NONSTOP ploughing in stony soil

SERVO NOVA ploughs with stone protection gives maximum reassurance. Ploughing without stopping means full productivity even in stony soil.

A hydraulic overload protection system with adjustable triggering force protects the plough against damage.

Stone protection SERVO NOVA

Hydro-mechanical stone protection

This system has a very clever triggering pressure system: The leg does not trip until the set resistance has been reached. Then the pressure required to trigger the leg reduces as the leg rises. No digging or loosening of big rocks. This protects the whole plough.

On re-penetrating the soil, the pressure increases to ensure reliable penetration in heavy, dry soil.
Set the trigger point quickly and easily using the pressure gauge on the headstock.

Proven system

With its variable hydraulic triggering pressure, the SERVO NOVA system adapts the plough to different soil types.

Each pair of plough bodies has its own hydraulic accumulator which allows upward movement to the side by up to 40 cm.

The lubricated pivot points and additional shear bolts guarantee a long service life.

The central filling system is standard on all SERVO NOVA ploughs.
Smooth, flexible triggering protects both plough and tractor.
The gas accumulators are mounted on the inside of the plough legs for protection.
Spring-mounted disc coulters roll over rocks without the risk of damage.
