In addition to finger wheel rakes, Sitrex also manufactures rotary rakes. The SR420/11H uses cam activated rake tines to pick up the hay and move it into the windrow. There are two benefits to using a rake with this type of raking action. The first is that the hay is handled very gently, and leaf loss is kept to a minimum. The second is that wet heavy hay can be handled with ease.
In some cases where a finger wheel rake may leave heavy hay behind, the rotary rake will make a clean sweep and have no trouble moving it. The windrow that is created with a rotary rake is generally considered to be the fastest drying windrow because it is fluffy and has plenty of gaps for air to circulate through. Raking with a rotary rake is usually slower than with a wheel rake, but for certain customers, a rotary rake is essential for a perfect raking job.
