Mobile Diesel Repair for Bulldozers
Bulldozers are critical for site prep, grading, and land clearing — but Texas heat, heavy loads, and tough terrain take their toll. Instead of hauling your dozer to a dealership and losing days of productivity, our mobile diesel mechanics bring the shop to you.
We service all major makes and models of bulldozers, including:
Caterpillar (CAT D Series) – D6, D7, D8, D9
Komatsu – D39, D65, D85 models
John Deere – 450K, 700K, 850K dozers
Case – 1150M, 1650M, 2050M models
From small dozers working subdivision projects to large crawlers handling oilfield and highway development, Lone Star Diesel Solutions keeps your machines running strong.
👉 We also provide bulldozer repair for farm & ranch operations and oilfield projects. Visit our [Farm & Ranch Equipment Repair] or [Oilfield Equipment Repair] pages to learn more.

The Cost of Bulldozer Downtime
A bulldozer breakdown doesn’t just stall one machine — it stalls the entire project. Studies show construction equipment downtime can cost contractors $3,000–$5,000 per day in lost productivity, labor delays, and missed deadlines.
Our on-site bulldozer repair cuts downtime by as much as 70%, keeping your crew on schedule and your project on budget.
