Frame Set Up
Checking the Carrier Frame and 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 54.
4. At the carrier frame cross channel, measure the
height at location A (Figure 54). This measurement
must be 1-5/16 inch (33 mm), plus or minus a 1/4
inch (6 mm).
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 54).
7. Align the carrier frame and engine deck to match
1-5/16 inch (33 mm), plus or minus a 1/4 inch (6
mm) at location A (Figure 54).
8. Tighten the carrier frame mounting bolts on both
sides of the machine.

2. Top of engine deck
5. Measure engine deck height at location B (Figure 55).
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 1/8 inch
(3 mm) to 3/8 inch (9 mm) over the length of 24 inches
(61 cm) on the carrier frame (Figure 56).
