Grey or Chinese?

[mark777]

rlee6,

I have not actually seen this, but have you heard of these tractors having such high porosity in their castings that they actually weep engine and hydraulic oils through the cases (and onto the ground)?

Having heard from reliable sources and other dealers that has happened, does that not support Tractor Ernie's statement concerning the strength and engineering aspects of tractors from China? Please understand that I am in no position to debate their quality, but asking you as a metallurgical engineer, does that indicate the quality of materials used in their manufacturing process?

Thanks, Mark

We used to see weeping cases. Ernie is correct that the metal in the Chinese tractors is defiantly different than what we see from Japan. I would say that some metallurgy is visible from the naked eye. Anybody that would like to see a Chinese transmission wide open is more than welcome to stop by anytime, I have quite a few to look at, and your welcome to take all the broken parts you like and test them.

Oil weeing through the wall of casting! That's bad. I was a foundryman once and know about casting. I wonder if they are more into capitalism (the ugly side) than us, I mean, for greater profit forsake quality. Or is it an innocent lack of knowledge?

My employer has several offices throughout the nation and I have visited most of them. Unfortunately, they don't have one in Washington. Otherwise, I would swing by your place and pick up some parts for analysis. It would be interesting.

<font color="blue"> China is sending rockets to the space and has atomic bombs. They must have the technologies of metal hardening, precision machining, etc, that they need to make good tractors. I don't know how much the technologies are employed by tractor companies. </font>

Like I said the chinese (the govt.) has the facilities to heat treat. not the tractor manufacturers.
Our govt. has the ability to do all that also, but not john deere!

I have seen the puddles under the Jinma tractors at Rural King farm store. I also had a customer looking at a Jinma that was at his neighbors . While the neighbor was turning in a tight circle , the front hub broke off and dropped the front end on the ground. Not urban legend.

I was at the National Farm Machinary Show in Louisville KY a few years back and looked at a Chinese tractor there that had a puddle of oil under it.

I looked at some Nortracs at Northern Tool and also saw puddles of oil under them.

I see puddles of oil under a lot of Harley Davidsons so whats up with that?? I have a chinese tractor and it works fine. Eveything has its problems. You's are all looking for a justification of why you own Japenese, Asian or whatever. You probably drive foreign cars also... Easy to slander what you never owned..Relax.....It's only a tractor...

I have owned 500+ Chinese tractors; I think that gives me the right to speak about them as much as anybody who might own 1 or 2. I still have a DF354 at my ranch. We are not saying you shouldn’t buy Chinese tractors we are just providing the real world experience with them that we were asked to provide.

Buck,
Isnt it funny how Harley hasnt produced a leaking bike for 20yrs, but folks always bring up the AMF years? /forums/images/graemlins/grin.gif
