David Brown Implematic classic tractors for sale

History of the David Brown Implematic

David Brown launched the Implematic series in the late 1950s and early 1960s, marking a significant development in tractor design. The brand, already established in agricultural circles, built upon its earlier models by introducing advanced hydraulic systems under the 'Implematic' name. These innovations allowed implements to be controlled more efficiently, providing better depth control and maintaining consistent ploughing in variable conditions. The Implematic series became a workhorse across British and European farms, reflecting the engineering spirit of post-war Britain.

Model history of the Implematic series

The Implematic range followed on from David Brown’s popular Cropmaster line, ushering in a new era focused on operator comfort and hydraulic innovation. Within the Implematic series, models varied by power output and specific farming needs, addressing both smallholders and larger operations. They paved the way for the subsequent Selectamatic series, which would push the boundaries of precision and hydraulic advancement even further.

Highlights of the David Brown Implematic

The standout feature of the Implematic tractors was their advanced hydraulic system that set a new standard at the time of its release. The robust build quality and straightforward mechanical layout made servicing accessible for farmers and mechanics alike. Their versatility on a wide range of agricultural tasks contributed to their popularity in the UK and abroad.

Technical Data

Special Editions and Collectible Models

Within the Implematic range, various models differed mainly by engine size and optional upgrades rather than true 'special editions.' However, early production units and those with factory-fitted accessories such as enclosed cabs or industrial hydraulics are especially valued by collectors.

Weak Spots and Common Issues

Implematic tractors, while known for their robustness, can show wear in hydraulic components with age; seals and pumps may require attention. Steering boxes and brakes are areas to inspect closely, as these can suffer from wear, especially if the tractor saw heavy use. Regular lubrication and attention to the fuel system prevent many common age-related faults.

Engine and Performance, Transmission and Handling

David Brown Implematic tractors are fitted with engines optimised for torque delivery at low revs, making them effective for both tillage and transport tasks. The manual transmissions, often with a live PTO, provide dependable performance in multi-purpose roles. Operator ergonomics were a leap forward at the time, with improved seating and accessible controls.

• David Brown 850 Implematic: Popular for smaller holdings thanks to its compact size and solid power-to-weight ratio.
• David Brown 990 Implematic: Favoured for larger farms due to increased horsepower and hydraulic power.
• David Brown 880 Implematic: A versatile middleweight, well-represented in classic tractor rallies.

Interior, Comfort, Exterior and Design

Implematic tractors feature a practical, no-nonsense exterior with a focus on durability rather than aesthetic embellishment. The operator’s platform offered better comfort than earlier models, with a simplified dashboard and strategically-positioned levers. Depending on specification, some came with deluxe seats and optional weather protection. The classic David Brown livery, typically white and red, remains instantly recognisable, while steel bodywork and functional mudguards echo the agricultural ethos of the period.

Other Details

The Implematic range benefited from a wide range of period accessories – from factory-fitted loaders to power take-off options tailored for specific applications such as harvesting or baling. These features increased the tractor’s work potential and enhance their appeal for those seeking authentic period machinery.

Summary

A David Brown Implematic stands as a testament to post-war British agricultural engineering, bringing together practical design, hydraulics innovation, and day-to-day usability. Today, these tractors attract both collectors and active users, holding a unique spot in the classic tractor community thanks to their enduring build and thoughtful technical evolution.
