ABSTRACT TOOLHOLDER FOR USE IN A ROTARY CROP-CUTTING MACHINE A toolholder for use in a rotary crop-cutting machine, such as a mowing or chopping machine, comprises a ro- tatable tool carrier, to which the tools are adapted to be pivoted on pins, which are parallel to the axis of rotation of the tool carrier. Each of said pins carries at least one tool and at opposite ends is radially slidably mounted in axially aligned slots, which extend radially with respect to the axis of rotation and are formed in two axially spaced apart lugs, which are secured to and substantially radially protrude from the body of the tool carrier, or in two axially spaced apart disks, which constitute the tool carrier. Each of said slots has a radially outer portion for retaining the associated pin against axial displacement in said radially outer portion. In order to ensure that a detaching of the tools will reliably be prevented even if the lugs or disks are very thin, each of the two axially spaced apart and axially aligned slots of each pair has a constricted radially outer portion, each end por- tion of each pin has a diameter that corresponds to the un- constricted width of the slot, the constriction is defined merely by project10ns, which are formed on the side faces of each slot on that side which is nearer to the other slot of the same pair, and the pins are formed with recessed portions for receiving said projections.
