Retry the shift sequence following the instructions above maintaining a low engine speed and
insuring PTO is off. When the shift is completed then increase the engine speed until the
desired speed is reached.
TWO SPEED SHIFTING,
(TRUCK MOUNTED MIXER AND STATIONARY MIXER)
Your Kirby truck mount / stationary hydraulic drive mixer has a two speed hydraulic motor coupled
to each of the planetary gearbox drive of your mixing augers.
The speed of the auger is determined by two factors, one is rpm of the truck and the other is pressure
required by the hydraulic system to keep the augers turning.
Once you have discharged the load to a weight that produces less than 3,125psi in the hydraulic
circuit the augers will automatically shift back to high speed to assist with a faster clean-out.
If your truck is mixing at a RPM of 1800 rpm, your augers will be turning approximately 40 RPM.
This is with an empty load and minimum pressure needed to turn the augers. If you were to load
your hay first into the mixer the augers would be turning at approximately 40 RPM for faster cutting
action. Once your load reaches a predetermined pressure (3,125psi) the augers will shift down to
half the speed, (approximately 20 RPM). The above pressure is the pressure that the hydraulic circuit
experiences while in operation. This will reduce your power requirements and still give you an
excellent mix.
