I'm trying to identify this tractor, and if it is diesel or gas.

I did not find your typical serial number in the usual places. ( I thought this looked like an 841 / 118248) But now that I've zoomed in with a picture - I'm not sure) I did find what might be a serial number and model etched into the motor.

Any help with the model, diesel or gas. It did run for a bit when it was pulled out of the garage - now it will turn over and stall almost immediately.

Thank you in advance for your help.

Show me a good picture of the shifter and I will tell you if it is an X4X or not. The grill indicates that it is NOT an 801 series, but possibly an earlier 800. It has a carburetor, distributor and spark plugs, so it is obviously a gasser. Looks like someone used Ferguson green paint on it.

It has spark plugs and a coil.
Means it's a gasser.
The serial number looks like it is Hand Stamped in the usual place.
But it doesn't have the egg crate grill cover like an 841 would.
Either the tin has been changed or it underwent a transmission swap somewhere along the way.

Definitely a gasoline engine. It has a coil and distributor and I've never seen a diesel with those. :D

The picture of the stamped numbers looks like 641 and 118248 to me, which would make it a 1960 641.

If you zoom in on the first picture you can see that it's a 4 speed shifter.

You may be right. Looking at the model #
again that may be a 6 and not an 8.
Didn't the 8xx machines have a higher
hood height? Someone here could tell us
something about it by that.

I think you guys are right - it's a 641 with dual hydraulics.

This has been sitting in a garage for a bit.

Reverse on stick is up to the left, first to the right, I believe 2nd is down and 3rd to the bottom right.

I was able to get the blade in front to raise, and the bush hog behind was being stubborn - it eventually went up - almost as if the hydraulics had to be pumped up or something.

The choke didn't have a knob on it, but I since found where it was at.

At first run, in the drive way - I accidentally ran it out of gas.

It seemed to be starving for gas and had a clear fuel filter that I replaced.
I removed the screw from the bottom of the carburetor and some crap came out of that.

When I ran it out of gas - it sounded great. Do you guys think I pulled crap into the carb?

Had trouble getting it started again - charging the battery overnight.

Some kind of guide on this thing would be great.

Maybe the fuel problem is with the shutoff valve.

How should I use that shutoff valve, turn up down, or turn several times...

Enclosed picture of the fuel shutoff on this.

Is this a ball valve type of setup, or should I turn it clockwise for on and counterclockwise for off?

This could be the fuel problem....

The pic doesn't show it very well but it looks to me like a 1/4 turn brass valve. To check fuel delivery, shut it off, remove the drain plug from the bottom of the carb, put a one quart glass jar under it, turn the shut-off back on and watch the flow. It should run a pint in a minute or less. If it slows to a trickle, there is your problem. The gas in the jar should be clear. if cloudy you have water. If it is slow try it before that filter. If it is slow before the filter it is probably the screen in the tank. Tanks on 50 year old tractors often contain a lot of crud. I have had great success cleaning tanks out with a siphon.

It looks like a common quarter turn brass valve. Any time the handle is in line with the fuel line, up or down, fuel should be on. To turn off, turn the handle either direction so that it is 90 degrees to the fuel line .

Does anyone feel that this is a huge loop to get from the gas tank to the carburetor. I haven't found a picture of how an original one is mounted. Maybe all that tubing is starving the carburetor.

The extra length in itself will not impede flow. you could replace the whole tractor but why not do some standard testing?
