Tridem chassis, 52.1 to 56.4 m³ load volume, 2 dosing rollers, from 210 hp

The forage transport trailer is the logical link for an efficient transport of quality feed between modern forage harvesters and the fodder silo. It maximizes utilization of the forage harvester, thereby paying a valuable contribution to reducing the time needed for harvest. As well as transporting grass and maize silage, the BERGMANN forage transport trailers can also be used for other forage, such as whole crop silage, wood chips and many other biomass products. The wide range of BERGMANN forage transport trailers has been developed for agricultural enterprises for which speed and economic efficiency are key. Rapid unloading and thus superior performance are ensured through the combination of a robust, conical cargo space, a scraper floor with four solid round-link steel chains with an overall breaking load of 100 t, and a powerful scraper floor drive on both sides. The HTW 65 S forage transport trailer has a load volume of 52.1 to 56.4 m³. Two standard dosing rollers are fitted for even, powerful milling of the loaded material. They can be unloaded in less than a minute. The standard tridem 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. A follow-up steering to minimize disturbance of the sensitive sward is standard. For the HTW series, many convenient optional extras are available, including a cargo space cover, forced steering, LED working lights and an automatic central lubrication system. It can be operated via ISOBUS.

Chassis:

High loads and service life through torsion-resistant chassis and low dead weight of forage transport trailer
High driving comfort through spring-loaded drawbar for low drawbar

Bogie:

High swing angles for good adaptability to terrain, easy driving over silos and easy towing with and handling on the road through tridem chassis with trailing arm and hydraulic axle compensation of 300 mm
Transport with low ground disturbance also at high payloads and low tyre wear through standard follow-up steering (1st and 3rd axle) and lift axle (1st axle)
High stability in the field and on the silo through 2,100 mm axle track width
Tyres up to 800/45 R30.5 for usability also under difficult conditions and low ground disturbance

Drive train:

Minimum wear through 1-piece shaft without spring pins and holes

Scraper floor:

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 drive pin skew through paired link elongation
Reliable crop transport through flights of rectangular tubing
Easy monitoring of scraper floor and chain tension through automatic chain tensioners that can be seen from the tractor
Convenient chain tension readjustment from the front of the forage transport trailer
Quick emptying through scraper floor that is mechanically driven on both sides with split feed shaft
Even power transmission to the scraper floor through mechanical drive
Even crop feed ensures a good distribution in the silo

Dosing unit:

Even, quick unloading also of damp and heavy forage through two dosing rollers
Good loosening of the crop through open, aggressive dosing rollers

A wide range of optional extras allows optimum adaptation to user requirements
