Hidrot Optima 5.5-6 Fractional arm mower for tractor rear linkage
 

 


The HIDROT Optima arm mower is hinged on the rear II. category 3-point linkage which is braced and also mounted on the tractor’s undercarriage.

The 3-point linkage and the support rods form a torsion frame which holds the mower structure by the means of two thightening chocks. Due to the equipment design it can be fitted and put down without the help of a specified workshop. Either the mover head and the arm structure is powered by a hidraulic pump section which is driven by a cardan with the minimum of 1000 min-1 shaft revolution. The mower head can be controlled from the tractor cabin.

The arm control is performed by a two-way joystick with electro-hidraulical actuating. The ground following and the arm raising is done electrohidraulically and the obstacle avoidance against hidraulic force with the turning of the arm.
The working adapter is a horizontal axle flailmower with special heads knives and a work width of 1000 or 1300 mm.The mower head is protected against stone throwing with rubber panels in the front and a rubber carpet at the back.
Many other Hidrot adapters can be mounted on the arm ending.
