3.7 LEVELING THE MOWER ______________________________________________________
Leaving a mower running and
unattended can be fatal or
cause serious injury.
To prevent injury, lower the mower deck to the
ground, disengage all drives, engage parking
brake and stop engine before making any
adjustments.
1.
Park the mower on a flat level surface.
2.
Measure from the ground to the front of the deck.
With respect to the height at this point the rear of
the deck must be 3/16 inch (4.76mm) higher than
the front.
3.
Adjust the rear lift chains to compensate for any
difference in height. See Section 6.9.
3.8 BLADE INSPECTION _________________________________________________________
1.
The blades should be inspected every 8 hours or
whenever the mower has struck a hard object to
ensure they are in good operating condition. Blades
showing any bends, cracks or grooves must be
replaced.
2.
Any of the above conditions can cause a piece of
the blade to break away and be hurled from the
mower; causing very serious injury to bystanders or
property damage.
3.
A bent blade could have a microscopic crack (A)
that can grow and cause a piece of the blade to
break. Bent blades will also create vibration and
other stress on the machinery.
4.
Dust or sand particles can wear a groove in the
blade (B) between the air vanes and the flat portion
of the blade. Continued use will rapidly develop the
groove into a crack (C), permitting a piece of the
vane to brake off.

3.9 BLADE REMOVAL
______________________________________________________________________
1.
Raise the cutting deck to the highest cutting height.
2.
Stop the mower, set the parking brake, stop the
engine, remove the ignition key, and disconnect the
spark plug wires.
3.
Chock the rear wheels and raise the front end of the
mower.
4.
Support the front end on jack stands.
5.
Remove the blade/bolt assembly from the bottom of
the deck. Place a wooden block between the blade
and the mower housing to prevent the blade from
turning.
Always support the deck
under all four corners (use
appropiate height blocks) prior to removing the
blade bolt to change blades.
3.10 REPLACING BLADE
___________________________________________________________________
1.
Make certain the air vanes of the blade point toward
the mower housing. Assemble blade to cutter hous-
ing using the 5/8-18 x 2-3/4” blade bolt, blade
washer, and 2 spacer washers as shown.
2.
Torque Blade Bolt to 75-85 ft. lb. (101.7 -115.3 Nm).
