Catzazz on hard level ground. I'd prolly start at small loads on hilly terrain and work up till you find its limits.
I do harvest some of the ramps,....I think I have nearly 10 acres fully covered with them. I should sell them to the local store as they are selling them for $17 per pound. I plan to work on the lower side of the hill, near my house this weekend to get a better feel for this trailer setup. It has surge brakes, but I do not want to bobsled the entire setup down a muddy hill as it has rained almost nonstop for 4-5 days. I will take a picture or five this weekend if I get it all loaded up.
What kind of engine and horsepower does that thing have? Looks like traction shouldn't be a problem. Yikes, grapevine in the background...
