High-tech Haulmaster takes data on-the-go

Thousands of hours of testing went into this data-gathering GPS cart that tracks grain from combine to storage

The new generation Haulmaster Grain Cart from Elmer’s Manufacturing has ushered in a host of technological innovations to streamline harvest.

Elmer’s engineers have remade the Haulmaster with a totally new frame and tank design that provides a better balance of height, length and width. To improve combine access, tank walls on all new carts are lower by 12 to 16 inches, depending on the model. The new tank improves combine auger clearance, making the task easier for the operator.

A new smart hydraulic auger fold-unfold system replaces the previous system, which limited folding speed to ensure it didn’t damage components. The Haulmaster PRO makes the auger fold start slowly, then speeds up to full hydraulic pressure, then slows down again for a soft landing.

The operator does a double tap on the joystick to activate the fold/unfold. The joystick also controls the auger flow gate, auger vertical pivot and the four-way spout, which has an auto-return to home feature. Smart hydraulics open up numerous possibilities for control of other implements.

Previous belt-driven auger assemblies have been replaced by a new Powermaster direct drive gearbox, which also contributes to the overall reduction in cart height. The new gearbox accommodates tractors up to the latest 600 horsepower-plus. Under ideal circumstances in testing, unload capacity has been pushed to 1,000 bushels per minute.

As harvest operations and grain storage become more complex, growers need to know the path and storage data on each cart load. The Haulmaster Connect system lets growers do that. Information stored on the grain cart controller continues logging data in the event of tablet failure in the cab. The direct scale connection allows detailed load tracking and scale diagnostics, plus a GPS module to track load locations. There’s a direct power connection through a seven-pin plug. This is a turn-key package with a tablet and window mount.

Elmer’s vice-president Mike Friesen says the new cart design included thousands of testing hours with custom harvesters, and included grain flow analysis, power-take-off torque testing and adaptive hydraulic timing among other factors.

“This ensures the cart gives the operator the absolute best harvest tools.”

He says the changes have been top of mind for the company for some time.

“Even from our first Haulmaster leaving the door in 2010, we had already started planning the big changes we see in this new Haulmaster.

“Our team is always looking for ways to improve our products, but at a certain point there are physical limitations of what you can do. Haulmaster PRO helps the operator overcome those limitations by pushing hydraulics to maximize efficiency.”

Growing demand for the Haulmaster, which was introduced earlier this month at Agri-Trade in Red Deer, has helped spur growth at Elmer, which has tripled its engineering team and doubled its production staff in four years. The carts come in model sizes of 1,100, 1,300, 1,600 and 2,000 bushels. Although 95 percent of all Haulmaster carts are on rubber tracks, there appears to be little interest in the driven-track option.
