1 PZ Drum mowers PZ series GRASS HARVESTING AT ITS BEST!

2 PZ DRUM MOWERS KUHN PZ DRUM MOWERS Shrewd farmers have known for a long time that maximum yield and profitability can only be achieved from top quality hay and silage. This is truer now than ever before. Mowing plays a vital role in the grass harvesting process. Timing is of the essence and mowing must be done when grass is at its optimum maturity. Huge areas must also be mown in the shortest time possible so that the crop dries evenly and the best use is made of short weather windows. For more than 45 years, PZ has stood for stability and ease of handling. You really can rely on a KUHN drum mower. It is no wonder that the KUHN PZ drum mower is setting standards for cutting quality and ground contour following in the market place. The KUHN PZ mower incorporates the technology required to meet the expectations of the most discerning farmer KUHN can provide you with mowing solutions to take into accounts your requirements in terms of: Cost reduction Good practice

4 PZ FOR A CLEAN CUT 2FDrum+mowers%2FPZ+280+F&twg_show= jpg v PZ series drum mower - 45 years of experience! The new generation of KUHN drum mowers has been developed using a combination of experience and the most up-to-date mowing quality, technology and design engineering. The result is a complete series of front and rear drum mower units. The well-known features of the KUHN PZ drum mowers have been complimented by new solutions such as the FLEXPROTECT protective side covers and its modular structure. 3 Flat sided drums Round drums do not transport. KUHN uses drums with two flat sides for optimal crop transport without the risk of blockage. The drum and drum skirt are two detachable parts which greatly facilitates maintenance and repairs. Screw-on transport strips Movement of the crop has an impact on mowing quality. It is for this reason that KUHN has chosen to use screw-on transport strips. Rotating saucers The continuously rotating saucers have a major advantage. In uneven ground conditions, the saucer rotates over the ground rather than sliding, thus protecting the stubble. The positive effects of reduced crop contamination will be particularly noticeable on sensitive soils such as boggy land. Quick change blades Using the special blade tool, you can push the blade holder down and simply replace the blades. A quick and efficient system! FLEXPROTECT Damage to the side covers is now a thing of the past. The KUHN FlexProtect side covers are adding a new dimension to mowing with their design made of polythene. On encountering any obstacles, the material of the side cover gives, without breaking or damaging the mower. The material then returns back to its original shape.

5 PZ As reliable and economical as the big mowers twg_show= jpg age.php?twg_album=kuhn%2fdrum+mowers%2fpz+280+f&twg_show= jpg PZ 170 / PZ 190 v High output With the three models of drum mower, PZ 170, PZ 190 and PZ 220, KUHN provides high-quality technology and working widths from 1.65 to 2.10 m. These KUHN drum mowers are suitable for small to medium-sized farms, and its long-life, easy and safe operation are key attributes. The PZ 220 can be retrofitted with a conditioner which can be removed without tools thanks to a special centre section and practical quicklocking mechanisms. 4 Safety break back system On hitting an obstacle, the mower unit pivots back, thus absorbing the impact. Reversing the tractor re-engages the safety system, and the mower unit is set back into work position. Easy hitching The PZ 170 and 190 can be hitched easily to every tractor with Cat. I or II linkage pins. KUHN can provide a special adapter for tractors with wide tyres. Compensation springs Compensation springs are fitted as standard to transfer the weight from the mower unit to the tractor in order to keep ground pressure as low as possible. Working position Using a cord, you can move the mower from transport position to working position and vice-versa. On the PZ 220, this can be done from the tractor cab. A hydraulic folding cylinder is available as an option.

6 PZ Uncompromising set-up for professional use v The PZ 270 and 300 models have a tried and tested drum design with over 15,000 units sold. Large outer drums and small inner drums mean benefits such as perfect ground contour following, clean swath formation and large throughput. Wide spreading A wide spreading kit is available as an option. You can use it to mow and spread the crop widely, all in one step. 5 3-point linkage The adjustable 3-point linkage enables you to shift the machine to the left or right. When using the front and rear mower units in combination, this ensures that overlap is always at its optimum even when cornering. Headland cylinder The optional headland cylinder offers comfort in a large extend and gives the PZ 300 sufficient ground clearance under any conditions. Easy access to the drums The front cover can be folded away, allowing easy access to the blades. This is perfect for daily inspections and mower maintenance. Safety break back system Both mower units have a safety break back system for optimum drum protection when meeting obstacles in the field. On hitting an obstacle, the mower unit pivots back and absorb the impact. Reversing the tractor re-engages the safety system, and the mower unit is set back into work position. Transport You do not have to leave the tractor seat to swivel the PZ mower units easily and conveniently into transport position behind the tractor. A hydraulic cylinder is available as optional equipment to fold the machine up vertically behind the tractor

7 PZ 310 A FAction&twg_show= jpg Trailed drum mower v The KUHN PZ 310 A offers an easy-to-operate trailed mower unit with a 3 m working width. With a trailed machine, you do not require a tractor with high lifting capacity. The PZ 310 A requires a minimum of 60 kw (80 hp). Optional extras for this machine are: a conditioner covering the whole width and a wide spreading kit which can deposit the crop across the whole mowing width. 6 Hitches The KUHN PZ 310 A can be easily and quickly hitched to the tractor. The wide angle PTO shaft allows you to make sharp turns to the left or right. If you require an even tighter turning radius, you should choose the swivel hitch version (i.e. with GYRODINE ). Stubble protection Weight is distributed via two torsion springs which are connected via a rod, thus ensuring that contact pressure always remains constant across the whole width of the machine and stubble is protected. Along with the freely rotating saucers, this ensures perfect ground contour following. Transport and working position With the double-acting drawbar cylinder, you can move the machine from the transport to the working position and vice-versa. The cylinder allows you to drive smoothly around obstacles. With a lifting cylinder on each wheel, you can lift the mower unit. The lift height is 40 cm, which means that there is always enough ground clearance, whether on the road or the headland. The GYRODINE variant is hooked onto the lower links. The PTO drive shaft always remains in a straight line with the input gear, as the gear can be rotated. You can use the slewing gear to achieve a steering angle of 90.

8 PZ 270 F F - TC 310 KUHN frount mounted drum mowers high performance 7 v With the PZ 270 F and PZ 300 F models, KUHN sets the standard in this class. The drum arrangement, FLEXPROTECT side protection and accessibility have yet to meet their equal. The mower unit attachment with two large outer drums and two small inner drums ensures maximum throughput for the forage. In this way, you can deposit a double swath that can be easily picked up by any following machine. Using the generously dimensioned swath discs, the finest of adjustments can be made: Narrow swath (90 cm) for dayto-day gathering of forage from sloping terrain, wide swath for hay. TC 310 If you wish to use your mower unit for day-to-day gathering, but also want the possibility to use a conditioner for silage or hay harvesting, then the KUHN TC 310 is the solution. Hitch the TC 310 to the rear to condition the fodder and deposit it across the whole mowing width. Foldable front cover The foldable front protective cover on the PZ 270 F and PZ 300 F can be lifted upwards - convenient for daily inspection and blade exchange. Optimum ground adaptation The fixed headstock provides a good, well-priced solution for all grassland specialists. The flexible Flextop top link connection and Frontflex telescopic top link ensure unique ground adaptation in the driving direction. Traverse ground adaptation is ensured by the front linkage arms. For tractor lifts without pendulum device, a pendulum PENDELFLEX headstock (P) can be supplied if required.

9 8 Cutting height adjustment The cutting height is adjusted using a spindle at the top of the mower. This can be easily reached and infinitely adjusted. You now no longer need to crawl under the mower to check whether cutting height is evenly adjusted from left to right. Clean swath formation Using large outer drums and small inner drums has benefits: perfect ground adaptation, clean swath formation and high throughput. Fixed headstock + Frontflex PENDELFLEX pendulum headstock

10 PZ 900 Easy towing and high output v If you want to mow wide working widths, the PZ 900 is the right mower combination for you. With its two mower units, mowing up to a width of 8.50 m and upwards of 74 kw/100 hp is possible with the PZ 900 front and rear combination. Farms with tractors in the 74 to 110 kw/ hp range can now achieve maximum mowing width, and therefore the highest work rates. 9 Simply impressive: the PZ 900 front and rear combination The two rear units of the mower combination are built from a tried and proven design.. With the legendary drum design of more than 15,000 front and rear mounted mowers so far sold; these mower units have proven themselves in real, tough operating conditions. One special feature is its arrangement of mower drums: Large outer drums and small inner drums produce a swath form to match intake, follow the contours of the land perfectly. The freely rotating saucers make this mower very easy to tow. Adjustable working width and overlap The working width of the mower units can be set to one of three levels: 7.94 m, 8.20 m and 8.50 m. One of the advantages of this is that you can use front mower units of different working widths, which in turn means that you can increase the overlap in hilly conditions. 7,94 m 8,2 m 8,5 m For a road transport width of less than 3.00 m, the mower units are swung upwards using hydraulic cylinders. Three different working widths.

11 With the help of an attachment kit for the frount mounted mower (special equipment), the PZ 900 can be used as a reverse drive combination. 10 Compact design for best weight transfer The PZ 900 has a weight of 1800 kg. With one frount mounted mower and two mowers attached to the rear of the tractor, this mower combination ensures an excellent weight transfer for best manoeuvrability in sloping terrain. Safety break back system The PZ 900 is fitted as standard with a hydraulic safety break back system. On hitting an obstacle, the mower units move upwards and backwards, independently of each other. This hydraulic safety break back system also controls the ground pressure hydro pneumatically. Independent lifting The PZ 900 drum mower rear combination is also available with an optional hydraulic single lift.
