Matching the Height of Cut
1. Lower the mower to the 76 mm (3 inches) height-of-cut
position.
2. Position the right blade front-to-rear.
3. Measure the right blade at location C, from a level
surface to the cutting edge of the blade tip, and record
this measurement (Figure
Note: The measurement at location C needs to be
within an 3 mm (1/8 inch) of the 76 mm (3 inches)
height-of-cut setting. If it is not correct, proceed to
the following steps.
4. Loosen the jam nuts at both ends of the turnbuckle
(Figure 87).
Note: The end of the turnbuckle with the groove
machined in it has left threads
5. Adjust the turnbuckle to raise or lower the deck height
to achieve 76 mm (3 inches) at location C.
6. Tighten the jam nuts at both ends of the turnbuckle.
7. Check and ensure that the mower-deck lift lever latches
into the transport position.
Note: If it does not latch into the transport position,
adjust the turn buckle until it latches into the transport
position.
8. Tighten the jam nuts.

Adjusting the Compression Spring
Note: Adjusting the compression spring alters how much
the deck floats and how much effort it takes to lift the deck
when using the height-of-cut handle.
•
More spring compression reduces the handle lift force
required and causes the deck to float more.
•
Less spring compression increases the handle lift force
required and causes the deck to float less.
1. Raise the deck-lift lever and lock it into the transport
position.
2. Check the length of the compression spring.
Note: Nominal length is 28.2 cm (11-1/8 inches) for
91 cm (36 inch) mower decks and 25.7 cm (10-1/8
inches) for 102 cm (40 inch) mower decks
3. Adjust this distance, by loosening the spring-jam nut
and turning the nut in front of each spring
4. Lock the nut into position by tightening the spring-jam
nut (Figure 88).
1. 25.7 cm (10-1/8 inch) for
102 cm (40 inch) mower
decks and 28.2 cm (11-1/8
inch) for 91 cm (36 inch)
mower decks
