Why Haulmaster?
The Haulmaster unloading speed exceeds any other chaser bin on the market. It features an unloading auger that can empty up to 18T per minute.
Elmer’s Powermaster direct drive gearbox further increases the auger output capacity for any given tractor power, to provide even more efficient unloading.
The full-length horizontal auger clean out allows for quick grain transition, and makes cleaning out the chaser bin simpler and faster. The horizontal auger can also disengage separate to the unloading auger in the event of a blockage.
All Haulmaster Chaser Bins include Elmer’s exclusive Powermaster custom designed direct drive gearbox. The Powermaster gearbox eliminates belts and drive chains to maximise grain flow efficiency and increase auger output capacity for more efficient unloading.
The Haulmaster has bolt together, smooth wall, modular design which ensures maximum durability and prevents cracking and seam failures.
Adjustable discharge auger and 4 way pivoting spout allows for easy loading of trucks and motherbins and accurate distribution of grains.
There is also the option of left or right folding auger with a 30 degree pivot range.
Loadcells are compatible with Agrimatics Wireless display, Haulmaster Pro and Haulmaster Connect Systems.
Elmer’s have developed their own exclusive tracked undercarriage.
Combat wet conditions and compaction with Elmer’s exclusive track design built specifically for the highest capacities and toughest conditions, and is low maintenance. Tracks are available standard on the 46T and 55T models while the 30T and 36T have an option to include Elmer’s Transfer Tracks.
