Setting up the Frame
Checking the Carrier Frame and the
Engine-Deck Alignment
Note:
Misalignment can cause excess wear on the PTO-drive
belt.
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. Place a long straight edge on top of the engine deck as
shown in
Figure 67 .
4. At the carrier frame cross channel, measure the height
at location
A ( Figure 67 ). This measurement must be
33 mm (1-5/16 inches), plus or minus 6 mm (1/4 inch).
5. If the height at location A is not correct, adjustment
is needed.
6. Loosen the carrier frame mounting bolts on both sides
of the machine (
Figure 67 ).
7. Align the carrier frame and engine deck to match 33
mm (1-5/16 inches), plus or minus 6 mm (1/4 inch)
at location
A ( Figure 67 ).
8. Tighten the carrier frame mounting bolts on both sides
of the machine.

Checking the Engine-Deck Height
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
Checking the Tire Pressure (page 34) .
4. Measure engine-deck height at location A ( Figure 68 ).
5. Measure engine-deck height at location B ( Figure 68 ).
6. If the height at location A and B are not the same,
change tire pressure slightly to make them the same.

Checking the Carrier Frame
Front-to-Rear Pitch
The carrier frame must have a pitch between 3 mm (1/8 inch)
to 9 mm (3/8 inch) over the length of 61 cm (24 inches) on
the carrier frame (
Figure 69 ).
1. Measure out 61 cm (24 inches) on the carrier frame
(
Figure 69 ).

2. Measure carrier-frame height at location A ( Figure 69 ).
