The operators manual I have from JD states:
Diesel 59hp PTO
Row crop diesel wide front approximately 6000#s dry shipping weightMost 3010s probably have been overhauled, so they can produce more HP, but depends upon whether the tractor has been set to match the new size pistons and sleeves. I believe the Nebraska tests stated fuel consumption to be something like 3.5 gph??? The one I have has the fuel injection pump turned down and is only putting out 52 pto hp. I figure it only burns as high as 2 gph maybe 2.5. The 3010 is rather light compared to its new version the 3020. A row crop diesel 3020 will weight something like 7500#s dry. Some will say you can pull 4 bottoms, but I've not really been able to pull 3-16s that well with mine (1 or 2nd gear). Red clay and plowing more than 6 inches gets tough. To get a good turn you want to plow around 5 mph... The 3010 hydraulic system is quite an improvement over the old two banger powr-trol system, but is rather weak compared to the 3020,4020s. 3010 has 3/8 inch hydraulic lines to the couplers vs. the 3020 with 1/2 inch hydraulic lines to the couplers. Only one transmission came with the row crop 3010s, and that was the syncro-range. It had 3 reverses and 8 forward speeds. The 20 series had only 2 reverses (although the third one is there if you want to cut away some metal). The 20 series also had the power shift option. These series of tractors 10 and 20s have been notorious for leaking through seals for the load control shaft. This shaft goes through the rear end case and manipulates the 3 point when under load. I had to replace these almost immediately after I got mine. It would leak 2 quarts of hydraulic fluid in 24 hours. Range of price is different from one part of the country to the other, and the options and condition make a big difference as well. Diesels run somewhere as low as around 4000USD to as high as 8000USD. Most 3010s that are in decent condition are in my own opinion worth around 5000-6000. Narrow front gassers are going to probably go the cheapest. If you can get one with a JD front end, you would be better off. I have a SpeedCo, and have to make my own parts or find something that matches, etc. I recommend only a light loader on this tractor...also pick a loader that is rear axle mount instead of mid-mount. Heard number of stories of having the bolts stripped out of the transmission housings when using the mid-mounts. It does have both 540 and 1000 rpm PTO, although, I can't think of anything that would run 1000 rpm that the 3010 could actually handle power-wise. An overhaul of my 3010 Diesel ran 3800USD just in parts. A new clutch was about 700USD. Fixing the transmission can run as high as 2000USD. If you go with power-shift 3020 that transmission can cost you about 6000USD to fix just in parts. Fuel injection pump rebuilds are around 1000USD. I got my injecters rebuilt for about 100USD. The rosamaster fuel injection pumps have a plastic disk that likes to break/wear out...about 25USD to fix. I like the break-away hydraulic couplers. Allows you to hook up implements without shutting off the tractor. It is a solid tractor and can be very reliable. The 24 volt system on the diesels can be a bit of a pain, but when working right is not that big a deal. If you don't like the 24 volt setup, there are conversion kits for as low as 400USD. The newer 3020s were 12 volt from factory starting in 1969 I think. Another item handy on the 20 series was the differential lock. That was available starting in 1966 I think. My 3010 diesel would be the last one to go if I had to give them up (have a '52 A and a '64 4020D as well).
