The Ajust-a-bar® is an alternative to a disc chain, with full control over aggression and depth of cut.

Instead of adding more and more cast weights to a chain, Ajust-a-bar® has a hydraulic accumulator system which allows pressure applied to the gangs to be increased as needed and to suit soil type.  Alternatively for a lighter level of cultivation the gangs can be allowed to float therefore having the ability to handle rougher country (stones etc) as each gang can jump up to 10″ or lighter loam soils. This creates a multi purpose harrow for use in:

  • secondary cultivation eg full cut on the front gang at 35 degrees at 2″ depth
  • cutting trash
  • stubble management by adjusting aggression, simply open machine up to enable you to cut stubble with minimal soil disturbance

It’s not a speed tiller, not a chain bar, not a stubble cutter but a combination allowing a level of all of these things. Have a look at our photo gallery and video gallery to see an Ajust-a-bar® in action.

NOTE this machine has not been developed for heavy primary cultivation, it is not an offset disc, it is a disc chain alternative.

The big benefits are reduction in burning by allowing tillage gear to pass through heavy stubble’s, an economical reduction in chemical use assisting in herbicide resistance control.Single pass with an Ajust-a-bar

The Ajust-a-bar® has only been released so far as an M8 – 46′ model (14 metre), a wider model to allow greater coverage of country is in the pipeline contact us for more details.

The M8-46′ model is available in two options, a standard or light option and a heavier optioned model. The heavier optioned model is designed for farmers with harder country and tighter soils. The standard bar is ideal for the majority of broadacre cropping country.

There is also a drawbar extension option available for those who require it .
