Hello to all members. Just got a very used Komatsu D21P-7 dozer and have tons of questions. About the only thing I know is that I really don't know. I listen to all advise because I love knowledge that others are willing to share. My true profession is in the private security industry. But I really enjoy working with my tractor and dozer. Sold my excavator to get the dozer. Just like equipment.
Welcome to HEF Sherman. :drinkup I haven't worked on D20 and D21 Kommies for some time, and I'm even less familiar with the dash 7, but if they're anything like the previous models with dry steering clutches, don't let it sit for long periods without working it to prevent the steering clutches from getting stuck.
