If you just need to turn over a windrow, the Sitrex RP2 rake may be all that you need. This rake has a very simple design, basically a three-point hitch bracket, an extension pipe, and two rake wheels mounted on a tandem rake wheel arm. The main purpose of this rake is to turn a windrow for drying.
However, the rake does utilize full size 55" diameter raking wheels, with 7mm tines and taper bearing hubs, and it will pick up the hay cleanly from the ground. Raking width maxes out at around 6-1/2', so if you have more than a few acres, you should consider something larger. Note also that this rake cannot be reconfigured to spread out a windrow like the larger RP4 and RP5 wheel rakes.
