Engine demand (83.4 HP) exceeds rated power (31 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.

Target ballast is capped at 2,533 lbs based on structural engineering estimate (~135% base weight; official manufacturer GVWR unrecorded). Avoid adding excess ballast beyond this benchmark to protect axle bearings and chassis.
