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 tires; 13 psi/drive, 13 psi/pneumatic casters.
A more uniform cutting height may be obtained with higher tire pressure on rough terrain.
A lower tire pressure provides more flotation. Higher pressures in front casters may cause them to shimmy on hard surfaces.
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)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.
g)Check that the spark plug wires are properly connected.
h)Check for loose or faulty wiring connections.
i)Check for corrosion at all wiring connections. Even minor corrosion may cause a faulty connection. Clean connector terminals thoroughly with electrical contact cleaner, apply dielectric grease and reconnect.
NOTE: When disconnecting electrical connectors DO NOT pull on the wires to separate the connectors.
NOTE: After carefully checking the above steps, attempt to start the engine. If it does not start, contact your authorized Exmark service dealer.
IMPORTANT: It is essential that all operator safety mechanisms be connected and in proper operating condition prior to mower use.
When a problem occurs, do not overlook the simple causes. For example: starting problems could be caused by an empty fuel tank.
The following table lists some of the common causes of trouble. Do not attempt to service or replace major items or any items that call for special timing of adjustments procedures (such as valves, governor, etc.). Have this work done by your Engine Service Dealer.
