SPECS SUMMARY

Base Power (1st Gear) – Net	304 HP (227 kW)
Operating Weight – Typically Equipped	74324 lb (33713 kg)
Blade Width	18 ft (5.5 m)
Engine Model	Cat® C13

The 18 builds on the success of the 16M and offers additional power, a wider moldboard and the possibility to use a more aggressive blade angle, making it an ideal fit for mining operations that run 172-tonne (190-ton) or smaller trucks. The 18 enhances operational efficiencies by increasing coverage and reducing the number of passes required to complete the width of the road in certain applications. The 18 includes features that provide large benefits on operating cost reduction, uptime & performance improvements as well as enhanced safety.
