Greasing The Front Caster Pivots; Greasing And Lubrication; How To Grease - Toro 74179 Operator's Manual

1. Park the machine on a level surface to ensure that the
fuel tanks drain completely. Then disengage the power
take off (PTO), set the parking brake, stop the engine,
and remove the key.
2. Close the fuel shut-off valve (Fig. 39).
3. Loosen the hose clamp at the fuel filter and slide it up
the fuel line away from the fuel filter (Fig. 39).
4. Pull the fuel line off of the fuel filter (Fig. 39).
5. Open the fuel shut-off valve for the left and right tanks.
Allow gasoline to drain into a gas can or drain pan
(Fig. 39).
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty.
6. Install the fuel line onto the fuel filter. Slide the hose
clamp close to the fuel filter to secure the fuel line
(Fig. 39).

Greasing the Front Caster Pivots

Lubricate the front caster pivots once a year.
1. Remove the dust cap and adjust the caster pivots. Keep
dust cap off until greasing is done. Refer to Adjusting

2. Remove the hex plug. Thread a grease zerk into hole.
3. Pump grease into zerk until it oozes out around top
bearing.
4. Remove grease zerk in hole. Reinstall hex plug and cap.
Greasing the Bearings
The cutting unit must be lubricated regularly; refer to the
Recommended Maintenance Schedule, page 26. Grease
with No. 2 general purpose lithium base or molybdenum
base grease.
1. Stop the engine, set the parking brake, remove the key
and disconnect the spark plug wire(s) from the spark
plug(s).
