The 635D is Tigercat's highest capacity skidder. With six-wheel drive and a massive grapple, the 635D is best suited to extremely soft or steep terrain, long distance skidding, oversized logs and high production continuous duty cycle applications.
Turnaround™, the new two-position rotating seat, is standard equipment for the 630D. With all controls available, the operator can comfortably back-up while facing the rear for reduced strain, quicker travel speeds and higher productivity.
The difference is in the drive...
Electronic control technology combined with Tigercat's unique hydrostatic drive system allows the 630D skidder to operate at variable engine rpm, automatically increasing engine speed when additional horsepower is demanded.
The result is improved fuel economy and reduced engine noise. No gear changes are required of the operator.
