Dozer Ripper Loosening Production Rate

Bank cubic yards per hour a dozer ripper loosens in place from the shank spacing, penetration, and speed - the loosening step that feeds the push, load, and haul spread. Ripping fractures rock and hardpan; it does not move it. The operator judges rippability.

Formula and source

cross_section_ft2 = spacing_ft x penetration_ft; production_bcy_hr = cross_section_ft2 x speed_fpm x 60 x efficiency / 27 (60 min/hr, 27 ft^3/cy fold the units).

Swept-prism production identity by name (loosened volume = ripped cross-section x travel rate); first-principles unit-folding arithmetic.
