PACKER SPRING SETTINGS
TO MAINTAIN PROPER REAR MACHINE DEPTH THE SPRING ON EACH PACKER ASSEMBLY MUST BE ADJUSTED TO BALANCE THE
WEIGHT OF THE MACHINE AND ALLOW PROPER RELIEF OF THE PACKER WHEELS WHEN ENCOUNTERING UNEVEN TERRAIN.
ONCE THE PACKER PIVOTS HAVE BEEN PROPERLY ADJUSTED AS NOTED ABOVE THE SPRING CAN BE ADDED AND THE SPRING
NUTS ADJUSTED. THIS SHOULD BE DONE WHEN THE UNIT IS COMPLETELY ASSEMBLED AND LEVELLED ON A FLAT SURFACE
PRIOR TO GOING TO THE FIELD. LOWER THE UNIT SO THE SHANKS OR INJECTORS JUST CLEAR THE GROUND.
ALL SPRINGS SHOULD BE SET TO MAINTAIN CONTACT BETWEEN THE SPRING PLATE AND THE FRAME STOP ON EACH PACKER
PIVOT. THIS SETTING IS DEPENDENT ON THE LOAD THAT IS SEEN BE EACH PACKER. SINCE THERE IS MORE WEIGHT ON MOST
OF THE MAIN FRAME PACKERS THE SPRING SETTING (SS) WILL BE GREATER THAN REQUIRED ON THE OUTER WINGS. SET THE
SPRING DISTANCE (SS) ON ALL SPRINGS TO MAINTAIN THE SPRING PLATE TO FRAME STOP CONTACT WITH THE WEIGHT OF
THE UNIT. WHEN PROPERLY SET THE PACKERS SHOULD NOT MOVE EXCESSIVELY UNLESS THE PACKER WHEELS ENCOUNTER
UNEVEN GROUND OR AND OBSTRUCTION.
1) WITH THE MAIN FRAME LEVEL TIGHTEN THE SPRING
BOLT TO A (SS) DISTANCE OF APPROXIMATELY 3/8"-1/2"
ON ALL THE MAIN FRAME PACKERS.
2) TIGHTEN THE PACKER SPRINGS ON THE INNER
PORTION OF THE INNER WINGS TO A (SS) DISTANCE OF
3/8"-1/2" WITH THE REMAINING WING PACKER SPRINGS
TO A LESSER DISTANCE.
3) DEPENDING ON THE WEIGHT AND SIZE OF THE UNIT
TIGHTEN THE REMAINING PACKER SPRINGS ON THE
OUTER WINGS TO A 1/4" TO 3/8" DIMENSION.
4) CHECK TO ENSURE THAT THE SPRING PLATE TO
FRAME STOP CONTACT IS MAINTAINED TO ENSURE THAT
ALL PACKERS ARE SET TO THE SAME DEPTH.
5) PROCEED TO COMPLETING THE FIELD SETTINGS
AND CHECK TO SEE THAT THE STOP CONTACT IS
MAINTAINED AS THE UNIT MOVES THROUGH THE FIELD.
IF THE PACKER PIVOT ARMS ARE MOVING EXCESSIVELY
DUE TO NORMAL LOADING, NOT OBSTRUCTIONS,
TIGHTEN THE SPRING NUTS. TIGHTEN SPRINGS ONLY
TO THE POINT OF MAINTAINING SPRING PLATE TO
FRAME STOP CONTACT WHILE OPERATING. EXCESS
SPRING PRESSURE WILL RESTRICT RELIEF WHEN

PACKER ASSEMBLY/SETTING INFORMATION
ONCE EACH PACKER ASSEMBLY HAS BEEN COMPLETED WITHOUT
MOUNTING THE SPRING, IT IS CRITICAL TO PROPERLY SET THE
TIGHTNESS OF THE PACKER ADJUST POINTS INDICATED.
THE
SPRING LOADED PACKER ASSEMBLIES WILL NOT FUNCTION
PROPERLY IF THE NOTED POINTS ARE OVER TIGHTENED. BOTH
THE SPRING PIVOT ARMS AND PACKER WALKERS MUST ROTATE
FREELY.
TIGHTEN THE UPPER AND LOWER MAIN PIVOT BOLTS BY
ADJUSTING THE INNER JAM NUT. CHECK TO ENSURE THE ARMS
AND WALKER ARE FREE TO PIVOT. HOLD THE INNER JAM NUT WITH
A WRENCH AND LOCK WITH THE OUTER JAM NUT.
DO NOT USE AN
AIR WRENCH TO TIGHTEN ANY OF THE PACKER ADJUST POINTS.
SPRING PIVOT ARMS
PACKER WALKER
IF THE PACKER ADJUST POINTS ARE TIGHT THE SPRING WILL NOT
RETURN THE SPRING ARMS TO THE CORRECT POINT AND THE
DEPTH CONTROL AND PACKING OF THE REAR OF THE UNIT WILL BE
INCONSISTENT. WITH THE PACKER ARMS AND WALKERS ABLE TO
ROTATE AND THE SPRINGS SET AS NOTED BELOW THE PACKERS
SHOULD CARRY THE REAR OF THE UNIT AT A CONSISTENT
DEPTH AND ALLOW THE SPRING LOADED ARMS TO PIVOT WHEN
OBSTACLES ARE ENCOUNTERED
