
The condition of the shearbar is just as important as the knives for a high-quality cut. This bar
features two cutting faces covered with tungsten (item 4). When the edge loses its sharpness, it can
be rotated around to use the other edge.
NOTE: For daily adjustments, after sharpening the knives for example, only the side adjustment (item 3) is
used.

WARNING: Stop the PTO and turn off the tractor engine before servicing the harvester.

Refer to Figure 62 for the following steps.
1. Open the sharpening door (item 1) by rotating clockwise the door rod with the 3/4” wrench.
2. Start the tractor engine and engage the PTO. Set the speed to approximately half the operating
speed (~600 rpm for « 1000-1000 » models and 750 rpm for « 1000-800 » or « 540-800 » models.
3. Proceed to sharpening by pushing and pulling the stone carriage at constant speed along the full
width of the cutterhead using the handle (item 2). A full stroke should last less than 5 seconds to
obtain a smooth grinding.
4. Lower the stone by pulling the carriage completely to the end of the stroke, close to the operator.
The stone will lower slightly for every click.
