Toolholder for use in a rotary crop-cutting machine

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