Checking the Front-to-Rear Blade Slope

Check the front-to-rear blade slope any time you install the mower.

1. Check the tire pressure on the tractor. Refer to the

tractor Operator’s Manual.

2. Position one blade front-to-rear (Fig. 15). Measure at C and either D location (Fig. 15) from a level surface to the cutting edge of the blade tips (Fig. 16).

3. The mower blade should be 1/8–1/4 inch (4–7 mm) lower in front at C than in the rear at D. Rotate the

blades and repeat for the other blades.

4. If it is not correct, proceed to Changing the mower Front–to–Rear Pitch.

Transport Height Adjustment

Transport height is adjusted to stabilize the mower in the up, locked position.

1. Raise the mower to the highest height–of–cut and check

if the transport level stops contact the bottom of the draft bars (Fig. 18).

2. If needed, loosen and adjust the transport level stops so

they just contact the bottom of the draft bars (Fig. 18).
