I had an M3 for several years and found it to be a very reliable machine. It's going to have a lOT more capacity than your K2. The M3 used the 301 engine but was available in 130 and 145 hp ratings. It uses a 40 in cyl and has 4 walkers that are 120 in long. The grain tank has 180 bu cap. As for what to check for in the way of repairs, be sure to look at the raddle chains,clean grain elevator,cyl bars,concave,and unloading auger as these were what wore out first on my machine. I would look for one with the 145 hp and hydrostat transmission. These combines are very easy to work on and most repairs can be made by anyone.
