Verified model comparison
A configuration-sensitive dozer shortlist: assess blade work, machine-control equipment and mobilization before interpreting the headline figures.
Write down material, push distance, finish tolerance and access limits. These candidates need not be equivalent in every weight or power configuration. Use the figures below to identify the actual builds being compared, then decide whether either machine is unnecessarily large or lacks the required working capability.
The D51PXi-24 record identifies an intelligent-machine-control configuration. On a used example, verify that the installed hardware operates and that required software, project data and support arrangements are available. Apply the same equipment inventory to any grade-control package offered on the D5; a model badge is not a list of included options.
Check blade dimensions and position, shoe width and track gauge against the intended ground and transport. Test blade control under load and measure undercarriage wear. Ask for repair and mobilization quotes on each actual configuration so that the comparison reflects the machine you can put to work.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.
