STARTING UP AND BREAK IN
Always engage the tractor’s power-take-off (PTO) at low speed (engine speed at idle) in order to prevent the
eventual breaking of the safety bolt on the transmission line. The harvester has a high inertia and applies a
high load on the PTO when starting. Have the tractor PTO clutch calibrated by the tractor dealer in cases of
hard starts.
Before going to the field, check that all control box functions are working properly.
WARNING: Make sure all harvester guards and shields are properly in place before starting up the
tractor.
When starting up a new harvester, run the machine at mid PTO speed for about 5 minutes in stationary
position. Then run at full speed for at least 3 minutes. If no issues or bearing overheating is detected, the
harvester is ready for operation.
KNIVES AND SHEARBAR
If the Forage Harvester is used in normal conditions (on a dry field, 5 to 6 hours a day), we recommend
grinding the knives once a day. However, if work is performed on an excessively muddy or sandy terrain, or
with highly abrasive crop, two daily grindings are recommended. Refer to the KNIVE SHARPENING section on
page 52.
The cutting head is as important as the shearbar and vice versa when a perfect cut is desired. Proper
maintenance and preparation of these two components will result in the following:
Evenly cut silage
Less required power
Less downtime because of mechanical breakdowns
NOTE: The shear bar adjustment must always be done following one of these operations:
Knife grinding
Whenever knives must be moved forward
Knives have been replaced
Shearbar has been replaced or flipped over
SHEARBAR DESIGN
Refer to Figure 61 for the following explanations.
The Dion shearbar contains to notches on each side in which specifically designed bolts sit to adjust
the shearbar parallel to the knife drum.
The shearbar clearance adjustment (item 3) guides the bar laterally. Tightening it pushes the bar
along the notched ramps, moving the bar towards the knives (see arrow).
