Side mower coupled with the tractor with three-point connection, second category. The primary transmission is made by a multiplier in an oil bath placed under the attack of the rudder. The cutting height adjustment is accomplished with the third point of the tractor. The cutting unit consists of a central swing suspension with a dual shock spring that allows a constant adjustment of the weight on the ground and allows to the drums to follow the soil profile for a clean cut. With the non-stop security system you can continue to cut also in case of impact without having to stop the tractor as the system allows the mower to move back and standing up to automatically hang up once past the obstacle. The mower is designed to be transported back to the tractor and horizontal to the ground with vertical folding (the latter on request) using an hydraulic jack. In both cases, the mower is in the shape of the tractor.
