5.2.15 Adjust throttle lever tension (B&S Engines only).
a) Stop engine.
b) Tension in throttle levers can be increased or decreased by adjusting the
tightness of the lever pivot bolt which is located under the console.
6. TROUBLE SHOOTING
6.1 MOWER PULLING LEFT OR RIGHT.
a) Check idler arm pulleys and drive sheaves for mud and/or grass buildup.
Check for proper scraper position. See 5.2.4.
b) Check to be sure idler arms pivot freely, if not, lubricate idler pivots.
c) Check for worn drive belts.
NOTE: Wheel drive belts should be replaced as a set. A new belt should not
be mixed with a worn belt.
d) Check drive linkage adjustment - See 3.8.5.
e) Check for proper tire pressure in drive tires. Recommended tire pressure for
the drive tires is 12 to 16 psi. Higher pressures may be used in the tire on
the side that it pulls to (up to 28 psi).
Note: Different pressures may make mower cut unevenly.
6.2 MOWER CUTS UNEVENLY.
a) Check the drive tire pressure and tire circumference. See 5.1.9.
A more uniform cutting height may be obtained with higher tire pressure on
rough terrain. A lower tire pressure provides more flotation.
b) Check blade spacers, axle positions, and front caster spacers. They must be
equal on each blade.
c) Check caster 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.)
6.3 BLADES DO NOT STOP WHEN DISENGAGED.
a) Check the blade brake adjustment. (See Section 5.2.6)
b) Check the belt guide under the rear deck to make it is properly set. (See
Section 5.2.7) and check the blade engagement adjustment. (See Section
5.2.3)
6.4 ENGINE WILL NOT START.
a) Refer to Section 4.3.2 and follow directions to make sure engine is being
properly choked.
b) Make sure transmission is in "true neutral" position. See Sections 3.8.4 (c).
c) Check that the blades are disengaged and the blade switch is depressed (See
Section 5.2.12).
d) Check that there is fuel in the tank and that the fuel valve is open.
e) Check that the spark plug wire(s) is/are properly connected.
f) Check for loose or faulty wiring connections.
g) Check for corrosion at all wiring connections. Even minor corrosion may
cause a faulty connection. Clean connector terminals thoroughly, apply
dielectric grease and reconnect.
h) For 15 & 17 HP Kawasaki: Check that the key switch is in the “Run” position.
