Adjusting the Mower Deck
Pitch
Cutting unit pitch is the difference in height-of-cut from the
front of the blade plane to the back of the blade plane. Toro
recommends a blade pitch of approximately 8 mm (5/16
inch). That is the back of the blade plane is 8 mm (5/16 inch)
higher than the front.
1. Position the machine on a level surface on the shop
floor.
2. Set the cutting unit to the desired height-of-cut, move
the throttle lever to the Slow position, stop the engine,
set the parking brake, and remove the ignition key.
3. Rotate the center blade so that it points straight
forward.
4. Using a short ruler, measure from the floor to the front
tip of the blade.
5. Rotate the same blade tip to the rear and measure from
the floor to the tip of the blade at the rear of the deck.

set to 8 mm (5/16 inch) (Figure 70).

Replacing the Grass Deflector

An uncovered discharge opening could allow the
machine to throw objects in the operator's or
bystander's direction and result in serious injury.
Also, contact with the blade could occur.
• Never operate the machine without a mulch kit
or grass deflector installed.
• Make sure the grass deflector is in the down
position.
