OPERATION
DRIVE CONTROL
(See Fig. 6)
*
Self-propelling
is controlled by holding the operator
presence control bar down to the handle and pulling
either drive control lever rearward to the handle. The
further toward the handle a lever is pulled, the faster
the unit will travel.
Forward motion will stop when either the operator pres-
ence control bar or a drive control lever are released. To
stop forward motion without stopping blade, release a
drive control lever only. Hold operator presence control
bar down against handle to continue mowing without
self-propelling.
NOTE: If after releasing the drive control the mower will
not roll backwards,
push the mower forward slightly to
disengage drive wheels.
