The plow's trip-edge, outboard reversing cylinders and reinforced pivot points combine for performance outside the norm for medium-duty snow plows, according to Hender- son. The MTP's level-lift holds a level position throughout the reversing cycle, keeps the plow low and out of the operator's line of vision (at all times) and holds the plow high enough to avoid digging into roadways while not in use.

At the tip end, the Road Razor ECO's proprietary point design is combined with Kennametal's advanced carbide grades and higher head hardness, results in less cracking and longer performance in even the most abrasive asphalt conditions. Moving down the tool, a unique and proprietary, thicker, nonagon- shaped washer, extends the life of the toolhold- er allowing maximum tool life. The nonagon design with overhanging corners also makes cutting easier by encouraging tool rotation. At the retainer end, thicker material ensures exceptional fit and rotation throughout the life of the tool.

The ZX210LC-5's undercarriage is 12 inches longer than the 210 and supports a greater lifting capacity. The Isuzu AI-4JJ1 diesel engine used in the ZX160LC-5 generates 121 horsepower; the ZX210-5 and 210LC-5's Isuzu 4HK1 engine generates 159 horsepower. The engine employs cooled exhaust gas-recirculation (EGR) platform paired with a diesel particulate filter (DPF) to meet EPA IT4/EU Stage 3B emissions regulations.
