I have a chance to go look at a farmall 300 with fast hitch that comes with mounted planters cultivators and middle busters for sale. It seems like a pretty good deal and I have been looking for this set up for a little while. I have never been around this type of equipment since it is rare in this area so this may seem like a stupid question to some but is this equipment interchangeable with my 400? My tractor also has a fast hitch if that makes a difference. Just to clarify, this equipment is mounted in front of the operator not behind. Where can I find a good place to do some research on these before I go look? Thanks who all helps.
