Wow is all I have to say. That looks great.

Looks good. Did you use a 1 to 1 ratio in the gearbox, or a step up ratio..

Very cool! Is it chain drive? How about the right angle gear box, what ratio is it? I'm also curious about the uneven spacing of the teeth on the grinder wheel.
:D

kruszert ,

Would you tell us a little more about the logic for the teeth placement.

Scotty - - - looks like we finished about the same time. You are a few stumps ahead of me. Good job!

My gear box is a speed increase type. Ratio is 1 to 1.46. Bought it on ebay and it seems to work - - - never can tell about stuff from ebay. I used a
#100 roller chain and sped up a little more, 17 tooth on the drive and 11 tooth on the shaft. Running the tractor around 2100 rpm (2400 rpm is used to get 540 at PTO) works best. I have found that the grinder has a tendancy to pull into the stump if you are taking too big a bite. It can bring the tractor to an immediate stop - - a little scary. Just like any new piece of equipment I am learning as I go. No damage done so far - - - except for stumps:).

As for tooth placement. I have 6 sets of angled Greenteeth (700 series)spaced evenly 60 degrees apart around the wheel. Then I have two sets of straight teeth 180 deg. apart. It shows in the picture and gives the impression of odd placement. I was told but the salesperson at Green Mfg. that the straight teeth were needed if I wanted to grind straight down into a stump rather than come from the side. I saw the same tooth placement on a Vermeer SG 252 so I figured I should do it too. Can't say that I have needed them but it was easy to drill a few more holes when the wheel was on the mill and would be difficult to drill later.

Thanks for kind words,
Reggie
