Description
With the new JUMBO you are always two steps ahead.
The JUMBO is a high-performance loader wagon that delivers maximum output, high efficiency, excellent reliability and the best operator convenience. It guarantees enjoyable work and high yields. The new range brings you safely through the harvesting season and is also ideal for transporting goods of all kinds at other times too.
Advantages
Belt Drive
Power transfer reinvented
The innovative, unique drive concept has been designed for tractors rated from 200 to 500 Hp. This means that the JUMBO can be operated with a wide range of tractors.
The driveline has a double wide-angle PTO shaft without a clutch and is powered by a Powerband. Optimum power transmission to the rotor is ensured by angular/planetary gears in the rotor drive.
The Powerband delivers maximum power transfer in all operating conditions. It ensures smooth running and a damping effect in changing operating conditions. This protects the mechanics and reduces maintenance and wear costs to a minimum.
Special overload protection system
A PTO shaft with an overload protection system is subjected to extreme wear-intensive stress when used in high-performance harvesting equipment. The angle of the PTO shaft during operation produces torsional vibrations which prematurely trigger the overload protection system and negatively impact throughput.
PÖTTINGER therefore decided to remove the overload protection from the PTO shaft and integrate it directly in a fixed position in front of the angular/planetary gearbox.
Thanks to the newly developed drive concept the JUMBO can be continually operated at up to 3000 Nm. The result is optimum protection of all drive components against unnecessary stress and wear-intensive blockages.
Irregular swaths can be picked up with no reduction in speed and no losses, even when cornering. This increases loading efficiency enormously.
Cutting unit
JUMBO 7000 with a chopped length of 34 mm
With the proven POWERCUT short-chop chopping system, a JUMBO 7000 series is the ideal solution for highest throughputs with low power requirements and the best chopping quality.
The 48 knives are arranged asymmetrically to the rotor tines for clean and tidy chopping action and are individually protected against foreign objects. These enable a chopped length of 34 mm.
The knife bank that swings out to the side and the hydraulic, central knife release at the touch of a button, are standard equipment on the JUMBO and ensure quick handling without the need for tools.
In addition, the fully automatic AUTOCUT knife sharpening system can be added to ensure that the knives remain sharp for a precise cut at all times.
On the JUMBO 7000, TWIN BLADE knives are available as an option instead of single blade knives.
Pick-Up
Neat, safe and convenient
The JUMBO’s wide pick-up combines clean and tidy collection without losses in a single pass with a supremely comfortable ride. It is suspended in the centre and controlled from both ends by a steel cam track. The enormous pick-up width of 2.3 mm according to DIN means that no swath is too wide. Thanks to the extremely high loading performance even swaths intended for a self-propelled harvester are cleanly picked up.
The large working width also makes driving into the swath and cornering easier, which takes the pressure off the driver.
Perfect ground tracking
Regardless of the terrain in which you use your JUMBO, the floating pick-up adapts perfectly to the ground contours and protects the crop against contamination.
Hydraulic adjustable weight alleviation reduces pressure on the ground to approx. 100 kg, allowing the pick-up to float over the ground.
The optional pick-up jockey wheel chassis with floating function features a patented parallel linkage for unique ground tracking.
Rotor
It simply moves more
The heart of the JUMBO series is robust, powerful and designed for almost unlimited tractor power. The rotor and its innovative driveline provide high throughput, perfect chopping quality and, if required, the highest possible compaction.
Thanks to the wide, edged areas at the 12 or 10 mm tine tips on the 8-row rotor, it takes over the crop actively and reliably from the pick-up, even if the crop is wet and short. The rotor tines are arranged in a helix formation, with a diameter of 850 mm to guide the forage smoothly through the 34 or 25 mm short-chop knife bank. The rotor is mounted directly on the chopping system frame in order to protect the rotor drive as much as possible even under heavy load.
A tine form that has been optimised still further, combined with the largest possible scraper surface in the loading chamber, makes compaction of over 400 kg/m³ possible if required.
Driveline
The rotor is powered by angular/planetary gears which lower the high PTO speed to the ideal rotor speed. On the JUMBO range with beater driveline, the forward-mounted angular gearbox also features a through shaft and an integrated switch.
When the beater driveline is activated, the maintenance-free clutch engages, the drive belt starts softy and unloading begins.
The components are protected and a long service life guaranteed.
