Adjusting the Front-to-Rear Mower
Pitch
1. P osition the right blade front-to-rear
( Figure 64 ).
2. Measure the right blade at the A location, from
a lev el surface to the cutting edg e of the blade
tip ( Figure 64 ).

1. Measure here from blade
to hard surface
2. Measure at A and B
3. R ecord this measurement.
4. Measure the right blade at the B location, from
a lev el surface to the cutting edg e of the blade
tip ( Figure 64 ).
5. R ecord this measurement.
6. T he mo w er blade should be a 1/4 to 3/8 inc h
(6 to 10 mm) lo w er at position A than at
position B ( Figure 64 ). If it is not cor rect,
proceed to the follo wing ste ps .
Note: Both of the front swi v els need to be
adjusted the same amount to maintain equal
c hain tension.
7. Loosen the front swi v el jam n uts , at the front
of the right and left swi v els , appro ximately a
1/2 inc h (13 mm) ( Figure 63 ).
8. Adjust the lift n uts on both the left and the
right side of the mac hine to ac hiev e 1/4 to
3/8 inc h (6 to 10 mm) lo w er in front at A than
in the rear at B ( Figure 63 ).
9. Tighten both swi v el jam n uts ag ainst the front
swi v el to loc k the height.
10. Chec k to mak e sure there is equal tension on
the c hains and adjust ag ain if needed.
Adjusting the Compression Spring
1. Raise the mo w er lift lev er to the transpor t
position.
2. Chec k the distance betw een the tw o larg e
w ashers , it needs to be 11-1/8 inc hes (28.2 cm)
( Figure 65 ).
3. Adjust this distance , b y loosening the spring
jam n ut and tur ning the n ut in front of eac h
spring ( Figure 65 ).
Note: T ur ning the n ut cloc kwise will shor ten
the spring; counter -cloc kwise will lengthen the
spring .
4. Loc k the n ut into position b y tightening the
spring jam n ut ( Figure 65 ).
