Yep you can get quick hitches but it still requires you to drop the pto.It'll be fine for testing purposes, not for regular use.
I love doing dangerous and dodgy things to save a dollar, but I'd be hesitant to be anywhere near that, especially for the amount of bags you're going to be lifting. Maybe look at using two chain blocks at once so you have a bit of a failsafe.
Why don't you lift them up there with the loader and just chain them up to the box section? Provided you don't fall off the ladder, it's a far safer option, and you save a hundred bucks.
I'm surprised no one has made a quick release fert spreader with a similar release mechanism to a bale feeder.
Yeah I have been thinking of that. Lifting up with loader, then chaining up and over the box section so I don’t have to climb up anything
