke is in the “ON” position for a cold engine or the “OFF” position for a warm engine.

c)Make sure there is fuel in the fuel tank and that the fuel valve is open.

d)Be sure the seat switch is properly adjusted. See Section 5.2.6.

e)Make sure the parking brake is set and motion control levers are moved out (neutral lock position).

f)Check that the PTO is disengaged.
