Kuhn Farm Machinery will be demonstrating its high capacity round bale wrapper, the RW 1810, at the Royal Welsh Grassland event at Four Crosses, Powys, on 16th May.
With a 30% faster cycle time compared to the previous RW 1800 round bale wrappers, plus features which include Kuhn’s Autoload capability, Intelliwrap system and optional 3D wrapping, the new RW 1810 can wrap up to 100 bales per hour with six layers of film on a 1.25m bale.
Two high speed satellite wrapping arms rotate at up to 40 rpm during wrapping (when driving at 5 kmh or faster) and apply 70% pre-stretch to the film as standard to produce a tightly bound bale. The amount of pre-stretch can also be reduced to 60% where necessary and the wrapper can be set to automatically stop or operate at half speed if one of the film rolls tears or runs out.
Kuhn’s Autoload facility enables the new machine to quickly, gently and automatically load, wrap and unload round bales of up to 1,400kg in weight and up to 160cm in diameter without any operator input and without the need for the tractor and baler to come to a standstill. This not only increases overall capacity, but also reduces fuel consumption and prevents operator fatigue.
The RW 1810 is an inline baler wrapper so can be operated behind a tractor or directly behind a baler.
Film application is controlled by Kuhn’s Intelliwrap system which allows the operator to select even and odd numbers of film layers to be applied by adjusting the film overlap to match crop quality and storage periods.
Kuhn’s optional 3D wrapping system, which uses pivoting pre-stretchers, can also be specified: this system packs a tighter bale by removing more air and ensures the edges of the bale are better protected by creating a 20cm overlap across this vulnerable zone. It also prevents rigid grass stems from puncturing the first layers of film by applying the film in the same direction that the bale is turning on the wrapping table.
The RW 1810 will be in action at the Royal Welsh Grassland Event alongside a wide variety ofKuhnmowers, mower conditioners, tedders, rakes, balers and baler-wrapper combinations. For more information visit www.royalwelshgrasslandevent.com
