The present invention relates to a compression spring assembly for a hay rake. The compression spring assembly has a rod that slidably receives a first stop, a compression spring, and a second stop. A limiter assembly is connected to the rod and has a limiting member that is received through a guide of a guide assembly that is connected to the rod. The guide encompasses the limiting member.

The agricultural raking machine comprises a frame configured to be towed by a towing vehicle, at least a raking group assembled on the frame and provided with rotating comb-like elements apt to move material mowed onto the ground to form a windrow, and flotation means associated to the raking group and to the frame, the configuration being so that, at variations in height from the ground, the raking group raises/lowers with respect to said frame.
