Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for AGCO Allis 9455.
Theoretical draft formula suggests 19,780 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 (297.9 HP) exceeds rated power (172 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.
Tractor is currently light for this heavy draft tool. Add ~2191 kg (4,830 lbs) ballast to prevent tire slip and premature wear.
Target ballast is capped at 18,630 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.

AGCO Allis
USA • 39 Models
AGCO Allis was a prominent name in the agricultural machinery industry, representing a significant chapter in the evolution of farm equipment manufacturing. The brand's origins trace back to the Deutz-Allis Corporation, a joint venture between Germany's Deutz-Fahr and the American Allis-Chalmers. In 1985, the North American division of Deutz-Allis was acquired by its U.S. management team, leading to the formation of AGCO (Allis-Gleaner Company) Allis. This strategic move aimed to revitalize the legacy of Allis-Chalmers, a storied American manufacturer known for its innovative agricultural machinery. Under the AGCO Allis brand, the company continued to produce a range of tractors and agricultural equipment, building on the engineering heritage of its predecessors. The brand's product line included robust and reliable tractors that were well-received by North American farmers. However, as part of AGCO's broader strategic restructuring, the AGCO Allis brand was phased out in 2001. This decision aligned with AGCO's global brand consolidation efforts, which focused on unifying its product offerings under its core brands such as Massey Ferguson, Fendt, and Valtra. Despite its relatively short lifespan, AGCO Allis played a crucial role in the transition of agricultural machinery manufacturing in North America, contributing to the industry's modernization and the development of advanced farming technologies.
