I have an older system, that I think was also called EZ-Hitch, which has a couple of spring-loaded pieces that swing over the bars to keep the attachment on. You have to swivel a pin in the back to keep the slider open to drop the attachment. The system has served me well, but after several years of spreading salted sand from my Herd spreader, the parts have become really rusted and a bear to move. Started surfing around to see if I could find replacements and came back to TBN (it's been a while), which is where I discovered the original system. So, after watching the videos on Jerome's site, I just ordered THIS EZ-Hitch set. Much simpler and more elegant design, if you can use such a word regarding tractors. Can't wait to get them and 'upgrade' my B7800. Thanks, folks, for the info!
