3.5.1. Working Depth Adjustment - Cross
Cross units are designed for operation up to 15 cm with undercutters and up to 30 cm without or
with narrow coulters. Do not exceed these values.
Fig. 11: Working depth adjustment
• Perform hydraulic adjustment by pressurizing the cylinder (A) from the tractor cab, which
extends the cylinder. Then, put on the required number of stops (B) and pressurize the
cylinder (A) again to slide it back to the stops (B). Through this, you can raise or lower the
rear roller of the machine. Secure the cylinder (A) against dropping down with the lever (C).
• When adjusting the working depth with the cylinders, keep in mind the parallel position of
the machine frame during operation. Lower the machine correctly on the tractor three-point
linkage/hitch.
• If required, repeat the steps above several times to obtain the desired working depth.
•
After setting the working depth, you can begin adjustment of the disc harrow.
If the adjustment range does not match the actual field conditions, you can change it by varying the
cylinder length:
• Remove the nut and pull out the bolt [D] . Caution: the cylinder tip can be released freely,
endangering your health, so support or suspend it
• Extend the cylinder to its extreme position [A] by applying pressure to it
• Screw the cylinder head in or out, aligning the hole in it with the hole in the carriage
•
Secure the cylinder with the bolt and the nut
