An Interesting idea, I Can Imagine Some Times It Would Be A Real Pain To Have, But It Would Be Nice Sometimes also.
I like electric better. With a cordless remote I can drag them in from 30 ft away. I guess I do have hydraulics on the stabilizers though.
I did not watch the whole video. I just skipped to him using. It is a really good idea. It looks like to me the linkage was bolted on. He should have used a pin so he could unhook it for it to stay down. Then with the removable linkage he could have made it so it locked up like TurboDiesel said.
Im willing to bet that my valve would kick off automatically when it would go to lift the load up to the wedge's height.
I might agree. My huskee valve kicks off really easy lately. (I put a valve on my neighbor's huskee a few years ago. It started kicking off more and more, then started getting sticky both ways. The detent balls wore out. )
