Gehl Telescopic handlers, CT/DL/RS

Additional Notes

• All six Gehl RS-series Gen:2 telescopic handler configurations listed here share an identical AdBlue (DEF) tank capacity of 19 liters, applied under normal use conditions.
• The 19-liter figure represents the total fluid capacity of the DEF reservoir, not a partial service fill, meaning the full volume is available to the exhaust aftertreatment system between refills.
• AdBlue, also known as Diesel Exhaust Fluid, is a urea-water solution injected into the exhaust stream as part of Selective Catalytic Reduction (SCR) technology, which is the aftertreatment method used across all six of these configurations.
• The Cummins QSF3.8 engine powering all listed RS Gen:2 models is a Tier 4 Final-compliant engine, a North American emissions standard that mandates SCR-based aftertreatment and therefore requires a dedicated DEF system and reservoir.
• The RS10-44 and RS10-55 Gen:2 models share a serial number entry point of S/N 90751, indicating both variants were introduced under the same production sequence despite differing in lift capacity or reach specifications.
• The RS8-42 and RS8-44 Gen:2 models also share a common serial number threshold of S/N 17801, suggesting a unified production run for both variants within the RS8 sub-family.
• Serial number thresholds vary across the RS lineup, with the RS12-42 starting at S/N 18301, the RS6-42 at S/N 15151, and the RS8 variants at S/N 17801, reflecting separate production sequences for each model line despite the uniform DEF capacity.
