Even though the yard is a muddy mess (and will be for a couple more months), I could not wait any longer and had to try out a PTO powered implement. So I got out the used stump grinder I got and hooked it up. I had just cut down an 18" ash a few weeks ago so I tried it out on that. Within 10 seconds, I confirmed I wanted to reverse the blade to throw the debris away from me. So I switched the fittings and reversed the blade. Much better just like everyone says. It took about 25 minutes to grind down a stump that was about 3" above ground to about 10" below ground. The teeth are extremely dull and it created sawdust more than chips. But that may be because I am not using the correct angle. When cutting down the large roots, large chips did fly. My stump grinder is an older version without replaceable teeth.

Some people have mentioned how long it takes and how much the tractor shakes but my experience was pleasantly otherwise.

The front and back wheels left ruts where it was sitting but the lawn is so mushy that you can make ruts with your feet by pushing against the grass. Definitely not the tractor's fault. Ran the tractor with just single tires.

Even with the grinder reversed, a little gets thrown towards the tractor. This happens especially when you start hitting the clay. Fortunately, I was prepared and was wearing my safety glasses and my chain saw hard hat with the metal mesh visor. I am sure it looked pretty funny with the odd clump of clay on the mesh. The farthest forward I saw any chips thrown was probably about 20 or so feet.

One stump was fun. Probably gets old if you have to do 20 that size.

Hey, less than 1/2 hour for an 18" stump 13" tall total sure beats a day with a pickaxe and shovel, right? ;)

I would guess that the 1850 stump grinder has a lot more power than the 422 one.
That's pretty fast on a stump. Is Ash a hardwood? Most of my experience is with Oak.

Ash is a hard wood - used for baseball bats. Makes a really good fire wood and it normally splits fairly well.

Yes, ash is definitely a hard wood. I'd guess that just as with woodturning, its easiest to work with wet green wood. Turning green wood is great, as you can peel off beautifully long shavings. If it dries out, then you can see sawdust, especially with dull tools. Of course, if you wait till it starts to rot, then it will get easy again.
