With preparations well under way for the silage season in many contractors’ yards, machinery manufacturers too are launching their latest innovations onto the market.
The tedder and rake market has seen a number of big launches over the last 12 months, especially as manufacturers try to match the high output of the foragers and balers that now follow them.
Claas introduced the Liner 3600 last year, with an adjustable working width up to 12.5 metres.
This four-rotor rake has each rotor equipped with a large four-wheel chassis. In addition, the contour wheels are positioned extremely close to the tines, so that the rotor can accurately follow ground contours.
In transit, the Liner 3600 is designed so that the height remains at less than four metres.
Claas also introduced their widest tedder to their current award winning Volto range.
The Volto 1300T is a 13-metre wide, 10-rotor trailed machine.
Each of the rotors is 1.5 metres wide and fitted with seven spreader arms with heavy-duty 10.5mm sprung steel tines.
In this award winning concept, spreader arms are angled by 29 degrees, instead of the spreading arms being straight.
Compared with conventional, straight spreading arms, the crop flow between the rotors has more space; this reduces the load on the driveline, reduces the bending forces on the tines, and is more gentle on the crop.
This robust, semi-mounted, trailed chassis machine is designed for transport speeds up to 50km/hr.
A novel headland management system automatically lifts and lowers the rear rotors on the headland, ensuring the swath ends are left neat and tidy.
The rake is designed to deliver a high work output, yet folds to a compact transport dimension of just 3.0m wide by 4.0m high, and 10.9m in length.
Each rotor is mounted on four pivoting, large-diameter wheels for excellent ground contouring.
This rake requires a minimum tractor pto power output of 115hp.
The Top 962C centre-swath rake has a working width of 8.9 to 9.6 metres and a large rotor diameter of 4.3 metres.
Mounting is straightforward, using a yoke that allows a turning angle of 73 degrees, and features a turning angle indicator.
The headstock is kept tidy, thanks to a practical PTO shaft holder and hydraulic hose boom.
The rotors are protected individually against overloading and a freewheel is integrated as standard into the splitter gearbox.
The Top 962C features a six-wheel chassis with tandem axles. The slant of the tines can be adjusted using offset bolts: the tines can be set around 1.5cm deeper towards the swath formation point.
The rotors with a diameter of 4.3 metres and 15 tine arms per rotor offer many advantages. The large diameter cam track without steep inclines ensures precise tine control and provides the tine arms with maximum strength and minimum stress on the arm bearings according to Pöttinger claims.
The cam track can be adjusted according to changing forage volumes and harvesting conditions.
The rotor gearbox unit is extremely rugged, with its gears submerged in semi-liquid grease and completely sealed to keep out dust.
Pöttinger indicates that the large diameter gear wheel guarantees smooth running and a long service life. The complete system is fully encapsulated and sealed to keep out dust.
The rotors are lowered hydraulically after folding for transport. Removing four of the tine arms brings the transport height to below 4 metres.
The rotors can be hydraulically shifted 60cm upwards if an obstacle is encountered.
The steered chassis with axle steering allows the rake follow the tractor exactly and helps the machine become extremely manoeuvrable.
The 2.9m wide chassis frame provides good stability even on slopes As standard, the Top 962C is supplied with 340/55-16 tyres, with 380/55-17 tyres available as an option. Large lights and fenders are standard equipment.
The straightforward hydraulic control system provides flexibility in the field.
The rotors are raised and folded using a single-acting hydraulic connection.
The lifting clearance at headlands can be adjusted and is limited by a valve.
The rotors can then be retracted using a double-acting remote valve, and the transport interlock then engages automatically.
Individual rotor lifting is available as an option, and this feature is activated using a button on the control terminal.
The working width can be adjusted using a double-acting spool valve and the swath width can be varied between 1.3 metres and 2.0 metres.
A display comfortably within the driver’s field of vision indicates the current working width as well as the height setting.
