stump grinder question

[miko0618]

Does anyone run a smaller grinder? Something like a Toro sgr 13? I need to grind stumps. I have been subbing them out with no profit. What I don't want to do is buy a bigger one at a cheap price because it'll constantly break down. Sooo... I was thinking of getting a smaller one and making money with it. I currently have about $2000 in stumps waiting to be ground. I've rented the type like I mentioned but the cutters were so shot it just smoked the wood. With good cutters and prepping the area properly, would one of those be ok for a few months?

Just rent a bigger one for a few hundo more and get jiggy wit it. yes the little grinder will grind but how fast do you want to make your 2k? How big are your stumps? How many?

 

[miko0618]

Average would be 24" across close to the ground. There is none to rent.

It took me 45 mins to grind a not so big red maple stump with that 13 hp thing maybe 5 mins with a 40+ hp grinder 24" stump don't know how much other work you have but I'd just sub it out I Def would not attempt it.. and that's just one. Find a guy for 10 bucks an hour and give him a week to finish them all

Can you get a big enough grinder for $5k? Used obviously.

I've used those small rental grinders more times than I want to remember on stumps that we couldn't get our bigger machine into (small gates, in planter boxes, in hedges etc). A couple of things to think about, if you are only grinding just below the surface ie they're putting in grass afterwards isn't as hard as having to go deep 10". A bigger heavier machine will allow you to get deeper faster and the guards don't get in the way. Second, you're not grinding diameter, you're grinding volume of stump and a lot of the volume of the stump is on the backside, where you are now cutting across the grain, rather than with it. A heavier machine will help you power through that. At times, the backside of the stump feels like you are using a sander.

I've never measured it, but I would estimate that even the smallest self propelled grinder eg Vermeer 252 is going to be about 5 times faster.

It depends on whether you have other work to do instead of grinding your $2000 worth of stumps. If that's all you have, then go for it. If you have other work that would be more profitable, then find another solution.

Subbing them out with no profit is bad. Doing them yourself with no profit is worse. Selling my 25hp self propelled grinder was the best decision I ever made. Grinding stumps pays about the kind of money you get for mowing lawns or flipping burgers unless you've got a big machine.

I found a place to rent a big one. I could pay a guy to grind for weeks at a time and do well. I just dont want to invest in a machine that wont do the job or breaks down.

Milo, go back and read your original post and think about the advice you would give yourself. Substitute chainsaw for grinder.

"I'm thinking of buying buying a new ms170 instead of a used ms460."

You've been in this business long enough to know the misery of trying to do the job with undersized equipment. If you're going to get into stump grinding, then do it right.

A decent used grinder is going to be in the $6-8,000.00 range. You'll recoup 25-30% of your investment the first week. And yes, you'll have another piece of equipment that will require maintenance and repairs.

Of course, you'll also find yourself working an extra 10-15 hours a week doing the work your sub is doing now. Look at your market. If you think you can sell enough stumps to keep a decent machine going going enough to justify hiring another hand to run it, that's great. If not, just keep subbing them out and tack on a little extra for yourself.

Machines break down. Nature of the biz.

Just a slight derail, can you imagine the cost to repair when one of the sensors in the self driving Google car breaks down?

Lol can you still get a DWI in one of those??

Matters what seat you're in I guess. You can get a dui for just sitting in the driver's seat drunk.

Here you gotta have the keys in the ignition also, showing an intent to drive

That's why I recommend the Vermeer sg252ch, the cup holder option is worth every penny...

About 0.000021 of a seconds worth?

A 12hp is part of my business.
It does stumps my bigger machine can't get to.
It only makes sense to use, if the stumps are max 20" and depth needs to be 5". Close to impossible to use on slopes.
Speed wise it's not that far from a 27hp if you keep razor sharp teeth. Spending time and money on keeping them sharp is the key on small units.
Big stumps are a pain on these, sometimes impossible to do a proper job.

When getting into stump grinding you suddenly find yourself buying lots of tools and spare parts and you just spend many evenings in the garage doing maintenance, again and again and again...
