Restrictor Blades
The restrictor blades are located at
the front-left and rear-right corners of
the mixing chamber walls. Each
restrictor blade comes complete with
an adjustment pin that locks the
blade into position. When
completely inserted, the restrictor
blades will slow a large bale or
mixed feed from moving around the
outside of the mixing chamber, thus
allowing the knives to perform
aggressive cutting. The restrictor
blades may be retracted to the out
position to lessen the cutting action.
The best position of the restrictor
blade is based on user preference.
Important: Position the Restrictor Blades in the ‘IN’ (retracted) position during
transportation of the machine to reduce overall width.
ATTACHING/UNHOOKING
The machine should always be parked on a level, dry area that is free of debris and foreign
objects.
Follow this procedure when attaching:
1. Clear the area of bystanders and remove foreign objects from the machine and working
area.
2. Make sure there is enough room to back the tractor up to the hitch point.
3. Start the tractor and slowly back it up to the hitch point.
4. Stop the tractor engine, place all controls in neutral, set park brake, and remove ignition
key before dismounting.
5. Adjust the length of the drawbar to give the appropriate dimension between the PTO
shaft and drawbar pin hole. (Refer to Tractor Operator’s Manual).
6. Use the clevis on the hitch to level the machine.
7. Use the jack to raise or lower the hitch pole to allign with the drawbar.
8. Install the drawbar pin with provisions for a mechanical retainer such as a ‘Klik’ pin.
Install the retainer.
9. Attach safety chain between the machine and the tractor drawbar cage.
10. Connect the PTO shaft:
•
Check that the PTO driveline telescopes easily and that the shield rotates freely.
