How does an 1949 Ford 8N compare in horsepower to the JD4100 (gear 4x4)? I am actually wondering how implements for the 8N stack up vs the new tractor.. I have seen specs that gave the 8N 18 to 23 HP at the drawbar (which converts to 26 to 33 engine HP i believe), I have also seen specs that gave it 18 at the PTO and 23 engine. So I am not sure which rating is more accurate.. I know the 4100 is 20 HP engine and 17 PTO HP.. How much would 4x4 help handling implements even if the HP is less than the 8N. Could the 4100 pull a one bottom plow? How big of a bushhog can the 8N handle?I am also studying the specs of the JD 790 and Kub L2600, but feel that they will certainly outpull the 8N due to more HP and 4x4. I like the other tractors better, but the price on the 4100 keeps dropping (last weeks paper advertised it for $9495) so that weighs in also.Thanks for the help...

I'm not sure how this is a fair comparison. In terms of fitting a wide range of implements, I think the 8N wins. The 4100 is narrow, which means your available space to fit 3pt hook-ups is narrow as well. I've run into this problem when using old implements. As far as traction, 4100 wins by a slim margin. 4wd's traction advantage goes without saying, but you have to have the HP to match. The 8N properly weighted could probably outpull the 4100. The only real advantage of "handling" implements in 4wd is (1). 4wd by nature is heavier in the front than a 2wd. (2). 4wd ties your front and rear wheels to the rear brakes. This provides an obvious braking advantage on wet hills, etc.. over 2wd alone. If you consider traction as part of handling, then yes to that as well.
Although I haven't pulled a one bottom with my 4100, I think it could do it, but don't be surprised if you need to make two passes to sink the shear deep. ....

Thanks for taking time to reply... I have a couple follow-up questions for you... What can you do if the implement is too wide for the 4100? Can you invert the attachment points to make it narrow enough? I've seen the 'pins' on the inside of a bushhog frame, but i just thought it hadnt been assemblied correctly.
Do you have to purchase special 'narrow' implements for the 4100? Or is most of the newer stuff made to fit the compacts better than older implements? If i would go with the 4100, i would hope to be able to use some of my dads implements.
Do you ever wish you had gotten something bigger like the 790 or Kubota L25/2600? I think the 4100 would do what I will ask of it, but hate to regret a major purchase decision shortly thereafter just to save a thousand dollars or so..
Thanks for the input.. ....

I have a JD4100 and I think that I can answer most of your questions about this unit, but I don't know anything about the Ford 8N, except that they were made before I was born. I have pulled both a 12" and 14" one bottom plow with my 4100. No problem in dry, compacted garden soil. I haven't tried breaking new ground, but I bet if the soil was somewhat moist you would have no problem. I also have a subsoiler (ripper) that I use before plowing to really rip it deep. The secret to plowing with this unit is: go slow, use 4wd, and use about 200 lbs. of front end weight. I also have a Woods brand 52" rototiller, a 5' rear blade (which I snow plow with), a dirt scoop and a 54" mid-mount mower deck. People I know who use a rotary cutter (bushhog)with this unit have a 4'cutter. The 4' cutter seems to work great in tough conditions, and most people say that a 5' model would work too if you don't try to cut too large of material. The same thing goes for a box scraper unit. The 4' works great and the 5' unit works if you don't take too big of bite. This tractor really has plenty of power to handle most any chore, AS LONG AS YOU USE THE PROPER SIZE IMPLEMENT FOR THE TRACTOR. One last note about the 3 point hitch arms -I have only once encountered the problem mentioned about the arms being too narrow. This was on my dirt scoop and I just reversed the pins like someone else mentioned. I think that most implements today have fairly standard hitch hook-ups, compared to some of the older implements. This tractor is a great small acreage homeowner or landscaping unit. It is a good compromise between manuverability and power. A local rental yard rents this unit with loader and box scraper, and he told me that it is more popular than his larger units due to compact size and manuverability. However, if your needs are regularly using it to bushhog or plow large acreage, or full-time construction backhoe/loader work then you would be happier buying a larger tractor. ....

I forgot to mention that tire style plays a role in the available width. Originally I had the R4's which I mounted in the "wide" position. My current turfs do not provide this feature. Well..I guess they could be off-set if you don't plan to use wheel weights. (They won't fit) As far as implement selection, most smaller compacts will require you to reverse the pins. The 4100 is no exception. Only one time was I faced with an old,old implement that I couldn't use because of 3pt hook-up width. This is only an issue if you intend or plan to use your neighbors stuff...like myself. If you will only be using implements you purchase...not a problem. Second issue when borrowing stuff, is that your neighbors might have bigger tractors, thus bigger implements. In my case, I used a 6' blade on my 4100. Obviously this is a bit much for the tractor, but a little patience and extra care & caution allowed me to do what I needed. AS far as overall size...Look in the archives for my whiney post in which I complain about my 4100 not being enough for a 2 acre property!! I guess I'm one of those guys who expects his lawn mower to be on par with a farm tractor..But thats another story. Next time I think I would seriously look at a Kubota 2910. Basically the same package size, with more beef stuffed in the middle. Lastly, the 4100 is plenty narrow for traversing hills. ....
