Engaging the drill

Figure 3.5
The drill must always be moving when lowered to ground. Keep the hydraulic lever in the pres-
surised piston, i.e., lowering position, until the bout marker has been completely folded out. Using
the Control Station, verify that tramlining has been advanced and that the correct lamp goes out
and the correct one lights and that the alternate during subsequent raising.
When driving, usually low-lift and auto advancing should have been selected.
If a seed coulter becomes blocked, do not go under machine unless it has been properly secured
with the yellow locking devices. See "2.27 Locking the lifting rams during service" on page 59.

Tramlining

The preparation of tramlines and setting of the Control Station are described in "2.22.2 Func-
tions" on page 45 and "2.22.8 Tramline options" on page 54.
During sowing, the most important thing to remember about tramlining is to shut off Autostep be-
fore doing anything other than normal sowing or turning in headlands between bouts.
So, remember to switch Autostep off before raising the drill to pass an obstruction.
When it is time to refill the seed hopper or take a break, the drill should be raised from the last
furrow, then wait for approx. 10 seconds. Switch off auto advancing. There is no need to switch
off auto advancing in case no additional lifting is required during the pause. When continuing
drilling, switch on auto advancing before the drill is raised the first time.

Bout markers

Setting of the bout markers using the Control Station is explained in "2.22.2 Functions" on page
45. See also "3.7 Obstructions" on page 69 and "3.8 Turning with Low lift" on page 69.
Once a reliable setting for the bout markers has been found, it is a good idea to mark this position
using e.g. a centre punch. Check occasionally that the marker tines are securely tightened.
The final tillage operation before sowing should preferably not be done in exactly the same direc-
tion as that intended for sowing, but at a slight angle to it.
