Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for Deere 9RX 590.
Theoretical draft formula suggests 79,650 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 (97%). Tractive efficiency is peaked within standard 8% - 12% slip window.
Tractor is currently light for this heavy draft tool. Add ~6387 kg (14,080 lbs) ballast to prevent tire slip and premature wear.
Target ballast is capped at 70,400 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.
