Hay & Silage: Pottinger A9 mower combinations

The Pottinger Novacat A9 mower combinations have proven a great addition to the Pottinger mower stable and are continually proving themselves out in the field

With working widths from 8.92 to 9.18 metres, the mowers are packed with excellent technical highlights. The A9 mowers are available in mower only, tine conditioners, and roller conditioners models.

The Novacat A9 rear mowers are used in combination with the popular Alpha Motion PRO front mower. Working width is adjusted simply using the two mounting positions. The overlap in the narrowest position using a three-metre front mower and the rear mower combination is 52cm; in the widest position using a 3.5-metre front mower, it’s 60cm.

The powerful centre frame combined with the ‘Y Drive’ driveline and hydraulic non-stop lift collision safety device ensures that the A9s are prepared for the toughest of conditions.

Y Drive – new generation driveline

The special Y Drive input gearbox with bevel-cut gears features an output shaft on the opposite side. This means that longer standard PTO shafts can be used with less angle. The backlash-free driveline using standard PTO shafts has been made possible by locating the overload clutches at the gearbox and by optimising the gear ratios. The constant velocity joint in the inside mower drum provides a stress-free link between the angular gearbox and the cutter bar. The result is a smooth-running system that offers higher output, even in tough conditions and in the headland position. This also extends service life significantly.

Nonstop lift– the new hydraulic collision safety device

Nonstop lift is an innovative technology that ideally protects the cutter bar. Fitted to both ends, the collision safety device enables the cutter bar to avoid obstructions efficiently. The special feature is that the boom is mounted on gimbals and is hydraulically preloaded by a triangular arm. The triggering pressure is displayed at the pressure gauge and is easily adjusted. When triggered, the boom folds backwards on the triangular
frame and is also raised at the front by the gimbals – a three-dimensional collision safety system. The mower avoids impact with the obstruction so that damage to the cutter bar is prevented at higher driving speeds.

Proven a thousand-fold – the Novacat cutter bar

The heart of the mower combination is the cutter bar proven thousands of times in the field with its unique Tri-Drive gear driveline and sprung-loaded quick-change blade system. Tapered disc surfaces, optimised counter-chop zone, and generous overlap of the blade paths ensure perfect crop flow, first-class cutting quality, and simultaneous optimum protection of the swath.

Compact during transport, space-saver when parked

For road transport, the mower hydraulically folds upwards and then is locked securely in the transport position. With a transport height of under four metres and a transport width of 2.95 metres, the A9 is compact during transport. Parking stands are provided so that they can be stowed in the raised position to save a great deal of space.

Easy maintenance management using the control terminal

The mower combination is equipped with the Select Control terminal as standard (requiring a double-acting remote valve). It allows pre-selection of the mower units, control of the folding side guards, and the hydraulic transport interlock. The control terminal also has an integrated maintenance management feature – dependent on the operating time of the mower driveshaft, the control terminal displays which maintenance steps need to be performed on the machine. Setting the weight alleviation is easily done using the shut-off valves located under the rear panel of the mowers.

First-class cutting quality, reliability, cost-effectiveness, and extended service life are the trademarks of the Pöttinger mower range.
