H Y D R A U L I C T R E E
H A R V E S T E R
The power of the previous HTH622, with more speed and less weight
• NEW Stronger body design with strengthened hanging bracket, double shear pins. More butt flare which enables a lower stump height when felling
• NEW Additional clearance for the saw unit and higher visibility throughout the head
• NEW Re-designed hydraulic system with all functions integrated in main control valve
• NEW Hose routing for protection and increased hose life
• NEW Easier access for pressure test and valve maintenance, with on-board pressure diagnostics
• NEW Fixed knife in saw unit and lockable front knife for debarking
