The Bobcat S18 is a vertical‑lift model within the Earthforce series. Its rated operating capacity (ROC, per ISO standards) is 894 kg (approx. 1,971 lbs), with an operating weight of approximately 2.67 tonnes (2,673 kg). Transport dimensions are 3.33 m in length, 1.73 m in width, and 1.99 m in height.

In real‑world applications, an ROC of 894 kg means the machine can safely lift nearly 0.9 tonnes of material. The vertical‑lift path maintains good forward reach even at full lift height, with a maximum dump height of 2.23 m (approx. 7.3 ft) – sufficient for loading most standard dump trucks. For used buyers, it is essential to verify the actual ROC value on the machine’s nameplate, as variations may occur by region or bucket configuration (e.g., 858 kg with a 68‑inch Bobcat construction bucket). Always confirm against the original factory specifications.

Furthermore, under standard earthmoving conditions, the S18 can move approximately 15‑20 tonnes of material per hour, with fuel consumption around 5‑7 litres/hour – offering economical operating costs. Its vertical‑lift design keeps the bucket close to the truck bed at full height, effectively reducing material spillage and significantly improving loading efficiency. The compact 1.73‑metre width provides excellent manoeuvrability in tight spaces such as greenhouses, livestock barns, or urban streets. When purchasing used, be aware that different bucket options (e.g., light‑material or heavy‑duty buckets) affect the actual usable payload – it is advisable to consult the original technical data sheet for precise figures.

The Bobcat S18 is powered by a Kubota V2203 4‑cylinder diesel engine, with a displacement of 2.2 litres, maximum power output of 36.4 kW (approx. 48.9‑49 hp), and a peak torque of 150 Nm at 1,700 rpm. This engine complies with Tier 2 emission standards and does not require a Diesel Particulate Filter (DPF).

This configuration is a significant advantage for used buyers – it eliminates the need for DPF regeneration cycles, avoids clogging issues, and greatly simplifies maintenance, thereby reducing long‑term operating costs.

However, it is worth noting that some Bobcat S‑series models equipped with Tier 4 engines (not the early S18 variants) have been reported by users to experience computer, sensor, or emission‑related faults. In contrast, the early S18 models with the Kubota V2203 Tier 2 engine are known for superior reliability. Some owners have commented on forums that their older machines with 3,000‑5,000 hours of service are more trustworthy than newer Tier 4 units. When inspecting a used S18, pay close attention to cold‑start performance, smooth running, and check for any active fault codes.

Based on Bobcat fault code manuals and user feedback, the S18 and its siblings have several recurring issues that used buyers should focus on:

(1) Electrical and sensor faults:

• Code M0842: Battery voltage below threshold during starting – test the battery under load with a multimeter, and check terminals for corrosion or loose connections.

• Code M3721: Bucket position sensor signal lost – inspect the sensor connector and wiring harness, and replace the sensor if necessary.

• Code M1117: ECU supply voltage fluctuation – may cause false codes; measure ECU running voltage and check relays and ignition switch.

(2) Hydraulic system issues:

• Hydraulic oil leaks are among the most common problems – they can be identified by puddles under the machine or degraded performance.

• Code M0705 indicates low hydraulic system charge pressure, which may be caused by a clogged filter or a faulty charge pump.

(3) Performance‑related issues:

• A clogged air filter can significantly reduce machine performance.

• Tier 4 models may not run at full speed immediately when cold – this is part of the engine warm‑up logic and is normal.

Pre‑purchase inspection checklist: We recommend the following key checks – ① read all fault codes (focus on M0842, M3721, M1117, M0705, etc.); ② test cold and hot starts; ③ test lift and tilt functions at both idle and rated RPM; ④ inspect hydraulic hoses for leaks; ⑤ check wiring harnesses and ground points for corrosion/loose connections; ⑥ regular hydraulic oil and filter changes are essential to preventing hydraulic failures.

Based on current market data, used Bobcat S18 prices vary significantly with year, hours, and region:

• Like‑new (2025 model): one 2025 S18 C4 is listed at approximately €34,000 (approx. 34,000 euros), including a full‑glass cab and bucket.

• Mid‑age (2022‑2023 models, 500‑853 hours): a 2023 model with 500 hours is quoted at about €14,622 (approx. $17,011 USD)**; a **2022 model with 853 hours** is listed at roughly **€14,000 (approx. $16,287 USD).

• Bulk purchases: pricing for 3+ units can go as low as $16,500‑$17,000 USD per unit.

Key pricing factors:

• Hours – the most important depreciation driver. Lower hours command a premium – the price difference between a 500‑hour and an 853‑hour machine is about €1,000.

• Year – 2019 was the first production year; a 2025 model can reach €34,000.

• Configuration – features like a full‑glass cab, air conditioning, and advanced displays significantly affect the price.

• Region and exchange rates – quoted prices vary across markets, so shipping and customs costs should be considered.

The Bobcat S18 and S16 both belong to the Earthforce series and share the same platform, but they differ significantly in key parameters:

Core differences:

The S18 and S16 use a similar engine platform, but the S18 offers about 150‑207 kg (20‑30%) more ROC than the S16, while weighing only 100 kg more. This means the S18 achieves a better balance of structural optimisation and lifting capability – 20‑30% more payload from the same engine platform.

In addition, the S18’s vertical‑lift path provides better forward reach at full lift height, making it more suitable for truck loading; the S16’s radial‑lift path offers better reach within about 80% of the lift range, but its forward reach at full height is weaker.

Used‑buying recommendations by priority:

Overall, the S18 offers better cost‑performance in the used market – greater lift capacity, the advantage of vertical lift, and the strong liquidity of the Bobcat brand make it a top pick for mid‑budget buyers. We recommend focusing on 2020‑and‑newer models (with more refined specifications) and always verify hours and hydraulic system condition thoroughly.
