We have two Kubota RTV 900's with 4 way hydraulic Curtis snowplows. I came home from plowing for the city to find one of the plows my wife uses hanging off the front of the machine by just the chain, I took a look at it and found it cracked on both sides at the front of what I call the A frame, I figured she must have hit something pretty hard, until I looked at the other rtv Curtis plow and found it had a hair line crack on both sides, but had not yet completely broken. It appears to be a weak spot, it is hollow and made out of box steel all the way till this point where they cracked. I have added some pictures so you can check yours. I know the welds are far from perfect but it did the job to get us through the storm.
