Grind stumps or dig out????

Looked at a job today. Owner wants to clean up all the downed trees, remove stumps and bushhogg the property nice and clean. Wants it done before Christmas.

My question is about removing the stumps. The owner asked about digging the stumps out. I counted 13 stumps of various sizes. There are 2x tht are least 48" across at the base. No room on the road to bring in a large excavator or would it be cost effective. I would think cuting the stumps to ground level, then grinding would be the best option.
Starting 2morrow I have a Bobcat 334 on a 7day rent for another job. Would the 334 be able to dig around these stumps, so we can cut them into manageable pieces???

Few pics. Ill try to get better pics 2morrow. I ran out of daylight

Small stumps could be "popped out" with a bobcat, a 4' stump isn't gonna be fun, if you cut it low it will kill a chain, stump grinding might take a while unless you have a big stump grinder, and you will leave a mound that the feller might complain about. If you have access to some big equiptment you might do the whole job in a couple of hours, if you can get a 5 hour minimum plus hauling the equiptment it would be a profitable day.

Cutting stumps is terrible absolutely kills chains. You can do anything, it more about how long will it take.thats a decent sized mini and should handle most of them. What does he want to do with the property after? If its just going to be a clean field, I would call in a stump grinding guy and see what it would be to sub it all to him, then you can decide if renting one and doing it yourself is cost effective.

Depends on the stump grinder and also what type tree. I have cleaned upo after many tree services making a yard of grass out of what was a yard of trees and learned quick the limitations of a stump grinder. Most grinders will not take the time too grind the tap root and the feeder roots. Even if the stumps are ground I find I always end up digging all the stuff up they leave behind and I never have stumps ground now unless it is in an inaccesible area or too near utilities too dig it up.

This is what I specialize in, unfortunately, because of the prevalence of oak wilt here. A lot stumps we deal with are 4'+.

If you dig those big ones out, you are going to have a lot more to haul off/dispose of but you are set up for that with the dump trailer and skid. The 334 will dig those stumps but they will be heavy if they are not rotten and even then, they may hold onto a lot of dirt that you can't get off.
If you have the time and ability to easily haul that stuff off, digging would save you the cost of a stump grinder and the time dig versus set up a grinder or hire one out, will probably be about the same. You will have a little more time filling in the holes but you can do that when you are picking up debris.

If you wanted to grind and didn't need to get them too far below grade, then you won't have so many chips to deal with but if you are going to mow, it will smooth that area out. Your climate will help decompose chips quickly anyway.
Unless you have extra fill or material to push into the holes, you know you will have some depressions after you uproot and depending on the land use, it may affect someone. Stump grinding will leave a depression over time but it won't be near as bad as if you pulled a stump out and didn't backfill and compact.

I'm sure you already know this but for other guys who don't cut stumps often; as long as you clean around the base of the stump, you can cut with a chainsaw all day with minimal sharpening. A lot of guys that run into problems cutting stumps don't take the time to get the dirt/debris away from the base of the stump and end up dulling their chain or pulling in dirt/rock etc.

Good luck!

Spoke with the property owner again. He wants the stumps dug out and he will have fill delivered for us to spread.

I counted 19 stumps today of various sizes. Around 2-3loads of tree debris to be removed and wants it bushhogged.

I'm still looking for the closest place to dispose of the debris. I've got the Bobcat 335 excavator until Wed of next week.

How would y'all price the stump removal?

More pics.

I think you will make some money there. Nothing ever goes as smooth as we plan.. at least almost never but with the extra time you have the excavator, you can play with the stumps if a few are tough. If that 335 is running good, it should make short work of a lot of those stumps.
Let us know how it turns out. Were you able to find a dump site close by?

I found a dump site about 5miles away.
, they charge $100 to dump my 23yd dump trailer. Ill be able to knock over about 7-9 stumps with my Skidsteer. Make a few cuts arounds the roots and push it over.

Most of the oak tree wood will go to my brothers house for us to split and dry for next year.

I'm loving working with this Bobcat 335. Great machine.

$100 to dump 5 miles away is a great deal especially with the amount you can get into that trailer. I generally have to haul about 15-25 miles or more one way. It's illegal here to haul off to burn though a lot of contractors do that. If we can't grind or mulch on-site, we have to find someone who will use the wood/stumps for recycling.
I can work in the mini ex all day and if you can get one with a thumb, you can really load that trailer neatly to take carry more.

That oak stump is going to be a big girl when It comes out of the ground. Im not so sure a mini is going to cut it. I know you have to use what you have, but lets be realistic spending 2 hours killing a machine over a 10,000lbs stump may be a little much.
hopefully they are more rotten then they look. Atleast oak trees only have roots down about 3' and spread out along the ground.
If you do manage to get it out do take a picture of it on the trailer!

Just for reference, I have about 2000 hrs of seat time in a 5 ton john Deere. (50d).y machine has just over 3k hrs

She is a short stick with a hydraulic thumb.

I have dug out many stumps that are in the way of foundations. Did a 4 foot oak stump, took 3 hrs to dig out and loading the trailer....and it was all I could fit into my 7x 16 bri-mar trailer

Don't under estimate stumps , those pine stumps will be a bugger

Well we got the job start Monday. I'm going to bushhog the place first. Pile up the loose debris(may push some of it into the bigger stump holes) and then start on the stumps.

Guess I need to service my chainsaws this weekend too.

Great Christmas present.
