damages.
Machine description
Range of Application
Combi-Tiller is a sub-soiler developed for working solo or combined with a stubble implement or a
drill unit. The Combi-Tiller MKII lifts the soil to break hard stratum of earth/plough pan together with
an oxidation of the soil –without bringing large unwanted clods to the surface. The Combi-Tiller has a
working depth from -50 mm down to 300 mm. The tine points have 200 mm wing shares lifting and
loosening the soil in the chosen working depth. The Combi-Tiller is ideal for all soil types.
The Combi-Tiller is available for mounting directly in the three-point suspension of the tractor with
the possibility to be combined with an implement mounted in the sub-soiler’s linkage. Alternatively,
the Combi-Tiller is available in a combination with a trailed HE-VA Disc-Roller.
In order to achieve optimum control, you have to be aware of the tractor’s wheels, and in some soil
conditions a mounting of twin wheels is recommended.
The machine is delivered in transport position from the factory.

Hydraulic automatic release system
Before each season it has to be controlled, that the gas pressure in the accumulator
(Pos.1) is 90 bars. This requires special tools and can only be performed by an
authorized dealer.
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 (Pos. 2). The
pressure has to be minimum 100 bar and must not exceed 160 bar.
IMPORTANT –the hydraulic pressure is to be controlled continuously and must never be under 100
bar. If there is a need to adjust the working pressure, follow the below instructions:
Mount the quick coupling of the hydraulic hose (Pos. 3) in the tractor’s oil outlet.
Turn on the ball valve (Pos. 4), and the working pressure can now be adjusted up or down
with the tractor’s oil outlet.
When the desired pressure is achieved, turn off the ball valve again (Pos. 4), and the
tractor’s hydraulic system is relieved before the quick coupling (Pos. 3) is dismounted
and placed in the parking device of the machine.
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 position with high speed and might throw with soil and stones.
Replacement of wearing point
Before working with the machine’s wearing points, the machine is to be fastened.
This can be performed by trestles under the main frame.
Dismount M16x65 mm bolt (Pos. 1) by means of 2 pcs. 24 mm spanners. The
wearing point might fall off, when the bolt is removed –take care of foot and leg
injuries.
Dismount the wearing point by pushing it forward. This might be difficult due to
entrance of soil, and it might be a good idea to use a hammer.
Mount the new wearing point, item no. 645000044 (Pos. 2), by pushing the wearing point
to the rear and then in its place.
Check the M16 x 65 mm bolt for eventual damages and replace it as required, item no.
690103190 + 690113008.

Maintenance
After 10 hours of operation, retighten the machine. Check hydraulic hoses, fittings and cylinders for
leaks and retighten.
Further check on a regular basis 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 lubrication, maintenance and repair, lower the Sub-Tiller, put the brakes of the tractor on and stop
the motor.
The 3.0 m, 3.5 m and 4.0 m Combi-Tiller (rigid) have 5 lubricating points, and the 4.0 m and 5.0 m
Combi-Tiller (hydraulic) have 20 lubricating points, all Combi-Tiller models must 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 at the movable linkage and at the cylinder as well.
The lubricating points on the hydraulic models are furthermore located where the wing sections are
hinged on the middle section and at the support wheels.
Moreover, the machines with hydraulic automatic release system have 2 lubricating points per tine
which are to be lubricated after 10 hours of operation.
Important!
Oil, type Hydro Texaco HD32 has been
filled in the hydraulic system.
