Checking The Mower Deck Front-To-Rear Pitch - Toro 30486 Operator's Manual

1. Carrier Frame
2. 1/8 inch -3/8 inch (3-10
mm) pitch over 24 inch (61
cm) length
3. 24 inches (61 cm)
2. Measure carrier frame height at location A
(Figure 71).
3. Measure carrier frame height at location B
(Figure 71).
4. The height at location A must be an 1/8-3/8 inch (3
mm -10 mm) lower than location B (Figure 71).
5. If the carrier frame is not correct, move caster
spacers to make it an 1/8-3/8 inch (3 -10 mm) pitch
(Figure 71). Move spacers from top or bottom to
make the correct pitch.
6. The tire pressure may also be adjusted slightly to
make an 1/8-3/8 inch (3 -10 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 34) .
4. Measure carrier frame height at location A
(Figure 72).
5. Measure carrier frame height at location B
(Figure 72).
6. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to
make it level. The tire pressure may also be adjusted
slightly to make it level.

Checking the Mower Deck
Front-to-Rear Pitch
1. Adjust the tire pressure in the
rear tires to specifications; refer to
Drive System Maintenance (page 34) .
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 73 or Figure 74). For 36 inch
mower decks use Figure 74.
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.
