Hydraulic hammer attachments
The John Deere Worksite Pro HH20C, HH40C, HH60C and HH80C hydraulic hammer attachments are optimized to work with select John Deere G- and E-Series skid steers and compact track loaders, G-Series compact excavators and most competitive models. A simplified hydraulic-breaker design boosts productivity and these hydraulic hammers provide two to three times more blows per minute (bpm) than previous models. With 30 percent fewer parts, rebuild times are reduced to one hour vs. eight hours, and an exclusive tool retention system enables quick installation and removal using only one small screwdriver. The hydraulic hammers only require grease every two hours of operation and have a 1,000-hour service interval, contributing to lower daily operating and maintenance costs. Five bit options are available on the hydraulic hammers to further improve operator productivity.

Box blade for finish grading
The Cat AccuGrade-ready BB124 box blade is designed for grading and leveling of large commercial properties, housing pads, roadways and parking lots. Using GPS and laser technologies, the attachment can quickly grade to within ¼ inch of grade, reducing concrete needed to finish the project. Front and rear curved moldboards allow flowing material to easily find low spots and improve grading and leveling performance. Dual parabolic mirrors provide full visibility to the front cutting edge so the operator can identify how much the blade is loading and see out to the corners of the box blade. Dual front wheels are mounted on an independent axle and on casters to provide stability in both directions of travel.

On-grade concrete drills
E-Z Drill’s line of on-grade concrete drills includes two easily positioned models that drill to a standard 18-inch depth. The models 210B and 210B-2 feature a compact frame, allowing each to operate within a 4-foot area. The units have been designed for straight-line drilling on a level subgrade and are ideal for airport work, lane additions and large patchwork jobs. The single-gang Model 210B can operate within 6 inches of a corner and drill a 3/4-inch hole 9 inches deep in about 15 seconds. The Model 210B-2 also drills within 6 inches of a corner and provides an inexpensive option for a two-gang system. Both units are totally pneumatic, with the 210B requiring 100 cfm and the 210B-2 requiring 200 cfm. An optional vertical conversion kit enhances the series’ versatility, allowing each unit to switch from a horizontal to a vertical drill in just 20 minutes. Quick-release bit guides work with any style of bit for a fast, simple exchange, while vertical height adjustment levels enable each unit to drill on-center whether the slab is 6 inches or 24 inches thick.

Walk-behind concrete power trowels
Atlas Copco’s three new walk-behind power trowels — the BG 245, BG 375 and BG 475 — include upgraded features that enhance versatility and safety on a variety of applications, from fine-edge to rough-surface concrete finishing. The units can be equipped with either a twist pitch or quick pitch for optimal performance on a wide range of jobs. A QuickStop feature stops the blade rotation immediately after the operator releases the handles. This results in zero-degree spin that minimizes the risk of injury. Without killing the ignition when the trigger is released, it allows speed adjustment without damaging the belt and clutch. The BG trowels are equipped with Honda gas engines that deliver 5.5 to 9 horsepower that offer variable speeds for a variety of tasks, from high-speed burnishing to low-speed, high-torque floating. The units have a palm trigger as well as foldable de-vibrated handles for enhanced comfort. Their detachable throttles can be moved from the left handle to the right, for comfort and ease of use for left- and right-handed operators. The units also have a stand to ease maintenance chores.
