4. Measure the right blade at the B location, from
a lev el surface to the cutting edg e of the blade
tip ( Figure 62 ).
5. R ecord this measurement.
6. T he mo w er blade should be a 1/4 to 3/8 inc h

position B ( Figure 62 ). 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

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)
for 52 inc h mo w er dec ks and 10-1/2 inc hes
(26.7 cm) for 60 inc h mo w er dec ks ( Figure 63 ).
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 63 ).
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
