Hydraulic Transmission
Closed hydraulic circuit for stepless speed variation in both rotating directions.
This machine is provided with a pull pre-setting system that maintains the pre-set pulling value(also when the speed is reduced to "0")by automatically adjusting the operation speed according to the friction and unexpected loads which may occur.
Configuration
Negative self-acting hydraulic brake
Hydraulic dynamometer with set-point and automatic control of maximum pull.
Hydraulic oil cooling system
Control instruments for hydraulic system and diesel engine.
Rigid axle for towing at max speed of 30km/h.
On board reel winder with automatic level wind,suitable for standard reels.
Pull pre-setting system
Mechanical front stabilizer
