chinese tractors?

That's completely subjective. Has less to do with age of the iron, and more to do with the length of the tractor and the tire spacings.

My 50' JD-B trike will turn in-place with one brake stomped, and the front wheel on the steering pedistal turned full sideways.

Both my 8n and IH cub will also turn very tightly, again.. buy using r/l brakes I cammake a 1' inside circle with the inside rear tire onthe cub.. and about a 2' inside circle with the inside rear tire on my N.. mostly a function of length of the tractor for a 4 wheeled tractor.

My NH 1920 would turn on a locked rear tire, if it was in 4wd, and I stomped a single side brake. Of course, it was chewing up the grass in a 6' circle, and throwing rooster tails too.

Again.. very subjective..

The Jinma product line is somewhat redundant and overlapping which causes some confusion. Cant resist this opportunity to clear (muddy?) the waters a bit.

The JM184 and JM204 2 cylinder are basically the same tractor, with identical engines that are rated at different RPM to achieve different HP ratings.
There is a 22HP two cylinder which is not too common, this engine is also used in the 25HP 2 cylinder which is even more rare. Nearly all 25/28HP machines here use 3 cylinder Y385 engine by Yangdong

The 184 is the four wheel drive version of the tractor Farm Pro uses for their 2420 20HP. It is only slightly smaller frame and has smaller tires than the 25HP (which is the same as the JM284, except rpm at which HP is calculated, likewise with the JM304 or Farm Pro 2430 and JM354).

Anyway, the JM184 is a workhorse, and is undervalued on the market at present, IMHO. Parts are widely available for this engine (TY290) and it is and has been used by many Chinese tractor manufacturers. Going by memory, I believe this engine is rated at 14.7KW which is about 19.5HP at 2300 (I think?) RPM.

Remember that higher HP at a higher RPM may or may not mean more torque, and it is torque that you use.

The new JM224 is nearly the same as the JM254/284 except it uses a different (smaller) YangDong Y380 engine, this engine is also used in the JM204 20HP 3 cylinder (rpm ratings again).

Because of the 12 different gear ratios available on the "200 series" Jinmas (and thier various trade names), the tractor is capable of some pretty impressive work. Just look for some of the posts users of this tractor have made in the past.

Best to see, drive what you are going to buy before you do, if possible.

Soundguy, you are absolutely correct that it is subjective.

I was basing my statement on simple turning radius of a small Jinma versus something like a 50's Ford 8N or similar sized utility tractor. I did that simply because I interpreted the original question as one which posed that type of comparision. Now I can get fancy and do some brake turns and tear up our yards, but the lovely Mrs_Bob gets angry with me when I do that that. Or we can pick something like a tricycle Farmall 100 or Oliver RC77 (we have lots of those machines in these parts at reasonable prices) but I didn't think that was the question asked. Maybe I misinterpreted the question? But my answer was based on a non-brake turn of a 50's/60's utility tractor versus a 18hp modern Jinma.

googleeye:

one thing you said was to use a wood splitter on that I'm thinking you want to use the tractor hydraulics for the wood splitter ?? if so then you will have to do some modifying to the tractcor (JINMAS) to get the required rear remote hook ups. you're dealer can do this for you maybe? and get it right? maybe Not sure of the dealer and as for the agkings not heard of them the farm pros do not come with rear remotes and I do not think they will add them for you. they are a mass seller only who usually do not actually DO the requried repair work but they do provide parts very quickly form what I'm told... I use a JM284 (28hp 4 wheel drive.) the frampro s use soem different numbers and do other dealers NORTRAC (northern tool) also sells and usually services them as well... anyhwo if you have a local dealer selling them and he services then he would be best bet even if the price is a bit higher... remember these are inexpensive units with good power for doing work...

plowing snow you NEED the 4 wheel drive... I would pop for a FEL too as they are nearly indespensable.

( 50's/60's utility tractor versus a 18hp modern Jinma

It's still an apples to oranges comparison due to size. A utility tractor of the 50-60's era was a 27-40 hp tractor.. and sized accordingly.. with a wider stance and longer wheel base. That's not quite fair to compair it to a narrow, and shorter jm184. I recon my IH cub, without using brakes can make a tighter swing than a 184.. now we are compairing more the same size, width, and weight. In the end, the angle the front tires will rotate, the lenght of the wheelbase, the tire diameters, and the width of the tractor stance is what will dictate turn radious... and that will go for any non articulated 4 wheel machine.

As we both pointed out.. use of 4wd to assist in pulling the front around, or the use of steering brakes will tighten the turning radious considerably.

I see where you are coming from though..as poster asked for a comparison to a 50-60's antique...Hard to compair a small machine to a larger machine and still keep it all in perspective... especially for the tractor newbies that might be reading this, outside of the specific thread that started a few messages back. As you point out.. that antique iron was big, heavy, and very tough.. built to last, and when it wore out.. you could rebuild it in your barn with a hammer, torch, prybar, and a big set of sae wrenches. By the way.. I'm looking at an oliver 60 or 70.. and advice?

Soundguy I agree that comparing a Ford 8N & similar type machine to a small Jinma is not apples-to-apples, but that is the way I read the original poster's question, so that is what I did. I think many people make this comparision, probably because those machines are so commonly used on 5 to 10 acres for mowing and other duties, and probably because those machines are still very commonly found. Heck, you can get parts at NAPA auto stores so that obviously tells you that people still are using & fixing them. And the prices are even lower than the new Jinmas.

You might want to move to the midwest if you want an Oliver, you can still fall over them up here! The 60's are far less common sights, but the 70's and 77's are pretty common. There is a tricycle 77 about 2 miles away from me that is still used for mowing each week on a few acres. The lovely Mrs_Bob reminded me that I don't need to restore anything right now because the "honey do" list is full of half completed projects she'd like to see done, but I have been seriously looking at Cletracs and Oliver crawlers (up until she kaboshed that!). Anyway, if I was going to do an Oliver 60-70 series machine, the one I'd look for is an "orchard" machine with the full streamlined look that encloses the wheels and to some extent the operators area. They are pretty darn rare, but absolutely beautiful when restored.

But for me, the top of the wish list to restore right now is the Oliver HG, followed closely by a Cletrac HG --by the way DiskDr has one in restorable shape for sale that I was looking at!!! You might want to give it a look. Surface rust everywhere, some body panels missing, but it appears to be structurally sound.

About 40 miles south of me there is a guy with an oliver 60 or 70.. trike.. looks good. Decent price. Also hase tow cases.. ones a Dc.. and the others a VC or vac.. one is wide front.. the other is trike. Trike is rougher.. but I like it..wide front loks restored. All decent prices... but like you point out.. the little lady has nixed a 'restore/project' tractor since I just recently got a new lawnmower ( NH 7610s w/ 10' mower.. )..

Still nice to look though..
