Not exactly a trenching bucket.

I wanted a 36" bucket for my TLB when I bought it, but now I think I'd like a nice 12" bucket. When I trench, I move a LOT of material. I wouldn't even consider trenching with that 36" monster. I think you'll get a lot of work done with that as long as you don't hit rocks or very hard soil. :thumbsup:
Nope, definatally not a trenching bucket unless you are laying some large tile
Or even doing "slinkey" trenches for a geothermal install.
And its not the best stump bucket either

because if you are digging out a measly 12" stump, you end up with a 7' hole: (36" on each side to break roots plus the 12" stump).
I am actually not sure if it is classified as a 36" though, because I am not sure how the measure them. It is 33" outside to outside and ~30" inside measurments. CNH lists a 30" and a 36", so I dont know which one this is "classified as".
Dads 4500 has what is called a 24" bucket and measures 21" outside. So I am "assuming" they are classified as to the size trench they would leave???????
I also dont know what the difference between a "trenching", "rock", "special duty" and just plain "heavy duty" buckets are????? CNH lists all 4 in varying sizes. I am not sure what I got? I know dads on his 4500 is open in the back where the pin bosses are and seems shallower than mine. Mine seems deeper and is solid on the back?? Forgive my ignorance, I am a newbie to backhoe ownership.
Anyone know the difference??
Idealy, I dont see a need for a 24" bucket but would like a 12 or 18. A 12" or 18" would be nice for trenching, and the 36 would be nice for VOLUME, like septic pits, a basement, small pond, etc. But if I had a 12" and 36" I wouldnt see a need for a 24.
