Welcome Texas papaw. What kind of trailer do you have? Is it like a single axle or is it like an old cotton trailer type? Will you be pulling in real muddy conditions or do you have hard paths? What type of feed will you be putting out and how much? One time we had what was called a trip hopper. It was made in Texas and had a 12v motor that would feed out a chute. It bridged bad with our mix so we went a different way but we had it on a little but tall trailer. I am sure the RTV would have pulled it and the 1500 lbs it held. You would need mud tires if your pastures get muddy though. Dry pastures shouldn't be a problem. I have pulled a single axle , treated floor ,12' trailer loaded with gas welder , acetylene bottles supplies and steel work surface with no problems with the RTV.I also pull skidded mineral troughs .I will say we put out so much feed we now must use a tractor.I also did a "no no" and made a wire spinner to fit in the receiver hitch so I can put out electric fence wire soo easy (Where the land is flat)!!!
