2. Recheck knives/row clearance and readjust
rockshaft/wheels, as well as draft link length,
if necessary.
3. Shred a short distance, stop and check stub-
ble to insure knives are properly clearing rows
and satisfactory performance is obtained. If
necessary, reset rockshaft/wheels and draw-
bar’s underneath draft link.
4. If aftermarket or optional hydraulics are in-
stalled, insure cylinder stop collars, or inte-
gral trips, are EQUALIZED on 18’, 20 and 25’
units.
3 POINT HITCH HEIGHT ADJUSTMENT
Three point height adjustment differs from trailing
height adjustment because:
No shredder drawbar and underneath draft link ex-
ist.
The tractor’s 3 point POSITION CONTROL and
upper link length are involved.
Tractor lower links height above the ground may
vary because of differing wheel sizes. See FIELD
PREPARATION, page 13.
1. Set tractor 3 point hitch hydraulics in POSI-
TION CONTROL mode.
IMPORTANT: NEVER OPERATE SHREDDER
WITH TRACTOR 3 POINT HYDRAULICS IN
OTHER THAN POSITION CONTROL MODE.
FAILURE TO DO THIS CAN RESULT IN INAD-
VERTENT SHREDDER “PLOWING” INTO THE
GROUND.
2. Temporarily set position control stop to main-
tain lower links approximately parallel to the
ground.
3. Position unit astraddle rows and insure wheels
are centered in row middles before making
any adjustments. Rotate rockshaft/wheels un-
til knives clear rows by GREATER than 3”.
IMPORTANT: CHECK TRACTOR UPPER LINK
LENGTH WHEN ADJUSTING WHEELS TO IN-
SURE “LOST MOTION” LINKAGE DOES NOT
GO “SOLID”.
4. Readjust tractor’s position control down stop
until shredder is approximately level.
5. Shred a short distance, stop and check stub-
ble to insure knives are properly clearing rows
and satisfactory performance is obtained. If
necessary, reset rockshaft/wheels and trac-
tor’s position control stop.
6. Adjust 3 point upper link length to position
cross pin in “lost motion” slot approximately 1”
from rear of slot.
IMPORTANT: ALWAYS OPERATE CROSS PIN IN
“LOST MOTION” SLOT WITH APPROXIMATE-
LY 1” CLEARANCE FROM REAR OF SLOT. IF
THIS IS NOT MAINTAINED, DAMAGE CAN OC-
CUR FROM UPPER LINKAGE “BOTTOMING”.
STORAGE
CAUTION: DEATH OR SERIOUS INJURY
CAN RESULT. DISENGAGE PTO, STOP
TRACTOR ENGINE, SET BRAKES,
REMOVE KEY AND ALLOW EQUIPMENT TO
COME TO A COMPLETE STOP BEFORE:
CLEANING, UNCLOGGING, LUBRICATING, IN-
SPECTING, OR OTHERWISE SERVICING, ANY
PART OF THIS EQUIPMENT.
Do not store the shredder outside between sea-
sons of use. That lowers resale/trade in value.
The following will insure equipment is in top oper-
ating condition at start of next season.
1. Open end shields and thoroughly clean out
dirt and trash. Clean out any other trash hang-
ing on unit. Check drive shaft and gearbox
bearing seals for trash entanglement.
2. Back off backwrap belt idlers to relax tension
on “V” belts. Inspect belts for wear.
3. Clean debris from PTO ends and insure safe-
ty shield freely rotates.
4. Relube machine and check gearbox lube lev-
el.
5. Clean rust off exposed surfaces and repaint
any surface requiring it. Also check for any
loose hard-ware.
6. Inspect both rotor assemblies for lost, broken,
or worn out knives. Replace these as required.
Also, replace any other deteriorated parts, es-
pecially decals and reflectors.
