Contemplating buying a weld on grapple from Green Manufacturing to weld on the top of my lighter duty material bucket. All I need it for is toting branches to the burn pile. I will have to overlay the top with a piece of heavy gage angle iron so it don't defrom the bucket, but that is it and I already have the hoses and my cab tractor has the 3rd function already plumbed in but I don't require a 3rd function valve. I just use the top set of remotes on the back of the tractor to actuate anything I put on the loader arms. No need for extra valving at all. I even set it up with disconnects between the loader frame and the tractor proper so I can remove the loader if necessary without disturbing anything.
I have 3 sets of remotes on each of my tractors and I rarely use all 3 sets except when running my new Kubota BV Sileage bailer.
All Pioneer fittings btw.
