I bought the AGT-RC72 new on a local auction sale and put to work right away.
Mounted on a CAT skid steer.
The work lasted 30 minutes and the gearbox seized. Sure, I should have checked the gearbox for oil, but since I found no sticker "fill oil before use" I never thought about it. New gearbox was suppose to be USD650 plus shipping. So we fixed what we had. Needed one bearing & one oil seal, CAD$80 and we where going again.
I mowed 1000 yard and hit a rock and busted one knife. USD187 plus shipping across the border plus taxes CAD280 total about.
I continued my work two weeks later and found one more rock: two knifes gone plus the knife arm bend & broken.
Now the unit gets a three blade setup with a center disk rather then the arm and we will see.
Not the rugged unit I thought it would be.
