Gtread, would you mind telling me where you found those instructions or plans? Sounds like you might have gotten them from one of these LawnSite forums. I made a mistake when I bought my trailer several years ago, because I didn't get one with a ramp. Since I'm just a homeowner and I knew I would seldom be using it, I thought the tilt operation would be good enough for loading/unloading my ZTR. But it turns out to be pretty klutzy so I have been using a couple of 2x12 boards to drive the machine on and off. That works, but it's 's not too swift either, so I'd like to add a hinged ramp. I had looked for plans to do that, but never found any. If you have one, I'd like to see it or be told of a company that would sell me what I want.
