Tractor Performance: diesel vs gas

[MossRoad]

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.

I'd call it a tool platform. Most folks consider tractors to be small front tires, big rears, pullin' a plow, etc.... farmer stuff. You and I know the benefits and weaknesses of the Power Tracs. Much better than a conventional tractor for the stuff we need it to do, much worse than a conventional tractor for plowing dirt and pulling stuff, etc...

I pull (non-ground engaging) stuff with mine all the time, instead of using my CUT. It pulls my 2,400# trailer fine on flat ground, and will even pull it up mild hills. I move it around with the PT all the time. Going downhill gets a mite squirrely, I admit. The PT just doesn't weigh enough.

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?? )

WAIT DON'T HIT THE IGNORE LIST!!!

Actually I've only replaced 2 floats in my lifetime (see my background as a mechanic, diesel and Wisconson/Robin engines). One was on another Merc 110 9.8hp, 1968, it was plastic and developed a pinhole, ran time at WOT. Could have fixed it with epoxy. The new design was the sealed foam type, the other was on a same era (because it came with the previous mentioned motor and 14' jon boat), was a Western Auto Generator. 1300w, 2hp Briggs, the brass float had a large hole from sitting for probably 30 years. Can't remember what the replacement float was on that one. But a new float, little cleaning, new air filter, and it did a little work during Ike recently! Probably a 40yo gasser.

Today CC offers the 5252 with a 25 hp air-cooled Kohler gas engine and the 5254 with a 25 hp liquid-cooled Kawasaki gas engine

cub cadet lawn mowers

These things have Cat 1 3pt hitch, rear and mid-ptos, hydrostatic drive and ROPS.

Are these CCs true SCUTS or glorified lawn and garden tractors? Your guess is a good as mine. My 21 hp (engine) Kubota B7510HST diesel has the same stuff and definitely is considered to be a SCUT.

Looks like a "glorified lawn and garden tractors" to me.
An expensive one at that.

Some folks think of tractors as having the same sized tires on all four corners and having up to three per corner!

They might remember what a carb was for but surely they ain't looking for one!

The ones you was talking about Moss are for chores!

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.

If you get your gas from a scrap yard, you deserve what is coming to you. Clean fuel is a common sense thing, clean cans are a bonus too. And perhaps changing the fuel filters too.

No where in his message did he imply that he was somehow using 'salvaged' gas.

yes.. clean fuel is common sense.

I've had more contaminated diesel than gas many times over.. from high volume bulk suppliers no less...

no one 'deserves' bad fuel.. but it does happen.

Come to think of it.. I've nver seen a gasolene algea...

But the gassers offer NO advantage whatsoever. Why bother. Rebuilds are no more complex on diesels, injector pumps get done by shops, so why bother with gassers.

And at the end of the day ...Value ..gas/diesel...I know what i can sell ..Diesels..?????????

 

[D7E]

Considering the higher compression ratio.. I would say that more skill is required to rebuild a diesel.

I can rebuild a carb on my desk.. I wouldn't feel comfortable doing an injector pump.

An injector pump and the injectors can require some specific test equipment not needed for the average gasser...

Why bother with a gasser.. remember.. Liquified petro engines are gassers.. and there are LOTS of applications for them where a diesel would not be appropriate.. like indoor warehouses.. So there at least one advantage that you dismissed out of hand..

We run cummins,ford,detroit,perkins,JD and cat motors from 50-600hp in tractors ,combines and trucks and dozers.Do all our own motors ,even rebuild trannies,Final drives...Not one guy on my yard will touch a gasser....Even the old "Bush men" will say ..."Too much trouble"...???????

 

[D7E]

Well my only remaining gasser is this fordson major and i'm at a loss with it...I ran it for 2 years on the log splitter on my firewood operation.
It tested good for oil presure and compression , Uses no oil,No rust and tyres are reasonable...?
I cannot make it run nice....Carb done..Plugs..wires..cap...Runs like a pig....? But very geniune tractor?..I bought a ford 7000 to replace it as my yard toy.
For sale ........$2450
Front end loader and bucket with it but some hoses missing?
I have diesel of same age .....$3000 with cab...Runs nice but motor worn...This will sell faster?
