Unique features of GMT grapple saws

Safety

Safety first: grapple holds tree trunk at maximum pressure, before cutting starts
Horizontal back ribs to secure tree trunk from slipping in every position
Tilt cilinder blocked when sawfunction is enabled allowing you to control tipping of tree trunks after cutting. On a model with Total Tree Control: not only is the tilt cylinder of the grapple blocked, but so is the movement in all directions in the cardanic suspension, to enable tree sections to be held after sawing

Efficiency

Patented manifold enables plug-and-play installation without any changes to your crane or vehicle
Easy accessible manual operated ball valve to block sawfunction allows you to use the machine as a normal grapple
Saw oil tank capacity enough for a full working day
Compatible with all 173 mm rotator types. On a model with Total Tree Control, rotator, link and crane point are included

Quality

All components made of high quality Weldox steel
Special designed saw bar prevents losing your chain
Chain tensioner based on many years of field experience
Hydraulic lines are well protected
