Current U.S. LS MT774CPS cab tractor, from the MT7 brochure, the current product page and the MT774/MT7101 owner manual. 7,827 lb without ballast in the brochure and on the page (7,628 lb cabin weight in the manual).
The MT7 brochure and the current MT774CPS page list 7,275 lb hitch lift capacity (hitch end); the September 2025 owner manual lists 3,290 kgf (7,253 lbf) at the lower link end.
The 22-lb difference is under 0.5 percent. The manual’s 7,253 lb is recorded at the ends, and the screen uses the manual’s 5,181 lb at 24 inches, which no other source contradicts. No fit result changes.
