The sg40 is a beast. Take care of it and it will take care of you. Grind on. Time to grind llc.

[@jacobmilne3034]

Get 2 pieces of plywood about 1sq meter each with a couple of hinges in between and set it down off the front corner of the grinder track on operating side. Will stop about 95% of chip/stones from hitting the operator and is hands free.

[@bloomstumpremoval]

The shield I use is my favorite tool. It provides something to lean on, helps with balance, protects from debris, and twice it's been used to keep people from walking into the spinning grinder.

[@stumpgrinders5084]

Just get a bigger machine with a window that blocks it or remote control.

[@daviddonahue1862]

Lots of grinding 😮

[@CatfishLove]

although the music is relaxing, I would have preferred to listen to the grinder. BIG STUMP!!

[@RiverValleyAcres]

How well will these machines handle slopes? I have a customer that prefers to grind the stumps rather than dig them out. Problem is the majority of the stumps are on a 3:1 slope. Thank you!

[@bloomstumpremoval]

Something with a wider track would be a better choice.

[@jacobl8877]

Not good on hills unless straight up or down I've rolled this unit before😮

[@jacobl8877]

For all our hillside work we use a 252 with a winch mounted on it

[@tonybabineau5642]

Hope you priced it good belts arent cheap

[@tomramey9]

Where did you get the blade for the back of the bandit? Mine did not come with it, and I don’t see it on Bandit’s website

[@bloomstumpremoval]

It was custom made by our mechanic.

[@CoryPeek1]

How much did yall charge for a stump like this? It's nice to see the SG40 is up to the task for big jobs.

[@bloomstumpremoval]

We usually base estimates on time. It's really difficult to estimate the big ones, so much can change after you start. If you can estimate time, then just plug in your per hour rate and you've got a quote. Rocks, bricks, concrete, obstacles - might cause adjustments.

[@stevenross1738]

Did y’all have a set price because of the size or price it by inch ? Curious of the price. Thanks. Just ordered SG-40 and ready to grind.

[@bloomstumpremoval]

We base our quotes on estimated time, obstacles, and ease of access. Pricing jobs is one of the most difficult things we do. When it comes to giant stumps, we find that whatever you charge - it won't be enough :)

@@bloomstumpremoval I have a giant stump I quoted a customer $2000 but it’s 16ft across and still has maybe 4 ft or a lil less above ground I was planing on cutting it as low as possible then going at it with my sg40 and my friends Vermeer with 50 hp diesel engine but the guy thought $2000 was too much this was a month ago the stump and the rest of the tree stil is there … did I over price … I’m starting out and yes pricing has been a challenge but so far this has been my only no answer which was probably a good thing lol ty for your time

[@247averagejoe]

What does grinding a stump of this size do to the teeth? Did y’all replace or sharpen afterwards?

[@bloomstumpremoval]

It had some embedded rocks, which destroyed teeth. Usually though, sharp teeth can last through a whole day of work. This was a half day.

[@edrose1175]

More $ in smaller job's let the competition take the big ones unless you get a bigger machine

[@mattwolf5707]

How long did that take you with that machine and what did you charge?

[@bloomstumpremoval]

It was over a year ago, I don't remember. It probably took around 4-5 hours. What would you charge?

[@toddscholze6168]

​@bloomstumpremoval I ground a hard maple last week that measured 72" at the cut! Had to grind 11 to 12 feet wide to get everything. Stuck up about 2 1/2 ft above the surrounding ground. I took it 10" below ground. I guesstimate 1 1/4 hrs and $425. At 25 minutes I was a little over half done. I hit 2 hard heads, a piece of steel, and a cement bock. In hindsight, I should've charged $100 more. There was a lot of solid stump to grind. Lol. Not many around can tackle something that big... and still do a good job! A run a rayco with 80 hp deutz diesel. 27" diameter cutting diameter, 32 teeth, 90" swing arc. Can go over 2 feet deep. When I grind, I use all my teeth. All the side ones. I take 4 to 5" cuts at a time. I swing back n fourth 70% fewer times then most grinders. If you take your averaged size stump, and if it's cut flush to the ground , I'll just drop in all the way to my belt guard (which is 10"deep) and just advance. No up n down movement. Just advance. Another example; 31" ash stump at the cut. Was cut flush. Had to grind 40 to 44" wide to get it. Swung left/ right 11 times, no up n down, and was done. 3 minutes flat. Took 4 to 5" per pass. I base my rate on time. I can grind really fast so I pass the savings on to the customers. On big jobs that have a lot of stumps, I've been as low as $1 an inch.

[@David-yy7lb]

A stump that size I would think it would take at least 25 years to rot out out naturally

[@williamcampbell8782]

How long did that "STUMP" take?

[@bloomstumpremoval]

About 4 hours. It would have been faster if it didn't have softball sized rocks embedded in the stump. We broke teeth and had to pry out the rocks.

[@rustysmith9621]

How long did that monster take to grind?

[@bloomstumpremoval]

About 4 hours. It would have been faster but a few brick sized stones were embedded in the stump. Took a while to remove them.

[@rustysmith9621]

@@bloomstumpremoval thanks I was wondering how to price that one. I have a big fresh oak like that to bid here soon. I'm new to the business. Out of Pa

[@bloomstumpremoval]

@@rustysmith9621 We've been using the Bandit ZT and SG for 5 years. We're much faster now than in our first couple years. If you are using a similar machine, make sure you have sharp teeth and change them if necessary during the job. A stump of that size might have taken us 10+ hours in the beginning.

[@wpog8453]

​@@bloomstumpremovalwhat changed things for you as far as efficiency over the years?

[@bloomstumpremoval]

@@wpog8453 Good question. 1. muscle memory with the controls 2. learning the approach, where to come in, which angles to hit 3. changing the environment to create a stable platform - pushing material or cutting channels to make things level 4. Using the machine to help with clean up - more machine, less human effort 5. Tools - sawzall, prybars, 3 lb hammer 6. equipment like barriers that are easy to set up... Even little things like chaining the machine to the trailer get quicker and more efficient with time.

[@Upliftyourbrothers]

Those are neat barriers? What are they called? Brand?

[@bloomstumpremoval]

Foards safety barricades.

[@OO-ne5yv]

How long did it take to grind that

[@bloomstumpremoval]

It was going fast, on track to finish under 4 hours. Then we ran into embedded stones... We probably put in about 5 hours, then came back for another hour later. It took about 6 hours but most stumps of that size are completed in 4. Our customer saw the issues and gave us a generous tip. Sometimes I think homeowners that hire stump grinders are the single nicest group on people on the planet.

Apparently you don’t run a sg40 with greenteeth.

How do you protect yourself from fliers? Chainsaw chaps?
