Cutter-Mixer-Feeder will vary greatly with the various feeds
and climatic conditions. In most instances, “trial and error” is the best method of setting the
machine up for a particular commodity to obtain maximum performance. To prevent over-
cutting of feed, we suggest starting with the restrictor blades in the out position, and then
adjusting to obtain the desired coarseness of the mix. The bulkiest and lightest commodities
should be added first. Once these commodities are partially cut and broken apart, others
can be added. Additional cutting will take place during mixing, so be careful not to over cut.
The order in which the secondary ingredients are added is up to the operator. The type of
mix required varies from one operation to the other, and therefore, mixing times and
procedures will vary as well.
It is recommended that commodities are added to the mixing chamber while the augers are
turning for maximum mix efficiency. Operate the PTO driveline at 1000 RPM. On standard
driveline units, the augers will rotate at a speed of 41 RPM. On units equipped with the 2-
speed Transmission option, the augers will rotate at a speed of 41 RPM in ‘High’ Gear, and
32 RPM in ‘Low’ Gear. Starting the augers from a standstill with a full load in the mixing
chamber places additional stress on the machine. Even though it is designed to handle this
stress, repetitive startups under load may affect the service life of the machine. If however,
due to circumstances, it is required to restart the machine while loaded, retract the restrictor
blades all the way in order to decrease starting torque as much as possible.
Warning: While loading the machine, be certain that no bucket or loading device comes
into contact with the rotating augers inside the mixing chamber. This may
cause serious damage to the mixer and/or loader, and may cause injury or
death to the operator.
Warning: Never load an unhitched machine. The machine is designed to be loaded only
when properly hitched to a suitable tractor. Improper loading can cause loss of
control, severe injury, or death.
Warning:
A loaded machine (machine and payload) may weigh as much as 27,400 kg
(60,400 lbs.). An operator must use his own discretion when negotiating rough
and uneven terrain. Improper operation of the loaded machine can cause loss
of control, severe injury, or death.
Danger:
Never enter the mixing chamber or go on the conveyor unless all controls are in
neutral, engine stopped, park brake set, ignition key removed and all moving
parts have stopped. Failure to follow these safety precautions can result in
serious injury or death.
Important: Always remove twine, string, and wrapping material from bales and/or other
commodities from the ground that will be loaded into the mixing chamber.
Failure to follow these requirements can cause damage to the machine.
