7. TROUBLE SHOOTING
7.1 MOWER TRACKS TO LEFT OR RIGHT.
a) Check the drive tire pressure and tire circumference (See Section 5.1.12).
b) Turn knob on the right hydro control linkage in the direction that the mower
needs to be adjusted to. Turn the knob in 1/4 turn increments until the
mower tracks correctly.
7.2 MOWER CUTS UNEVENLY.
a) Check the drive tire pressure and tire circumference (See Section 5.1.12).
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 pins. Hairpin clips must be in the same hole position
on each support pin (See Section 5.2.1).
c) Check deck support alignment and check mounting brackets to be sure all
bolts are tight.
d) Check blades tip to tip for straightness. (They should be within 3/16”, or
one blade width from being in line.)
7.3 ENGINE WILL NOT START.
a) Make sure battery has a full charge (Electric start only). (See Section
5.1.25)
b) Check that choke is in the “ON” position for a cold engine or in the “OFF”
position for a warm engine (See Section 4.3.2).
NOTE: Kawasaki engines may need to be choked even when warm.
c) Make sure the key switch is in the “ON” position (15, 17 & 19 HP Kawasaki
Manual start).
d) Make sure the speed control lever is in the “true neutral” position (See
Section 5.2.6).
e) Check that the PTO is disengaged and the PTO switch is depressed.
f) Make sure the OPC levers are depressed. (Electric start only)
g) Check that there is fuel in the tank and that the fuel valve is open.
h) Check that the spark plug wire(s) are properly connected.
i) Check for loose or faulty wiring connections. If it is necessary to disconnect
wire connectors, Do Not pull on the wires while disconnecting.
j) 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.
IMPORTANT: It is essential that all operator safety mechanisms be
connected and in proper operating condition prior to mower use.
NOTE: After carefully checking the above steps, attempt to start the
engine. If it does not start, contact your authorized Exmark service dealer.
ENGINE TROUBLESHOOTING
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 or adjustment procedures (such as valves, governor, etc.). Have this
work done by your Engine Service Dealer.
