The Lowlander Mk4 range is Bunnings small-to-medium sized vertical auger offering. They extend from the Mk4-75 with a 9.5-tonne carrying capacity up to the Mk4-150 with a 16.6-tonne carrying capacity.
All Mk4 models have twin 695-mm diameter vertical augers with flights laser cut from heat-treated boron steel to improve strength and service life.
Reversible hardened boron steel cutters are bolted along the back edge to shred the manure and create a wide, even spread. Three fixed bottom blades on each auger give a wider spread of materials that are either fine or wet.
