NOTE: Whenever possible, leave augers running while traveling from the loading/mixing area to
the feeding area. This will minimize packing of the feed mixture.
On trucks mounted mixers, this can be done by not pulling the speed control handle all the way to
the “OFF” position and leaving it a little forward of the “OFF” position.
On trailer mounted mixers, this can be done by finding the best gear that will give you the desired
ground speed you want, while at the same time allowing you to leave the PTO running at the slowest
speed possible with 2 speed gearbox in low speed.
Discharging Instructions
The discharge rate of your mixers ration is controlled by three items:
- the amount that the discharge door is opened
- auger speed
- conveyor speed.
The conveyor should be running any time that the discharge door is opened to dispense the load.
You may vary the speed of the discharge conveyor with the one-to-ten flow control. Adjustment of
discharge speed setting will allow an even discharge of your ration.
On truck mounted units, the truck engine should be operated between 1500 and 1800 RPM to provide
adequate hydraulic oil to operate the conveyor and door controls, and for the most effective mixer
operation.
After you have engaged the tractor PTO when starting to discharge a full load, the engine of the
tractor should be operating at 1800 RPM and the mixer should be in low gear. When 6,000 lbs. of
mix or less are in your mixer, shift two speed gear box on mixer into high speed for a quicker clean
out, (maintain 1800 RPM on tractor’s engine).
TWO SPEED SHIFTING PROCEDURE,
( TRAILER MOUNTS ONLY)
ALWAYS STOP THE PTO WHEN SHIFTING THE TWO-SPEED GEARBOX
The shift feature of this two-speed reducer is accomplished by sliding splines in and out of mesh.
For this reason the reducer must be shifted while in the static or non-rotating mode (PTO off ). An
isolator spring is incorporated in the design to act as a cushion should splines meet head to head in
the static mode. The spring allows the piston to complete its travel without overloading the spline
tips and also provides the acceleration necessary to engage the splines once slight rotation is
accomplished. For this reason the lower the PTO shaft acceleration or start up speed, the better the
chance for a completed shift will be.
•
To make a shift you should first lower the engine speed to low idle speed and
disengage the PTO shaft.
•
Activate the toggle switch in the cab of the tractor or shift the manual cable lever to
initiate a shift with the engine at low idle and PTO off.
•
Engage the PTO slowly and look for a complete shift.
If a ratcheting sound is heard, then a shift was not completed. No harm will be done to the
box because the spring controls the forces seen by the splines.
