A harvester head grips a tree stem and feeds it through delimbing knives at speed — the feed roller drive must apply high, precisely controlled torque that never stutters, or the stem slips and the cut length is wrong.

Motor roles in this machine

• TMS03 — feed roller drive: Sphere-piston radial motor delivers smooth torque from 2 r/min, gripping and feeding stems of any diameter without ripple-induced slip. TMS03 reference →
• Compact and impact-tolerant: The motor lives inside the head, taking branch strikes and weather — heavy-duty bearings keep it in service through the season.
