Belt Replacement
Refer to Figure 4-10 and Figure 4-11:
Replace belts which show signs of severe cuts, tears,
excessive weather checking and cracking or burns
caused by slipping. Slight raveling of belt covering does
not indicate failure, trim ravelings with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A
new belt, or one in good condition, should never run
against the bottomof thegroove. Replacethe pulley when
this is the case, otherwise belt will lose power and slip
excessively.
Never pry a belt to get it on a pulley as this will cut or
damage the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any ofthese will destroy thebelt composition in
a very short time.
Mower Blade Maintenance
Lift Jack Option
For easier blade maintenance a liftjack can be purchased
from your LandPride Dealerand easilyassembled toyour
mower. Refer to Figure 4-12.
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep them sharp, a dull
blade will tear rather than cut the grass, leaving a brown
ragged top on the grass within a few hours. A dull blade
also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
Never attempt to straighten a bent blade by heating, or
weld a cracked or broken blade as the blade may break
and cause serious injury.

DANGER!
Never work with blades while engine is running or deck clutch
is engaged. Always place deck clutch in the disengaged
position, place control levers in park position and turn engine
off. Block up mower when you must work under it. Do not use
jack as blocks. Jack is for lifting only. Separate blocks must be
used prior to servicing under mower. Wear gloves when
handling blades. Always check for blade damage if mower
strikes rock, branch or other foreign object during mowing!
Mower Blade Removal
Use a 3/4" wrench to remove the 1/2" cap screw holding
blade to spindle saddle from underneath.
Sharpen the blades on a grinder following pattern as
shown in Figure 4-13. Touch-up sharpening can be done
with a file.
Check the blades for balance following grinding. A
commercial balancing tool is available through most
hardware supply stores, or balancing can be done by
placing the blade on an inverted line punch or 1/2" bolt.
Blade should not lean or tilt. Spin the blade slowly, blade
should not wobble. If blade is out of balance, true it up
before reinstalling.
Lay the blade on a flat surface and check for distortion.
Replace any distorted blade. Refer Figure 4-14 and Figure
4-15 on next page.
