Swath formation: the benefit of double-curved arms
The homogeneous quality and volume of windrows are conditions for fast drying and easy pick-up by balers.
The tine arms on GA rakes are in hyper-tangential position. This means that they reach a 90¡ angle very late. With the tines' sharp-angled cam, tine clearance is quick, later and requires little rotational effort to produce regular, fluffy and straight windrows. Raking is of high quality even at high speeds because the forage is not pushed past the windrow.
The advantages of double-curved arms:
- They reduce the distance between tine passes. Forage loss is reduced to a minimum, even at high speeds.
- The main weight is at the centre of the tine arm. This increases service life as it is not subject to pressure during rotation and the guide rollers are less subject to stress.
