there was a post on the tractor talk board where somone joked about putting a propelor on there pto shaft since they were having so much rain, well this got me to thinking,since an n series is relatively light weight,why couldnt ya make a nice pontoon boat that ya drive your tractor onto and park it in the middle,maybe a few chains to keep it from moving, and then hook up a pto shaft to run down to the propelor. seems like it might be handy if ya had an island or remote lake or river property where ya needed the tractor, ya could drive it onto the boat,power the boat out to wherever ya wanted to go,tie it off to shore,put out a few ramps and drive it off,do what ya needed to do and then load it back up and off ya go. maybe im just crazy,well thats what my co workers said when i mentioned this idea,but it seems like that could work

on this subject of a tractor in a boat, I think they did that on an episode of junk yard wars,, if I am not mistaken??? I think it may have been a farmall they used ,, but I may be wrong.I think they used the axles as paddle boat power,, but you copuld use a conveyer belt sort of contraption to turn the wheels like a tred mill,,, ok that was my 2 cents haha,, this place is great,,pat

I saw that episode, I thought the tractor was an old fordson?, but yep, they did do as you described, They positioned the tractorin the boat, and narrowed it so that the two rear hubs hung over the outside, and then they built some crude paddle wheels. Maybe there is still a pic on their website?

Use variable pitch screws like the Navy uses on its gas turbine ships. The reverse on a dime and give you change.

Once up on the pontoon platform, and the tractor secured, you could jack the front end an inch of fthe groun and have supports like jackstands hold it in place in combination with the chains.

Then use similar linkage as an air boats rudder setup,( front to back motion = right to left motion due to a rocker/pivot setup) only use it as the submerged rudder. Just connect up a small connection to the drag link on one side, and the steering wheel on your N now steers the pontoon... again not hard to setup...

Too bad one of us isn't rich... It would be neat to see this mocked up...

rich? i was just picturing finding like an old pontoon boat or even some barrels or even big plastic pipe maybe,i saw an old pontoon boat for sale a while back for 900 bucks, had a seized up outboard on it, the only thing holding me back is the lack of water to use it on. but maybe someday

This idea would allow you to pull a stump that was on the shore without fear of flipping the tractor on your head! But don't forget about safety. Always wear a flotation device (and ear protection)!

It certainly sounds like a possibility to me. Probably wouldn't be just real hard to set up either. That'd certainly turn some heads chuggin' into party cove with the big houseboats, sleek power boats with the big engines and wave runners etc. Could actually be a lot of fun. Let us know how it comes out when you get it done. Silly goose !! Later, Lee

Maybe you could leave the wheels hanging over the side and duct tape some paddles to them and call it a poor mans steam boat. Heck, with a Sherman step up transmission it might do 15 or 20 knots.

Could you make it go slow enough for roto-trolling?

At 2200 max rpms, I think I'd find another engine.

Could it be done? Don't see why not.

For a 24' pontoon boat (remember that the N's gonna take a bucha room) NOT including the additional 2400 lbs weight of the tractor (that's at least 12 people) would require a 25 hp (same's an N) 2-stroke outboard marine engine to develop all of 10 mph on flat water.

That 10 mph is at designed propeller speeds of 4000 - 5000 rpm.

So, you'd have to step down the PTO with a gear reduction by a factor of 8-9 WITHOUT a corresponding reduction in hp to the propeller WHILE running at full 2200 rpm N engine speed WITH only 10 gallons of gas AND you've already got the equivalent of a boat load of passengers in weight given the weight of the N.

THEN, you've gotta figure out how to STEER the rig! Simple rudders take away hp. Efficient way is to have the propeller turn the rig. Not possible as described in the post. HAVE to use simple rudder.

So, I figure ya MIGHT get about 3-4 MPH max outta this idea.

You could use one of the new triple toon boats designed for an inboard/outboard and install a gearbox in place of the (boat) engine. You could then use the original steering and shift controls mounted off to the side of the tractor. Wouldn't be very efficient but sure would be a big smile!

Uh...

Does that formula take into account the size of the prop...Angle and number of the blades...???

There were many many small (18-30 foot) steam operated boats on the great lakes etc that had nowhere near a prop speed of 540 that could do close to 10 knots...Aren't the old one lunger lobster boats still operating at way less rpm?

Lookin' at Mercury specs as an example. In pontoon boat applications. Remember, as a general rule, larger props = more hp required. Doubt more'n a 16" prop is useable given the N-as-stepped-down specs.

As for the steamboats, look at the length of the throws of their drive-connecting rods and, as you mention, the size/angle of those props (assuming you mean true props and not the paddle wheel type). The steam engine system (not talking about steam turbines now) is a low rpm set-up and HAS to use the physics of trading lever length (throws) for speed. Same as with the old trains. The piston throw was fairly long in order to handle the power requirements.

Another example, but in the gasoline engine arena is oil well pump engines like Wisconsins. Very low rpm, but that long crank generates some great power.

theres no reason ya couldnt turn the propeler if ya had a universal joint or a cv joint, im not talkin about putting the prop right on the pto shaft, ya would have to use a driveshaft like that on a brushog or a bailer.

I wasn't assuming a propellermounted right to the PTO. I can't figure out how you steer a propeller with a cv or u-joint either. Can you elaborate how you'd connect to PTO, prop, and what sort of steering connections and controls you'd use?

What would the engine RPM have to do with hooking a 540 PTO to a prop?

You could even have the prop driven through a reduction gear setup...But installed backwards...Have the 540 PTO rpm drive the prop at 2000 RPM...Or just put a REALLY big prop on it...

yea i would think a medium sized prop turning at 540 would be enough to propel it along at a decent speed,and like salmoneye said, it could be geared up too, with a chain drive or something like that im not talking about making a speedboat to waterski behind,just something that would be nice for a cruise on the lake, or to get the tractor to a remote place accesible by water,unfourtanatly i dont have a place near a lake but i thought it was an interesting concept,sure would look neat from a distance too, it would look like ya were driving your little N series ford across the water.
