Super M pricing and questions

(Please forgive any incorrect terms, I'm an old farm boy needing an acreage tractor.)

Specifics:
Super M serial SM F-49219 J
- narrow front (quite wobbly w/ lots of steering wheel play)
- live hydraulics (factory)
- aftermarket power steering (belt drive, L side)
- 3 point hitch(light weight)
- drawbar mounted on rear axle
- 12 volt conversion, new battery
- no lights
- crappy loader w/ blade, no bucket
- small seep in radiator - no water/antifreeze in engine oil
- no engine oil leaks, no blue smoke, starts good
- might be missing, hard to tell
- new rear tires, good front tires
- sheet metal dented and dinged
- clutch, brakes and all gears work

Main uses: snow removal, light dirt work, sickle bar mower.

Questions:
Is it worth $1500? They were asking $2100 to start with. Not going to use that loader, think I have another to put on it.

How hard is it to fix the front wheel wobble?

Can the power steering leak be fixed or are parts impossible to come by? Its not a hose leak.

What can you use the 3 point for? It was so flimsy looking and the pin holes were quite small.

What does a 3 way valve assembly cost roughly? Wanting to have up and down pressure for loader, bucket and possibly the 3 point or other attachment.

Anything else I should have checked?

Thanks!

Thanks for all the help folks. Drove it the 35 miles home today. It ran pretty hot (200-240 degrees) but never boiled over. Up hills it sounded like a 2 cyl JD but never had to shift out of 5th.

At a fast idle it wasn't missing so hoping its a timing/wiring/carb issue. After an oil change and tune-up she should be much better (fingers crossed). Then on to the wheel wobble, the power steering may not be leaking as much as I originally thought.

Steering wobble - If the cause is worn pivot shaft bushings, $50 in parts and few hours time to R/R the front end will cure it. However if the problem's worn gears in the steering pot, parts (new worm and gear) will run several hundred $.

PS leak - You didn't mention whether it's got Charlynn or Behlen steering. If Charlynn check is the hose manifold block at the steering motor. Often this works loose and leaks LOTS of oil. Tightening the two cap screws holding the manifold block in place, and maybe replacing the two O-rings underneath will fix it. However if the motor is leaking internally the only fix is to replace it ($300 - $400).

Incidentally if the PS is Charlynn check the spline coupling at the front (output) end of the PS motor for radial play. If any is evident it will contribute to steering wobble. Figure $80 for a new coupling.

Regarding the price, if the tractor indeed has new rear tires, these alone are easily worth $600+ as rusty suggests. And if the engine miss is simple (fouled plug, loose wire, etc) the fix is easy and cheap. So $1,500 for that Super M as is may be close to a fair price.
