There are still plenty of 1010 and 2010s around running well, gas and diesel. Mine was manufactured late 1959. Not bad for a 60 year-old machine. 1010 and 2010s were fine for their time of development and had a lot of firsts for Deere. The wet-sleeves, rotary-distributor fuel-injection in the diesels, positive valve-stem seals. Power-shift hydraulic reverser in some of the crawlers.
The way I see it, many of the gripes about the diesels were due to owner and user ignorance. Especially what some people did to those poor things trying to start them cold.
