This site was taken down by a hacker in 2018 and I haven’t had a chance to get it back up yet… There’s a blog post that contains a bit of the former information on building your own over at http://www.slowhandfarm.com/2019/02/19/farm-hand-carts/. I still have one of the fully adjustable carts available for sale. Let me know over there if you’re interested – $770 bare frame and wheels.
You might also be able to find some of the old info on one of the internet’s archiving machines that shows websites in their old forms – shoot for early 2018.
The rest of what you see here is WordPress template stuff I’m not even going to bother editing (it’s taken me a year just to get this little bit up). I do hope to get everything back up and running soon (like maybe by 2021?)
