Hay-making machine

An agricultural machine including a frame capable of being coupled to a tractor, said frame comprising hinge means and two frame beams which are respectively pivotal about a first pivot shaft and a second pivot shaft, an agricultural working member carried by one of said frame beams, said second pivot shaft extending substantially parallel to and spaced from said first pivot shaft, an intermediate arm connecting said two pivot shafts, said intermediate arm being free from agricultural working members;

• of the type intended for the agricultural machine.

A method of folding an agricultural machine comprising a frame on which is arranged a transversely extending group of working members, the method comprising folding part of said group of working members relative to the remaining part of said group of working members about an axis extending in the direction of travel the agricultural machine whereby the working width of the machine is reduced and then further folding said group of working members about a vertical axis whereby the working width of the agricultural machine is further reduced.

An agricultural machine including a frame capable of being coupled to a tractor, said frame comprising hinge means and a first frame beam and a second frame beam, at least at least one of said frame beams carrying a working member, said first frame beam being capable of being folded on said second frame beam by being pivoted about a pivot shaft located between said first frame beam, and said second frames beam a further pivot shaft being provided between said first frame beam, and said second frame beam said further pivot shaft being spaced a fixed distance from said first mentioned pivot shaft, said fixed distance being substantially less than the length of either of said first frame beam or said second frame beam, said first frame beam being pivoted about said further pivot shaft while being pivoted about said first mentioned pivot shaft, adjusting means for pivoting said first frame beam relative to said second frame beam, and stop means for limiting the pivoting of said first beam relative to said second beam to approximately one hundred, eighty degrees, said adjusting means being interconnected to said first frame beam via said stop means.

A hay-making machine comprising a frame, three groups of motor-driven working members arranged on said frame, said working members of said groups being rotatable about upwardly orientated shafts, each of said groups being operatively disposed transversely to the normal direction of forward travel of the machine, said groups comprising a central rear group and two outer groups which, viewed in the direction of travel, extend laterally one from each side of said central rear group, each of said outer groups comprising four working members, adjusting means for adjusting said working members into a transport position wherein at least one working member of an outer group is pivotable upwardly into a transport position about a substantially horizontal shaft extending substantially in the machine's normal direction of forward travel while each of said outer groups are pivotable in said direction about a vertical shaft whereby the width of the machine is reduced.
