I wouldn't be with out my hyd grapple. I have the ROBO grapple made by circle 3 welding in Langford Kansas. I have the eight foot model. Its heavy but very well built. This guy has been building tree saws, tree shears and grapples for twenty years and has it figured out were the weak spots are and what needs protected. I have had this one ten years and its been used a lot and hard. Clearing pastures is hard on equipment. We buck all our wood using a grapple. We haven't buck wood on the ground since buying a grapple. Yes hooking the hoses up can be a pain. I have another set of ends with a piece of pipe and a cap on the end to catch the oil and I plug them into the grapple when I unhook it. When I am cleaning up the pasture I may switch between the grapple and tree saw a dozen times a day. With the grapple setting in the sun it builds a little pressure so I plug the dummy ends in the hoses. Tree saw motor doesn't build pressure so no need to plug the ends into it.

A stump bucket grapple should not be discounted by anyone with aux plumbing on a lighter duty tractor. Its smaller and therefore lighter while being made from heavy plate. 

I sketch and build and rebuild and anyalyze and resketch a continuaal development of attachments.. I actually thought i was gonna be an attachment manufacturer when i moved my equipment to TN and got it under one roof but the covid scene has changed the world. 

Anyways.. im telling you, i could not design a full width brush style of grapple capable of grabbing a log all the ways a stump bucket grapple can.  The only thing the stump bucket is not really good at is being a root rake.  But a root rake thumb is easy to make and put on your regular blade or bucket if you need that so badly.  

For anything logs that isnt dangling from a knuckle boom,  i will take a stump bucket hydraulic grapple and build it out custom for each persons use.

Had it been just for use on my tractor I would have gone with a hydraulic grapple of some kind. My tractor is already plumbed, but Lindy's little 30 horse would have had to have another valve added. Truth be told though, I may as well have gone with the hydraulic because she has never used the emechanical one on her tractor.

I see you have a 5410 on your signature line. No question I would go hydraulic with anything 50HP and up. 25-35hp compact tractors are a whole different class of machine.
