I am sure it can be pulled butttt be advised. If you have a 160 cu inch engine in it if you wreck somthing internally things are more expensive for those engines, 149 engines are easier to find. if it were mine I would at least pull the valve cover and go from there to insure least amount of damage.

I am in Iron River . there are a couple small AC tractors where this one is. one has what looks like industrial cast iron wheel centers (kind of like bar bell weights totaly different from the farm one) and the brakes are hand levers on each side. I will get pics of them. the second one is a farm type with a wide front, slightly toasted. the farm one had a starter the ind. one didn't even have a place for it. from the engine forward is missing on the ind. but it has some kind of a three point setup left on it. I am off to Eagle River today. I work for the radio stations in Iron River and Eagle River, so I am over there thur. and fri. I am waiting for them to deliver my new toy. When I went to ask if I could have the keys to the tilt bed they offered to deliver it. About 25 years back the owner and I took his John Deere dozer to pick up an in floor hoist. when we were loading to go home, as I was lowereing the bed back down to the truck with him and the dozer on it. (a lot more weight than we normally hauled with it.) he was yelling something to me. (he had to keep the dozer backing up to aid the winch in pulling it up the ramp.) so I stopped the hyd tilt to see what he wanted. what he wanted was to tell me not to stop the tilt once we were on the way down. we busted a bunch of attaching bolts on the trucks tilt mounts. funny the things that stick in your mind. I think the 2010 JD was heavier than the H3. but it still easier for his guy to bring it. It's just when.

If you would consider selling the pto I would be interested

Nice to see another Yooper on here. If you can get some pictures that would be great. I'm always interested in A/C equipment.

I'd do it with the starter ajd battery. As said, take it apart a little and see whats up. Should be the 149 cid motor. Parts are available and not to pricey. That motor is real simple.

Hi had this all written and the computer ate it. I am still waiting for it to appear here at home. if it isn't here by the time i get off of the air Sat. I am going to see if one of my Buddy's at the recyclers where the H3 is, can give it a tug with a loader, to see if we can get her to turn. I tried the starter before I pulled it, and I tried a bar against the ring gear through the starter hole. no go. I looked and felt the front pulley, I don't feel a nut or bolt. just holes around the face of it. maybe I can make a drive of some sort to try and turn it from the front. as far as the PTO I have to wait and see where this goes. I don't see me using it. but it also looks like project to remove with the shifter and all.

thanks

Jeff

before tugging on it and forcing the motor to turn I would pull the spark plugs and put a mixture of ATF and Acetone down the holes. This will help loosen stuck rings (Vs breaking them by forcing the motor to turn over). I would also pull the valve cover and make sure the valves aren't rusted up.

You might as well pull the head at this point. If you couldn't turn it a little prying against ring gear you got trouble. Safer and cheaper to pull the head and fix the problem at hand. HTH Tracy Martin

The ATF and acitone works great on stuck motors. The longer is soaks, the better!!!!

Hi it soaked since wed today I got one of the guys to push it with the big loader. the goos news all the clutches work. the bad news it's still stuck. no sense hammering it so I will wait till it gets here and pull the head. any recommendations on how to unstick it without popping the sleeves up. and if they come up can i put them back. or am i asking for a coolant leak

thanks

Largeonee: welcome to the H-3 club, sweet little machines. Craig Cannon an AC Tractor Engineer did a nice job designing the machine.

Largeonee, Did you get your motor free'd up? I've just gone through the same problem on the same machine so i'm just curious how yours ended up.

Hi

and Merry Christmas

I don't know where fall went. I had meant to update on the project, but once I got it running , I spent every spare minute running it.

I had to pull the head on the H3. when I did I was pleased with it's condition. very little rust, no ridge. I honed what I could of the cylinders. I am a Jeep (40's n 50's) guy so I have a lot of home made special tools for them. one of them is what I call a cyl knocker. One of my Buddy's used to run the flame/plasma table at a local shop, so I got him to cut me some (hockey pucks) discs out of thick steel. they are slightly smaller than jeep pistons. He took it farther by having one of the welders weld a huge chunk of square stock onto one of them. we free engines up by dropping it onto the piston top and smacking it with a bfh. it spreads the blow around to the whole piston top. doesn't always work, but most of the time it will free them up. The H3 piston is a lot bigger around but i tryed it anyway. the engine came loose and I was able to turn it with the fan after only a short time. I thought I was on my way but the starter was shot. I found an armature and fixed that. I had discovered in the tear down that two of the rocker arm supports were busted. They want $50 each for them. I was going to try and weld them when I found a larger AC tractor in the scrap pile and robbed it of it's supports. they were taller so I cut two of them off, and used them. at first the engine had almost no compression and didn't want to start. once I got it started it smoothed out nicely. I have gone through about 20 gal of gas, and it runs a very long time on 5 gal. another hundred or so, and I might be able to make a flat spot ha ha. I went out a couple weeks back and started it up. It took right off, and I plowed snow with it. my wife thought i was nuts. she asked why I was using a bull dozer to plow 6 inches of snow? I told her cause I can. anyway this is the greatest little tractor I have enjoyed every minute and I look forward to next summer.

thanks

Jeff
