Stump bucket V2 is very heavy duty for sure however unfortunately it is very sloppy in my SSQA on my Caterpillar 257B3 MTL. One of the Quick attach Pins almost completely separates from the attachment and this was just me testing the attachment without putting any pressure or actually working the attachment. Not sure what can be done other than fabrication fo the attachment so that it's solidly mounted. I saw this on other reviews from many months ago but figured it was resolved by now. I'll be calling Customer support about it as i shouldn't have to pay for welding and fabrication on a new unused implement
