Adjusting the Front-to-Rear Blade Slope

Check the front-to-rear blade slope whenever you install the cutter deck. Before you check the slope, set the air pressure in the tyres to the recommended level; refer to Checking the Tyre Pressure. If the front of the cutter deck is not within a range of 1/8 to 3/8 inch (3 to 10

mm)lower than the rear of the cutter deck, adjust the blade slope as follows:

1.Park the tractor on a level surface.

2.Disengage the blade control (PTO) and set the parking brake.

3.Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

4.Check and adjust the side-to-side blade level if you have not checked the setting; refer to Leveling the Cutter Deck from Side-to-Side.

5.Move the height-of-cut lever into the “C” notch.

6.Measure the length of the rod extending out of the front of the adjusting block on the sides of the chassis (Figure 61). If the rod length is not 5/8 inch (16 mm), remove the hairpin cotter and washer from the end of the rod (Figure 61) and turn the rod until it extends out 5/8 inch (16 mm).

8.Repeat 6 and 7 on the opposite side of the cutter deck.

9.Check the front-to-rear slope by measuring between the bottom of the cutter deck (front center and rear center) and the flat surface (Figure 62). If the front is not within a range of 1/8 to 3/8 inch (3 to 10 mm) lower than the rear, an adjust it.

11.Rotate the locknuts on the eyebolts to change the adjustment (Figure 63).

Note: To raise the front of the cutter deck, tighten the eyebolt locknuts; to lower the front of the cutter deck, loosen the eyebolt locknuts.

12.After adjusting both of the eyebolt locknuts evenly, check the front-to-rear slope again. Continue adjusting the eyebolts until the front blade tip is 0 to 3/8 inch (0 to 9 mm) lower than the rear blade tip (Figure 63).
