OVERLOAD PROTECTION
When shear bolt failure is detected, stop all operation and follow the EMERGENCY SHUTDOWN
PROCEDURE.
There are two types of driveline protection on the Top Shot. If the PTO Torque Limiting / Overrunning
Clutch disengages, reduce the tractor RPMs, and the clutch may re-engage. If it doesn’t re-engage, follow
the EMERGENCY SHUTDOWN PROCEDURE and check for a foreign object. Shear bolts are also used
to provide overload protection in two areas on the
Top Shot
. Follow the instructions below.
UNLOADING & SPREADING
Packed Material
To unload and spread packed material and prevent unnecessary stress on the drive line components,
observe the following guidelines:
1. Make sure the auger is completely lowered.
2. Engage the tractor PTO at as low an RPM as possible. Then, slowly bring the PTO up to the rated
RPM.
3. Raise the discharge gate until it is about 1/3 open.
4. Select the desired tractor gear and begin spreading. To achieve the desired coverage, adjust the
discharge gate and/or travel speed.
5. When spreading material which is susceptible to bridging, the auger should be cycled up and
down, frequently, to provide a more consistent feeding of material into the expeller.
NOTE: Do NOT exceed the rated 540 or 1000 RPM operating speed of your particular model of
Top Shot .
OPERATION
-22-
Expeller Drive
The discharge expeller sprocket has two ¼” x 1-1/2” grade 8
shear bolts with locknuts. Additional shear bolts are stored on
the expeller front bearing mount.
The following are probable causes for discharge expeller shear
bolt failure:
1. PTO is being engaged while RPMs are too high.
2. A foreign object is present in the expeller.
3. Overfeeding of the expeller due to improper discharge
gate adjustment.
4. Gate is being raised when spreading liquid material,
before expeller is up to operating speed.
Auger Jackshaft
The auger drive sprocket is secured to the auger
jackshaft hub with two 5/16” x 1-1/2” grade 8 shear
bolts and locknuts. Additional shear bolts are stored
in the chain tensioner bracket.
