The T415 allows customers to change between a Predator forestry mower/mulcher head and a Hydra Stumper stump cutter attachment for optimal versatility.
The Rayco T415 Forestry Machine is designed for large scale land-clearing companies, construction companies, pipeline contractors, electric utility contractors, and real estate developers. It is powered by a 415-HP (310-kW) CAT C9.3B Diesel Tier 4 Final engine. The T415 boasts a closed-loop hydrostatic system to power the mulcher or cutter head, sending 140 gallons per minute (530 L/min) to the attachment’s drive motors. The hydraulic output is matched to the engine’s power curve, keeping the mulcher/stumper RPM constant even under load for a finer mulched product with fewer passes. As the engine RPM pulls down under load, pump displacement increases to maintain the 140 gpm flow. The operator feels more power at the cutter head over a broader engine RPM band.
For mowing/mulching applications, the Predator mulcher head has a 91.25″ (232 cm) cutting width and is powered by a pair of variable displacement drive motors. The Predator mulcher head is equipped with 49 single-bolt teeth, including end teeth with extra carbide to power through anything its way. The mulching head also has a synchronous drive belt for low maintenance and long wear life and slotted mounting lugs to follow the terrain with minimal machine stress. A manually adjustable tree catcher and hydraulic debris flap is standard equipment.
The Hydra Stumper head processes stumps up to 48″ (122 cm) diameter using a 3″ (7.6 cm) thick cutter wheel equipped with 56 Monster Tooth™ cutter tools. The cutting range is 9′ (2.74 m) wide, 8’10” (2.69) high and 46″ (116.84 cm) deep.
Rayco’s patented elevated cooling design places engine radiators in both the rear of the engine compartment and in the limbriser for maximum cooling in even harsh environments, including areas with high ambient temperatures and a considerable amount of airborne debris. Debris screens trap airborne chaff before it can plug radiator fins. These screens are easily removable without tools for cleaning. Reversing fans also clear debris screens on-command, extending service intervals. The fans run at variable speed based on temperature and reverse based on a timer or by manual control from the operator’s cab. An on-board air compressor further aids in cleaning debris screens.
Other key features include Rayco’s exclusive track tensioning system with monitor, which alerts the operator to over-tension situations and provides easier access to track tension grease fittings; hydraulic tilt cab to access pumps and other components easily; and the heavy-duty 35,000-lb (15,875-kg) hydraulic rear winch. A number of safety features are designed into the T415, including high-output LED lights on all four sides of the machine, emergency e-stop button, and an escape hatch in the roof of the cab. The ROPS/FOPS/OPS-certified cab also includes several comfort and ergonomic features and a rear-view camera. Source
