7 Operation
The simplicity of the KEENAN Mixer Wagon design is reflected in its low power requirement.
The power required varies, depending on the mix used, the dry matter, and the amount of
chopping required.
If a tractor is at its limit during mixing, this will translate into extra strain on moving parts as
there will be surges in power as the engine recovers during certain periods of the mix.
A tractor that has sufficient power will provide a much smoother drive to the mixer wagon during
all stages of operation.
7.1 Set-up
1. Ensure the machine is level when hitched up. If the machine is un-level, this can be
corrected by adjusting the hitch height. The hitch height on the KEENAN MechFiber
mixer wagon provides a certain level of adjustment from the manufactured height.
2. The PTO shaft should be attached with the shear bolt end coupled to the machine.
Make sure that the PTO guard is in good condition and well secured.
3. Connect the hydraulic hoses (see table 1) from the machine to double- and single-acting
spool valves on the tractor, as appropriate.
4. Examine the mixing chamber to ensure that:
• All blade covers have been removed.
• All spare parts and foreign objects have been removed.
• No damage has occurred during transport.
5. Check the weigh box and ensure the power lead from the weighing system is either
connected to the tractor battery via a direct fused line, seven-pin plug or to a 12-volt
battery located in the side box of the feeder. To zero the weigh box press and hold the
‘zero’ and ‘minus’ keys together and hold until ‘end’ appears on the screen then release
the buttons. If the power is supplied through a seven-pin lights connection, the tractor
lights will need to be switched on to provide power to the weigh box. If you stand on the
ladder, at the rear of the machine, you can check the reading on the weigh box against
your known weight. This may require assistance.
6. With the tractor running, check that the VFC-door opens fully and closes completely.
Similarly, check the movement of the feed out tray. Engage the PTO and check the
turning of the paddles. The initial turning of the paddle rubbers against the side of the
KEENAN MechFiber mixer wagon will generate noise, but this will decrease as the
paddle rubbers become more pliable.
CAUTION:
Do not operate the PTO in “ground speed” mode. Reversing the drive on your machine
will cause serious damage.
