HE-VA Deep Rippers (Sub-Tillers) are available in 5 different frame models in Australia: 3m & 4m Linkage, 5m, 6m & 7m Hydraulic folding trailed models. All models imported to Australia are fitted with hydraulic tines.

For stony soil types a deep ripper with hydraulic automatic release system is recommended. With a hydraulic cylinder mounted on each tine, which is connected to two gas accumulating tanks, an automatic swing of a tine is ensured, if it comes into contact with immovable stones. This system is also functioning as a shock absorber in stony soils, where it will catch the vibrations.

The working depth is controlled exactly by the hydraulic adjustable packing roller. The driver can see the actual working depth with the depth scale.

The roller is a serrated ring of pressed steel with a shoulder profile ensuring an aggressive breaking of clods and by this a perfect surface finish. Effective scrapers are mounted between the rings making preparation in moist and sticky soil conditions possible. The 3 pt linkage models have a 600mm V-profile and trailed models have 700mm V-profile.
