INTERIM TIER 4 CRAWLER DOZERS: New Engines on Four Models Meet Emissions Standards

摘要

John Deere has added four new models to the K-Series of crawler dozers. The 550K, 650K, 700K and 750K crawler dozers feature interim Tier 4 emissions-compliant engines using EGR technology with exhaust filters. The Deere engines are also able to maintain adequate oil flow to machine systems when operating on slopes up to 45°. The K-Series also features changes to the operator cab, including greater visibility of the blade and reduced noise levels.
