Re: rear axle suspension in the next 8R series?
Quote:As soon as you have a rear suspension the rear hitch will suspended, whether it is the Deere suspension or the JCB suspension
No. On the JCB, the hitch is mounted on the rear axle, which is not suspended. The complete frame is suspended toward the rear axle, but there is no suspension at all between the ground and the rear axle housing / hitch contrary to the JD design.
Quote:New Holland also had a prototype T8000 with rear suspension at Agritechnica in 2007. Suprinsingly there is no picture to be found of the suspension system online. Although I remember seeing one close up which showed that it looked pretty similar to Deere's.
True, NH did present a suspension in Europe, but it never went to customer's fields. From what I heard, it was not very advanced in term of dynamic behavior. On the Deere, they made a big work on the cinematic to keep the draft force effectless on the suspension heigth.
Quote:i'm possive it's very nice for the driver. but like said: not for the equipment behind! in stead of the jcb, the machinery in the hitch will be smooth suspended as well, but how many trailed equipment is designed for >20 mph?? The europe tri-axle trailers may be. Anyone knows?
In Europe, it is not an issue to find trailers for high speed applications. You can get a lot of them 25MPH ready, and now you get more and more for 37.5MPH.
Even on the 25MPH version, it is more and more common to have hydraulic or pneumatic suspension. At least, you get brakes on every trailer, whatever the speed it is planned for.
