The appropriate number and width of Edge Tamers depends on several variables, including the weight of the tractor and the width of the bucket. The following are rough guidelines:

• Up to 24hp (usually ~48" bucket), two 3" wide
• Up to 30hp (usually ~60" bucket), two 4" wide
• Up to 50hp (usually ~72" bucket): three 4" wide
• 60hp+ or 84"+ bucket: two or three of the 6" wide
• Skid steers with single cutting edges: four 4″ units
  

Note

These are rough guidelines; for example if pushing snow on a gravel driveway with a large crown, you may want to have an Edge Tamer in the middle of the bucket in addition to the ones on each side, to avoid digging into the crown. Further, for especially soft or saturated ground, conditions may require an additional Edge Tamer. 

On the buckets we have tested, the product fits without a problem. For the 3" and 4" Edge Tamers, the opening on the back of the Edge Tamer is 1″, which should be plenty of space (for the 6", it is closer to 1 7/8"). You may note in the pictures how much space is available. One exception are buckets with removable, bolted-on edges. The combined thickness of those edges can be more than 1", and therefore incompatible with the Edge Tamer. If you are especially concerned about a fit, here is a 3"/4" template and a 6" template you can print out to compare, along with instructions. The instructions contain important information about proper printing and making the template easy to use. 

We do it just as a demonstration. We are showing that the Edge Tamers alone are doing the work of moving the material while not digging into the ground. In regular use, this is not necessary. The most important thing is to make sure your bucket (and the Edge Tamer) is flat on the ground. If float mode is available for your tractor, this can help as well.

While we cannot guarantee compatibility, our customers have found them to work well together. We have never had a return due to non-compatibility. The following post by a customer is a useful reference:

Not at all! They install install in seconds with the turn of a 3/8″ ratchet with 3/4″ socket.

We suggest a 300 pound limit per Edge Extender. This means if two Edge Extenders are used, and the weight is equally balanced, a 600 pound capacity is reasonable.

No, but depending on the quality/age of the paint and the amount of tightening, some marking may occur on the inside of the bucket, but no more than can be expected from the normal day-to-day bucket use.

Yes! But only those with single cutting edges, and we recommend four 4″ units for proper performance. We consider a single cut edge to mean a factory welded edge that is not replaceable (i.e. a non-bolt-on edge).

In cases where this occurs, simply placing a provided 3/8″ washer between the bucket and the bolt will prevent this from happening, without affecting performance. We show you how in these instructions.

We provide the washers in case the Edge Tamer wants to twist when you install them. For more information, see the instructions.
