First put belt on the bottom groove, right hand side of
the center sheave. Then thread it to left, around the left
hand sheave.
Figure 6.
Bring the belt back across the center sheave in the
center groove over to the right outside sheave.
Figure 7.
Then thread it back across the front of the center
sheave in the top groove.
Figure 8.
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 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 of 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, and F10, use belt takeup idlers on
mower deck for major adjustment.
Make major adjustments by sliding mower fore and aft,
using six holes in channel arms as required. Using a
new belt, the push arms normally will be attached to
the idler frame with mower sitting in second hole from
front end of channels.
Minor adjustments are made up and down with idler
pulleys. After belt has been run for 15 to 20 minutes,
belts should be re-tightened. Run very tight.
