$2k for a 450, jump on it unless the u/c is shot. gas engines are fine, much nicer in the winter if you need to push some snow.

If you dont get it, shoot me the contact info/location :)

There's no real noticeable difference in power. The 450 180 c.i. gas engine has the same power-output as the 202 diesel. I've had both, and we sold many of both-ways. Even with lugging down and pushing dirt - i.e. when torque is relied on, I've never noticed much differnce - at least not with the first 450 engines. Later 450s got bigger diesels - but the first diesels are same 3.8" bore as the gas engines - with the gas engines having slighlty shorter stroke. Only good thing about the gas versions is they start a lot easier in cold weather - if well maintained. But, when pushing dirt - they will often use twice the fuel as the diesel. And, most likely you're going to be using highway-taxed gasoline - whereas, a diesel, using half the fuel, can be using lower-cost heating-oil/farm fuel instead. So, it's a toss-up. Gas engine is somewhat cheaper and easier to work on - and can be easier to start if well maintained - but the diesel last longer, is worth more, and uses half the fuel when being worked hard. I've got a gas-engine 350 at my cabin in the Adirondack mountains. It has the exact same engine as the first-model 450 - except minus one cylinder and no balancing shafts. Nice thing about it is - I have no electricity there for a block-heater - and I can always get it started regardless of weather.

From 1964-1970 they made a 450 gas, 4 cylinder 180, 57HP. After owning many gas a diesel equipment, I personally would go with a diesel on a dozer. If you are just going to use it around the farm, gas would be fine.

Putting in a new ring-gear on the flywheel is not too big a deal. Do it yourself with 8 hours work and $150 in part. Pay a dealer though, and it can cost you $600 or more. You didn't mention if this is a loader or a dozer - and if a dozer - inside blade or outside blade? You'd better run the machine before buying, get it good and hot - and see if the trans slips - and - if the engine has any oil-pressure at idle-speed.

A loader or outside-blade 450 for $2000 may not be cheap in the long-run. Depends much on the undercarriage and HL-R trans. Those transmissions are getting so expensive to fix, that I've seen several 450s get scrapped and parted out lately - since they were too expensive to repair.

You could pay $2000 for the crawler, and if the trans starts to slip - it could cost you another $3000 - $4000 to fix - in some cases, more.

450s for sale in the $2000 price range are not rare - if they need undercarriage or trans. work.
Theres a 450 loader for sale, right now - near me. ROPS,Good undercarriage, rear ripper, but the motor needs work (diesel). $2500 Last month I looked at a 450B dozer with 6-way blade, 1/2 worn undercarriage and the trans. slipped when hot. It sold for $1800 and the buyer is parting it out. Figured it would of cost as least $6000 to fix it otherwise. I was a Deere mechanic most of my life - and they made some good machines. But . . . a 450 can be 40 years old and uses a LOT of proprietary parts that only come from Deere. I would not own one - unless I got it dirt cheap. A 350 or a 1010 yes (I've got several). My neighbor just bought a 350 diesel with inside, mechanical 6-way blade, no reverser(clutch driven), winch, and ROPS. Pretty bad undercarriage but it runs great. He paid $3000 for it. For an older machine for occasional use, you're better off (in my opinion) with a crawler that uses more generic parts - like an old Allis HD5. Most built with truck parts, has a Detroit Diesel engine, and they usually sell cheap.

A diesel has more torque, I would not say a gas is under powered. The gas is probably less expensive and easier to mantain if you do not have a lot of experiance with diesels. The price seems pretty good, i dont know much about the ring gear. If you just want something to mess around with, have at it!
