9.1.2 LUV & soil
How can the LUV be adapted to the substrate / soil?
Recommendations, experiences and tips!
For depth control (e.g. in sandy soil) the disk
coulter with support wheel function (part No.:
01115/01116) is the right choice of ground
preparation tool. Additional units such as the power
harrow and under-vine rotary harrow in the modular
system are only recommended for use in light to
loose soils.
In hard or stony ground a rigid shaft (part No.:
01125) with grubber blade (part No.: 04128) or
½ duck foot (part No.: 01148) can be used as a
preparatory tool in the LUV unit. The ground is
torn up ahead by the use of a preparatory tool
and the LUV unit can work better. At the same
time, the rigid shaft protects the central blade
shaft of the LUV.
9.1.3 LUV – attachment, operation and maintenance
The LUV does not actuate correctly or else too late
End cut-off screw
The upper screw (see page 22, item number 3) is has been turned in too far.
no oil circulation, since the return flow line is not open
the position of the screw is crucial for oil circulation
How can I determine that?
- Turn on the control valve at the tractor, observe the engine rpm!
Speed drop pressure is being built up
Solution:
Stop the tractor engine and unscrew the upper screw
Check the détente stop of the valve stroke limiting screw
(see page 22, item number 2)!
- Valve plunger movement 2 – 5 mm oil circulation
Check the hydraulic connections at the LUV and the tractor (see page 15, item
number 1)
