Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for Deere 9630.
Theoretical draft formula suggests 71,550 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.
Optimal engine load (58%). Tractive efficiency is peaked within standard 8% - 12% slip window.
Tractor is currently light for this heavy draft tool. Add ~6852 kg (15,105 lbs) ballast to prevent tire slip and premature wear.
Target ballast is capped at 65,455 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.
