Combines M 3

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.

Also beyond what mo-farm said I totally agree but check the walker blocks and keep them snug. If it has a chopper make sure the edges don't get rounded as the straw will hang up in there and plug. 6-30 is pushing the machine on a sidehill in 180+ bu corn. Hydro, you might be able to run slow enough for 6-30 sidehill 180+, standard with the sidehill blower, still too much is going out the back. loved my late model M2(almost M3)

M2, M3 and l2, l3 machines are extremely hard to find because there are more buyers than sellers. If you find a good one, you had better buy it FAST. Good ones usually sell before they hit dealers lots. Tom in MN

There's an M3 w_2500 (approx) hrs 6-30 and 15' table on John Deere dealers lot in lebanon, IN. Roberts Farm Equipment Ph. 765-482-1711.

The M3_l3's were very good machines. look for the M3 with the large engine(145hp). I don't know what you plan to use it for but we ran one in the early 80's primarily in corn and beans. 630 corn head is a load in 180+ corn. Probably 3 mph maybe 3.5 if its dry. Will be stopped cold at 22% and up. We are in SW Il and corn yields run 130-160 with beans in the 45-55 range. We had a 15' platform, but wish we had 18' or maybe 20'. In 1984 or 1985 we had some corn in the 200+ range and had little problem at 18%.
