What exactly should someone be on the lookout for? I don't see too much danger in running a PHD ... but then again I may not be looking in the right place. )</font>

On of my farm magazines a few years ago had a big picture of 2 of it's reporters, one was shirtless. Kinda got people wondering about the direction of the magazine for a minute... /forums/images/graemlins/wink.gif

Anyhow, these 2 farm boys grew up around machinery, still farmed in addition to their writing. They were doing a story on fence building, and were taking some photos of the auger at work. It was not going into the dry ground, so one was pushing down on it. The pto caught his shirt, & ripped it off. In less than a second. The other guy happened to be clicking the auto camera at the time, & they had some _niffty_ shots of the shirt peeling off the guy. Thay made this into quite a safety story.

He said he had no clue what happened. He was looking around, trying to figure out why his shoulders were bare, etc. He said he was very lucky to have a light-weight shirt on, or the pictures would be very gruesome.....

Anything that spins with that much torque & momentum is likely to catch a string, shoelace, shirt-tail _some_ time & wrap it up tight.

Because phd appear to be slow moving they do not look all that threatening. Because it tends to be a community job with 2-5 people around, and because sometimes a phd needs a little oomph or push, and because these is fresh slippy dirt around, and... - there tend to be a very high number of accidents with one compared to it's hours of use. The injuries tend to be twisting & gruesome - either it doesn't catch you like 100 times before, or it grabs you this one time & does not let go - it just twists & breaks & slings you, at 100-500 rpm - that's almost 2 times around per second at the slow speed. Well, it _looks_ slow enough not to be dangerous, but think about spinning around that shaft 2 times every second until your friend gets the lever off.....

I got one 2 years ago, and don't let my wife or friends anywhere near it while I'm running it. They sure are welcome to help with the posts and all tho!

Gatorboy, do you have all the specs (displacement mainly)on that phd? I'd like to build one to match match my 24" bit. I've got a lot of trees to plant and my neck can't take it any more.
