Commercial-Grade Durability

The HR 1040 R Series power harrows are built tough for intensive use with high-horsepower tractors. The central gearbox is offset to the rear to reduce shaft angles and eliminate interference from large-diameter rear tractor wheels. It is also filled with synthetic oil and equipped with an oil cooler to withstand high temperatures in commercial applications.

Heavy-Duty Rotors

The rotors on the HR 1040 R Series are driven by large-diameter gears with no-maintenance bearings. The power transmission to the blades is ensured by numerous teeth being fully engaged at all times for increased durability and long life.
