Kuhn’s new generation of square balers is called the SB series. It consists of four double-knotter models (SB 890, SB 1270 X, SB 1290 and SB 1290 iD) that produce 80x90cm, 120x70cm and 120x90cm bales.

The series has an upgraded driveline, heavier duty flywheel, load-sensing hydraulics and a torque regulation system.

Intake

The SB series balers feature an improved crop intake system.

The new crop guard, in addition with a torque increase on the rotor and on the feeder fork driveline, delivers a 15% higher intake capacity than the previous LSB series, according to Kuhn.

The company also claims the patented torque regulation system on the SB series allows for a good balance between capacity and density.

The crank angle position sensor and plunger rod load pins measure the total machine load.

More precise measurements are performed throughout the complete plunger cycle. The excess measuring can lead to a gain in bale weight.

Features

The new design offers increased accessibility for maintenance. The knotter deck is equipped with a solid stairs and a safety railing.

The SB models are equipped with Kuhn’s full-width integral rotor. They feature an active pre-chamber filling mechanism with a newly designed mechanical feeder fork steering system.

A double-knotter binding system comes with standard electronic twine monitoring. The SB models are fitted with a load sensing hydraulic system.

This system is used for axle locking, knife steering, the roller chute and bale ejection. The SB range is fully Isobus compatible.

SB 1290 iD

Kuhn produced the SB 1290 iD for high-density baling.

The company claims this baler produces square bales with up to 25% higher bale density than conventional 120 x 90 balers thanks to a double-plunger system.

This helps to maintain high bale compaction while avoiding high peak loads on the machine.

Despite the heavier bales, the load on the machine is comparable to a conventional 120 x 90 baler, eliminating the need for an oversized driveline, flywheel and mainframe.
