With a 210-degree rotation, the swing boom increases the working envelope of the skidder which means the operator spends less time manoeuvring the machine.
Tethering device set-ups are reduced due to the wider working range.
Dual rotate motors and a large swing bearing make gathering and moving bunches effortless on steep slopes.
Lock and release the 220 degree rotating seat in any position with the touch of a button. Full machine controls are always at your fingertips.
Small details like a climate-controlled cup holder and a place to hang your hat make long days feel shorter.
The 4-point harness makes extreme terrain feel a little tamer.
The durable interior finish is easy to clean.
The 635H swing boom system uses field-proven heavy duty components common to Tigercat track machines.
