I would think where 802Driver mounted his would be better in my own opinion. If they are in the center, instead of up front closer to the cutting edge, i would think that where he mounted them would help keep the bucket more stable front to back. I dunnoooo, i`ve never seen those type used on a bucket before. Hopefully 802Driver will report back on how it works out. Maybe 2 sets of them then... front AND rear of the bucket. I`m thinking that if you get them to close to the front cutting edge, whats going to happen if you need to dig down to remove hard packed snow and ice. At least when mounted in the center, it still gives you the option to use the cutting edge of the bucket, but not so much if the cutting blade cant get low enough to scrape when needed.
On an older tractor i have, i used those nylon tunnel protectors that they use on snowmobile`s. Every two years, i would unbolt them, attach a new pair cut to proper length. They were cheap, easily replaceable, then throw the old ones away.
I just cut some angle iron to length, bolted onto side of the bucket, then bolted the tunnel protectors to the angle iron. I left the length just short of the back of the cutting edge so that i could still use the cutting edge to break up hard packed snow and ice. I think i had around $25/30 bucks in the total bucket mod back then.
Here is a link to the tunnel protectors i`m talking about. There are lots of different ones out there, i just grabbed this link real quick to point out my comment.
