Draining The Fuel Tank; Replacing The Fuel Filter - Toro 74590 Operator's Manual

Draining the Fuel Tank

Drain the fuel tank when you will not be using the tractor
for more than 30 days.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Park the tractor so that the left front side is slightly
lower than the right side to ensure that the fuel tank
drains completely.
2. Disengage the blades (PTO).
3. Set the parking brake.
4. Stop the engine and wait for all moving parts to stop.
5. Remove the ignition key.
6. Open the hood.
7. Squeeze the ends of the hose clamp together and slide it
up the fuel line toward the fuel tank (Fig. 31).
