The SHUTTLE 390 K is a loader wagon with a load volume from 37 to 39 m³ and is designed for combined use for green fodder harvest and as forage transport trailer. The 2,270 mm wide pick-up with double swath roller facilitates a clean crop intake. BERGMANN is the only manufacturer to offer both a steered "ActiveLoad" and a non-steered "EasyLoad" pick-up for loader wagons. This allows users to choose the pick-up type that is best suited to their particular requirements and operating conditions. The rotor with a width of 1,840 mm and a diameter of 850 mm is designed for a high throughput with perfect cut quality. With the short cutting unit with 53 knives, the theoretical cut length is 34 mm. The scraper floor is made of rugged steel (standard equipment) and lowered by 275 mm at the front for a better material flow and lower power demand. The SHUTTLE has a movable front wall to increase the load volume and a forage loading flap for use as forage transport trailer as standard equipment. The standard tandem chassis with 300 mm hydraulic axle compensation ensures superior driving characteristics, excellent stability and off-road capability as well as safety both at standstill and while driving. To ensure low ground disturbance on the field, various tyres in sizes up to 800/45 R30.5 are available. Superior user friendliness and high ease of use with ISOBUS operation as standard. The ISOBUS standard allows the use of ISOBUS-compatible operator and tractor terminals.

• Chassis:
• High loads and long service life through torsion-resistant chassis and low dead loader wagon weight
• Easy coupling through hydraulically operated high-lift drawbar for low drawbar
• Narrow drawbar for good manoeuvrability
• Stable when parked through manual folding jack stand
• Bogie:
• High swing angles for good adaptability to terrain, easy driving over silos and easy towing with and handling on the road through tandem chassis with trailing arms and hydraulic axle compensation of 300 mm
• Clean mudguards and therefore no soiling of road since mudguards are tapered to the outside
• Manoeuvrability, transport with low ground disturbance also at high payloads and low tyre wear through standard follow-up steering
• High stability in the field and on the silo through 2,100 mm axle track width
• Brake system:
• Safe driving, operational safety and high ease of use through standard dual-circuit air brake system
• PTO shaft:
• Overload protection for tractor and loader wagon through standard wide-angle PTO shaft (on one side) with cam clutch
• Intake:
• Clean fodder collection without loss, also of short fodder, through steered pick-up with 2,270 mm intake width
• Suitable for wide swaths
• Double swath roller for ideal material flow even at high driving speeds
• Infinite speed adjustment of pick-up via hydraulic drive
• Rotor:
• Optimum cut and load rate through 1-rotor system with wide cutting rotor (1,840 mm, 850 mm diameter)
• Ideal material flow through very small taper from the pick-up into the cutting groove
• Maximum throughput possible at large width
• Optimum loading of cargo space also at the sides
• Maintenance-free main drive, transmission via powerful planetary gearbox
• Low wear through Hardox tine coating
• Cutting unit:
• Short cut fodder with a theoretical cut length of 34 mm for good compaction in the silo through 53 knives on one level
• Easy and exact cutting for high fodder quality
• Knife shape and position of rotor tines ensure a pulling cut
• Optimum protection, reliable and smooth retraction of knives into the cutting groove through separate foreign-object protection for each knife
• Tool-less and therefore quick and easy removal of individual knives for maintenance or knife change
• Body:
• Easy change of loading method from loader wagon to forage transport trailer through stable body without diagonal brackets and ropes
• No accumulation of crop and reduction of friction forces thanks to a rigid contoured panel body with hydraulically movable hinged front wall and smooth insides and side walls in the front section
• High transport capacity despite compact vehicle size and quick emptying through hydraulically operated, hinged front wall
• Good visibility into body during filling and emptying through large viewing window in the front wall
• Easy harvesting through standard forage loading flap in the front wall
• Reliable mechanical locking of hydraulically operated tailgate also on poor roads
• Optional auto-loading with two measuring points, adjustable from tractor for rapid adaptation to changing operating conditions
• Scraper floor:
• Loading with low force and good product distribution right from the start of loading through short conveying channel and 275 mm scraper floor inclination towards the front
• Long durability and high reserves through four strong round-link steel chains with specially hardened ends
• No chain skipping due to large engagement depth of chain links in the chain sprockets (approx. 95 %)
• No flight skew through paired link elongation
• Reliable crop transport through flights of rectangular tubing
• Easy checking of scraper floor and chain tension through automatic chain tensioner
• Readjusting of chain tension at front under the loader wagon in the area of the cutting unit
• Quick emptying through scraper floor that is hydraulically driven on both sides with feed and return line and high-gear 2-speed control
• Even crop feed ensures a good distribution in the silo
• Operation:
• Easy and safe operation allows high daily output
• High ease of use through ISOBUS operation as standard
• High-lift drawbar and knife bar can additionally be operated from the left side (in driving direction) of the loader wagon for easy coupling or maintenance work
