Shear Bolt Replacement
To replace the shearbolt on the litter
windrower, turn off the tractor and clear
the augers of any obstructions that may
have caused the shearbolt to shear. Re-
move the 5/16 capscrew holding down
the jackshaft shield. The shield can then
be flipped up out of the way exposing the
shear plates. Spin the augers until the
bolt hole in the first shear plate on the
chain side of the shaft aligns with the bolt
hole in the second shear plate on the
gearbox side of the shaft. Place a 5/16” x
2” grade 8 capscrew into the aligned bolt
Timing of the Augers
The augers on the Litter Windrower have been timed at the factory. Should the augers get out
of time there will be interference resulting in bent flighting and other damage to the machine.
If the augers jump time, shut off the tractor immediately. Remove the chain cover and inspect
the bottom chain and lower sprockets for wear and damage. To re-time the augers to their
original positions, with the bottom chain removed, spin the top auger until the end of the flight-
ing closest to the chains points towards the ground. Hold in place and spin the bottom auger
until the end of the flighting closest to the chains also points towards the ground. Reinstall
bottom chain while keeping the tension side tight. Once the chain is installed and tightened,
check the direction of the flighting ends to make sure they still point in the same direction.
holes and through both plates. Secure in place with a 5/16 locknut. Note: A replacement shear-
bolt is placed in the owner’s manual canister at the factory.
