Why can a meat grinder's rated output differ greatly from actual output?

Catalogue throughput figures usually come from a specific meat temperature, plate size and feeding condition, so colder meat, larger pieces or sinewy trim can slow the auger and widen the gap on your floor. Have the maker state those test conditions, then trial your own or equivalent material to see sustained net output. When comparing quotes, align temperature, plate and net-output method rather than trusting headline numbers. For this machine, sign off on measured net throughput and cycle pace, and require written approval for any later configuration change.
