i bought this 8n this year and never used it until this last weekend. it did a good job. three months ago when i bought it, i got a rear blade and a brush hog. have not used the hog yet but the blade did good at helping me make a road where the wife and i are going to make a house. 1st prob. the three point hitch is all bent it works but i would like a new one even the grease Zerk is broke off on the thing that makes the one side go up and down. is there a place i can get all the parts and save a little money over getting separate pieces? also i changed the oil and filter when i got it, it needed it done. the old owner said he just changed the hydro fluid but when i make the rear go up it goes up but the last few inches it goes grrrr and goes slow. it will only stay up for 15 min if i turn the engine off. 2nd prob. i need new front tires they are rotten. the back looks good. should i get the three ridge or the single ridge? the single seems to be hard on the grass. 3rd prob. i would like to clean the tractor up and put some paint on her. can i just use a wire brush on a drill and get the paint off and prime and paint with the spray cans of paint i bought from tractor store?
