Holy smokes, that things huge! How much do you think it weighs? What id do is run the stock grill, and get a big sheet of sheet metal and bend it up/cut it up around the engine so it pokes through, and you wont be cutting the stock hood up. Ive sold stock hoods before for a little bit too.

Yea Its very big and its only 7.5hp! Im guessing it weighs about 150+lbs but I think im just gonna cut the hood and put a hood scoop over the hole so it looks good it will save me the time

Nice, I need one of those for my next project.

What a sears or the engine?

The engine. I need a small diesel with electric start to run two alternators and on occasion an air compressor. That one might be kind of big, not sure. It needs to fit into a 30" diameter tube with at least some extra space to get it in and out. I've heard of that lombardini name. I was going to use one of those yanmar clones like fearless front used for his tractor. I'll have to look around I guess. Small diesels are expensive.

yes this engine is great it starts and runs well its 7.5 hp so should be good for your project I happened to have one of these arrow boards because my family owns a construction company but you can pic up one of these engines for $375 on ebay its alot cheaper then the 10hp clones but bigger and most of them have oil sumps

Just a little update on the tractor and the engine. About 2 weeks ago we found out the starter was good and just needed to be regrounded. Then we painted the starter flat black changed the oil and oil filter so we dont have to worry about that later. As of right now the motor being bolted down to the tractor and we are seeing how it looks with the hood on. I should have some pictures tomorrow.

Nice engine! I think my 6hp is in around 70lbs, not too bad, still heavy though.

Ok here is a quick update I braised the fuel return for the electric pump and put the fuel exit also got a alternator just like fearlessfront and made a gas pedal our of construction rebar and maybe will weld a foot peg to it

Was the gas tank originally under the seat?
Im trying to figure out how it should go on the one I have, a ss16 I believe.

No it was under the hood like the other sears suburbans are this one is a st16 not an ss16 the ss16's have the gas tank under the seat but if it did I would have moved it for lights and a rack but thats my opinion.

This thing is going to be a monster! I cant wait to see it rolling. It'll definitely turn heads.

Thanks I sure hope it gets some peoples attention I am planning on bringing it to a tractor fair in july

Ok so it may look like not much is being done but its doing great I got the alternator mounted I romoved the rust from the gas tank and fluched it with diesel fuel I got the grill gas tank straps and grill mesh painted and we got the pulley but we took it back off for a little bit.

Got tires! 25 inch super swamper vampires for the rear and 16 inch X-tracs for the front both very great tires the X-tracs on my super 12 have served me great and I cant wait to try out the vampires on the rear definitely the crazyist atv tires I have seen and owned in my life I know there is better ones out there but I think these are going to preform awesome! and I painted the gas tank.

Nice! What's that alternator from? Looks like a fairly small one.

Its a bi-directional alternator from amazon its the same one fearless front mounted on his tractor

Well this week is probably been the best week yet for the build stuff is finally getting done on this thing a ignition and kill switch has been installed, the throttle is almost done just a few more bolts, the motor itself is also bolted down now and I will be trimming the mounting plate I painted the mounting plate and part of the frame black for now then later when I tear it back down to paint it I will repaint it green. I got a battery and did most of the wiring then did a test start to make sure everything worked and there was success!! Now I am attacking the exaust I am going to be installing a curved hood stack instead of a slash cut one because I dont want smoke in my face So I would really appreciate if you guys would let me know if you like the exaust or not thanks.

I would consider something else since youll have to cut the hood to make that work. Id try making a side exhaust that exits by the floorboard so the smoke is under you not roght beside you. But thats a personal opinion.

Thanks for the opinion I think I am still going to keep the stack though worst comes to worst I can Just take it off make a different exaust and put an intake snorkel where the hole was

Its starting to take shape intake is finished and the exhaust is being worked on now also I have decided to not do the turbo because my dads mechanics that are helping me build this tractor said there really is no reason to put one on an engine this small and it wouldn't run right so I took there advice and threw a hi-flo intake that came off of a 300hp twin turbo Mitsubishi car and I think it looks sick!

Looking very good, i agree with the turbo, a lot of work for not to much pay off really. Looks like it fits in there better than i thought. Engine pulley should net you some good speed and crawling still in first gear.
