How Long Do Bulldozers Last? Lifespan, Maintenance, and Key Factors

[TrucksSavvy009]

Hey everyone,

I'm looking into buying a bulldozer and wondering how long they typically last before major repairs or replacement become necessary. I know factors like brand, maintenance, and workload play a big role, but what’s a general lifespan for a well-maintained dozer?

Some specific questions:

• How many hours can you expect from a bulldozer before significant wear sets in?
• What maintenance practices help extend the lifespan?
• Do certain brands or models tend to last longer than others?
• At what point do repairs outweigh the cost of replacing the machine?

Would love to hear from anyone with experience in heavy equipment longevity!

A well-maintained dozer can easily push past 10,000 hours, and I’ve seen some old Cats and Komatsus still chugging along at 20,000+ with engine rebuilds. Regular undercarriage maintenance is a game-changer since that’s where a lot of the wear happens. As for repairs vs. replacement, it all depends on how deep your pockets are. Some guys swear by keeping a solid machine running, while others trade up once the repair bills start looking like a down payment on a new one! What model are you looking at?

Great points! If you stay on top of maintenance, you can definitely hit that 10k hour mark, sometimes even more. A lot of guys I know swear by regular oil changes and staying ahead on the tracks and undercarriage, they’re the first to wear out. And yeah, brands like Cat, Komatsu, and John Deere have a reputation for longevity, but it really depends on how hard the machine’s worked. As for replacing vs. repairing, if you’re looking at a dozer pushing 15k hours with high repair costs, it might be time to weigh the trade-in value. Anyone here replaced a dozer after a major breakdown?
