s650

The S650 is a standout because it represents the peak of Bobcat’s M-Series engineering, balancing size and power. Its primary advantage is the Vertical Lift Path, which allows for a higher rated operating capacity (1,220 kg) and greater reach at full lift height compared to radial lift models. For buyers, this means it is exceptionally efficient for loading high-sided trucks and stacking pallets. Furthermore, its global popularity ensures that spare parts and service manuals are readily available in almost every country, significantly reducing long-term maintenance risks for second-hand owners.

Beyond the standard engine hour check, a professional inspection should focus on three areas:

• Hydraulic System Integrity: Check the auxiliary hydraulic couplers for “sweating” or leaks and test the pump pressure under load to ensure there is no hydraulic drift.

• Pivot Points and Bushings: Inspect the loader arm pins for excessive play. A used machine with neglected lubrication will show wear here, leading to precision loss during operation.

• Drive Train and Sprockets: On wheeled units like the S650, check the chain case oil for metal shavings and inspect the axle seals. If the machine has a high-flow hydraulic option, verify that the cooling system is clean and functional, as high-flow attachments generate significant heat.

This is a vital consideration for international export. Post-2014 Bobcat S650 models typically feature Tier 4-compliant engines (like the Bobcat 2.4L or Doosan D24). These engines require Ultra-Low Sulfur Diesel (ULSD) and specialized engine oils. For buyers in regions where ULSD is not consistently available, it is crucial to discuss “Export Tuning” or ensure the machine has been fitted with high-efficiency fuel-water separators to protect the high-pressure common rail (HPCR) fuel system from contamination and sulfur-related damage.

Standard Controls: Use traditional hand levers and foot pedals. They are valued in the used market for their mechanical simplicity and lower repair costs.

• SJC (Selectable Joystick Controls): These are electric-over-hydraulic controls. SJC allows the operator to switch between “ISO” and “H” patterns. While SJC increases the machine’s resale value and operator comfort (reducing fatigue), buyers should ensure the software and wiring harnesses are in good condition, as electronic repairs can be more complex than mechanical linkages.

Yes, but it depends on the hydraulic configuration of the specific unit. A standard S650 provides approximately 87 L/min of hydraulic flow, which is sufficient for buckets, grapples, and standard augers. However, for “High-Demand” attachments like cold planers, rock wheels, or mulchers, you must look for a used unit equipped with High-Flow Hydraulics (delivering up to 115 L/min). Always verify the “High Flow” button is present on the control panel and that the additional cooling fan (located on the top of the machine) is operational before committing to a purchase for heavy-duty applications.
