OhBoy, 2000s! Gotta throw my $.02 in here.
I agree with Junk. The gasser 2000s were economy tractors that came standard with transmission PTO. Live PTO was available, but I don't know if it was limited to the diesel version or came as an option for the gasser.
I sold my '69 2000 a few months ago and got over $4K for it. Of course, this was after putting new rims and tires on the back, rebuilding the carb, putting in a new battery, a new starter, and a few other minor things. It had around 2300 hours although the tach said only 1532 (I told the buyer, BTW). Hourmeter in tach did something funny while it sat in the barn for 8 years as I had checked the hours on it just before it went on extended vacation.
My Dad bought it used in '75 with 700 hours for around $3.5K as I recall. I'd say $3.3K is pretty good for a clean 2000, especially if those hours are correct.
They are a bit cold blooded but, before it developed carb problems, the 2000 would always start and, after a minute or so at idle, be ready to at least move out of the barn. Had to keep the manual choke partially on for about the first 4 or 5 minutes, however. I always thought of it as an easy starter.
My '69 had a single range 4-speed transmission. The tranny was about the only real gripe I had with that tractor. First gear was way too fast; something like 3mph at 1500RPM. It was faster in 1st at PTO RPM than my
L4300 is in 3rd gear at PTO RPM. Engine was very strong, but the thing always wanted to fly. I heard that in late '69 or '70 they started putting a single range 6 spd. transmission in the gasser 2000s. If your '72 has the 6 spd., I think you'll be much happier with it....unless the 2 extra gears were added on the wrong end!?
When I sold it, the tractor had a Zenith carb on it. The Zenith replaced a Holley that had a leaking float valve. The Holley's float valve seat isn't replaceable, so when that happened it was new carb. time. Unfortunately the new Zenith had a leaky float and the effect was the same....gas running out of the carb onto the floor and engine drowning in gas. At that point my poor old Dad threw up his hands and walked away from it. It was 8 years before I got a chance to work on it. After replacing the float, I still had to clean the Zenith out and put in a rebuild kit to get it running right.
Another minor gripe is that they didn't come standard with power steering and, by today's standards, needed it. There are power steering kits that can be added, however. Think they run about $500-$600.
It was always a good tractor on a 5' bush hog or a hay rake, and did a decent job with a 2x14 bottom plow as well. Even ran a small square baler fairly well except when the hay was very heavy...just couldn't go slow enough. It always pulled quite well with fluid in the rears. After the tire/rim change I had occasion to pull with no fluid. It didn't do well at all, just spun the tires. It was in the family for 33 years.
Think of a 3 cylinder gas 2000 as an 8N on steroids and you won't be far off.
FWIW
