Rubber Tire Trencher: Toro

The Toro RT600 riding trencher is built to deliver smooth, consistent performance in tough digging conditions. The RT600 is the only trencher in its class using a flywheel, torsion shaft and planetary gear reduction system. The flywheel minimizes trencher stalls, the torsion shaft absorbs shock loads from the drive train, and the planetary gears multiply hydrostatic motor torque to provide unsurpassed trenching power.

Toro also instroduced this trencher in 2014:

The RT1200 is an all-new riding trencher designed with versatility and productivity in mind.

Built on a tool carrier chassis, its design is extremely versatile to allow contractors to select from tracks or tires and a variety of attachments – including a backhoe, 6-way backfill blade, rocksaw, vibratory plow, reel carrier and the Toro-exclusive Heavy-Duty (HD) trencher drive.

The Toro HD trencher drive consists of three major components – a flywheel, torsion shaft and planetary gearset. The flywheel stores inertial energy, ensures efficient hydraulic system operation and keeps the chain consistently running in tough digging conditions, the torsion shaft absorbs shock loads and the planetary gearset multiplies the hydrostatic motor torque for added digging power.

The RT1200’s P105 Vibratory Plow features plow-blade attitude adjustment, as well as plow steer and swing of up to 30 degrees to maintain plowing accuracy and provide enhanced maneuverability. With its open-design operator platform, easily accessible controls mounted to the arm rests, multi-adjustable high-back suspension seat and large digital display, the RT1200 provides the operator with great visibility and comfort to ensure maximum productivity.

Additionally, its Cummins 4.5 liter, 121 hp engine and 48 gallon fuel tank provide high output with minimal downtime. A standard tilt frame allows the operator to tilt the machine at variable degrees in order to maintain trench angle, while optional load control allows the operator to set the percentage of engine output dedicated to the ground drive to ensure the performance of the digging implement is maintained.
