Power harrow HR series

with rollercombined

Overview
SKY rotary harrows are designed for combined operation with seed drills. The hopper inclination and shape enable efficient rear discharge, preventing settling in front of the hatch. A higher front weight of the loaded hopper shifts load to the tractor for improved traction. The machine remains stable even when unladen, ensuring consistent ride comfort.

Main advantages

• The incline provides excellent rear emptying, avoiding compaction ahead of the hatch.
• Front-weighted hopper transfers part of the load to the tractor for maximum grip.
• Stable behaviour when unladen for improved comfort and handling.

A perfect seedbed
4 rotors per metre deliver a uniform seedbed without swaths or ridges and reduce traction requirements. Chassis made from reinforced steel.

Tapered roller bearings
Heavily dimensioned tapered roller bearings combined with a large-diameter shaft maintain adapter alignment under severe conditions. Factory-fitted with a spacer; no further adjustment required. This modern bearing solution enhances reliability and resale value of the implement.
