I have 19hp 42 inch CC. in the last few weeks the idlers are cratering. First the thru bolt fractured, replaced worked for several cuts then the other the bearing disintegrated. Those 2 idlers m were part of repair kit with blades and spindles from Stens. Do they make a more durable idler. I do know that I,m asking more of this mower than designed for rocks branches dirt hump but thats my rural setting.. Why would the idlers have anything to do with the rough terain> Help if you can Thanks
