Speed and tractive effort. Have it all with WideRANGE, Tigercat's infinitely variable transmission for drive-to-tree feller bunchers and forwarders.

WideRange is a Tigercat-designed and field-proven single speed infinitely variable transmission that offers many benefits and advantages over traditional two speed transmission found in most competing drive-to-tree feller bunchers and forwarders.

Benefits at a glance

  • No need to choose between high or low range
  • WideRange provides the full speed range and full tractive effort available to the machine all the time
  • Mechanically reliable and field proven over millions of hours
  • Designed and manufactured by Tigercat

WideRange for drive-to-tree-feller bunchers

Drive-to-tree feller bunchers spend a great percentage of the total duty cycle driving – to the next tree or to and from the bunch pile.

WideRange allows the feller buncher operator to travel from tree to tree and to and from the bunch piles more quickly than competing machines equipped with a conventional two-speed manual shift transmission.

With WideRange full tractive effort is always available when the going gets tough. In addition, Tigercat operators always have command of the full speed range.

For example, the 724G equipped with standard 30.5×32 tires provides the operator with a speed range of 0-16 km/h (0-10 mph). With high engine horsepower and a large saw pump, the 724G has lightning quick saw recovery – ensuring that the machine is ready to cut the next tree before the operator is. So the only way for a top notch operator to further improve productivity is to reduce travel time. Quicker travel boosts productivity and reduces cost per tonne in high production thinning and final fell applications.

WideRange for forwarders

The 14-tonne Tigercat 1055C and 25-tonne capacity 1085C forwarders are also WideRange equipped. In both cases, the top speed is lower than competing forwarders equipped with a traditional two-speed transmission.

14-tonne class 1055C

For a 14-tonne class machine, once bogie tracks are factored in, the real-world top speed between the WideRange equipped 1055C and a competing class forwarder becomes very comparable at around 11 km/h (7 mph). In addition, in applications where the operator is not roading the machine from one jobsite to another, the higher top speed will very rarely come into play. What does the owner gain with WideRange? Significantly increased mechanical reliability and transmission lifespan.

25-tonne class 1085C

No forwarder will move wood uphill like a WideRange equipped 1085C. In the most extreme terrain, a WideRange equipped 1085C forwarder truly outshines. The machine has greater tractive effort, achieves higher working speeds, and carries larger loads up steep slopes than any competing forwarder.

WideRange for the 2160 loader forwarder

Designed for demanding wood yard applications, the 2160 loader forwarder must be able to carry loads around the wood yard quickly, reversing directions constantly, and often operating in very muddy ground conditions. The operator requires speed and high tractive effort in both directions in order to be productive ­– an ideal application for WideRange.
