The new head manufacturers are based in the USA and have teamed up with TimberPro.
Timberheads is an American company started in 2008, which is based in Wisconsin. They set themselves the goal of building a simple, reliable and affordable processor to handle the largest hardwoods, but still operate efficiently in softwood. The focus has been on building heads of high quality that will last a long time in difficult operating conditions. Timberheads indicate that their team has learned from many years of experience in operating & building some of the industry’s best forestry machines. The heads can be installed on excavators or wheeled harvesters. They can provide options to meet the individual needs of the customer.
The main body of the Timberheads processor is constructed from laser-cut, high alloy 100KSI steel, with the knives been made from even higher grade steel. The steel pieces are fitted together with precision, and after welding is complete, the structures are stress relieved before machining. All machining is done as a unit to achieve precise alignment of all bores. This reduces unnecessary wear. All main pin bores have a hardened steel sleeve fitted to tight tolerances, giving extended life to the structure and allows for easier future rebuilds. Pins and bushings are manufactured from high-alloy polished and ground steel.
The Timberheads Kodiak TH24D is a 1,678 kg (3,700 lb) head designed to harvest trees up to 61 cm (24 in). The Kodiak TH24F is also designed for 61 cm (24 in) trees, but weighs 1,944 kg (4,285 lb) including the rotator. Source: http://www.timberheadsllc.com/
