Lot of crap been posted here to wade thru. I would stick to a wide front end tractor my self.
Many a old tractor form the 1960's and up in the 50 to 70 HP range sell for 5000 or less won't be beautiful nesserly but will run good..
I have a 1965 Ford 5000 gas And is a gas hog big time. and I am here to tell you it will blow snow over 70 feet with a 84" blower and it has LIVE PTO so if a big drift starts to bog you down you press the clutch a bit to stop tractor motion yet the blower will run and clear out. I would not worry about winter starting a diesel I would put a engine block heater in one of the soft plug holes. On my 5000 it warms the engine so warm it will melt snow off the hood. I also like the trac lock. Been stuck and hooked a chain on one wheel and locked the rear up and pulled it out. Parts are easy to find on the internet and at ford dealers. Caution should be used when you look at a SLECT O SHIFT trans ford. Commonly called selct o junk by many.
Here is one.

I also have a Allis D 17 a gas model and much easier than the Ford on fuel yet has close to the same power. Problem is the 3 point hitch with the early ones was a after market unit or a home made unit as Allis used what they called snap coupler system, not a bad set up but only used on Allis tractors so equipment can get pricy. Newer Allis D series can have a 3 point hitch but being newer and having that 3 point can be a bigger cost than 5000.
It does not have trac lock and I have been stuck in a little mud the 5000 Ford would power thru with the rear locked. It will also run the 84" snow blower very well. You use the power director to stop tractor motion and yet the blower will clear its self by keeping running.
Most D 17s will cost less than a Ford 5000.
Parts are easy to find on the net and at the Argo dealer.
Here is one with a front loader and home made 3 point hitch.

My brother has a 1959 Massey Ferguson 65 Diesel. It is a nice tractor Uses the clutch set up like the Ford for live power. he runs a Gorge White 7 foot snow blower with it and it does a very good job. Has mutla power which it roughly hi low range. Uses way less fuel than even my gas D 17,
starts easy on 30 below zero days but he does have it shedded in the winter and plugs in the block heater. Has plenty of power for about any farm chore Brother pulls a 4 bottom trailer plow in mixed clay dark loam soil. Of course it had the famous Ferguson 3 point hitch.

Neighbor has a IH 606 It came with what IH called a fast hitch so needed a aftermarket kit to give it 3 point. His is a gas model and seems to not be a gas hog. It has what is called a TA or Torque Amplifier that allows you to down shift to low range if the tractor starts lugging to keep the load moving. Parts are easy to get off the net and at Case IH dealers.
I could not find one for sale but this is a picture of one.
Case and David browns like 995s I don't know a lot about or know any one with one. I have heard they are easy on fuel and parts can be found off the net and at Case IH dealers.
I could not find any for sale either.
A picture of one.
There is also Moline's, Oliver's and White to consider parts can be found on the net and at Argo dealers same as Massey Ferguson, And Allis Chambers.
These are all American built tractors from the late 1950's to the early 1970's.
Many a farmer plowed and worked up hundreds of thousands of acres of crop land in Just 2 wheel drive. Many a lumber man skidded logs out of the woods with those tractors also. Just use your head and be care full.
A lumber yard near my Brother has 4, 1100 and 1135 MF tractors they still lumber with and even run their saw mill with one.
I collect Massey Harris tractors and Have from the little 11HP pony to the 71HP 555 diesel
