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, these machines are the next generation of models to join the lineup of John Deere P-Tier dozers. The new 1050 P-Tier dozer offer engine power and a redesigned hood and front end.
In addition, both the 950 P-Tier and 1050 P-Tier have visibility and safety features, positioning them as a solution for operators on the jobsite.
“John Deere is dedicated to providing its customers with large dozer options that fit the needs of every job site, and the new P-Tier machines offer the durability and reliability our customers demand from machines of this size class”, said Matt Costello, product marketing manager, John Deere Construction and Forestry. “The 950 P-Tier and 1050 P-Tier dozer models were updated with the customer in mind, helping them increase efficiency, visibility, and gradeability in even the most demanding conditions.”
The design of the new P-Tier dozer models aim to support operator safety, visibility on the job and uptime. Now equipped with standard LEDs for night-time or low-light operations, the machines feature cold weather hydraulic lines tailored for cold climate operations. These hoses, which replace the standard option, are rated for lower temperatures for hydraulic function in harsh winter and weather conditions. The cab of the 950 P-Tier and 1050 P-Tier can be tilted for serviceability access under the cab.
For safety, the Operator Presence System keeps the operator present in the seat of the cab, with the seat belt fastened, before the park break can be released. This serves as 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.
Both models feature a heated and ventilated seat option, which is air-suspended with adjustment controls. The seat design remains at a 15-degree angle supporting rear ripper operation. The updated cab features new controls, neutral counter rotate and an integrated forward neutral reverse switch.
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 ability to finish grade.
The tag link and blade designs have been upgraded, bringing the blade 10 in. 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 large front window help with operator visibility to the blade. The repositioning of the 168-in. blade, due to the updated tag link design, paired with double-bogie undercarriage provides operators with a balanced machine and a clear 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 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 supports cooling and simplifies access for cleaning.
