Hitching to the tractor is done in the normal manner. Due to the oval shape of the drawbar
fastening pin holes, washers must be installed under the ring cotters.
The final hitching stages include connecting the hydraulic hoses and raising the support
leg. Lift the cultivator slightly off the ground. Turn off the tractor and engage the parking
brake.
Connect the hoses to a dual-function power take-off with non-locking lift and lower control
lever positions. If the valve has a floating position, switch the lever to this position to
facilitate hose connection.
Remove the pin from the cultivator’s support leg, lift the leg and lock it in the raised
position.
Observe extreme caution when working between the tractor and the
cultivator unit when adjusting the support leg and installing the hydraulic
hoses!
Adjust the levelness of the cultivator by adjusting the height bars of the tractor’s push bar
and drawbars. If the cultivator is to be used on very uneven terrain, set the tractor’s height
bars to a position which allows vertical free movement.
The lateral limiters of the drawbars can be set as either fixed or to allow some lateral
movement.
5. Cultivator adjustments
5.1 Setting the working depth
The cultivator’s working depth is set by adjusting the position of the discs in relation to
the cultivator frame and to the support wheels and press wheels at the rear of the frame.
The adjustment is performed by rotating the square shafts to which the discs are
attached using a hydraulic cylinder (see Figure 2).
