I have had a couple of Johnny Bucket SR units -- one on my 322 that I bought direct from Johnny Products (in fact it was the first one they did for the open frame tractors and was SN 1001...so it had a slightly larger bucket than the later units that were made to comply with shipping constraints.) The other was one I bought locally at a very good price and put on a 318. Here are some pictures of these set-ups:
These buckets are very handy for moving materials around your property and even for light scraping (I never had the toothed attachment bar, but did do some light shaving with it on some pathways -- results seen here. All the wood chips were also moved and places with the JBSR, as was a lot of tilled up soil...
You can't lift material up into a trailer or truck bed...so the Buford bucket is a bit closer to being able to do that. I did not want to load material, and because of the many sloped areas of my property I did not want the safety/tipping issues of a high lift when my wife was using it.
The beauty of these small buckets is that you can take them off and put them on with little hassle, and they store in a small space. Real FEL attachments do neither of these desirable things -- but they do lift loads of greater weight to full loading heights. And true FELs cost at least twice what the JBSR costs.
