Bought a Rayco pull behind stumpgrinder in '95 and was immediatly impressed with its performance and veratility. Ground many stumps, some in difficult places and odd placements. Using a small walk behind Rayco in conjunction with the pull behind gave me as much ability, as the grinder market offered, so I went about my daily duties and learned as I went. I learned that grinding large stumps meant getting back in the truck to reposition the machine. Learned that moving grindings out from the wheels, to keep from pushing the pickup, (and tearing up lawn) was a pain. Learned that shoveling chips back into the hole was tough. Learned that moving grindings 'underfoot' was sometimes necessary to get off my knees or to keep from looking over the plexy glass guard. Learned that chasing roots takes way, way too long. Learned that my machines did not have the versatility as I had once imagined. They threw chips everywhere, on cars, houses, bushes, lawns, I mean really, Set up a 'guard' around 'the perimeter'? And all the stumps surrounded by vegetation, (Sorry Mrs Thomas , that Azaelia has to go with the stump, Ever had to say that?). And how many times I'ved been asked, "Can I put a tree back in the same place?" And the stumps on that slope at the Country Club, just behind their 'Signature Green'... If I could only reach those, I would get their treework for life. And the contractors who always dig their stumps instead of grinding , as this garentees complete removal (Ever ground a hole to set your grinder in so you can grind deep?). what about ROOTBALLS!, And UPROOTS! We have Numerous wind storms here in Tulsa, Ever see a mature Hackberry blown over? Ten or more feet of dirt pointing in the wrong direction is not an uncommon sight, nor a pleasant one . Stumps in flower beds, enough said. That stump just over that fence(Crap, hafto use the rinky dink machine), The one in that hole, or the one surrounded by that raised deck ? Also was wishing I could bid on Corps Of Engeneers job (137 trees/stumps along unmaintained Levees, many in the water, just out of reach), that required all stumps to be ground(even the ones in the water) as the roots will compromise levees. The list goes on and on. So I cut up my Rayco and built my own grinder thus solving all of the above. Machine grinds 6 feet deep, has a 14 foot swing, 17 foot reach, Ten foot tongue extention, and will grind 13 feet high. Chips pile neatly behind cutterhead, and boom can push chips back into hole or can push chips out for new plantings. And yes I got the Country Club Contract, and the Corps job Where I discovered that I could grind under water. w.k.b. tulsa

Thats cool!

This winter I'm planning on building one as an attachment for a mini excavator turned 90 degrees to the cab so it throws chips to the side, with its own 30-40 hp. powerpack. That way it attaches to a machine we already have, it fits through a 39" gate and grinds stumps that the big ones do.
 
We already have a grapple for our mini excavator( a CAT 301.8) its great for draging and chipping large piles of brush and also carrying and loading wood.

We also have an aluminum scaffold built for the side that goes up to 12', we can easily trim hedges up to 16' tall.
 
Hedges can be a real pain, I like your style. most customers dont understand the difficulty of making tall hedges look good . years ago step ladders and a 2x6 were the tools to use! Squirrly at best , Loaders rule.

I'll adapt one of these to your Excavator.

38HP 2 wheel choices, work is already done!

If you want to start building attachments for mini excavators, I can give you a few good ideas.

What kinda horsepower does it have(or GPM/PSI)?

If I had a mini, mini-ex, I'd mount the rake so the boom could do the work as the slew doesn't have much force.
