Using a 65.5-horsepower Tier 4-Final engine, the Komatsu PC88-MR-10 hydraulic excavator is designed, says the company, to bridge the gap between compact and construction-size models. The “tight-tail” design and the swing-boom feature, says Komatsu, allows the PC88MR-10 to work in confined spaces. The new models has an operating-weight range between18,739 and 19,290 pounds and a maximum digging depth of 15 feet 2 inches. The standard auxiliary hydraulic system produces a flow of 33 gpm and can be changed from single-direction flow to bi-directional flow, depending on the requirements of the attachment. Standard equipment includes a bucket-thumb-mounting bracket, auxiliary piping for attachments, and a 7-foot-7-inch blade that is available with a power angle blade option.
