Unhitching a seed drill from the cultivator
•
Park the seed drill on a level base and secure it in place. When parking, raise the
drawbar high enough to enable the cultivator to be driven away from beneath it.
•
Using the tractor’s hydraulics, release the pressure from the seed drill’s lifting
cylinders. If the machine has a hydraulic drawbar, leave it at a suitable height
o
If the seed drill’s drawbar is single-functional, lock the cylinder using the
cylinder cock
•
Disconnect the hydraulic hoses and lighting and electronics cables
•
Raise the cultivator so that the draw ring of the seed drill’s drawbar does not force
up the lock pin of the cultivator’s draw pin
•
Remove the lock pin’s locking bar and lift up the pin
•
Lower the cultivator and drive it out from beneath the drawbar
•
Pull down the lock pin and fasten the locking bar in place
Observe extreme caution when hitching and unhitching trailed machine
units from the cultivator’s draw pin!
Never go beneath the structures raised on hydraulics. Use mechanical
supports if necessary.
When working between the tractor and the cultivator, the tractor must be
parked with the hand brake engaged and the engine off.
Make sure that there are no unauthorised people in the danger area of the
machine or in the tractor cab during hitching and unhitching!
Check the hitch regularly. It is strictly forbidden to operate the machine
with a non-secure hitch. Worn or damaged parts must be replaced
immediately.
6.4
Working load limits of the draw pin
The draw pin is intended for towing Tume seed drills and fertilizer seed drills that are
equipped with a multi-purpose drawbar.
Working load limits at the end of the seed drill drawbar:
Tensile load backwards at a 0–45 degree lateral angle:
100 kN
Tensile load forwards at a 0–45 degree lateral angle:
50 kN
Downward load:
50 kN
Upward load:
1 kN
Exceeding the above-mentioned working load limits is hazardous and
strictly forbidden.
