JT, are you referring to the RG50 by Rayco, and the 50TX by Vermeer? I have used the RG50 by Rayco... nice machine. I think the key with that machine would be the dozer blade. If you aren't concerned with the dozer blade... go with the 50TX. The 50TX is MUCH more manueverable, has lower ground pressure, and is more mobile. When I was using the RG50 I found that it didn't have the best traction. It works well, don't get me wrong... but I think that the tracks on the Vermeer would be better. However you have to factor in that the Rayco doesn't have tracks which can be taken off if you catch them on a stump or something while turning. I do believe also that the new Rayco's have not 50hp, but they now have 66 hp diesels.
