    This is my 2nd year with he 810 and this year she is getting a workout! It seems like we get a new snow storm about every week or so. There not big one, some were only 1" or so and very fluffy snow on mostly dry pavement. So the cutting edge is getting a workout. Without looking at the manual, how much of the cutting edge should be left before it must be replaced?

    most will say when it is within 1-2" of the main mold board

    really its as soon as the edge is no longer productive...why fix something that still works?

    Well, it's time then. It was about 2" a week ago, but with all the snow it's down to about 1" now and both wing cutting edges have broken. We got 6" yesterday and now look like another bigger storm in the next few days. Man, I haven't got much sleep in the last 3 days, but I'm loving it.

    Replace the cutting edge just before you start wearing the moulboard. With my 810 I got down to about 3.5 inches of cutting edge left when it had to be replaced.

    Another consideraton is if you back drag much. I would think at least 2" below mainboard is needed if you want an effective back drag. Otherwise you could probably go down to 1" or so if you mostly forward push.

    Ya, Mine got down almost to the mouldboard the first time before I changed it. I would run it pretty low. I get about 1.5 seasons out of my cutting edges.

    Run it all the way down to just before the moldboard. They cost $500.00 installed. Make sure you get your moneys worth.

    Exactly. If mmory serves me correctly, they are about 6" high in total and 2" of that is above the bottom of the plow - leaving 4" below. If you change it out after 2" of wear, you only used 50% of the edge. I have seen mine drop 1/2" in a week

    my opinion

    I look on the back side of the plow at how much cutting edge is left from the plow itself and using i will go until its about half an inch to a inch depending how even it is from side to side

    another money safer for you 810 guys I went to a metal shop had them get me a cutting edge and drill the holes to match up and also had them get me 3/4 inch instead of 1/2 and I put that on the plow then put the wings out staight on a level surface then measured the wing cutting edges took my main cutting edge cut that into peaces the same as my wind edges and welded the old cutting edges to my wings just so it lined up all the way across. that saves from buying all new cutting edges and the thicker main cutting edge last longer being thicker

    Do you guys run shoes on your 810's. My blade was new in December and I have about 1/2" - 3/4" of cutting edge left:D I was wondering about putting the shoes back on to help with the wear on the cutting edge.

    Check out www.winterequipment.com and look at the extendor for smaller trucks. These carbide pieces will give you much more edge life.
