Stump Grinder Advice

It all goes back to efficiency again. When we bought our grinder it wasn't because we were over paying a sub too much money for so many stumps. 9 of 10'times for us we are at least cleaning up the stump chips if not installing loam when grinding as well. We were being forced to return to jobs to clean up after our stump guy had gone there. Not efficient! We bought an rg50 and have had pretty good luck with it. We rarely grind stumps that are from trees we have not removed, and the grinder probably goes out 3 days a week on average. Well worth having if you ask me.

That's what we have. I would highly reccomend spending the extra money for a greenwheel, it makes a great difference.

What is the limit that a grinder like that will do? Efficiently? This makes sense for us because the dingo is on almost every job.
 
I have, unfortunately, ground a lot of stumps. The last couple of pictures are more like the grinders I would buy; they need to fi5 into back yards, you need to be able to build impromptu ramps/decks to get past ponds, retaining walls and other obstructions, etc. Can't speak much to brand reliability but don't buy a monster in my opinion; i already had to hoist smaller grinders over fences with a hiab crane all the time.

I'd say anything under 30 inches that isn't sugar maple, is decently efficient. The biggest downfall is that the weight isn't put over the grinder wheel, like the 38 special, so it would jump alot. The greenwheel that we've been running for the last two years has helped alot with that.

We've done some huge stumps with it. It won't win any races but it is cool to be able to unhook the grinder and grab the bucket for cleanup.
 
Same issue, few pages later. Fly to Georgia, load the Rayco on the bed of that Sterling Truck crane, drive 'em both home! Or if you're tied up, maybe hire @oldoakman to drive 'em up for you.

I'll be selling my rayco rg 90 with 1500 hours soon..
Its a back up... gonna get another rg 100 so won't be needing it... 1500 hours.. all new hoses through the boom. newer bearings on the cutter wheel... 24,000... can have the trailer for an extra 1,000
 
I bought one used carlton i think it was a 7015 blew the motor three weeks after i bought it. i will never ever buy another used freaking stumper. i looked at tons of them, demoed them.. and frankly they were all pieces of shit. i ended up buying a brand new vermeer 362 in January after demoing several new machines. My dealer here is fantastic and johnny on the spot with service. big machines equal big maintenance. when that kolor goes out in a year or so it will cost me three grand to go through the machine and put all new bushings, bearings, belt, pulleys, and a new motor. the up front investment was $22.5k my payment is $412 a month. That machines makes money hand over foot. It goes out with the production crew and as stated before as soon as the trunk hits the ground the grinding starts if possible.
 
I would never buy a grinder with less than 90 horse power.... but that's just what makes sense for me.... as with all things in tree work there are just too many variables to say this is right and that is wrong..
 
.....just was reading this thread. Didn't realize so many people hate dealing with stumps. Honestly, after talking to people about working with them as a sub, I'm thinking of making a plan to get a grinder. something along the lines of a rayco super jr, something that will cruise thru most stumps. no ones asking me for much pruning, and no one owns a grinder.

A sub that climbs and does your stumps? Come ooooonnn, that sounds like a good combo. No?

That's exactly what I do climb and do stumps.
 
Best secret in grinding is the Toro stx38. I have a 65hp tow behind but the small machine does most of the grinding and while other work is being done any groundie that just started that day can safely knock out stumps (we've done em 10' wide) while you and others are doing more...well...treemanly stuff. It zigs when others can't and zags when others only hoped they could and it is a sure winner in a straight up drag race with any machine for ground speed, fits on the trailer with your mini.

I have had mine since they gave me the proto to demo then bought a new one, maybe 2 years ago? Never been in the shop for anything, seems bulletproof. Also when you have a giant to do like the 11 foot wide one last week where I could get the tow behind (with remote) to it, it helps by going around and taking out all the stick peninsula like buttress..es. Makes the stump much easier to do with the big machine after a little prep. 100 hp for a stump grinder? Seems way over kill and probably a killer to the wallet when $ could be spent more wisely elsewhere.
