The planetary trencher drive uses a fly wheel, torsion shaft and planetary gearset for smooth operation and longer life. The flywheel keeps the chain line from stalling in tough soil conditions and minimises pressure spikes in the hydraulic system. Between the flywheel and the planetary gearset, the torsion shaft serves as a spring to absorb shock loads from the trencher driveline. The planetary gearset multiplies the hydrostatic motor torque for unsurpassed digging power. These features all combine to deliver smooth, consistent, and powerful trenching, even as ground conditions change.
