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


Smooth-running driveline

A standout feature of our mowers is their supremely smooth running. The NOVACAT series features a friction-locked drive train directly to the first mower disc. A constant velocity joint provides a stress-free link between the angular gearbox and the cutter bar.

On all mowers, a freewheel is integrated into the driveline.


Robust driveline

All drive elements are robust and large dimensioned. The central T-gearbox, together with the long cardan shafts, ensures reliable power transmission and smooth operation. A freewheel is integrated into both drive shafts. Overload protection is provided on the input PTO shaft.
