Rockhound Attachments FX26 Defender forestry cutter

The preliminary design review for The FX26 Defender forestry cutter entailed some decision making. One of the first decisions you are faced with is deciding how to transfer power from the power source let us call this (A), to the mechanism that needs to be driven, which we will call (B). The starting point in making this decision is determining if (A) can connect directly to (B) as direct drive is the most advantageous arrangement from both an efficiency and maintenance standpoint. The decision to pass the power through a power transfer system (such as belts or gearbox) (C) will, under the best of circumstances immediately consume 5-10% of the energy. The decision to add (C) should only be made when the (A)-(B) arrangement cannot accomplish the requirements of the design. 


Since the FX26 Defender was conceived as a means to bring a power intensive capability to a low horsepower platform, not sacrificing the 10% was imperative and is just one of many design factors that made the FX26 Defender Forestry Cutter possible.
