Checking The Mower Deck Front-To-Rear Pitch - Toro 30074 Operator's Manual

1. Carrier Frame
2. 1/4-3/8 inch (6-10 mm)
pitch over 24 inch (61 cm)
length
3. 24 inches (61 cm)
2. Measure carrier frame height at location A
(Figure 64).
3. Measure carrier frame height at location B
(Figure 64).
4. The height at location A must be a 1/4-3/8 inch (6
mm -10 mm) lower than location B (Figure 64).
5. If the carrier frame is not correct, move caster
spacers to make it a 1/4-3/8 inch (6 -10 mm) pitch
(Figure 64). Move spacers from top or bottom to
make the correct pitch.
6. The tire pressure may also be adjusted slightly to
make a 1/4 inch (6 mm) pitch.
Checking the Carrier Frame
Side-to-Side Height
The carrier frame needs to be parallel side-to-side from
the ground.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Adjust the tire pressure in the
rear tires to specifications; refer to
Drive System Maintenance (page 30) .
4. Measure carrier frame height at location A
(Figure 65).
5. Measure carrier frame height at location B
(Figure 65).
6. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to
Figure 64

Front-to-Rear Pitch
1. Adjust the tire pressure in the
rear tires to specifications; refer to
Drive System Maintenance (page 30) .
2. Position one blade front-to-rear. Measure at A and
B locations from a level surface to the cutting edge
of the blade tips (Figure 66 or Figure 67). For 36
inch mower decks use Figure 67.
3. The mower blade should be a 1/4 inch (6 mm) lower
in front at A than in the rear at B. Rotate blades and
repeat for other blades. If it is not correct, proceed
to Changing the Deck Front-to-Rear Pitch.
