STANLEY Infrastructure knows what you look for in a small mounted breaker, that’s why our MB series focuses on simplicity, easy maintenance, and powerful breaking performance. All MB breakers have only two moving parts – which means better performance and less frequent service intervals. At the lower end of the housing, we added steel reinforcement to not only protect the housing, but to protect the power cell and keep operators running longer. A superior valve design allows for a wider range of pressures and flows. lowering stress on components. Plus, the light tool weight contributes to a broader carrier range.
Features:
•Advanced breaker design technology for output energy and efficiency.
•Minimal moving parts, only two for less maintenance, better performance and less service.
•Superior valve design for operation within a broader range of pressures and flows with less heat and stress on components.
•Added steel reinforcement at lower end of housing to protect housing and power-cell.
•Side-plate bolt locking system keeps bolts from loosening.
•Lighter weight allowing choice of smaller carrier.
•Supported power-cell by rubber cushions and urethane wear plates to absorb shock and vibration and reduce wear - MB556
•Direct acting nitrogen chamber boosts the power of each hammer blow.

BIG DAVE
Stanley can be a little tough to figure out what you want to order. The support documents and sales team are not much help. Let me take a stab at it and make a few comments.
- MB156 (175 ft lb energy class) very small hammer, up to 2500 lbs. loaders and 2000 to 4000 lbs. excavators. 4-10 GPM hydraulic flow range, Mini loader mount are not in the price book.
- MB256 (350 ft lb energy class) very small hammer, 2500 lbs. to 4500 lbs. loaders and 4000 to 9000 lbs. excavators. 9-16 GPM hydraulic flow range, Mini loader mounts are not in the price book
- MB05 / MBF5 (500 ft lb energy class) common size skid steer hammer, 4000 lbs. to 8500 lbs. loaders and 4200 to 12500 lbs. excavators. 10-22 GPM hydraulic flow range, All the specs read the same between MB05 and MBF5 I am not sure why there is a different model?
- MB556 (750 ft lb energy class) common size skid steer hammer, 4200 lbs. to 9000 lbs. loaders and 4500 to 12500 lbs. excavators. 12-22 GPM hydraulic flow range.
- MB10 (1000 ft lb energy class) common size skid steer hammer, 4200 lbs. to 13500 lbs. loaders and 8500 to 19500 lbs. excavators. hydraulic flow ranges are not listed in any of Stanley's information.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.

Perfect for active dogs
This is a must-have if your dog loves to fetch. It throws the ball far with very little effort and keeps your hands clean—no more slobbery chuckit balls.
Lightweight, durable, and makes playtime much more fun (and less tiring for me!).

Way better than the M size for us
Like most people that have dogs I first went with the M size or Tennis ball size (about 2.5") chuckit for my 65-70 lbs Lab. After having that for a while and my dogs' evolution from liking to chase the ball to wanting to catch it, I started seeing how the M size could cause some life threating problems for my pup. I was on the fence for several weeks when I came across this option that included a 3" ultra ball as well as a 3" fuzzy tennis ball like ball. These balls can fly so much farther with less effort and my furry friend seeming to like them more than the 2.5 inch. It also seems to fit their mouth better allowing them to enjoy 'the game' (you lost by the way) much more.
If you have a larger dog or your dog has a big mouth, please trust me when I say skip the 2.5" M size balls. You and your dog will haves much more fun with this 3" size
