new owner looking for help/knowledge

i recently aquired a 1950 allis chalmers b, and since i know absolutely nothing about tractors i would like some guidence. i would like to know if it has a 3pt hitch, or what to look for so i can get a brush hog and maybe something to push snow. it has a pto, but no hydraulic lines. it has a single plow with a disc that is lowered by a hand lever tilt and depth levers. i know this is a lot to ask for but it would be greatly apprieciated. thank you to anyone willing to help.

New here with a B also.  This is what the factory Hydraulic looks like.  Has a pump on left rear of PTO- (first picture)

Second picture shows after market hydraulic pump added to run off fan belt.  PTO is after market.  Have seen them (3pt hitch) selling from @380$ - to 600$.  Pump almost looks like a power steering assembly.

Most likely your PTO is the smaller (1-1/8") size and won't work with PTO driven implements unless you get an adapter. These tractors really aren't ideal for brushhogging compared to newer tractors with better hydraulic setups. PTO/hydro pump stops when the clutch is in.

We built a heavy duty 3 pt for ours, with a large cylinder like the one pictured above and the tractors high pressure pump the lift capacity is more than you could use without breaking stuff. I can post pictures if you wanted.

Bee's first picture shows lift arms for a Snap Couple set up which very few B's had. Many people have added 3pt to their B's with the original hydraulic pump as the power source. Most have found the front of the tractor to be light and need weight to pick up a bush hog mower but adding weight up front makes this possible.
 The hand lift and plow might be as valuable to a collector as the 3pt would be to you. Take a picture of the back, right side of the PTO and post it here or email to me and I will post it. Then we can see what you have and what you will need to change. Charlie email is 1954w45@gmail.com

It looks like you would need the hydraulic pump. If your tractor has the cam for it, it would be a simple bolt on change. 

What about the possibility of his tractor being an earlier B than what he is told? Were the pumps not standard equipment on later models?

acep, If you do wind up using a bush hog on this tractor, don't get one over 4' wide and be sure to get an overriding clutch to go on the PTO shaft. Tractors without live PTO can be pushed into a rock wall or a tree by the inertia of the bush hog even after you push the clutch. The overriding clutch helps prevent that. Bob@allisdowneast

thanks guys, i have to be honest i kinda expected to be pushed aside because of my lack experience. but u guys have been very helpfull. yes it has a round plate on the right side of the pto. and the serial # reads B31918 or like it says right above it, tractor no

jacob thanks and yes you are right the casting number on the block is AM2916-11

There are 2 that will serve you well.  A parts manual will have a diagramof every part on the tractor.  Very handy.  The second is a factory service manual.  There is also an I&T brand manual, and we sell a lot of them, but by far, I prefer the Factory service manual.  It will provide complete tear-down and rebuild, plus all torque specs etc.

Yes.  If you can find originals, they are very expensive (usually).  They are reproductions of exactly what the mechanic would have had if you went to an AC dealer.
