sure, align blades in parallel with mower center- line, (i.e. front to back).

5.

Measure blade-to-ground height at the front tip

 

of the left blade. Be sure to measure at the

 

blade tip with the blades arranged in proper

 

position.

6.

To level the deck, (side to side) adjust the

 

threaded link at the left side of the deck (Point B)

 

so that the blade-to-ground height at the right

 

front blade tip matches that of the left front blade

 

tip. This is done by loosening the jam nuts on

 

the threaded link and tightening the lower nut to

 

raise the deck and loosening the nut to lower the

 

deck.

7.

Measure the blade-to-ground height at the right

 

rear blade tip. Again be sure to measure at the

 

blade tip at the rear of the right blade when

aligned along the mower centerline. The blade-

 

to-ground height at the rear of the blade tip

 

should be 1/8" to 1/4” higher than the front tip.

 

This is referred to as blade pitch. The same

 

height difference should be true for the left

 

blade, measured front and back.

8.

To adjust the blade pitch, the deck pitch must be

 

adjusted. Loosen the inner jam nuts at the rear

 

of the horizontal threaded links. Start at Point C

 

to raise the rear of the deck, tighten the front

 

outer jam nut to raise the front of the deck.

 

Adjust the rear jam nut at Point C to take the

 

slack out of the threaded link.

9.

The final adjustment would be to take the “slack”

 

out of the front linkage (Point C) by adjusting the

 

jam nuts on the threaded link. Loosen the jam

 

nuts and tighten the inner nut to remove “slack”.

10.

In many cases it will be necessary to adjust

 

deck height using both eyebolt adjustments and

 

pitch adjustment to achieve the correct blade-to-

 

ground heights. If you remember that the front

 

right blade tip adjustment is fixed and you level

 

to that height, adjusting the decks will be simpli-

 

fied.
