An implement for displacing crop lying on the ground comprising at least one rake member which is driven so as to be rotatable about an upwardly orientated axis and which is provided with a plurality of outwardly extending arms, each of which pivots in upward direction about a pivot axis. Each arm has a pair of outwardly extending tines connected pivotably thereto. The pivotal connections of the arms to the rake wheels and the tines to the arms of each assemble of arms and tines is such that the center of gravity, when the implement is operating, is so disposed that the resultant of the gravitational and centrifugal forces urge the arms and the tines towards the underlying ground. The rake wheels can be folded upwardly about their pivot axes into a transport position wherein the arms are received in a locking device which comprises a resilient member having a recess for receiving each arm. The resilient member may comprise a spring or be composed of an elastic material such as plastic or rubber. The pair of tines are pivoted downwardly while in the transport position.

Rotary hayraking implement for uneven terrains

A hay-making machine comprising motor-driven working members which rotate about upwardly orientated shafts. The working members are divided into three groups arranged in rows extending transversely to the direction of travel of the machine. A central group is at the rear of the machine and two outboard groups extend outwardly from a location forward of the central rear group in such a manner that the inner working member of each outboard group overlaps (as seen in the direction of travel) the outer working member of the central rear group. The machine includes a frame on which the three groups of working members are mounted. Each group includes four working members. The outer two working members of the outboard groups are foldable to a position over the two inner working members of each of these groups about horizontal axes. Then the outboard groups, as so folded, can be pivoted about vertical axes so that they are positioned along side the frame. The outer working members of the central rear group can be pivoted about horizontal axes extending in the direction of travel of the machine by ninety degrees whereby the machine, in its transport position, is less than about three meters in width compared to its working width of about twelve meters in width.

Hay-making machine

A mowing machine comprising a mowing unit, a crushing member and an adjusting mechanism, by means of which one or more crushing parameters can be adjusted. At least one sensor is provided, by means of which the extent to which the crushing member is loaded during operation is recorded. This sensor also supplies one or more control signals to the above-mentioned adjusting mechanism to obtain automatic adjustment of the machine's crushing parameters. The adjusting mechanism can adjust the relative positions of the crushing member and the mowing unit, the rpm of the crushing member and the size of the crop channel, among other things.
