MILL/BLOWER DRIVE BELT SLIPPAGE
Overload protection for the mill and blower components is provided
by an 8 "A" section drive belt, which connects the mill/blower
driven sheave to the drive sheave. The mill and blower will gradually
slow down without much reduction in tractor PTO speed if plugging
develops from mill/blower drive belt slippage, and stop turning the
mill/blower drive shaft if plugging or breakdown occurs in the mill
or blower areas. Follow steps 1 through 5 from the previous page
to remove the plugging. After the plugging has been
the tractor off, disengage the PTO, and adjust the drive belt tension
to the proper tension (see Adjustment Chapter). Restart the tractor
and PTO, bring the mill cylinder up to proper operating speed and
resume grinding.
IMPORTANT: Stop mixer operation if drive belt slipping is detected.
MAIN SHEAR BOLT
Blockage in the mixer may cause the tractor to stall. Shut down the tractor and mixer, disconnect the
PTO, and proceed as follows:
1. Open the mill screen cover and clean material out of the mill/cylinder and transfer auger area.
2. Check the auger/transmission shear bolt to determine if it
has sheared. Rotate the mill drive sheave by hand to turn the
sprocket, shaft and transfer auger. If the shaft does not turn,
follow the shear bolt replacement procedures according to
the Service Chapter in this manual.
3. After the shear bolt has been replaced, attempt to rotate the
entire assembly. If rotation, in either direction, is not possible,
proceed to step 4. If the sprockets and transfer auger turn but
the mixing auger does not turn, proceed to step 5.
4. Check for a broken chain, drive sprocket or driven sprocket or for sheared keys which hold the
sprockets. Replace any damaged parts.
5. If the items in step 4 are not at fault, remove the transmission drive chain and attempt to rotate the
transmission input shaft. If the input shaft turns freely, internal transmission component failure is
probable. Remove the transmission and take it to your nearest dealer for repair.
After the cause of the plugging has been corrected, restore all components, guards and shields before
resuming operation according to the Service Chapter in this manual.
