Key Features
First John Deere tractor with PTO horsepower rating; compliant with new PTO standards of 1958.
The John Deere 435, produced between 1959 and 1960, stands as a unique model in John Deere’s lineup, representing a transitional period in agricultural machinery. As the first Deere tractor to adopt the new PTO standards established in 1958 and rated horsepower via PTO after Nebraska’s abandonment of belt testing in 1959, the 435 marked an evolution in tractor design and capability. Manufactured in both Dubuque, Iowa, and Monterrey, Mexico, its production run totaled 4,626 units, making it a rare yet significant model in Deere’s history.
The 435 was powered by a robust General Motors 2-53 two-cylinder diesel engine, boasting a displacement of 1.7 liters. This supercharged diesel engine delivered 32.91 PTO horsepower and offered remarkable efficiency, achieving 2.3 gallons per hour during PTO testing. Operators benefited from a choice of 4-speed or 5-speed gear transmissions, with the 5-speed providing enhanced flexibility for a range of tasks.
Farmers found the John Deere 435 ideal for small to medium-sized agricultural operations, capable of handling 2-3 plows. The open operator station was straightforward and functional, though the option for power steering—introduced in 1960—significantly improved handling, particularly during heavy-duty applications. Its compact frame, weighing approximately 3,200 pounds, provided ease of maneuverability while maintaining a strong performance at the drawbar, tested at 27.59 horsepower.
The 435 was built for adaptability, with adjustable front and rear tread settings to accommodate various crop types and farming practices. Its open-center hydraulics system ensured compatibility with modern implements, while the optional live PTO allowed seamless operation of powered attachments.
Known for its efficiency and practicality, the John Deere 435 faced some criticisms. The 2-cylinder engine, while economical, was sometimes perceived as underpowered compared to competitors with multi-cylinder designs. Additionally, its open operator station left little protection against environmental elements, which could be a drawback for year-round operations.
The 435’s historical significance and limited production make it a sought-after model for collectors and enthusiasts. Its combination of innovative PTO design, reliability, and compact size solidified its reputation as a utility tractor ahead of its time. This model continues to represent an important chapter in the evolution of John Deere tractors, appealing to those who value performance, efficiency, and a touch of nostalgia.
