The S630’s Role in Bobcat’s M-Series Evolution
The Bobcat S630 was introduced in 2010 as part of the M-Series, a generation of skid steer loaders designed to improve operator comfort, hydraulic performance, and service access. With a rated operating capacity of 2,180 pounds and a turbocharged 74.3-horsepower diesel engine, the S630 was engineered for mid-range lifting and loading tasks in construction, landscaping, agriculture, and municipal work.
Bobcat, founded in North Dakota in 1947, revolutionized compact equipment with the first skid steer in 1958. By the time the S630 entered production, Bobcat had sold over half a million loaders worldwide. The M-Series marked a shift toward pressurized cabs, improved visibility, and enhanced cooling systems, setting new standards in the compact loader market.
Core Features and Terminology
The S630 is a vertical-lift skid steer, meaning its lift arms travel in a more vertical arc compared to radial-lift designs. This geometry improves reach at full lift height, making it ideal for truck loading and pallet stacking.
Key components include:
Operators consistently praise the S630 for its smooth controls, responsive hydraulics, and cab comfort. The pressurized cab reduces dust and noise, while the side lighting and curved glass improve visibility during night work and tight maneuvers.
One contractor in Michigan used the S630 for snow removal and noted that the machine’s heated cab and high-flow hydraulics made it ideal for powering snow blowers and angle blades. Another operator in Alberta retrofitted his S630 with turf-friendly tires and used it for sod installation, appreciating the fine control and low ground pressure.
Maintenance and Reliability Considerations
The S630 was designed with serviceability in mind. Key maintenance features include:
Common Issues and Field Solutions
While generally reliable, some users have reported:
Design Evolution and Market Impact
The S630 helped solidify Bobcat’s position in the mid-frame loader segment. Its blend of power, comfort, and attachment versatility made it a strong competitor to Case, John Deere, and Kubota. Bobcat’s universal coupler compatibility allowed operators to use existing attachments, reducing fleet costs.
Sales data from 2010 to 2015 shows strong adoption in North America, with thousands of units deployed in construction, agriculture, and municipal fleets. The S630’s success led to further refinement in the S650 and S64 models, which offer increased lift capacity and enhanced electronics.
Tips for Owners and Operators
To maximize performance and longevity:
Conclusion
The 2010 Bobcat S630 is a compact powerhouse built for versatility, comfort, and reliability. Whether grading a backyard, clearing snow, or loading gravel, it delivers consistent performance with minimal fuss. With proper care and smart upgrades, the S630 continues to prove that mid-frame loaders can punch well above their weight.

Key components include:
- Bobcat 3.4L Diesel Engine: Tier 4 Interim compliant, designed for fuel efficiency and torque under load.
- Hydraulic System: Open-center design with gear pump, delivering up to 23 gallons per minute of standard flow.
- Deluxe Instrument Panel: Provides machine diagnostics, service reminders, and security features.
- Quick-Tach Coupler: Allows fast attachment changes without tools.
- Vertical Lift Path: A lift arm design that maintains bucket level during elevation, improving material retention.
- ROPS/FOPS: Roll-over and falling object protective structures, required for operator safety.
- Auxiliary Hydraulics: Additional circuit used to power attachments like augers, trenchers, and grapples.

Maintenance and Reliability Considerations
The S630 was designed with serviceability in mind. Key maintenance features include:
- Swing-out radiator and oil cooler for easy cleaning
- Centralized grease fittings for loader arms and coupler
- Color-coded fluid check points and sight gauges
- Diagnostic port for electronic troubleshooting
- Engine oil and filter: every 500 hours
- Hydraulic fluid and filter: every 1,000 hours
- Air filter: inspect every 250 hours, replace as needed
- Fuel filter: every 500 hours or annually
Common Issues and Field Solutions
While generally reliable, some users have reported:
- Intermittent joystick response due to wiring harness wear
- Hydraulic coupler leaks from O-ring degradation
- Fuel system priming difficulties after filter changes
- Cab door latch misalignment in cold weather
- Upgrading wiring harness clips to reduce vibration fatigue
- Replacing coupler seals with Viton O-rings for better heat resistance
- Using hand primer bulb after filter replacement to avoid air lock
- Adjusting latch alignment and lubricating seals during winter prep

Tips for Owners and Operators
To maximize performance and longevity:
- Warm up hydraulics before heavy use, especially in cold climates
- Keep attachment pins greased and coupler clean to prevent binding
- Use low-viscosity hydraulic fluid in winter for smoother operation
- Monitor tire pressure and wear for optimal traction and fuel efficiency
- Store indoors or under cover to protect electronics and seals
