This new bucket replaces the first version and offers many improvements to the original design. Just check out the plasma cut teeth that have been added, this model replaces the flat surface of the previous stump bucket! They have also developed the Wicked Stump Grapple, for those of you who need the toughest attachment made! Good Luck Stumps, because we are going to be selling a lot of these skid steer stump buckets and skid steer stump grapples in the near future, and your days are numbered.
More about the "Wicked" Stump Bucket for Skid Steer Loaders
From Corey Sheets - Engineer - Construction Attachments
The unit you see in the picture is a 1SBGSXD50 Wicked Stump Bucket Xtreme Duty. That is a stump bucket with grapple, severe extreme duty, with a 50” clam opening.
To see how anyone else stacks up against this new stump bucket, you will need to know that the "Wicked" Skid Steer Stump Bucket specs on the moldboard, sideplates, and bottom, as well as, the rest of the bucket body parts are of 3/8” A572 plate steel. The side cutters are actual ½” X 4” 1065 milled cutting edge material that has been CNC PLASMA CUT for the teeth.
Using the hard milled cutting edge material gives these side cutters the ability to cut, as well as, grab. This should be a decided advantage over comparable stump buckets that have merely had teeth cut into the hot rolled steel sideplates. The flat cut teeth on the competitor’s models may grab, but it will be more difficult to drive them through roots. I have ¾” A572 on the grapple arms and ¼” cap plates that are broken out as you can see in the photos with a ¼” doubler with teeth at the front of the grapple. The grapple caps are reinforced by 2”X2”X1/4” tubing and 2”X3”X1/4” tubing. Pivot pins are 1 ½” on the grapple and 1 3/16” on the cylinder.
The skid steer stump bucket teeth cut into the grapple arms are in line but at an angle to the flat runs of the grapple arm to help them to get a bite. They are aggressive and should bite very well, but they are only cut in pockets of teeth instead of along the entire arm, so that if you get more bite than your skid steer can handle you can roll forward and open the grapple to release and get a more advantageous angle or simply disengage from the stump.
The folks I have talked to seem to be looking at this as a beast of an implement for the more robust machines, but I would point out that the smaller skid steer loaders on rubber tires may need the grapple as much or more than the large track mount machines. The smaller skid steer machines with less ground weight and traction have a harder time using the stump bucket with no grapple because they don’t have the weight, horsepower and traction to drive into a stump and cut enough roots to pop it out of the ground as well as a more robust track machine. Using the skid steer "Wicked" stump bucket grapple to snap off the stump while the skid steer stump bucket teeth are indexed at the roots is a way to use the hydraulics, where these machines have plenty of available power, to get the same work out of the smaller rubber tire machines.
