Patented harrow tine spring system.

The only manufacturer that has been producing the original harrow for well over half a century is introducing a completely new patented harrow tine spring system in time for the 2020 season.

The engineers at Hatzenbichler developed a system with which it is possible to continuously adjust the tine pressure at a constant tine angle

The Air-Flow harrow

The spring action of the tines is provided by a pneumatic cylinder with a spring travel of only 30 mm, which enables a 45° spring path of the tines.

The central air supply is provided by the compressed air brake system of the tractor. A proportional pressure regulator enables the cylinder to be pre-tensioned in the 1/10 bar range up to a maximum of 6.0 bar.

In this way, the tine pressure can be infinitely adjusted from 500.00 – 5000.00 g. Uniform cultivation of ridge crops and uneven soil conditions is thus guaranteed.

In contrast to the tension springs pre-tensioned with wire ropes, the new Hatzenbichler harrow features actual constant tine pressure.

 

The tine aggressiveness

In addition, the tine angle and thus also the tine aggressiveness can be adjusted within the range of 57° – 102°.

As far as is known, this is not possible with any other manufacturer. Due to the wide bearing of the tine holder, the lateral deflection of the tine is minimized. A passage height of 590 mm allows the harrowing of higher crops.

The 1.5 m field and a tine spacing of 25 mm ensure optimal ground hugging.

Since the new harrow arrays including pneumatic equipment can be mounted in the Hatzenbichler harrow frames, which have been tried and tested for decades, any working widths can be done from the ground up.
