The 276 is close to the 2420 but even closer to the 2310, though it does weigh more.( Based on 276 year, my powershift is on the floor, 2420 is on steering column.) I have a 2310 and the repair manuel for the 276. There are a few differences, but the engine, transmission, and final drive are the same. Tire sizes identical, and sheet metal parts appear the same. One interesting difference is the 276 has a water pump and thermostat, where the 2310 only has a water pump. This comes to mind from the thread about adding a thermostat. Other major differences pto speeds and throttle direction. Also 2310 has no ROPs though I think the 276 would fit based on the diagrams in the repair manuel. 276 has hydraulic filter 2310 has none. 276 has draft control or option, 2310 does not. IMHO the 276 is a better buy if condition is the same. One other plus parts are available as the 276 was imported new.
