570 Harvesting Head

The Tigercat 570 is a durable, high performance two-wheel drive, three knife arm harvesting head, specifically designed to match the high performance capabilities of Tigercat carriers.

With independent knife arms, the 570 harvesting head excels in tough timber with large limbs and poor stem form. Independent knife and wheel arm improve stem contact. This results in superior feeding, delimbing, measuring and debarking, especially in sub-optimal stem form conditions.

The 570 also has optional hydraulic knife timing for easier picking in roadside processing applications.

Key Benefits

  • Larger diameter hoses and larger capacity valves than similar class heads to match the greater hydraulic flow and power of Tigercat harvester carriers
  • Robust design, high quality components for high duty cycles and long life
  • Precise diameter and length measuring
  • Efficient hydraulics for high performance, efficiency and improved carrier component life
