TRI DRIVE concept

The driveline in the PÖTTINGER cutter bar is famed for its toughness and durability.

3 teeth are always in contact

The spur gear drive runs in a straight line with virtually the same sized gears. On the gears there are always three teeth in contact with each other – this ensures optimum power transmission. Moreover, there is less stress on the individual gears in the event of stone impact.

The specially ground surface of the gears submerged in gear oil ensures smooth running. This reduces the noise level considerably.

  • Gear set 39/50

  • Gear height 17.5 mm


Practical modular design

Bevel gears and bearings can be removed as a single unit The idler gears are also easily removed through the openings - it couldn't be easier!

The bearing flange and fittings are reliably protected by rubber o-ring seals. This prevents dirt or dust from entering the gearbox.

It also avoids oil leakage.


Heavy-duty bearings

The stub shafts of the individual mower drums have heavy-duty bearings. Durable, twin race taper bearings with a bearing spacing of 60 mm are extremely stress-resistant. Shock loads are absorbed effortlessly.


Bolted stub shafts

The high-strength stub shafts are bolted to the gears. Each of the parts can easily be replaced if required.

  • Shaft stub

  • Taper bearing

  • Bearing flange

  • Spur pinion


Cutter bar with durable driveline

The compact driveline and drive belt tension regulated by a back tension idler ensure robust and reliable power transmission. A freewheel is integrated into the gearbox.


Cutter bar without inside shoe

A key feature is the lightweight cutter bar without inside shoe. The driveline enters the cutter bar behind the first mower disc. This means you can mow into corners and over rough ground with no difficulty.
