bobcat

The Bobcat S650 is a vertical‑lift machine in the 600‑frame size class. Its rated operating capacity (ROC) per ISO standards is 2,690 lbs (1,220 kg), with a tipping load of 5,380 lbs (2,440 kg). The machine’s operating weight is approximately 8,061 lbs (3,657 kg).

In practical applications, an ROC of 2,690 lbs means the loader can safely lift over 1.2 metric tons of material – roughly equivalent to moving 1.1 cubic yards (0.91 m³) of standard‑density material in a single bucket pass. The vertical‑lift path provides excellent reach at full height (forward reach of 31.5 inches at maximum lift), making it ideal for truck loading. The dump height reaches about 8 feet (2.45 m).

For used buyers, it is critical to verify the actual ROC number on the machine’s factory nameplate – some markets (e.g., Europe) list slightly different values (1,227‑1,282 kg) depending on the year and configuration. Always confirm the original specification before purchase.

The Bobcat S650 is powered by a 74‑hp (55.2 kW) turbocharged diesel engine. Its most distinctive feature is the Ultra‑Low Particulate Combustion (ULPC) technology, which uses a specially designed combustion chamber to significantly reduce soot formation – eliminating the need for a Diesel Particulate Filter (DPF) while still meeting Tier 4 emission standards.

For used buyers, this is a major advantage – no DPF regeneration cycles, no DPF clogging issues, and reduced downtime. Bobcat also extended maintenance intervals: engine oil and filter changes are now recommended every 500 hours (up from 250 hours), lowering long‑term operating costs.

However, real‑world user feedback points to some concerns with this Tier 4 engine:

• Some users report power derating in cold weather conditions.

• The engine is sensitive to fuel quality – “doesn’t like dirty fuel” is a common comment.

• A few owners have experienced start‑and‑stall issues, often traced to the fuel shut‑off solenoid or its wiring.

When inspecting a used S650, pay close attention to cold‑start performance, smooth running under load, and verify that the fuel system maintenance records are complete.

Based on extensive owner reports and forum discussions, several recurring issues are well documented. Used buyers should focus on these areas:

1) Hydraulic system faults

• Code M0721 – “Hydraulic oil temperature out of range (high).” This can persist even after replacing the temperature sensor, fluid, and filter.

• Weak lift at idle – the machine lifts properly only at higher RPM, a frequent complaint.

• Hydraulic hoses, especially the pressure line from the pump to the control valve, are prone to wear or rupture with age.

2) Fuel and electrical system faults

• Code P0254 – Fuel pressure regulator control circuit fault. This often involves a faulty fuel pressure sensor and injector control valve. Even after replacing the suction pipe, fuel filter, IMV, and injectors, the root cause may be a damaged/corroded wiring harness or connectors.

• Code M0921 – “Fuel level out of range (high).”

• A classic fault on 2012 models is engine starts then shuts down – typically linked to the fuel shut‑off solenoid or its electrical connections.

3) Lift/tilt response issues

• Slow lift and tilt under load, with engine RPM increasing but no hydraulic response – usually points to hydraulic pump or valve problems.

Pre‑purchase inspection checklist:

• Read all fault codes (focus on M0721, M0921, P0254, M1832, etc.).

• Test cold and hot starts – confirm the fuel shut‑off solenoid operates correctly.

• Test lift and tilt functions at both idle and rated RPM.

• Inspect hydraulic hoses (especially from pump to valve) for wear or leaks.

• Check wiring harnesses and ground points for corrosion or loose connections.

Based on current market data, used Bobcat S650 prices vary significantly with age, hours, and options:

• Like‑new (2023‑2024 models, under 50 hours): approximately $52,500 – $56,000 USD. These often include remaining factory warranty and high‑end options (Selectable Joystick Control, comfort package, two‑speed, Power Bob‑Tach, etc.).

• Mid‑age (2019‑2020 models, 2,000‑3,500 hours): broad range – a 2019 model with 3,451 hours may list around $21,900**, while a **2016 model with 3,741 hours** could be priced at **$28,900.

• Newer low‑hour units (2020 model, 0‑2,000 hours): some listings reach $61,400.

Key pricing factors:

• Hours – the most important depreciation driver. The S650’s design life is roughly 8,000‑10,000 hours; lower hours command a premium.

• Year and emission standard – the S650 was first produced in 2017; 2019+ models feature refined specifications. All 2017+ units use the Tier 4 ULPC non‑DPF engine.

• Options – two‑speed travel (standard 7.1 mph / high 12.3 mph), high‑flow hydraulics (standard 23 gpm / high‑flow 30.5 gpm), Selectable Joystick Control (SJC), Power Bob‑Tach, etc., all affect resale value.

• Attachments and service records – included buckets and documented maintenance history add value.

(1) Bobcat S650 vs. Caterpillar 262D

Both have nearly identical horsepower (74.3 HP) and ROC (S650: 2,690 lbs; CAT 262D: 2,700 lbs). Key differences:

• Lift path – both are vertical‑lift, but the S650’s dump height (8 ft) is slightly higher than the CAT’s 7.9 ft.

• Maintenance cost – the S650’s DPF‑free engine simplifies aftertreatment, lowering long‑term costs; the CAT 262D has more complex electronics and sensors, which some owners find more expensive to maintain.

• Price – the S650 generally offers better upfront value in the used market.

(2) Bobcat S650 vs. Kubota SSV75

Horsepower and lift capacity are similar. The S650 advantages include higher tipping load and faster travel speed. The Kubota SSV75 has a slightly lower operating weight, which may be beneficial for certain applications.

Used‑buying recommendations by priority:

Overall, the Bobcat S650 stands out in the used market for its cost‑performance ratio – vertical lift capability, low‑maintenance non‑DPF engine, and the mature Bobcat attachment system make it a top pick for mid‑budget buyers. When shopping, prioritise 2019‑and‑newer models (more refined specs) and always verify hours and hydraulic system condition thoroughly.
