With modern technology in line with European standards, the new machine TAF 2012 from IRUM, a machine designed in our Research and Development Center, characterized by performance, efficiency and comfort at Western level. The PERKINS brand high-performance engine, modern power steering system or performance gearbox are just some of the high quality components integrated by IRUM in the new TAF 2012 machine: all systems of the predecessor 2010 have been redesigned for greater efficiency and comfort, resulting in a really focused on user machine. What does that mean for you? Numerous technical and ergonomic improvements to the machine reduce physical and mental stress on the operator, meaning – in addition to a comfortable workstation in any season – increase of operational productivity.

Being perhaps the most important component of the machine, the TAF engine must adapt to extreme work conditions, but to be reliable, easy to maintain and economical at the same time. This is precisely why we have chosen the experience and skill of PERKINS Company, the world leader in diesel engines for agricultural and industrial applications. The 1204E-44TA model used in TAF 2012 is part of the manufacturer’s newest range, developing 110 HP and designed in accordance with the new EU Stage IIIB standards (EPA Tier 4 Interim, MLIT Step 4). The engine is coupled to a 5-steps synchronized gearbox, and uses a hydraulically driven clutch. Also, the machine has multi-disc axle brakes in oil tank and differential lock, 2 x 8 tonnes hydraulic winch and mobile shield.

Also, the exceptional comfort and equipment are strengths of the machine. From the adjustable driver’s seat with air cushion and heating in the seat and back up to the load monitoring camera, TAF 2012 will ease both the work performance and your comfort on their duration, and the very good heat and sound insulation ensures a well-protected workstation in any season. The machine cabin, in addition to enhanced robustness and ROPS, FOPS and OPS certification is tilting 45° to the right to ease the work in inaccessible places, and the location of controls was redesigned for added ergonomics and comfort in use. Even the steering column is adjustable too.

The new TAF 2012 from IRUM is a Romanian forestry tractor with western performance, standing out by the latest technology, efficiency and comfort.
