MAINTENANCE
CUTTER SHAFT
Routinely inspect cutter shaft for and replace any worn or damaged blades. When replacing worn blades
always replace blade set directly opposite, (180 degrees) otherwise cutter shaft will be out of balance. Inspect
bushing and bolt for wear and replace if necessary. Remove any debris which may become entangled around
cutter shaft or bearings. Stop machine at first sign of excessive vibration and inspect cutter shaft and bearings.
BLADE REPLACEMENT
• Remove locknut (item 1), bolt (item 2), and
inspect bushing (item 3) and bolt for wear.
Replace if worn.
• Place new knives on bushing and insert between
reel clip.
BELT ADJUSTMENT AND REPLACEMENT
To adjust belt, loosen both pivot bolts slightly (item 1),
and tighten nut on tension rod (item 2), which pivots
drive assembly forward to tension belt. Correctly ten-
sioned belt should require a maximum of 85 lbs force
across entire band to deflect belt 3/8" as illustrated.
Do not over-tension belt as excessive loads will be
placed on bearings. Tighten pivot bolts and lock in
place with jam nuts.
To replace belt, loosen both pivot bolts (item 1), undo
nuts from tension rod (item 2) and rotate drive tube
assembly toward deck. Install new banded belt and
rotate drive assembly forward by placing pry-bar in
tube on front of assembly. Feed tension rod through
slot as the tube is rotated forward and attach washer
and adjustment nut. Before tensioning belt lightly
tighten pivot bolts to remove play from pivot points.
Tension belt as outlined above. Always check belt
alignment after installing new belt.
