HYDRAULIC SYSTEM
Hydraulic Pump Sheave Alignment
The hydraulic pump drive and driven sheaves must be maintained in correct alignment and be tightly
secured at all times.
Hydraulic Pump Belt Tension
Overload protection for the hydraulic pump is provided by a self-adjusting spring tightener that requires
no adjustment. The idler pulley must be properly positioned to keep the belt aligned with the sheaves.
Hydraulic Reservoir
The oil filter should be replaced once a year or every 75 hours of operation, whichever comes first. The
oil should be drained and replaced every two years or every 150 hours of operation, whichever comes
first. Keep oil filled to proper level.
OVERLOAD PROTECTION
Gearbox/Mixing Auger Shear Bolt
The mixer is furnished with a shear bolt protecting the gearbox and mixing auger. When the shear bolt
fails, the mixing auger will stop turning. This may be a result of an overfull tank, the lid did not release,
an obstruction, or some other issue. Shut down the tractor and mixer, disconnect the PTO, and proceed
as follows:
1. Clean any material out of the intake area possible with a scoop or shop vac..
2. Check for a broken chain, drive sprocket or driven sprocket or for sheared keys which hold the
sprockets. Replace any damaged parts.
3. Replace the with the recommended shear bolt.
4. If the items in steps above are not at fault, remove the gearbox drive chain and attempt to rotate
the gearbox input shaft. If the input shaft turns freely, internal transmission component failure is
probable. Remove the gearbox and take it to your nearest dealer for repair.
After the cause of the plugging has been corrected, reinstall all components, guards and shields before
resuming operation.
IMPORTANT: Stop mixer operation when the shear bolt fails.
SERVICE
ENGAGING PIN
The pin used to engage and disengage the mill/blower drive sheave should
be checked periodically for excessive wear or improper seating. Excessive
wear on the pin or the hole in the hub that the pin engages could result in
the pin accidentally disengaging in the middle of mill and blower operation.
Both components should be replaced if worn.
IMPORTANT: Do not start the PTO until the pin is positively engaged.
Using the PTO to engage the pin will cause premature pin failure.
