I replaced the bearings on one side of the mower deck. All 4 of the bolts broke off, I knew they would because when you put steel bolts into an aluminum housing, they always break off. I pre heated them but they would not come out. All 4 broke. I am good enough that I was able to drill them out instead of having to buy another housing!!! The mower is a good mower but I have to replace 4 more #6204 bearings and an idler pulley. Send me the parts free so I dont have to drive 30 miles to get them. Or send me 2 bearing housings.
