John Deere: How hydrostatic transmissions changed crawler dozers

Experts from John Deere recently shared with Equipment World how the hydrostatic transmission revolutionized the crawler dozer. Deere put the first dual-path hydrostatic dozer on the market in 1976, and today every single one of its crawler dozers boasts a hydrostatic transmission, including the 335-horsepower, 77,000-pound 1050J. According to the official John Deere website, these machines offer operators increased speed control, with dynamic braking and live power turns.

"If you are set at a speed and encounter a change in the load, the operator doesn't have to do anything to downshift," John Deere crawler dozer product marketing manager Mark Oliver tells the source. "The machine will automatically manage the power to maintain that load. When it comes to live power turns, if you have a full blade of material you don't lose performance in that turn, and that's very important."

The hydrostatic transmission can also make tasks like pipe-laying far safer, because it allows for smoother and more precise movements. When your team is literally down in the trenches with the pipe, jerkiness on the machine's part could cause serious injuries.

While there is a lot to be said for John Deere crawler dozers with hydrostatic transmissions, it is also true that these machines don't run cheap. The good news is that you don't have to make this kind of major investment in your construction company very often -- these dozers are built to last.
