9. Repeat 7 and 8 on the opposite side of the cutter
deck.
10. Check the front-to-rear blade slope; refer to
Adjusting the Front-to-Rear Blade Slope.
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).

7. Install the end of the rod into the hole in the cutter
deck mount and secure it with the washer and
hairpin cotter.
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.

10. Slightly loosen the front pivot plate mounting bolts
(Figure 63).

Eyebolt locknut
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).
