I just joined the forum hoping that you guys/gals can help me out. I'm a hobbiest farmer mostly planting food plots for wildlife. I just bought what I believe to be a 3 bottom 4240 plow with a hydraulic lift. It hasn't been used in some time from what I was told. I'm starting to evaluate it and clean and grease it. The tires on it are automotive rejects that need to be replaced. the rims are 15&quot;. What size tires do I put on it? Are all three tires the same size? I've looked at the onine manuals and none lists a tire size.
I've never used a pull plow before, what do I need to know in setting the plow up correctly? 
I appreciate anny and all help.
Thanks,
Chris
