Implement Draft & Ballast Matcher
Simulate draft resistance, drawbar power transfer, and optimal axle weight distribution for Ursus 1222.
Theoretical draft formula suggests 14,500 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 (166.9 HP) exceeds rated power (145 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.
Tractor is currently light for this heavy draft tool. Add ~1705 kg (3,758 lbs) ballast to prevent tire slip and premature wear.
Target ballast is capped at 14,495 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.

Ursus is a historic Polish tractor manufacturer with roots tracing back to 1893 when Zaklady Mechaniczne Ursus (Ursus Mechanical Works) was established in Warsaw. The company initially focused on agricultural machinery and tools before achieving a significant milestone in 1922 with the production of its first tractor. This marked the beginning of Ursus's journey as a major player in the agricultural equipment sector. The 1950s were a period of growth and technological advancement for Ursus, as the company began manufacturing tractors based on Zetor designs, which proved to be highly successful and solidified its reputation in the Eastern European market. In the 1970s, Ursus further expanded its technological capabilities through a licensing agreement with Massey Ferguson, a leading global tractor manufacturer. This collaboration allowed Ursus to incorporate advanced design and engineering principles into its products, enhancing their performance and reliability.
