Been looking for a little bigger tractor to help out with my hay operation, I put up afew thousand small square bales a year and have done very well with my old Farmall M and Farmall H duo I've been running. Well times are changing and I have the chance to pick up afew more acres to bale each year so I'm looking at options for cheap power. I'm not going to run out and drop 30 grand on a "hobby farm" tractor so I've been keeping my eyes peeled for something alittle larger than my M with a diesel engine. I finally stumbled upon a Farmall 506 with new rubber on the back and very nice on the front, comes with a 5 way blade, 6' Bush hog, and a bale spear listed for $3500. What are some areas to look at when I go give it a spin this weekend? Are they decent machines over all? I'm looking into eventually buying a disc mower, will a 506 handle one? I mostly cut prairie hay with afew fields of broam and clover.
