Looks just like the Landpride I bought recently. One thing I did to mine was I punched a hole in the rubber deflector flap at the end and added a threaded screw eye so I can keep the flap up with a rubber tarp strap. I don't care if it flings stuff out the back because no one is behind it anyway and the flap tends to get into the cutter wheel. With Greenteeth you have to also have the the tooth mounts attached to the wheel. I could have sworn the one I bought at auction had Greenteeth and the mounts but that was a while ago so you may be right.
It certainly gobbles up stumps. My issue is, neither of my tractors are HST so what I do is, I rotate the bucket down with the cutting lip on the ground, put the tractor in neutral and use the bucket curl to advance the stump cutter, always being mindful that I'm way overpowering it. The LP is rated for 60 horses but I have just under 100 pto. Only thing I don't like is on a really big stump, I have to cut it in 2 passes and I have some big ones. At least I have no rocks to deal with, it's all sandy loam here.
Did 20 or so, so far plus another 15 for a customer up town. Hers was mostly pine so it was quick. Mine are mostly hardwood with some maple.
I'd really would have to purchased a Rayco self propelled unit but they are just way beyond my where with all, even used and beat.
Set the slip clutch pretty loose, just in case.
A new Shaver is around 10 grand. The LP was 5 grand new.
Don't know about yours but with the LP you need 2 sets of remotes. One set for the swing and one set for the elevation and both sets have flow control valves to modulate the movement.
35 grinds so far and no wear at all on the Greenteeth plus you can index them to 3 positions before they need ground or replacement. Done some really big stumps too.
I will say one thing and that is 'spectators' are not allowed. That thing is wicked.
I'm embarrassed to admit that I hadn't actually looked up the Landpride and Erskine units prior to now, I was just going by memory when I typed my original reply to your comment. However, I just took a few minutes to look them up. They are not even close to the Shaver SC-50, it's in a different league altogether (unless I'm looking at the wrong Landpride). In fact, the Erskine looks quite a bit more heavy duty than the Landpride, sort of in between the the Shaver and LP.
Is this the model you have?
Land Pride
If so, I'd almost be worried about using it on your 100hp tractor. It's rated for barely more than half your hp. You should trade with me, the Shaver is rated for 100hp tractor, and I only have 39!
A few not-so-small differences....
Landpride cutting wheel is 1/2" thick and 24" diameter
Shaver 50 cutting wheel is 3/4" thick and 34" diameter
The weight alone is staggering, 540lbs for the Landpride vs 1,144 pounds for the Shaver! These two are far from comparable.
Of course they will be vastly different in price.
The Erskine looks like a nice option though, probably cheaper than the Shaver but more than the Landpride, and right in the middle as far as 'heavy duty' goes.
The 3-Point Stump Grinder is mean to the stump but kind to your tractor.

Regardless, the stumps don't know the difference, they grind just the same no matter what brand name is on the side of the grinder!
