KNOB REMOVAL & INSTALLATION
Shift Lever Knob (Gear Models Only)
1. The shift lever knob is pressed onto the end of
ground speed control lever and may be removed by
placing a 7/16” open end box wrench under the knob
and tapping the wrench outward with a hammer or
rubber mallet (Figure 1).
Knobs that resist removal with this method may be
heated with a heat gun or blow dryer to expand the
I.D. of the knob slightly and separate it from the end
of the ground speed control lever.
NOTE: Do not overheat the knob as this may distort the
part or cause melting, and could prevent a secure fit
when reattaching the knob. Use a low heat setting when
using a heat gun, and keep the gun 4-6’’ away from the
knob while moving back and forth to provide even heat-
ing.
2. Slide the knob off the ground speed control lever, and
check for cracks or excessive wear–replace as nec-
essary.
Parking Brake Knob
The parking brake knob (A, Figure 2) is threaded onto
the parking brake rod. Turn the knob counter clockwise
to remove it.
Throttle Control Knob
The throttle control knob (Figure 3) snaps onto the throt-
tle lever. To remove the knob, pull it straight off the
lever. To reinstall, press onto the lever and drive into
place with a rubber mallet.
WARNING
Before beginning any service work, turn the PTO
off,set the parking brake, turn the ignition switch
off, remove the key, disconnect the spark plug
wire, and disconnect the negative battery cable.
WARNING
Never use a heat gun or blow dryer if flammable
vapors are present, as the heating element could
ignite the vapor and cause a fire or explosion.
