Servicing The Engine Oil - Toro 74401 Operator's Manual

Servicing the Engine Oil

Change the oil after the first 8 operating hours and every
100 operating hours thereafter.
Oil Type: Detergent oil (API service SC, SD, SE, SF, SG,
or SH)
Crankcase Capacity: w/filter, 1.6 qt. (1.5 l)
Viscosity: See the table below.
USE THESE SAE VISCOSITY OILS
Checking the Oil Level
1. Park the machine on a level surface, disengage the PTO,
stop the engine, and remove the key.
2. Clean around the oil dipstick (Fig. 17) so that dirt
cannot fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 17).
4. Slide the oil dipstick fully into the filler tube, but do not
thread it onto the tube (Fig. 17). Pull the dipstick out
and look at the metal end. If the oil level is low, slowly
pour only enough oil into the filler tube to raise the
level to the "FULL" mark on the dipstick.
Important Do not overfill the crankcase with oil
because the engine may be damaged.

Changing and Draining the Oil
1. Start the engine and let it run for five minutes. This
warms the oil so that it drains better.
2. Park the machine so that the drain side is slightly lower
than the opposite side to ensure that the oil drains
completely. Then disengage the PTO, set the parking
brake, stop the engine, and remove the key.
3. Slide the drain hose over the oil drain valve (Fig. 18).
4. Place a pan below the oil drain hose. Use either a flat
screw driver, 3/8 inch (10 mm) wrench to open valve
(Fig. 18).
5. Rotate valve end counterclockwise to open valve
(Fig. 18).
6. When oil has drained completely, rotate valve end
clockwise to close the valve (Fig. 18).
7. Remove the drain hose.
Note: Dispose of the used oil at a certified recycling center.
