Checking The Mower Deck Front-To-Rear Pitch - Toro 39494 Operator's Manual

Checking the Carrier Frame
Front-to-Rear Pitch
The carrier frame must have a pitch between 1/8 inch
(3 mm) to 3/8 inch (9 mm) over the length of 24 inches
(61 cm) on the carrier frame (Figure 59).
1. Measure out 24 inches (61 cm) on the carrier frame
(Figure 59).

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 59).
3. Measure carrier frame height at location B
(Figure 59).
4. The height at location A must be an 1/8-3/8 inch (3
mm -10 mm) lower than location B (Figure 59).
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 59). 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 32 .

4. Measure carrier frame height at location A
(Figure 60).
5. Measure carrier frame height at location B
(Figure 60).
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.

Front-to-Rear Pitch
1. Adjust the tire pressure in the rear tires to
specifications; refer to Drive System Maintenance.
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 61 and Figure 62).
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.
