APT Hammers and Breakers combine flexibility with hard-hitting power. The MH11 pick hammer is designed for horizontal work in renovation, demolition, and structural alterations, while the MH 55 (medium-weight) and MH 70 (heavy-duty) multipurpose breakers are ideal for road building and maintenance on asphalt, brickwork, frozen soil, or concrete.
Features:
Slim design for excellent line of sight to the working tool
Quick-release couplings for fast connections
No external side bolts or protruding parts
High-back pressure (HBP) models can be operated from the PTO outlet of most skid steers
Vibration-reduced (A) models offer the same breaking performance with additional operator comfort

** At delivery MH55/MH55A are supplied factory set to 8gpm (EHTMA D). There is a plastic bag in package with a label and restrictor nipple that should be mounted on the tank line (T) if there is a need for the breaker to be set to 5 gpm. The size of the orifice is tamped on the the nipple.
Now you can use your skid steer, backhoe, excavator, or tractor to power your breaker. These tools are designed to work with high back pressure and represent a breakthrough in versatility.
These units are able to work on a maximum return/back pressure of 508psi (200 psi for non-high back pressure units)
Flow requirement of 8 gpm (Same as non-high back pressure units).
Working pressure at approximately 1668 to 1885psi with maximum relief valve setting at 2200 psi. (Same as non-high back pressure units.)
To ensure the tool is receiving the correct flow of 8gpm, you will need OFD8 (1801164319). Max flow in: 32 gpm; Max pressure: 360psi
No warranty for tools damaged by over-pressure when run without an oil flow divider.
**For John Deere and Bobcat Skidsteer that deliver between 16 and 30gpm - pressure reduction hoses must be used in conjuntion with the OFD
