John Deere introduces enhanced dozers for underground infrastructure industry

(UI) — Improving its product portfolio of large dozer offerings, John Deere introduced the 950 P-Tier and 1050 P-Tier dozers as part of its performance tiering strategy. Previously in market as the 950K and 1050K, these robust machines are the next generation of models to join the increasing lineup of John Deere P-Tier dozers.

The new 1050 P-Tier dozer boasts an increase in engine power and a redesigned hood and front-end design. In addition, both the 950 P-Tier and 1050 P-Tier offer enhanced visibility and improved safety features, positioning them as an ideal solution for operators aiming to boost productivity and protection on the jobsite.

The strategic design enhancements of the new P-Tier dozer models aim to improve operator safety, visibility on the job, and uptime. Now equipped with standard LEDs, operator efficiency has been significantly improved during night-time or low-light operations. Also helping to improve uptime, the cold weather hydraulic lines are specially tailored for cold climate operations. These hoses, which replace the standard option, are rated for lower temperatures, ensuring smooth hydraulic function in harsh winter and weather conditions. The cab of the 950 P-Tier and 1050 P-Tier can be tilted for easy serviceability access under the cab.

Taking safety to the next level, the Operator Presence System ensures that an operator is present in the seat of the cab, with the seat belt fastened, before the park break can be released. This ensures a critical layer of safety, preventing accidental movement or operation before the operator is buckled in. The P-Tier system also integrates the park brake switch into the system status monitor, eliminating the need for traditional park lock levers. This integration not only streamlines the operation process but also enhances the overall safety mechanism of the machine.

Enhancing operator comfort and functionality, both models now feature a premium heated and ventilated seat option, which is air-suspended with adjustment controls for optimal ergonomics. The seat design remains at a 15-degree angle to provide optimal comfort when operating the rear ripper. The updated cab features new ergonomic controls, neutral counter rotate, and an integrated forward neutral reverse switch. This ergonomic focus ensures operators can work for extended periods with reduced physical strain, helping to enhance productivity on the job site.

Remaining the largest Power-Angle-Tilt (PAT) dozer in the market, the 950 P-Tier dozer features SmartGrade™, John Deere factory integrated mastless 3D grade control. This machine has the power for heavy cuts and the finesse to finish grade. 

Receiving a significant increase in operational advantages upon its entry to the P-Tier portfolio, the newly upgraded 1050 P-Tier dozer boasts a range of features and enhancements that boost overall functionality and efficiency. One notable upgrade is the tag link and blade design that brings the blade 10 inches closer to the frame. Along with the tag link, inverted tilt and pitch cylinders were added. The inverted tilt and pitch cylinders, lowered hood and larger front window help improve operator visibility to the blade. The repositioning of the 168-inch blade, due to the updated tag link design, paired with double-bogie undercarriage provides operators with a more balanced machine and a clearer view of the blade corners, which is a critical factor for precision work.

In terms of power, the 1050 P-Tier dozer features a revamped JD14 (13.6 L) engine which replaces the 13.5 L engine in the 1050K. The JD14 enhances durability, reduces fuel consumption, and uses a single canister in the aftertreatment system to meet emission regulations without the need for a diesel particulate filter. Lastly, on the 1050 P-Tier, the new cooling system has been redesigned with a single plane layout, positioning coolers side-by-side instead of stacked. This new design not only improves cooling efficiency but also simplifies access for cleaning.
