Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for Deere 9R 640.
Theoretical draft formula suggests 91,962 lbs. Official manufacturer GVWR is unrecorded for this catalog entry, so target weight is constrained to an engineering structural estimate (~135% of base operating weight) to prevent chassis overload.
Engine demand (750.6 HP) exceeds rated power (681.2 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.
Tractor is currently light for this heavy draft tool. Add ~6352 kg (14,004 lbs) ballast to prevent tire slip and premature wear.
Target ballast is capped at 60,684 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.
