Six wheel skidder
With six-wheel drive and a massive grapple, the 635G is built for extreme duty and super high production logging operations. Ideal applications include very soft or steep terrain, long distance skidding, oversized logs and continuous duty cycle around-the-clock applications.ﾠ
The difference is in the drive…
Hydrostatic drive offers many advantages. Performance in tough terrain is excellent because full tractive effort is available at any engine speed, minimizing wheel spin and improving breakout performance. The operator appreciates simplified drive control with no gear shifting.
Electronic control technology combined with Tigercat’s unique hydrostatic drive system allows the skidder to operate at variable engine rpm, automatically increasing engine speed when additional horsepower is demanded. The result is improved fuel economy.
