Overview of the Gehl 4615
The Gehl 4615 is a compact skid steer loader produced in the late 1980s through the early 1990s. Known for its simplicity and reliability, it was designed for light to moderate duty applications in construction, agriculture, and landscaping. While not as robust as newer models, its mechanical accessibility and affordability have kept it in use across North America.
Key Terminology
A contractor in the Midwest considered purchasing a Gehl 4615 with 3,200 hours for $6,500. After consulting with peers, they learned that similar models—like the Case 1845C or New Holland LX—offered better lift capacity and parts availability at comparable prices. Ultimately, they opted for a newer unit, but the experience highlighted the importance of market research and peer feedback.
Historical Context: Rise of Compact Loaders
In the 1980s, the demand for compact loaders surged as small contractors and farmers sought versatile machines. Gehl responded with models like the 4615, emphasizing affordability and mechanical simplicity. These machines filled a niche between wheelbarrows and full-size loaders, revolutionizing small-scale earthmoving.
Modern Case Study: Restoration in Colorado
A retired mechanic in southwest Colorado restored a non-running Gehl 4615 for use on his property. The engine was seized, but he sourced a rebuilt Perkins block from a salvage yard. After replacing hydraulic hoses, rewiring the ignition, and repainting the frame, the loader was back in service. The total cost was under $3,000, and the machine now handles snow removal and gravel grading with ease.
Tips for Prospective Owners
The Gehl 4615 remains a testament to practical engineering. While it may lack the finesse of modern loaders, its mechanical transparency and affordability make it a viable option for DIYers, small farms, and restoration enthusiasts. With proper care and a bit of ingenuity, this compact skid steer can still punch above its weight in the field.

Key Terminology
- Skid Steer Loader: A compact, engine-powered machine with lift arms used to attach a wide variety of tools.
- Perkins 108 CID Engine: A 1.7-liter diesel engine commonly found in the 4615, known for its durability and ease of maintenance.
- Auxiliary Hydraulics: Additional hydraulic circuits that allow the use of attachments like augers or trenchers.
- Lift Capacity: The maximum weight the loader arms can safely raise.
- Operating Weight: The total weight of the machine including fluids and standard attachments.
- Engine: Most units are equipped with a Perkins 108 CID diesel engine, offering modest horsepower suitable for general tasks.
- Hydraulic System: The hydraulic fluid capacity is approximately 12 gallons, supporting basic lift and tilt functions.
- Control Layout: Manual levers for drive and lift functions, with foot pedals for auxiliary operations.
- Frame and Build: Welded steel construction with a narrow stance, making it ideal for tight spaces but less stable on uneven terrain.
- Hydraulic Leaks
Aging seals and hoses are frequent culprits. Regular inspection and replacement of O-rings and fittings are essential.
- Engine Wear
With many units exceeding 3,000 hours, compression loss and injector wear are common. Rebuilding the Perkins engine is often more economical than replacement.
- Electrical Gremlins
Wiring harnesses may degrade over time, especially near the firewall and under the seat. Simple rewiring or fuse block upgrades can restore reliability.
- Control Stiffness
Linkages and bushings in the control arms may seize or wear, requiring lubrication or replacement.

Tips for Prospective Owners
- Inspect Serial Numbers
Verify the production year and engine type before purchasing. Some units may have aftermarket engines or modified hydraulics.
- Test Hydraulic Response
Slow or jerky lift arms may indicate pump wear or fluid contamination.
- Check for Frame Cracks
Look near the lift arm pivots and under the seat pan—common stress points.
- Evaluate Tire Condition
Solid rubber tires are ideal for demolition, while pneumatic tires offer better ride comfort on uneven terrain.
