A special engine for a special machine

I've designed the ultimate yard mover out of it, but it needs a powerplanlt large enough to drive:

2 transaxles for dual rear axles

A hi/ lo TA that I built, which is just a small pulley on top of a big one, on the transaxle

A power steering pump or two that I'm using to provide auxilary hydraulics for a dump bed, three point hitch, dozer blade, and 2 remote outputs.

A belt drive air compressor, just large enough to fix a flat tire

Depending on gearing, and since I wouldnt use them all at the same time, would a 16 horse gas engine do?

The TA is of my own creation. The high gear is 2 pulleys with a 1:1 ratio, for speed when transporting empty. The low for work is a 2:1 or better, for serious power but not much speed. The 2 rear axles are basically to support the weight of a wooden dump bed and a small, home made gooseneck flatbed trailer. The very rear axle may not even be a driving axle, and if it is, it'll be a solid 1 1/2 rod, driven by 2 chains off of the factory axle. I'm going to convert everything to chain drive except the PTO, which will have to drive-

A tiny compressor, assuming that I can find one.

A power steering pump or two, but no more than two. I need one for a 3 pt, and one for remote, auxillary hydraulics.

Once I get my engine, I'm going to devise a dual vertical exhaust with Farmall Cub mufflers and rain cap, and a primitive exhust-powered engine braking. The engine braking will simply be a ball valve before the T for the dual exhaust, to make it work.

Dual enhaust will be a threaded pipe out of the exhaust, then a 90* elbow, and various fittings until I have a vertical stack on each side of the hood, mostly for looks and my basic engine braking.

Am I crazy, or does this thing have a fighting chance of working?

There was a couple 2 cylinder air cooled Deutz Diesels on ebay a while back. Might want to try those two and see what you come up with...

For my dump bed, I'm using the hand operated hydraulic unit off of an old pallet jack. If the situation warrants, I may wind up adding a second battery to supplement lights, and electric compressor out of a car's AC unit. After thinking it over, it'll stay belt drive from the engine to factory transaxle. To put the TA in high, I'll stop, and cut off the engine. Lock the clutch 'down' with the parking brake, and flip up the modified seat on modified mounts to reveal the top of the transaxle where the pulleys are. I'll take the belt and pull it off the largest pulley and move it up to the next one. Then, I'll adjust the pressure pulley I'll have to add so the belt will fit the smaller pulley snugly, and not slip as much. Sound like it will work?

I'll need one, maybe two power steering pumps. I cant decide if I want to put a 3 pt on the back, or a hitch I made myself. It works like a 2" reciever on a pickup, but instead of 2" square tubing, it's 1" electrical EMT conduit. This would give me a lot of options on the rear...but I could always make a drawbar for the 3 pt with this hitch...

My engine braking is a really neat feature, to me. I'm designing it because basically, I want this to have the hauling (and stopping) power of a lawnmower sized big rig, but be able to go anywhere. I'm also designing dual rear wheels, but eight 15 inch Ag tires would be quite an investment...
