John Deere has 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, the new 1050 P-Tier dozer offers an increase in engine power and a redesigned hood and front-end design. Both the 950 P-Tier and 1050 P-Tier include enhanced visibility and safety features, including standard LEDs and cold-weather hydraulic lines.
These hoses, which replace the standard option, are rated for lower temperatures, improving 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.
The Operator Presence System ensures an operator is present in the seat of the cab, with the seat belt fastened, before the park break can be released, 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.
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 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.
As 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.
A 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 paired with double-bogie undercarriage provides operators with a more balanced machine and a clearer view of the blade corners.
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.
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.
