Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 27).
Important The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the flat washer, lock washer and blade bolt
(Fig. 27). Torque the blade bolt to 85–110 ft-lb
(115–150 N m).
Important Make sure blade is torqued to 85–110 ft-lb
(115–150 N m).

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. 30) 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. 30).
4. Slide the oil dipstick fully into the filler tube, but do
not thread it onto the tube. Pull the dipstick out and
look at the metal end (Fig. 31). If the oil level is low,
slowly pour only enough oil into the filler tube to raise
the level to, but not over, the “F” mark on the dipstick.

Important Do not overfill the crankcase with oil
because the engine may be damaged. Do not run engine
with oil below the low mark 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.
