Ford TW-30 Tractor with Air-To-Air Intercooled Engine 790888
Major design features incorporated in the new Ford TW-30 (163 HP) tractor are described. Emphasis is on the air-to-air (ATA) intercooled 401 CID (6.57 L) engine, transmission and rear axle features for the increased power, and other design changes necessary to attain the objectives set for reliability, serviceability, and performance.
Nebraska test results, which are reported in the SUMMARY, confirm achievement of the program objectives. Durability of the new tractor was evaluated by selective overload testing, using well established service and engineering test data as a base from which to judge the effectiveness of design changes.
