New Holland D710 S Ballenst. – specifications

A square baler such as the BB960 A ASY picks up swathed forage with a pick-up and compresses it in sharp strokes with a reciprocating plunger inside a rectangular bale chamber, forming a square bale. Unlike a round baler, the bale is built up in layers under the plunger's pressure, which allows high bale density and therefore a high weight per bale. At the end of the chamber, the machine ties the bale with several strands of twine before it slides out over a ramp.

Size depends on the tractor power needed for the pick-up and plunger drive, which on a square baler is markedly higher than on a round baler because of the shock loading involved. On the road, the trailed implement is subject to the general rules on width, lighting and marking.

On a used machine, what counts is the condition of the plunger and its bearings for play and wear, the function of the knotter unit and twine brakes, the condition of the pick-up tines, and cracking in the bale chamber. The flywheel and its overrun clutch should also be checked for unusual noise. It is also worth checking the chassis tyres and the hydraulic hoses of the bale discharge, which are put under particular strain on a square baler.
