The heat in far north Queensland makes water retention in plants very difficult. A layer of mulch around the base of the plants helps to stop the water from evaporating.

But with several thousand trees to mulch, the owners of this Cooktown fruit orchard, have opted for a Roto Grind, supplied by RockHound Attachments Australia ,to grind such large quantity of straw. This, is then directed to the trees base or garden beds and used as mulch. The fully adjustable exit spout allows complete control of distance and direction of the ground material.

The Roto grind tub grinder’s simple but effective governor system allows the same machine to use tractors from 70 to 200 horsepower. The operating rpm can be adjusted to between 540 and 1100 rpm. Additional attachments for grains and specialty grinding are easy to install and operate.

With only 2 moving parts and 1 wearing part, maintenance of the Roto Grind rotary is an extremely simple process.
