Figure 6. Standard tow-bar assembly.
The towing device is attached to the machine frame side brackets.
The push-bar (hydraulic or mechanical)
in the picture is connected to the upper holes of the bracket on the front of the hopper.
Hydraulic lines and electrical wires are pulled through the tow-bar and attached to hanging hooks on the tow-
bar. The hydraulic push-bar (optional) tube is connected to its own, one-way hydraulic valve.
Once the hydraulic line layout is completed, these should be fixed in position by bending the line supports
so that the lines remain in place.
Adjust the push-bar working dimension so that the machine is horizontal when calculated in terms of working
depth and attached to the tow-point at working height (tractor tow-hook, tow-bars in working position,
intermediate cultivator towing point, etc.). Ensure that the push-bar cylinder is in its retracted position when
carrying out this adjustment. Fine tuning of the towing device can be performed in the field, under sowing
conditions.
