New Komatsu D51EXi-24 Bulldozer for Sale
If you need the “Swiss Army knife” of dozers that can adapt easily to multiple situations — from golf course construction to highway projects — this dozer is it. Built for precise, high-speed grading, its standard parallel link undercarriage system has rotating bushings, which help reduce undercarriage wear, especially while traveling in reverse at high speeds. And the new Tier 4 Final engine and electronically controlled hydrostatic transmission help keep fuel use remarkably low for a dozer this powerful.
Learns as it works: With proactive dozing control, even your less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Can improve productivity by up to 60% versus previous generation.
Spreads fill material automatically: Lift layer control automatically lets your operators spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over and uses the data it gathers to plan the next pass. Attain up to double your production and achieve consistent layers for compaction quality.
Levels material even during rough dozing: Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%.
Quick surface creation: Operators can create a temporary design surface with the press of a button. Combined with other iMC 2.0 functions, your crew can begin stripping or spreading using automated input while waiting for the finish grade model.
Close the operator skill gap: Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps lessen the skill gap between new and experienced operators.
Advanced machine control: In select situations — auto stripping, rough dozing, spreading, advanced finish grading — operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without having a 3D model.
A machine that learns from the operator: Automatic functions give the dozer the ability to learn from operator's blade input, resulting in more adaptability, easier operation and less reliance on operator input.
Outstanding blade response for finish grading: To deliver unparalleled grading performance, iMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly.
With iMC, you can:

Learns as it works
With proactive dozing control, even less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Productivity can improve by up to 60% versus previous generation.
Spreads fill material automatically
Lift layer control automatically lets operators spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over and uses the data it gathers to plan the next pass for up to double your production with consistent layers for compaction quality.
Levels material even during rough dozing
Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%.
Quick surface creation
Operators can create a temporary design surface with the press of a button with quick surface creation. Combined with other iMC 2.0 functions, crews can begin stripping or spreading using automated input while waiting for the finish grade model.
Cutting-edge automation and job site design
From automatic dozing, rough cut to finish grade, iMC-equipped Komatsu dozers help make every pass count and give you the potential for superior production compared to traditional aftermarket systems.
