Man vs Stump / Chainsaw sharpening / Is this normal?

I took down a small tree (10 ft? pine?) growing under a maple tree. Because I'm impractical and like a challenge, I decided to remove the stump by hand. For this exercise a chainsaw counts as a hand tool.

One of the techniques I used to make the project possible was to make vertical cuts into the stump and to pound a steel wedge into the new gap. I think I got exactly one cut before it would cut no more, just producing smoke. Was I cutting through particularly hard wood? Seems like I spent more time sharpening the chain than cutting. Anyway, off to sharpen the chain so its ready next time I need it.

Oh, I did get the remainder of the stump out. Tomorrow I'll fill in the hole.

Needs more chain oil.

1. My guess is that vertical cuts mean that the remaining stumps pushing in on both sides of the blade, due to the fiber structure of the trunk.

2. How did you get rid of the trunk?

Pine shouldn’t be especially hard.

How sharp was the chain to start? Correctly tensioned?

A tank of bar oil should last roughly as long as a tank of fuel.

You didn’t hit dirt, did you?

Yeah, either dirt or you may have not been able to go any deeper, which means you end up with burnished wood that gives off smoke.

pine is also very sappy wood that can gum up stuff quickly

This with the compression of the stump and dirt were probably the cause.

A dull or damaged chain will also smoke quite a bit because the wood just gets rubbed and not cut. “Someone” allowed a neighbor to borrow ours and it came back damaged. I did use it yesterday on a few pine cuts and it was miserable. Threw a new chain on today and it was like buttah, sap didn’t slow it down.

I’ve removed small stumps with a shovel and pick-axe. It works, you just need to keep at it and keep moving around. The easiest one I did was bigger. I put a pile of sticks and branches on top and got them lit. The fire never got too big but the stump burned nice and level to the ground in about a day. No fill in required.

Nothing here is matching what I was experiencing. I'm trying to figure out how a tree with needles could have such hard wood. Its possible that my sharpening technique isn't very good...but I'm also under the impression that sharpening the chain isn't that hard and can be done rather quickly. This is my second chain, I assume the first chain just needs sharpening but I did have the experience of going from 'this doesn't cut' to 'omg this is easy'.

Is it really possible to damage a chain? I mean, I guess so but it would take something really stupid. Just sharpen it.

It has plenty of bar oil. There wasn't any pinching as I cut.

I did hit dirt at the very end, but the chain was already dull by that point. And it was extremely helpful for removing the stump.

I sharpened the chain last night but its going to be a little while before I have something to cut. I guess I could find a small pine branch to cut just to verify.

Cutting into stumps is very hard on chains, you can hit small pockets of dirt many times.

It takes lots and lots practice sharpening a chain with a plain round chainsaw file. I've been using a guide and file for about 30 years and have gotten pretty good at it. They tell me something like what's linked below makes it even easier, you have to make sure you get the right size.

“ I'm also under the impression that sharpening the chain isn't that hard and can be done rather quickly “

My experience is that it takes much practice to be good at it freehand. A good sharpening jig makes it much easier.
