I ran my riding mower over a previously unknown above-grade tree root, bent the blade on that side, and broke the spindle. It was $50 for a new spindle and another $15 for a replacement blade. I will have to do all the labor on the repair myself. But our local shop wanted about $100. That is a lot of wasted time and money.
I don't want to make that same mistake again. So, I looked around on YouTube to find some DIY solutions to grinding down tree roots that are sticking up above the ground.I found a number of people recommending the Harbor Freight Wood Carving Disc that sells for $16.99...
I put it on my wish list and then purchased it last week when I had a 30% off coupon. So, I actually paid $11.89 for the disc.
Yesterday, I took it out and tried it on my 20+ year old Ryobi 18v 4.5-inch angle grinder. It took me a few attempts to set it up correctly, mostly because I don't use my angle grinder very much. But after I had the guard set properly and got the hang of how to use the angle grinder with that carving wheel on it, I was able to chew through about 5 above-grade tree roots and 3 small stumps that I had around the property.For the small jobs I needed it for, it worked great. It had no problem carving down the tree roots to grade-level. The biggest stump I had was about 10 inches round, maybe an inch above grade. I was able to chew that down to about 1 inch below grade level in less than 10 minutes and then covered the stump with topsoil. That is all I needed to do.
If you have lots of big tree stumps, then rent a stump grinder for about $150 for a half day usage locally. For the tree roots and small tree stumps that I needed to knock down below grade level, that HF carving disc saved me a lot of money. Plus, I now have a tool accessory that I can use for lots of my typical root and small stump jobs in the yard. I don't know how long that carving disc will last, but it has already more than paid for itself.
 Here is a short YouTube video that I watched, cued to the review portion, of the HF carving disc...I wish I knew about these carving discs before I broke my mower, but maybe this info will help someone else before they break a spindle and/or bend a blade like I did.
