On craigslist. Different tiller but the same little rig. They turned the wheels out, we had ours turned in for tilling in the raspberries. I think dad bought it new in 68. This is even the exact model, might be the same tractor. 17 HP single cylinder, glow plug, and an unloader lever. You reached up under the hood right below the decal "r1500" and lifted the lever, she cranked over fast then you dumped it and "knuck-knuck-knuck" with a puff of smoke from all that extra fuel. https://seattle.craigslist.org/est/grd/d/renton-tractor/7396356958.html
You have all that property to take care of now, get the truck and trailer hooked up and get going.
That is a skinny little row tractor by design. I have so many fond memories but my experience tells me something wider is more suited to my terrain.
Did those have the 3 speed pto? They were great for running tillers.
I *think* I remember 2 It also had an integral mount tiller, it had 4 bolts around the PTO and then you hooked up the lift arms. The bolts would wiggle loose so there was a 3/4" box wrench on a wire, hanging from the fender handle. Easy to hook up, a PITA to have to tighten, and the center drive chain meant you had a good tilled edge up close on either side.
