Hi-Spec's Vertical Auger range of feeders is available in both single and twin auger variants and sizes from 7m3 to 32m3 and a unique knife arrangement allows them to be used with lower horsepower tractors to achieve a successful and quick mix.

They use a low pitch mixing and chopping auger that creates a simple cycle action and is fitted with eight self-sharpening knives one of which runs close to the body of the feeder. This ensures that once the mix is drawn up by the auger, as it falls back down the side it continues to be chopped and mixed, ensuring a quick and thorough mix.

Options includes various discharge outlet positions or a variable height hydraulic chute or cross conveyor with elevator. It can also be specified with the Digi-Star TMR Tracker fully programmable electronic weighing system and can be fitted with a straw blower so that it can also be used as a bedder, or with a root washer so that root crops can be incorporated into the mix.

The straw blower attachment comes into play after the vertical augers have initially broken down the bale and the straw then passes through a high speed flywheel that blows the straw up to 20m through the chute, which can rotate through 30°.

Hi-Spec's MixMax paddle-type feeders are designed to be flexible, sturdy and economical, with a long lasting and simple design. They use the Feed-Flo mixing system that features a single angled rotor arms to provide thorough end-to-end mixing and a light fluffy ration without the need for multiple augers.

The mix is discharged through a hydraulically operated door through a teaser roller that makes it easy to adjust the flow rate and provide an even, consistent feedout.

A total of seven single and double axle MixMax models are available, ranging from 10m3 up to 24m3. Options available include the Digi-Star Tracker programmable weighing system, a hydraulic or fold-down elevator and a root washer and chopper for incorporating root crops into the ration.
