The Parker Chelsea 281L Series PTO is specifically designed for Allison 3000 and 4000 transmissions, providing additional clearance for mounting larger hydraulic pumps.
This model combines the proven reliability of the Chelsea 281 Series with the extended shaft design of the Chelsea 871L Series, offering greater installation flexibility without the higher torque capacity—or cost—of the heavy-duty 871L.
Production of the Chelsea 281L Series PTO began in late August 2025, with an initial lead time of approximately six weeks.
