[QUOTE="Yoby, post: 65025, member: 631"] So last year I pick up an old SnoLander 520 (6ft pto driven) snow blower to put on my 45hp yanmar tractor. Worked a couple kinks out last year just ensure I knew how to use it. But we never really got enough snow to truely test it. With the snow we got yesterday, I got up this morning and started blowing. I think we roughly got 4 inches.... Shouldn't have been too hard at all. I make my first pass from the shed to the house (~60) and sheared a pin. Odd, but maybe I snagged something. Get the pin replaced, make my first run from the house to the road (80 yrds). I get 10 ft from the road and shear another. Now I am just wasting time replacing pins and I have to get to work. Said piss on it I'll use the loader. So my question for anyone that is familiar with PTOs and shear pins. What size should I have? When I got it last winter, there we a keyed slot with a set screw for the shear. the shaft on the blower box showed signs of stress, so I drilled it out and put a pin in its place. I am thinking I have under sized it or have the wrong grade pin. Any thought are helpful [COLOR="silver"][SIZE=1]- - - Updated - - -[/SIZE][/COLOR] [ATTACH=CONFIG]3182._xfImport[/ATTACH] This is what I was using for my pin.
