    Hi all,

    My dad passed away in November 2007and I am left with the plowing duties... We have a 1999 Dodge Ram 1500 with a 7.5' Fisher Plow on it. No Ballast (which I think I might do something about after plowing in last nite's muck - Northeast PA).

    Anyway, here's what I plow:
    1.) 225' long blacktop driveway - mom's house
    2.) 225' long modified/gravel driveway - our place
    3.) 50' long by about 30' wide parking area at a mobile home my mom rents out - gravel/modified

    No plow shoes (My dad was a maintenance manager in a community for 25 years and plowed with big and small trucks without them on modified and rolled tar/chip roads and that's how I learned. Pay attention, keep your hand on the control and adjust the blade as needed).

    Before the 2007/2008 season, we replaced the cutting edge. 6" x 1/2" (he had it on order before he passed away).

    My question is, how long do plow edges last? This looks to be in good shape and on blacktop still gets down well (frankly, I don't want to scrape right to blacktop and put scratches in it causing sealing coating to be done more often to make it look nice, but not sure if that's just me or the right way). What should I be looking for as far as wear? Do you just buy new or can I sharpen somehow?

    thanks!

    the sharpening will be done by the asphalt, till at one point there is no more blade left and then you order a new one. asphalt moves up and down with freeze/thaw, scratches will happen, its only a driveway.
    oh and you'll probably get 6 years with what you plow.

    Ok thanks. I don't know specifically how far below the plow edge itself the 6" cutting edge hangs. Is there some normal amount of overhang? i.e. when the X inches are gone and the cutting edge is flush with the plow edge itself, go get a new one.

    fisher's web site can let you know exactly but you can wear down to about an 1" below the welds holding the bottom of the springs.

    Ok I have to look at some things on our plow. I swear my cutting edge is flush with the edge of the plow right from new but that can't be right. But your pictures definitely help. thanks!

    when you buy a plow new and it comes with a cutting edge (you can run fishers without a cutting edge) the two will be flush with each other, when you have worn down the original to about half of its original width you unbolt the factory replaceable cutting edge and put your new one on. It is advisable to use new bolts, the old ones are stressed so just buy a pack of replacements from fisher. the new edge will now overhang the tripedge by about 2-3".

    Ok I'll take a look when I start plowing today. I do know we used new bolts when we replaced the edge in 2007 because I pulled out the receipt to check. thanks!

    Not the greatest picture but it looks like there's a bit more than an inch on the cutting edge below the trip edge (it's at an angle) so I guess I'm still good for a while.
