🚜 Dozer Production Calculator

How Dozer Production is Calculated

Production depends on blade capacity, cycle time, material type, slope, and operator efficiency. The biggest variable is push distance — doubling the distance roughly halves production.

Cycle Time Formula

Approximate cycle time = (push distance ÷ 200 fpm loaded) + (push distance ÷ 400 fpm return) + 0.3 min gear change. Actual speeds vary by machine and ground conditions.

Material Load Factors

• Loose soil: 1.0 — full blade load
• Gravel: 0.9 — slightly harder to hold in blade
• Compacted soil: 0.8 — harder to cut, less blade fill
• Wet clay: 0.7 — sticks to blade, reduces capacity
• Blasted rock: 0.6 — irregular pieces, blade can't fill completely

Slot Dozing vs Open Dozing

Slot dozing (pushing in the same track) builds windrows on the sides, reducing spillage. It's 20-30% more efficient than open pushing. This calculator assumes open pushing — add ~25% for slot dozing operations.

Typical Daily Production

• Cat D6, 150ft push, loose soil, level: ~700-900 cy/day
• Cat D8, 150ft push, loose soil, level: ~1,200-1,600 cy/day
• Cat D10, 150ft push, loose soil, level: ~2,400-3,200 cy/day
• Uphill pushing cuts production 20-40% depending on grade
