Poclain excavators occupy a unique place in construction machinery history. Known for their pioneering hydraulic systems and distinctive French engineering, these machines were once among the most advanced excavators in the world. Today, decades after their peak production, old Poclain models still appear on farms, small construction sites, and equipment auctions. The question many buyers face is whether purchasing an old Poclain is a practical investment or a costly mistake. This article explores the history, strengths, weaknesses, maintenance challenges, and real‑world experiences associated with aging Poclain excavators.
Poclain Company Background
Poclain was founded in France in 1927 and became one of the earliest and most influential manufacturers of hydraulic excavators. By the 1960s and 1970s, Poclain dominated the European market and exported machines worldwide. The company was known for:
Development History of Classic Poclain Excavators
Poclain’s most iconic machines were built between the 1960s and 1980s. These included models such as:
Strengths of Old Poclain Excavators
Despite their age, Poclain excavators have several notable strengths:
Exceptional hydraulic power
Poclain was a pioneer in high‑flow hydraulic systems, giving their machines impressive digging force.
Simple mechanical design
Many models used straightforward mechanical linkages and analog controls, making them easier to understand and repair.
Durable steel construction
Frames and booms were built with thick steel, allowing machines to survive decades of hard use.
Strong swing motors
Poclain’s swing systems were known for smooth rotation and high torque.
Terminology Note: Hydraulic Flow
Hydraulic flow, measured in liters per minute or gallons per minute, determines how fast hydraulic cylinders and motors operate. Higher flow generally means faster cycle times.
Weaknesses and Challenges of Buying an Old Poclain
While Poclain machines were excellent in their time, several issues make them risky purchases today.
Parts availability is extremely limited
Since production ended decades ago, many components are no longer manufactured.
Hydraulic components are expensive
Poclain pumps and motors were unique designs, making replacements costly.
Electrical systems are outdated
Old wiring harnesses often suffer from corrosion and brittle insulation.
Undercarriage wear is common
Tracks, rollers, and sprockets may be difficult to source.
Operator comfort is minimal
Cabs lack modern ergonomics, climate control, and noise insulation.
Terminology Note: Obsolete Parts
Parts that are no longer produced by the manufacturer or aftermarket suppliers, often requiring custom fabrication.
Common Mechanical Problems
Old Poclain excavators frequently exhibit:
Hydraulic pump wear
Reduced pressure and slow cycle times.
Cylinder leaks
Worn seals and pitted rods.
Swing motor issues
Internal wear causing jerky rotation.
Engine problems
Many machines used older diesel engines with limited parts support.
Structural fatigue
Cracks in booms or stick welds after decades of heavy use.
Real‑World Case Studies
Case 1: A farmer buys a Poclain 75 for land clearing
The machine cost very little upfront, but within months the hydraulic pump failed. Replacement parts were unavailable locally, and importing a rebuilt pump cost more than the machine itself. The farmer eventually scrapped the excavator.
Case 2: A contractor restores a Poclain 220 for nostalgia
A retired operator purchased a 220 because he had run one in his youth. He spent over a year sourcing parts from collectors and salvage yards. The machine now runs well, but the restoration cost exceeded the value of a modern used excavator.
Case 3: A municipality keeps an old Poclain running
A small town used a Poclain for ditch maintenance. They kept it operational by fabricating custom hydraulic lines and machining replacement bushings. The machine lasted 40 years before being retired.
Industry Context and Market Value
Old Poclain excavators typically sell for very low prices, often between:
Practical Advice for Potential Buyers
Anyone considering an old Poclain should evaluate the following:
1. Parts availability
Check whether critical components—pumps, motors, cylinders—can be sourced.
2. Machine condition
Inspect for hydraulic leaks, structural cracks, and undercarriage wear.
3. Intended use
Light farm work may be acceptable; commercial use is risky.
4. Budget for repairs
Expect repair costs to exceed the purchase price.
5. Access to skilled mechanics
Few modern technicians are familiar with Poclain systems.

Anecdotes and Historical Notes
Poclain machines were once so dominant in Europe that “Poclain” became a generic term for excavator in some regions. Operators often recall their impressive digging power and distinctive sound.
In the 1970s, Poclain excavators were used in major infrastructure projects, including highways and dams. Their legacy remains strong among enthusiasts, even though the machines are now considered obsolete for professional use.
Conclusion
Buying an old Poclain excavator can be a nostalgic and inexpensive venture, but it carries significant risks. While these machines were engineering marvels in their time, the scarcity of parts, aging hydraulic systems, and limited support make them challenging to maintain today. For collectors or hobbyists, an old Poclain may be a rewarding project. For contractors seeking reliable equipment, it is generally not a practical investment.
The Poclain legacy remains important in the history of hydraulic excavators, but modern buyers must weigh sentiment against practicality when considering these aging machines.
