POWER FOR DRIVING
To effect transmission of motive power to
the cutting blade, two V-belts are used.
The primary drive pulley which
is located
above the drive disc
is keyed to the engine
crankshaft.
A short V-belt runs from this
primary pulley to the upper pulley on the
intermediate spindle.
A' longer V-belt con-
nects the lower pulley on the intermediate
spindle to the blade pulley on the blade
shaft, driving the cutting blade.
THE MOWER BLADE
Two idler pulleys are used in the blade
drive system
as illustrated below. A blade
brake applied to the short belt (rear) stops
the blade. The brake is applied by the con-
trol lever.
As .the mower pan is disassembled, examine
rods and suspension assembly for damage
or distortion, for bent or misshapened rods,
bearings or bushings
which are damaged or
worn, dry bearings, and shafts which are
gouged or ringed.
