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.

Gearbox Temperature and Clutch Monitoring

Operators of all skill levels will have no trouble running the machine or making adjustments. A simple monitor with colored warning lights helps keep a close watch on the gearbox temperatures and cam clutches to avoid costly damage. Hydraulic adjustments for the working depth and leveling bar reduce the need to leave the tractor cab, while still adapting to changing field conditions and soil types.

Perfect Soil Leveling

A level soil profile is essential for consistent planting depth. The integrated leveling bar features a hydraulic adjustment separate from the working depth, while each half of the power harrow can run in a floating position to best match the contours of irregular fields. Long side deflectors ensure excellent finishing between passes for an ideal seedbed.

DuraKuhn Blades

The DuraKuhn blades are adapted for intensive use in the most difficult of conditions. These blades are heat treated for extreme longevity out in the field. The blades are also 18 mm thick and use Fast-Fit® technology for easy replacement.

Transport Width

The HR 1040 R Series power harrows fold easily to a narrow 9’10”. This provides rapid transition from transport to field and back. Practical, fast and easy to maneuver on roads and in fields with narrow gates.
