Refer to Figure 19
Check all chain idlers at beginning of each season
for proper adjustment. Check that each idler is
taking up excess chain slack. The access door is
located on the top side of the gage wheel arm
near the pivot end.
After first 100 hours of use and at beginning of
each season, readjust idler sprocket in left wheel
arm. To access idlers, remove access door.
Refer to Figure 20
To adjust idler sprocket, move top idler sprocket
(1) down into chain by loosening jam nut and
screwing in adjustment stud (2). Retighten jam
nut to maintain idler position.
NOTE: Do not overtighten chains. Overtightening
chains will cause excess wear on idlers and drive
components. Be sure chain is installed with the
chain connector link retainer towards the center-
line and the clip opening (split end) faces the op-
posite way of the chain travel.
