Ijust purchased my first tractor, an 8n in good shape. Today I tried to rotavate a plowed field and managed but it was difficult.Does anyone think that a 5' rotavator is too large for this tractor? First gear seems a little too fast for travelling.

I never owned a 8N or rotavated with one, BUT i do a lot of custom rotavateing. I own (3) Howard rotavators at this time. Maybe this doesn't apply, but the "real" problem here is power! Most think you need a very slow ground speed to rotavate, but the truth is you need a FAST tine speed so you can go faster!! The problem with that is, it takes a LOT more pto power as you turn the tine speed up!

A rotavator will work well in "any" soil!! You just have to set up the rotavator for those conditions!! As i do custom rotavateing, i run into all kinds of soil from blow sand, glacial silt, gravel, mud, hard packed clay and everything inbetween!!! It's all in knowing what your customer wants/needs!!

Bottom line is, you need more power!!

Larry..... ...every springtime the YT N-Board gets this same question "Why can't I rototill with my N-Tractor", and the answer is always the same, the N-Tractor is too HIGH SPEED ground geared (as you found out). Unless you can find the rare and fragle "Howard" after tranny aux gearbox $$$ yer outta luck. The more common dealer installed "Sherman" aux trannys slowdown the PTO rpms too much.

Howsomevers, the 8N is a 2-bottom plowing fool, its just not a fool about rototillin'

Remember the rototiller was invented AFTER the N-Tractor was designed and was designed for ENGLISH soil conditions to be used with the Ferguson TE-30. (equiv to 8N). Remember, its the 1939 Ford/Fersuson System that set the cat-1 3-point standards, now used world wide..... ...Dell

Though I bow to your knowledge of Ford Ns etc and value yor advise greatly a thought just popped into my mind.Could the ground speed differential involved here be solved with perhaps a smaller set of rear tires wheels,used specifically for rototiller appl.For years we have flipped/reversed/reset the track for different tasks such as cultivation.It seems that it would be no harder to switch out a set of 16-20" or so rims with suitable size rubber for this task as maximum traction/flotation is not the issue,but simply carrying/operating the tiller.
Your thoughts please.

Dell,info on what I'm thinkin here is prolly out there in Nland,What were the gearxgear groundspeeds on regular Ns vs the BNO-25/40 Tug models with truck size rear wheels/tires?,Must be in print somewheres,ya think?

Joe..... ....I am under the impression that the millitary aircraft tug versions (BNO-25 & BNO-40) of the 2N Ford Tractor used the same 6.66:1 differential pinion and ring gears. Which rummor has was off the 1 1/2T Ford medium duty truck. The BNO's rear brakes were hydraulic operated, while the tractor and Ford automobiles were mechanical brake operated. The BNO-25 used a single rear tire and the BNO-40 used dual rear tires. Both used small diameter front tires, not tractor based tires. Large diameter tires are used for ruff-offroad applications, runways are usually preety smoothe.

Rummor also has it that they actually shipped back to the States, alotta aircraft tugs that were then re-converted to agriculture tractors. And they dumped good airplanes and jeeps into the ocean, go figger..... .....Dell

What Im gettin at looks like this,at 2000rpm engine speed if top gear was 1:1 into a 6:66 differential a 40"(overall)tire would equate to appx 35mph groundspeed.Given all factors the same vehicle with a 30"(overall)tire would be at appx 26mph,regardless of tread design or wheel size.For instance I believe WillyN is running some 16"rim Ag "floaters" on one of his tractors,though overall tire height is similar to the original size.With the vast number of sizes/styles/profiles of tires/rims available these days,it might pay to experiment a bit.However,like swapping cycle sprockets(same idea)a trade off is made ie speed lessens power,power lessens speed.Just wish I had a Sherman hi/lo N and owned a tire shop...lol,Somewhat scary is the fact that a Sherman hi N with taller(ie 50" tires)should clock close to 50mph IF you had enough engine torque to get em up to speed and "big brass ones".

Joe..... ...understand where your coming from. Might work with the 8N's smaller 11" brakes but would definately NOT work with the 2N/9N's larger 14" brakes. Somewhere I seem to remember the Howard after tranny had about a 4:1 reduction. So you'd need to get a rear tire/rim combo that would reduce your 8N ground speed by a factor of about 4 as compared to the OEM 10-28. Might be do-able if'n you was inclined to 'spiriment.

Of course there is this other direction to consider. Back in 70's, down around Lodi Calif, used to see N-Tractors draggin' an air cooled AUX ENGINEED 3-point mounted rototiller thru the grape vines. Don't know 'nuttin' more. Make of rototiller, nuttin'. Could have been a local machine shop fabrication, I wasn't interested at the time..... ....Dell

Thanks for all the advise guys, but it makes sense that someone said that these 8n's never had a rotavater attachment. So I'll experiment with speeds or go back to square one and plow, disc and harrow.
