Rotary Cutter

The MK Tool Arm has been developed to provide an economical alternative for mowing road side ditches or along side fences. An 84" offset allows plenty of room to clear the tractor tires, as well as keeping the tractor on a more level surface.


Should you hit a solid object with the outer edge of the tool attached to the arm, we have shearbolt protection on a break away link.


With a 55 degree cutting angle with the cylinder extended and 90 degree cutting angle with the cylinder retracted the operator has lots of flexibility to match whatever terrain he/she is working with.
