Do not attach the machine to the
floor, let it unattached with all the feet laying

in order to absorb the equipment vibration.
Attaching the machine to the floor leads to a
warranty loss.

remove the drainage plug (1) located in the gearbox
mounting base.
Use 700 ml SAE 140 oil every change or add oil until

Blades sharpening

The TRAPP forage harvester leaves the factory with
tempered blades.
To sharpen them, remove the screws (C) which
attach the cutting blade (A) to the disk (D) as
indicated in Figure 14, and remove the cutting
blade. Use an appropriate tool or a manual file,
sharpen one cutting blade at a time and mount it in
the same place it was removed from so as not to
affect the disk balance.

Sharpen the blades if you notice that the cutting
edges are wearing out (blunt edges). Only sharpen
the blade side as indicated (fig. 13) by keeping the
same slant at all times. Always try to sharpen each
blade evenly so that to keep shaft assembly balance
and to avoid causing vibrations. Replace the blades
whenever an optimum sharpening no longer can be
achieved.
