deck as shown in Figure 146.
3. At the carrier frame cross tube, measure location
A height (Figure 146). This measurement must be
2-13/16 in. (71mm), plus or minus 1/4 in. (6mm).
4. If the height at location A is not correct,
adjustment is needed.
5. Loosen the carrier frame mounting bolts on both
sides of the machine (Figure 146).
6. Align the carrier frame and engine deck to obtain
2-13/16 in. (71mm), plus or minus 1/4 in. (6mm) at
