Rayco T415 forestry mulcher and hydra-stumper from Morbark


M


orbark, LLC, announces the debut of the new Rayco T415 Forestry Machine. Designed


for land-clearing companies, construction companies, pipeline contractors, electric utility contractors, and real estate developers, the T415 allows customers to change between a Predator forestry mower/mulcher head and a Hydra Stumper stump cutter attachment for optimal versatility. Powered by a 415-HP (310-


kW) CAT C9.3B Diesel Tier 4 Final engine, the T415 has 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 motor(s). The hydraulic output is power- optimised to match 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 gets more power at the cutter head over a broader engine RPM band.


Intelligent boom control now available for the 1470G Harvester


Intelligent boom control (IBC) is the unique boom control system developed by John Deere. It’s an intelligent control system with sensors that detect the positioning of the harvester head and algorithms that adjust the boom’s trajectory in one continuous motion. IBC also functions as a platform for the eventual and easy introduction of new features that facilitate the customer’s work. “IBC brings significant advantages


also in final fellings. Thanks to IBC, controlling the big and robust CH9 boom is just as easy and precise as in the smaller harvesters, and the boom can be operated at the same speed as the booms in the smaller harvester models. IBC facilitates the operator’s work and makes working more pleasant. There are fewer movements to make – and that

helps with the operator’s working capacity. It’s a feature of the modern era,” says Marketing Manager Tommi Ekman. In harvester work, the IBC’s


operation has been designed to suit the machine’s work cycle. The boom’s trajectories and operation automatically adjust as the boom is taken to a tree and the load is in the harvester head. The operator doesn’t have to move the different sections of the boom individually. The boom is easy to use and precise at all boom reaches. Thanks to the electronic end damping, the boom operates softly. The blow-like loads at maximum reaches are eliminated, making the operator’s work more pleasant and decreasing the stress on the boom’s structures and hydraulic cylinders. IBC improves work ergonomics and guides the

operator in the correct use of the boom, which is directly reflected in the increased productivity. Intelligent Boom Control


was introduced for John Deere forwarders in 2013. In 2017, John


Deere introduced IBC first for the 1270G harvester and later the same year also for 1170G harvester. Now IBC will be available also for the 1470G harvester’s 11- and 10-meter CH9 booms used in final fellings.
