will a L2800 handle a 84" snow bucket ....
I would think that it depends upon a few things:
1. What kind of snow are we typically attempting to move?
Heavy, wet snow might be a challenge if you're clearing a large area
2. How much
ballast / traction aid can we provide?
I'd have as much weight as possible on the back, and chain the rears regardless of tread-type (please don't let this degenerate into another tread-type discussion...)
3. How "big" is the bucket?
If it's a true "snow" bucket, it could be pushing 1 1/2 + yds in capacity, which when filled may be more than your loader can lift, depending again on type of snow
I haven't a clue what your tractor's weight is, nor what your loader's lift capacity is. Also keep in mind that the more weight you have tied up in the bucket, the less snow that can be lifted...
I hope this helps
