Features
No DEF? No Problem
The 450 P-Tier Dozer boosts uptime and simplifies maintenance by removing the diesel exhaust fluid (DEF) system and extending hydraulic oil change intervals to 4,000 hours. It also improves hose routing to reduce leaks and uses easy-access spin-on filters.
Grade Control Solutions
John Deere precision construction technology enables operators to make accurate grading passes while significantly reducing re-work. The best part, our machine technology can be upgraded at any time, from entry level to advanced, now you have the flexibility to upgrade when the time is right.
Enhanced Cab Comfort and Visibility
The cab design is upgraded for improved visibility and operator comfort, featuring a larger space, heated and ventilated seats, LED lighting, and a rearview camera, compared to previous models. Operators benefit from better ergonomics and a more comfortable working environment, aiding productivity
