Been comparing specs across a few sites lately, and the 2021 Komatsu D61PX keeps showing up as a solid balance between power and control for mid-size earthwork. What stood out is its low ground pressure setup, which makes it great for softer ground - something a lot of the heavier rigs struggle with. While checking around, I found a few clean listings on https://www.boomandbucket.com/equipment/bulldozers , and the machines weren’t just sitting pretty in photos - they came with full inspection details, hours logged, and maintenance history. A couple even had grade control systems already wired in, which saves a chunk of time and budget down the road. If Komatsu’s your direction, that platform’s worth a scroll.
