Tractor Performance: diesel vs gas

[Soundguy]

The one I saw back in the late 90's was an actual tractor.. not a lawn mower.. I don't have the model number though.. If I had to guess it was perhaps a lil larger than a NH TC-18 frame size.. though maybee like a tc 21??.. anyway.. that size of machine.. was 2wd, with regular tractor ag tires int he back..e tc.. kind about the size of a jinma 25hp machine..e tc..

And just for asking a question??

Maybe for asking on too many? All I know is that it really helps keep the conflict down when you don't see the other persons posts!

Yep it would John. It would also insure that one doesn't have to look at any other opinions or ideas that one may not agree with.

You should go back and read the thread more carefully!

Injector pumps have a longer life cycle than a carb,

I have an issue with this statement, there are maybe 4 moving parts in a carb, choke, butterfly, needle, float. 99% of the time you can rebuild a carb without any gaskets if you are careful, if you are not, it's $2 for a gasket, $3 for a needle. Ocassionally a float that springs a leak.

Little water, dirt in a carb, just blow it out, in an injection pump, it'll waste it. It's a lot more complicated.

Are you not confusing the fuel with the new emissions systems that regenerate themselves by using fuel to burn off accumulated soot?
I may be mistaken, but I think it is the engines that are less fuel efficient by virtue of their new anti-pollution devices, not the ULSD fuel itself.

I think realistically you have to put the 2 together. You can 't buy a new truck without the new emissions on it. And if you remove them, you might not get it inspected. And from I understand, tractors and other things will follow as the EPA expands the ULSD rules on diesel engines. Probably some sort of hp range, weight, etc.

the carburetor and points, are the two things that I miss the least about old gas engines.

Make sure you put the old in BOLD here. point went away a long time ago for most engines. I have an old 1974 Merc 9.8, electronic ignition. HEI ignitions came out in GM cars around 74-75 I think.

Funny how parts for a 50yo tractor or Jeep are real easy to come by.

That is the year I bought my Power Trac PT425, which is also gas, although not a "real" tractor, but still outworks any diesel tractor of the same size and weight except in plowing dirt, which I do not do.

Ut oh, gasser outworking any diesel tractor.....

to some thems is fight-n words!!

Cub still had a gasser in 2001 I believe. That is the year I bought my Power Trac PT425, which is also gas, although not a "real" tractor, but still outworks any diesel tractor of the same size and weight except in plowing dirt, which I do not do.

From Wikipedia: A tractor is a vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction.

So how is a PT-425 not a real tractor? What else would you call it?

It's not large, and it's not conventional, but it is certainly a tractor.

Awe shucks.. lets not interject any reality into this opinion based thread now!

( Takes 10 seconds to solder a pinhole in a float..) I'm not sure what aprt of an injector pump I can solder to fix?? )

Conventional seems to fit. It's kind of a crossover from light industrial to agricultural...
