Greasing And Lubrication - Toro 74502 Operator's Manual

Warning
A blade that is bent or damaged could break apart
and could seriously injure or kill you or
bystanders.
Always replace bent or damaged blade with a
new blade.
Never file or create sharp notches in the edges
or surfaces of blade.
Removing the Blades
The blades must be replaced if a solid object is hit, if the
blade is out of balance, or the blade is bent. To ensure
optimum performance and continued safety conformance of
the machine, use genuine Toro replacement blades.
Replacement blades made by other manufacturers may
result in non-conformance with safety standards.
Hold the blade end using a rag or thickly-padded glove.
Remove the blade bolt, curved washer, and blade from the
spindle shaft (Fig. 26).

Sharpening the Blades
1. Use a file to sharpen the cutting edge at both ends of the
blade (Fig. 27). Maintain the original angle. The blade
retains its balance if the same amount of material is
removed from both cutting edges.

2. Check the balance of the blade by putting it on a blade
balancer (Fig. 28). If the blade stays in a horizontal
position, the blade is balanced and can be used. If the
blade is not balanced, file some metal off the end of the
sail area only (Fig. 26). Repeat this procedure until the
blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 26).
Important
The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the curved washer (cupped side toward the
blade) and blade bolt (Fig. 26). Torque the blade bolt to
35–65 ft.-lb. (47–88 N m).

Greasing and Lubrication

Lubricate the machine when shown on the Check Service
Reference Aid decal (Fig. 29) located beneath the seat.
Grease more frequently when operating conditions are
extremely dusty or sandy.
Grease with No. 2 general purpose lithium base or
molybdenum base grease.
How to Grease
1. Disengage the PTO, stop the engine, and remove the
key.
2. Clean the grease fittings with a rag. Make sure to scrape
any paint off of the front of the fitting(s).
3. Connect a grease gun to the fitting. Pump grease into
the fittings until grease begins to ooze out of the
bearings.
4. Wipe up any excess grease.
Where to Add Grease
Lubricate the grease fittings as shown on the Check Service
Reference Aid decal (Fig. 29) located beneath the seat.
