KUHN GA 7631 - 9531 Semi-mounted Gyrorakes
GA 7631, GA 8131, GA 8731+ and GA 9531+ semi-mounted rakes stand out from competing models by their robustness, reliability, and ground following capacity. With working widths of 7.50 to 9.30 m, work output is high while ground contouring remains excellent. The MASTERDRIVE GIII rotor-drive system, makes these rakes effective in difficult conditions. You can form uniform and airy windrows that are easier to pick up by the harvesting tool that follows.
Features & Benefits
The homogeneous quality and volume of the swath are conditions for fast drying and easy pick-up by the following baler. The tine arms on GA rakes are in hyper-tangential position. This means that they reach a 90-degree 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 swaths. Raking is of high quality even at high speeds because the forage is not pushed past the swath.
- To pass over swaths without damaging them, GA 8731+ and GA 9531+ rakes feature a suitably high headland turn position. In addition, the rotors can be tilted individually up to 40 degrees with more than 75 cm of clearance possible if required. So, there's no need to worry about formed swaths when you pass over them.
- The KGA 04C facilitates manoeuvres. You can easily place the rake in work/transport position, set the raking height hydraulically and raise the rotors individually.
- In transport position, the exclusive STABILIFT system of the GA 8731+ and GA 9531+ locks the rotors hydraulically. The machine is considerably more stable on bumpy roads and when passing over windrows. The transport height of the GA 7631, GA 8131, and GA 8731+ is less than 4.00 m, without having to remove tine arms. Concerning the GA 9531+, only 3 tine arms need to be removed per rotor.
