Engine demand (441.5 HP) exceeds rated power (374 HP). Reduce working speed by 1.0-1.5 mph or reduce working width.

Tractor is currently light for this heavy draft tool. Add ~3841 kg (8,469 lbs) ballast to prevent tire slip and premature wear.

Target ballast is capped at 36,699 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.

Case IH is a globally renowned agricultural machinery brand with a rich heritage in tractor manufacturing. The brand's origins trace back to 1985 when the Tennaco Corporation, which had acquired J.I. Case in 1967, merged with the tractor operations of International Harvester (IH). This strategic merger led to the creation of Case IH, combining the strengths of both legacy brands. The new entity focused on leveraging the robust engineering of the IH tractor line while phasing out the larger models in favor of the more versatile Case designs. This marked a significant turning point in the agricultural machinery industry, as Case IH emerged as a powerhouse in the tractor market. In 1999, Case IH took another monumental step by merging with New Holland to form CNH Global (now known as CNH Industrial), further solidifying its position as a leader in agricultural equipment. This merger allowed for expanded research and development capabilities, leading to the introduction of innovative technologies and a broader product range. Today, Case IH continues to operate as a key brand under CNH Industrial, offering a comprehensive lineup of agricultural machinery that includes advanced tractors, combine harvesters, and precision farming solutions. The brand is celebrated for its commitment to innovation, quality, and performance, with a legacy that includes iconic models like the Steiger series, which set new standards for power and efficiency in the industry.
