KKIFi: POINT 1>OS1TION (Pitch Angle)
The pitch of the sicVle bar (E) can bo adjusted
by loosening bolts (G) and two set screws In
tie rod (P), ^ With sickle knife cover in
place; raise mower to vertical position and
push forward to Increase downward pitch of
cutter fingers. For normal cutting, the sickle
bar (E) should be positioned with a downward
pilch of approximately 1/4** from carriage
plate (A) as shown (Fig. 7). It may be neces¬
sary to increase downward pitch of shear
fingers when cutting extremely heavy, tangled,
or matted grass* or If green undergrowth Is
intermingled heavily with dry grass and weeds
from previous seasons. After desired setting
Is reached, lower mower bar to ground. Re-
tlghtcn bolts (G) in breakaway housing and set
screws in tie rod (P).
Note: Mis-alignmenl of pitman drive belt
may be noticed, however special grooved pul¬
leys allow for this to compensate for pulleys
position changes when sotting load and pitch.
To insUill Pitman drive l)eli. open safety
break-back release, manually, and slide I>eU
over carriage pipe. InsbiU belt (S) on jack-
shaft pulley (U) ami Pitman I^lley (T). Push
sickle bar hack into operating position
SETTING LEAD OF MOWER BAR
(Fig. 8) Improper lea<l adjustment of sickle
bar assembly will create excessive side draft
on tractor and poor cutting action* as well as
possibly plugging sickle knife. Outer end of
sickle bar at (1) should lead Inner end (2)
by two inches as Illustrated In (Fig. 8). To
adjust lead, loosen three vertical bolts (C)
in plate (A) and two sot screws in lie rod (P)
(Fig. 9). Adjust cutter bar (E) to lead sotting
as illustrated In (Fig. 8), by pushing outer end
of bar forward. Slots in carriage plate (A)
will adjust accordingly to allow for change
in lead setting. (Fig. 9). When proper setting
is obtained tighten vertical bolts (C) and two
set screws in tie rod (P). IMPORT .ANT: Pro¬
per V-belt tension will allow approximately
1/2** deflection of V-belt when applying firm
finger pressure midway between pulleys (Fig.
9a). (^e adjustment of drive belt, page €).
