Rototilling w/8N ?

Thanks,

Now, if you took a set of iron wheels on an axel connected to a hitch with some sort of spikes or grippers on them. You might add wheel weights to the wheels for added traction.

You could mount a three speed transmission kind of like Chevy used from the 50's through the 80's. The transmission would provide a gear reduction for the PTO speed of about 3 to 1.

The trans output shaft would be connected to a gear box with two axels out the side with a small gear on each end. A bigger gear would be on each of the two iron wheels connected to the smaller gears with a chain. This would provide a great deal of gear reduction speed to move the tractor.

Behind the hitch iron wheels would be a standard three point hitch tiller. The tiller would have to be raised and lowered with a hydraulic cylinder independent of the drive wheels. You would also need an extra set of wheels to raise and lower the entire unit like they use on a big disc. The tiller unit would be pulled around like a trailer when being transported.

The drawbar hitch that the unit attaches to would have to be solid so the tiller could not push it up while tilling.

You would also need another PTO shaft that would run from the front of the add on trans back to the tiller so it would run straight off the PTO.

So what do you think about this concept. The tiller would do the tilling. The iron drive wheels would do the very slow driving from the PTO. The tractor would be operated in neutral while tilling.

By the time you got yer claptraption jurryrigged, ya could have bought a real rototillin tractor.

And by the way, the TroyBuilt rototiller has powered wheel drive, I gotts one.

Trust me, if'n ya just gotta rototill, N's arn't the machine..... .....Dell

Behind the tractor, either in a trailoring fashion or by three point hitch connection would be a drive axel fitted with two wheels possibly about the diameter of the front wheels of the tractor and fitted with some type of small spikes for traction. The wheels would be driven off the PTO through a car transmission for speed reduction. The car transmission would only be connected to the auxiliary drive axel and would not affect the design or normal operation or speed of the PTO going to the tiller.

The tractor's transmission would be placed in neutral during the tillers operation and the tractor would be driven by the auxiliary set of wheels positioned just behind the tractor and riding on the ground. The drive wheels may have to be fitted with wheel weights for added traction.

The car transmission, when placed in first gear for example, would provide a certain amount of gear reduction going to the aux drive axel. Also with a small gear of lets say 2 inches at the end of each axel running down to another gear of lets say 6 inches at each wheel connected with chains would provide a great deal of speed reduction for the aux drive axel.

If the input shaft of the transmission was turning at 540 rpm, the output shaft would turn about three times slower, add to that the small gear to large gear connected with chains going to the wheels and the tractor would just creep along.

Understand that the forward movement of the tractor would be provided by the aux drive wheels behind the tractor and not by the tractor's transmission.

Where the PTO shaft goes into the car trans for the aux drive wheels, there would be another shaft positioned just above it and driven by a chain which would provide standard 540 PTO speed going just to the tiller.

Any standard three point hitch tiller could be connected to and behind the aux drive wheels and the tiller would not be modified in any way. The tiller would be raised and lowered independently of the aux drive wheels.

You may still disagree with my thinking, but I think Troy-built would understand.

Anytime ya start muckin around with power transmission, ya gotta make certain everything is in alignment.

Repeat after me, rototillers require 1000 rpm pto and 1 1/2 mph ground speed. N's just don't supply that, period.

If'n ya don't believe me, go down to your local tractor dealer and talk to 'em about a NEW TRACTOR, don't even mention yer N-tractor. Have'em explain the finer points of their new tractor as a rototiller machine. Make like yer innna the market. Get some brochures and study 'em.

Then if'n yer still interested in using yer N-tractor as a rototiller machine, rig up a 25 hp aircooled aux engine to a 5' rototiller and drag the aux engined rototiller behind yer N. DO NOT USE YOUR PTO Sure be a whole lot simpler and eazier than your proposed kludge..... ..respectfully, Dell

Your mileage may vary

Remember, the N-Tractor was designed to replace the farmers horse team at plowin time. This was before rototillers were invented. Theres alotta things that were invented after the N's 3-point hydraulic lift design proved itself and then you discover certain "deficencys" and sometimes you can engineer around 'em like the need for an OverRunning Coupler on the PTO to prevent that big brushog from back driving thru your tranny when you clutch.

Sometimes the cost of solution is greater than a different answer to the problem. Thats where we're at with rototillers and N-Tractors. The N's pto turns at too slow rpm and the rear wheels turn too fast. A lotta better minds have pondered your quest for a N-able rototiller answer. I gave the answer, the rare and fragile Howard aux tranny that is NLA.

Back in the 70's, I saw several 3-point rototillers with aircooled engines driving the tines. You just mounted 'em to your N's 3-point and pulled it thru the ground behind you. I don't remember anything more about them.

Bottom line, as neat and useful as the N-Tractor is, it is NOT a rototiller machine. If'n ya just gotta rototill, then get a diffferent tractor, you'll be much happier..... ....Dell

N's are NOT rototilling machines. PERIOD!!!
N's are great 2-bottom plowing fools.

Heres the deal, they're too High geared, even with the dealer installed optional Sherman aux trannys. 'Cuz they also slow down the PTO drive thru the main tranny.

Unless you can find a rare and fragile "Howard" aux tranny that mounts behind the main tranny and slows down just the differential drive.

Unfortunately, there are no Howard tranny parts available anymore, that I know about, unless you make a journey to jolley ol'England, home of the original Howard company, ya never knows what kinda antiques you can find overthere.

Sorry for the bad news..... .....Dell
