Looked at a 8N...Cylinders honed and new rings installed. New valve seats and valves lapped. One thing I am not sure about is that he didnt have the crank turned. He installed bearings that were .030 over. Oil pressure was at 50 psi cold and dropped to 30 psi. After a bit of seat time and some bush hogging. Runs and starts good...Was asking 3700 with bush hog. He is down to 2700 bottom dollar without the bush hog. Did see one oil leak. Coming from the rear main seal. Cotter pin was in place and dripping oil. Compression checked out on all cylinders between 90 and a 110 psi....AMP guage was also showing a heavy charge.. Minor fix on that im sure. Has a 12 volt system. Fires up on half a crank...Opinions needed?

Here are my cheap cell phone pics...Has all new tin...Sand blasted the belly and was primed and painted..

Had he done a full rebuild and had the crank journals surfaced, I'd say it was a deal. Without that, it's more or less a "patch it up" overhaul. Not necessarily a bad thing, but I'd expect a little more tractor for almost 3 G's. Wouldn't be a bad deal if you got the hog. Nice looking tractor, but I think you could do a little better if you kept shopping.


What was the average price you came up with? I am thinking between 1500-2500. I got my 9N for 2500 included PHD, rear blade and a bush hog. Starts on half a crank. It was ugly but I fixed that..

the tempting thing is that its so close. Transportation would be next to nothing.

Sean and I went to check it out today. I think our pal Sean would have mowed all day long had there been enough grass to mow! the guy selling it started complaining that he was mowing everything for future customers to mow. I like that strategy Sean! LOL.
my question is what is a basic overhaul like that worth (new bearings, rings, and lapped valves)?


Nothing like free seat time. Plus that was my first ride on a 8N.

I spent $1100 on mine, including $180 on a 12V conversion, and I didn't do the valves (but I did replace the sleeves.) I didn't charge myself for labor.

Take 5 gallons of gas with you and bush hog in his pasture for an hour . I have learned more than once about buying something at full price that starts and looks good just to get it home and find that it crapped out shortly . I would rather lose $15 in gas than to spend $3k to find out that the liquid glass block sealer failed and spewed water through the fresh coat of paint that was hiding the crack.

Hobo,NC said: (quoted from post at 21:58:36 09/16/07) Its hard to say, the little devil must have caught you eye. By the pixs it looks better than my worker. At that price do you git the cab and air conditioner, does it have power steering. Any way to run a car-max report on it.

I don't understand the subject :Main Bearing replacement:, .030 is acceptable, .040 also, hill .060 if you can find'em


I know.. but most of the time dont you have the crank turned? I realize the bearings come in many oversizes. Its not 3700 anymore.. just the tractor and no bush hog...So the bottom dollar is 2700...

Bruce (VA) said: (quoted from post at 21:33:31 09/16/07) Oil or tranny fluid leak from the cotter pin? I'd be a little worried about 90psi on a cylinder after a rebuild, but for $2700, I think I'd get over it.
50 Tips


Engine oil was leaking. I also noticed the tranny is over full. The tranny oil is fresh... Not milky...No biggy on the overfull trannny just needs to be drained down...

Forgot to mention new steering wheel and gauges. Has a flip seat to. Wish I had one of those on my 9n...Brakes all on the right...That sure is a nice feature. Worked good too...

Lotsa times you don't get oil pressure up on a rebuild unless you also replace the pump, and also restore cam clearances, as it runs bare in the block.

however.. hot 30psi is pretty much big bragging rights unless the crank is rattling or galling..
