I took my bush hog into the local dealer to have the blades removed and sharpened. I say removed because I couldn't remove the nut myself using a breaker and cheater. After about 20 minutes I stuck my head into the shop to check on his progress and found him under the bushhog sharpening the blades with them still attached. Ordinarily I'm fine with this but I also wanted him to remove the nuts, put some grease or anti-seize on the threads so I could remove them by hand if needed sometime down the road. I purchased this bush hog a few months ago, it's used, and it looks like the blades have not been off in years. I don't have a 3/4 impact which is what I think it would take to remove the nuts otherwise I would have done it myself. It's an AGCO Farmhand rc250 is that matters.
He said they don't normally remove the blades because the bolt and nut should be replaced every time they are removed, they are normally torqued at 1000ft/lbs and the bolts need to be driven out of the stump jumper which will eventually "wallow" out the holes. Does this sound right or was he trying to shoo me away?
