Depending on how many acres you want to cover, most old single disk grain drills will work, 11 run is about 7 feet wide. An old steel wheel horse/tractor drill would hardly be an issue for your L3600.
Newer drills that are small pretty well died in the early 1980's. IH 510 semimount is 8 feet and uses lower links to lift for transport and turning, with rest of weight on tail wheel. Can still get parts @ CIH. MIght be usable on an L3600(?)
