I took the Edge Tamers for a test drive today. The folks at R2 were kind enough to let me test drive some prototypes, they're just like the ones currently available except wider to hold up with bigger tractors. These are 6" wide.
To be blunt, I love these things. Using the bucket by itself would require tipping the edge back to prevent digging into the surface being cleared. That would result in the bucket filling with loose snow, then the bottom trying to push through but simply riding up on the snow. With the Edge Tamers, I can tip the bucket down so it tries to dig, but it can't dig into the ground. You can see the rear blade is angled narrow enough it's not doing anything, what you see cleared is all from the bucket. With it tipped down, the snow rolls forward like it would with a plow. The Edge Tamers essentially turn the bucket into a snow pusher. I shot a couple of videos, but they're pretty poor. A guy needs one hand to run the loader control, one to steer, a third for the reverser lever and a fourth to hold the camera. I'm two hands short of all that. I should be able to get a video with a helper this weekend, and may post the ones I shot today anyhow. Despite my poor videography, the Edge Tamers really shine.
Where the Edge Tamers shine even more is obstructions. I have to clear across a few cattle guards, and using the bucket or the rear blade you're almost guaranteed to hang a crossbar with it and stop the tractor. Not with the Edge Tamers. I lifted the front tires off the ground with the bucket and pushed across the cattle guard as easily as ever, and cleared more snow off in the process.
I really am thrilled with the Edge Tamers. We're going to try them out on the Ford 8210 that weighs 14,000 lbs and has an 8' bucket soon, but I expect them to work as well with it as they have for me.
