Among John Deere's Crawler line of equipment, the largest in terms of horsepower is the 1050K Crawler Dozer. This machine features a 13.5-liter PowerTech PSS 6135 engine capable of producing 350 horsepower. It also features a dual-path hydrostatic transmission, a multifunction LCD monitor to track performance, and three blade mount options to provide a flexible blade angle.
The smallest of John Deere's Crawler line is the 450J Crawler Dozer, which produces 70 horsepower via a 4.5-liter PowerTech M 4045 engine. As opposed to the 1050K's robust LCD-display reporting mechanism, the 450J features a less intricate display panel capable of relaying important information to the operator. The 450J has an optional Integrated Grade Control that allows "plug-and-play" electronic grade control using GPS or laser technology.
The mid-tier 655K Crawler Loader features a 6.8-liter PowerTech PVX 6068 engine capable of generating 145 horsepower. Viscous cab mounts and rear acoustical glass protect the operator from noise and vibration, making the cab more comfortable.
