Chelsea 871 Series PTO Units
The Chelsea 871 Series is a 10-bolt PowerShift PTO for Allison 3000 and 4000 family automatic transmissions. It is a clutch type PTO with electric over hydraulic shift in 12 volt and 24 volt versions, available with or without Chelsea's Electronic Overspeed Control, and it is offered with wet spline and pressure lube options.
The 871 Series replaces the Chelsea 870 Series. If the tag on your PTO shows an 870 model number, the 871 with the same remaining model number is normally the current unit. Call us with your full model number and we will confirm it before you order. For a non-shiftable version on the same 10-bolt mounting, see the Chelsea 878 Series.
