My son jumped on the mower to move it out of the shed and the right control arm came off in his hand. Looks like the aluminum connector broke and the part ot bolt onto is broken too. The left side is cracked and proably needs to be replaced too. Looked up the part number that is on the broken part, and it is avalable from Amazon, along with the piece it bolts toas a set. I ordered a set for each side. Temps have headed into the 30's and colder so not sure when I will get it repaired, but at least I don't have to use it util spring(??) How does this get broken? I did get this from an auction used and I would guess th previous owner got a little rough with it?? Still love the machine even after the 2nd year of using it!!
