Timed knife arms and triangulated feed wheel arms for fast picking and positive control.
The optional back knife arm position helps align the trees in the head to maintain positive contact with all three feed rollers and the measuring wheel at all times.
Strong components, large bushings and pins, and durable construction throughout result in less downtime and higher production.
The 573 is standard equipped with continuous rotation for ease of use and superior hose routing and protection.
Quick, stable WiFi connectivity between the cab and attachment modules reduces wire routing along the boom and provides excellent command response.
