HYPRO 755 Tractor Processor

The HYPRO 755 is a generously equipped tractor processor with its own 7 metre feed crane and processor head, both of which have a working radius of a full 280°, in other words, processing from both sides. HYPRO 755 is also available without crane. HYPRO 755 has its own hydraulic system with pump and tank for mounting on the front of the tractor. The hydraulic system is variably load-sensing, providing speed, flexibility, excellent flow and strength in combination with maximum fuel economy. HYPRO 755 can also be supplied for mounting on tractors with an inbuilt variable hydraulic system with the necessary flow and pressure (see technical data).

HYPRO 755 Tractor Processor

HYPRO 755 is supplied equipped with the HYPRO+1 control system, which is HYPRO’s third generation Canbus-system with 2-lever electro-hydraulic control (EHC). The system has pre-sets for up to three different operators, enabling a range of settings to be stored for each operator in relation to crane- and processor control. For example, the driver can change the joysticks’ hysteresis curves, ramp times, MIN/MAX speeds, balance and invert (turn) the direction for all crane functions etc. All to be able to very simply and clearly set the machine’s functions according to the driver’s different needs and wishes.

MD430-DA Measuring system is a part of the HYPRO+1 control system and has both length- and diameter measurement, as well as automatic functions for processing and logging with smart control via the processor’s assortment list and CAN. The operator can select to process the log manually via joystick movements, via pre-set length selections or via fully automatic mode where the measuring computer itself selects length to cut according to the diameter of the trunk and the pre-set assortment list that the operator can set up. The automatic cross-cutting system substantially increases the machine’s capacity and is easy to learn how to use as a new operator.

The measuring computer has an LCD colour monitor with large white numbers that are easy to read even in strong sunlight and a wide viewing angle. Photocells automatically start and reset the measurement cycle, while a separate measuring wheel with a pulse encoder sends signals to the measuring computer. MD430-DA saves log data for potential print out via USB, and also displays selected pre-set length/length suggestions during operation depending on the diameter of the trunk and the assortment list that can be set by the operator.

If required, selection of tree species takes place by means of a simple press on the respective joystick button for spruce, pine, hardwood or misc. 1 and 2. Log data is registered automatically with each cut and is saved in the measurement list in the measuring computer. The measuring computer logs volume and number of pieces cut for Sawlog large, Sawlog small, Sawlog short and Pulp for several different assortments. The unit also has inbuilt cable troubleshooting, calibration of length and diameter measurement, as well as a set interval for servicing the machine. Computer program and cables to connect the measuring computer and save log data to a PC are included.

The HYPRO 755 is a fantastic processor for both thinning operations and final felling. Fully 280° slewing radius and lateral displacement provide ample adjustment to suit the direction of fall of the tree and allow distances of up to 3.3 metres between timber stacks. The machine has a radio-controlled winch enabling winching in from both sides. The design of the crane, with a tilting crane pillar, gives a low centre of gravity at full reach, as well as compactness when folded. Hydraulic support legs are always included. A tractor with a reversible driving position fits perfectly together with a HYPRO 755 tractor processor to produce a fast, effective and highly competitive harvesting machine.
