[MikePhua]

Overview of the Gehl 5625SX
The Gehl 5625SX is a mid-sized skid steer loader built for versatility and durability. Powered by a Perkins 204.25 four-cylinder diesel engine, it delivers 56 horsepower and features a radial-lift boom, open-center hydraulics, and hydrostatic drive. With a rated operating capacity of 1,700 lbs and a tipping load of 3,400 lbs, it’s well-suited for construction, landscaping, and agricultural tasks.
Terminology Notes

• Radial-Lift Boom: Loader arms that arc outward before rising, offering strong digging performance and mid-lift reach.
  
• Hydrostatic Drive: A transmission system using hydraulic fluid to transfer power, allowing smooth and responsive control.
  
• Open-Center Hydraulics: A hydraulic system where fluid flows continuously through the circuit until a valve is activated.
  
• 80HE Roller Chain: Heavy-duty chain used in the drive system for durability and torque transfer.
  
• Perkins 204.25: A 2.5L diesel engine known for reliability and ease of maintenance.

Operators recommend checking chaincase oil regularly, especially after heavy use or water exposure. The planetary gearboxes should be inspected for leaks and topped off with gear oil as needed. The Perkins engine is known for its longevity, but valve adjustments and fuel filter changes are key to maintaining performance.
Field Anecdotes and Operator Wisdom

• One operator shared that his 5625SX had over 4,000 hours and still ran strong after replacing the lift chains and hydraulic hoses.
  
• A mechanic noted that the open-center hydraulic system made troubleshooting easier, especially when diagnosing slow lift or tilt functions.
  
• During a winter job in Michigan, a contractor used the machine for snow removal and praised its traction with wide flotation tires.
  
• Another user retrofitted a cab heater using a 12V marine fan and ducting, improving comfort during cold starts.
  

Historical Context and Industry Impact
The 5625SX was part of Gehl’s push into mid-range skid steers during the late 1990s and early 2000s. Its simple mechanical systems and robust frame made it popular among rental fleets and small contractors. Unlike newer models with electronic controls, the 5625SX relies on mechanical linkages and analog gauges, which many operators prefer for ease of repair.
In 2008, Gehl was acquired by Manitou Group, which continued to support legacy models like the 5625SX through parts distribution and service documentation. The machine remains a favorite among DIY owners and rural operators who value reliability over bells and whistles.
Conclusion: A Workhorse with Staying Power
The Gehl 5625SX may not have touchscreen displays or telematics, but it delivers where it counts—power, simplicity, and durability. With proper maintenance and a bit of mechanical know-how, it can serve for decades. As one veteran operator put it, “It’s not fancy, but it’s honest. And that’s what you want when the job gets muddy.”
