Machine Description
Range of Application
The Sub - Tiller is a sub -soiler for soil loosening from 0 cm to 60 cm depth. The work is preformed eith er
before seeding (min. tillage) or after harvest where a loosening of the tramlines in the field is desirable in
order to discourage structure damages. Infinitely variable tine spacing, depending on the actual working
task. The Sub - Tiller is ideal for all soil types and a V - profile roller is recommendable for moist and sticky
soil types while a square tube roller is recommendable for lighter soil types. The Sub- Tiller can be
mounted with HE -VA Multi-Seeder which opens up the possibility of till-seeding of rape or crops for
green manure.
The Sub - Tiller is mounted in the tractor s three - point suspension , and the hydraulic depth control via the
pack er roller is controlled by the hydraulic system of the tractor. In order to achieve optimum control you
have to be aware of the tractor wheels, und under certain circumstances a mounting of twin wheels is
recommendable.

Hydraulic automatic re lease system .
1. Before each season it has to be controlled, that the gas
pressure in the accumulator ( P os.1) is 90 bars. This
requires special tool s and can only be preformed by an
authorized dealer .
2. Before the start - up of the machine the hydraulic pressure in
the closed hydraulic stone protection system has to be
controlled on the machine s pressure gauge ( P os. 2) . The
pressure has to be approx. 120 bar . It can be adjusted after the
conditions.
3. IMPORTANT the hydrauli c pressure is to be controlled
continuously and must never be under 190 bar .
4. If there is a need to adjust the working pressure, follow the
below instructions :
a. Mount the quick coupling of the hydraulic hose (P os.
3) in the tractor s oil outlet .
b. Turn on t he ball valve ( P os. 4) , and the w orking
pressure can now be adjusted up or down with the
tractor s oil outlet .
c. When the desired pressure is achieved, turn off the ball
valve again (P os. 4) , and the tractor s hydraulic system
is relieved before the quick coupling ( P os. 3) is
dismounted and placed in the parking device of the
machine .
5. During the operation of the machine the tine is swinging
automatically to the rear if it meets an obstacle . In normal
circumstances the tine will automatically return to the working
position again after having passed the obstacle. At extreme
obstacles and/or soil conditions it might be necessary to stop
and eventually lift the machine from the soil. It is
important that no persons are near to the machine as the tine is
returning to the working p osition with high speed and might
throw with soil and stones.

After 10 hours of operation, retighten the machine. Check hydraulic hoses, fittings and cylinders
for leaks and retighten .
Further check on a regular basi s that all bolts are tightened .
Before the winter storage, wash and lubricate the machine. If you use high-pressure cleaner, do
not spray directly on the ball bearings. After the washing, you may spray the machine with oil.
Lubrication
For lubricati on, maintenance and repair, lower the Sub - Tiller , put the brakes of the tractor on and stop the
motor.
The 2.5 4.0 m Sub - Tiller (rigid) have f ive lubricating points, the 4.0 m 5.0 m Sub- Tiller (hydr.) have
20 lubricating points. All Sub - Tiller s shall be lubricated after every 30 working hours as well as after the
cleaning in order to press out any water and dirt. The lubricating points on the rigid machines are located
where the bar is mounted on the frame as well as at ball bearings and cylinders.
On the hydraulic model s there are further lubricating points, where the side sections are hinged on the
middle section and at the locking mechanism of the side sections on the middle section .
Moreover, the machines with hydraulic automatic release system have 2 lubricating points per tine which
are to be lubricated after 10 hours of operation .
Attention !
Important !
However , the double -sealed ball bearings in the roller
should only by lubricated ev ery 20 working hours and by
1-2 strokes so that the sealing rings are not pressed out.
Oil, type H ydro Texaco HD32 has
been filled in the hydraulic system.
