    I just bought a extreme duty 72" CA brushcutter. It has the 3 blades sandwiched between 2- 3/8" thick plates. It is built heavy enough but the bolts that hold the 3 blades are actually welded to the bottom blade carrier. The nuts that hold the bolts are locked down in a hex on top blade carrier and cannot be turned.
    The only way to get the bolts out is to take a cut off wheel and cut the welds off and then turn bolts out. I dont like this design. The blades are made to cut in either direction without turning them over. The Radial Piston hydraulic motor will not reverse. It has a case drain. Are these style motors designed to reverse directions? I even tried to swap the hydraulic hoses with no luck.

    In the first pic it shows the hoses connected by what could a pressure relief valve so oil won't flow in reverse if you changed at the machine. Try changing the hoses on the motor and see if that works.

    You are probably right. I called the factory and that is what they told me to reverse lines at motor. I have not tried it yet. Only problem is when I reverse it the mulching teeth between the blades will be pointing the wrong way. I will reverse it at some point since the blades are gonna be such a job to remove.

    My CID cutter is the same way, when I changed blades I cut the welds off around the heads of the bolts and then backed them out with an impact.
    To change the direction of the cutter I flip the hoses and the pressure relief right before the hyd motor on the cutter.
