Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for Dongfeng DF-404.
Theoretical draft formula suggests 3,940 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 (74.9 HP) exceeds rated power (39.4 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.
Target ballast is capped at 3,884 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.

Dongfeng, also known as 'East Wind,' is a prominent Chinese agricultural machinery brand established in 1952 by Changzhou Dongfeng Agricultural Machinery. The brand's history is deeply rooted in China's industrial development, with its founding aligning closely with the country's post-war reconstruction and modernization efforts. Initially focused on basic farm equipment, Dongfeng has evolved over the decades to become a significant player in the global agricultural machinery market. The company's growth has been marked by its commitment to technological advancement and international expansion, with exports reaching various markets worldwide. While Dongfeng is often associated with automotive manufacturing due to the presence of Dongfeng Motor Corporation, a separate entity specializing in automobiles and commercial vehicles, the agricultural division has maintained its distinct identity and product line. This separation has allowed Dongfeng Agricultural Machinery to focus on developing a range of farming equipment, from basic tractors to more advanced machinery, catering to both domestic and international agricultural needs. The brand's legacy is built on its ability to adapt to changing market demands and its consistent delivery of reliable, cost-effective farming solutions.
