🔍 Model Background

The Deutz-Fahr Agrofarm 420 (2010–2012) was designed as a flexible, mid-sized tractor for farmers and contractors seeking efficient power, straightforward operation, and cost-effective performance. Ideal for general fieldwork, transport, and livestock duties, the 420 offered a solid combination of agility and strength.

Under the hood was a 4-cylinder Deutz TCD 2012 L04 2V turbocharged diesel engine, producing up to 102 horsepower. Built to meet Tier III emissions standards, the engine delivered strong pulling power and excellent fuel economy, making it a reliable option for day-to-day farm activities.

The tractor came equipped with a fully synchronized 30x30 mechanical transmission, with optional powershift and creeper gear configurations. A hydraulic or mechanical shuttle was available, enhancing maneuverability—especially during frequent direction changes like in front loader work.

The Agrofarm 420 featured a robust open-center hydraulic system with up to 60 L/min flow and support for up to three rear remote valves. PTO options included 540, 540E, and 1000 RPM, offering versatility with modern implements.

Inside the cab, operators benefited from an ergonomic layout, panoramic visibility, and optional air-conditioning. The 420’s balanced size and comfortable operation made it especially effective in tight fields, yards, or around livestock buildings.

Built from 2010 to 2012, the Agrofarm 420 earned a reputation for being a low-maintenance, hard-working utility tractor that delivered consistent performance across a variety of farm tasks.
