Then thread it back across the front of the center
sheave in the top groove.
Figure 6.
Proper Twist: The belt then follows with a 3/4 twist
back under the left V-idler, up over the drive sheave
and back down under the right idler pulley. This will
leave a 1/4 twist in the section of the belt extending
from the right V-idler to lower groove of the center
mower sheave.
Adjust the mower to proper cutting height. The front of
the mower should be slightly lower than the rear for the
best cutting and least power requirement.
Idler Adjustment: Make minor belt adjustment with
idlers but keep left idler about 1" above being in line
with the groove in which the belt runs on the center
sheave of the mower and right idler about 1" below.
Move mower fore and aft for major adjustments. On
L306K210, K260, S & F10, use belt takeup idlers on
mower deck for major adjustment.
After belts are properly aligned, lock sheave (32) an d
bushing (31) in place. Torque bolt to 12 lbs-ft alternat-
ing back and forth at least six times.
NOTE: Make major belt adjustment by sliding mower
fore and aft, using the five holes in arms as required.
Make minor adjustments with idlers, but keep left V-
idler about 1" above being in line with groove in which
belt runs in center mower sheave and right V-idler
about 1" below.
After mower is completely assembled and at the proper
cutting height, tighten the center rear pivot pin secure ly.
Lift Attachment (See page 14)
Bolt lift assembly (14, 15, 83, and 85) to right hydraulic
arm of tractor with two 5/8 x 1-3/4 bolts, nuts, and lock
washers.
Attach one 33 link chain (11) through keyhole of each
rear lift lug on mower frame. Install a plastic caplug (8)
into keyhole below chain. Attach upper end of 33 link
chain (11) to eye bolts (85). Raise mower slightly and
adjust chains so mower will raise level and will not hit
tires, etc., when fully raised.
Shielding
Bolt V-belt shield attachment bracket (26, page 16) to
the tractor transmission housing with two 1/2 x 1" bolts
and lock washers.
Place the V-belt shield (27, page 16) over the rear drive
and secure with flat washers and wing nuts.
