Jinma 184

[trentay]

Michael and John,

This is one of those positive occassions when it is nice to say I told ya so!!!! /forums/images/graemlins/wink.gif

That weight and torque thing really makes a difference. Wish I knew what the real HP of this tractor is at least in terms that we could put some useful value in. What I do know is that the 2 cyl produces very good torque and the the weight of the machine is easily determined at the local scale, thus its ability as a tractor when doing work. I sure wish I could get more people to understand this, but everyone is so darned concerned about the HP rating that it overshadows all other factors of usefulness.

Michael, glad you are having fun with the machine, it really is a sleeper in the tractor market isn't it?

I know this thread is rather dated, however, I just read it, and have a suggestion that you find a speed shop or similar shop that has a dynamometer to measure the HP of your Jinmas. It really is a simple thing to do, as is the weighing at the local scale. I'm not sure, but I think most fairly large cities have at least one engine/speedometer shop with a dynamometer. I hope someone will do this and post the results. I happen to have bought a new Kioti CK20HST, but am still considering picking up a Jinma for other work. Thanks, John

I'd say you were told wrong. The TY290 engine is rated at 13.24 kw, which computes to 18 engine horsepower. I'd estimate that puts less than 15 hp at the PTO. Add that to a working weight of 2200 pounds, and a category 0 hitch - I don't think you'll find it suitable for your current implements.

It's one of the reasons I'm getting rid of my JM254; the 104 to 1 weight to horsepower ratio. I'm staying Chinese for the cost advantage - but like Tim Taylor, I need more POWER. Looking at a 40 horse KAMA this weekend.

The frustration comes from trying to work 30 acres of steep hillside pasture and woods. Too much of that 25 Jinma horsepower is chewed up just dragging it's own 2600+ pounds around, much less spinning a 500 pound mower or dragging a 400 pound spike tooth harrow - uphill. The power to weight ratio is further aggravated by an extra wide gear ratio spacing in a (non-synchro) 3 speed transmission. I don't consider it suitable for working hilly ground, with any speed and efficiency that is.

By comparison, my Yanmar has a 67 to 1 weight to horsepower ration and a much closer gear ratio pattern in a 4 speed (non-synchro) transmission. Unfortuately it's a 2wd turf tire machine, and has pretty much been relegated to fair weather work.

Don't get me wrong. These Jinmas are definitely workhorses, but you've got to buy the right tool for the job. I didn't pick the right one. So if you've got flat ground, and are willing to buy smaller implements.....
