Introduction - 7420, 8420 & 8420G Snowblower
Introduction
Allied has years of snowblower manufacturing expertise and thousands of acreages, farms and
cities depend on Allied snowblowers.
PTO-driven Allied snowblowers attach to a tractor’s 3-point hitch. This snowblower is supplied with
Category 2 pins with conversion bushings to Category 3 available. The 7420 and 8420 snowblowers
have open gearboxes. The Y8420G has an oil bath gearbox. Adjustable cup type skid shoes are
standard on all models.
Shear bolt protection is provided at the sprocket to the main auger, and is easily accessed by
removing nuts and cover at the back of the housing.
A hitch system, which is quick-hitch compatible is standard on all models. A longer 36" PTO shaft is
optional.
Also available is an optional Hydraulic Spout Control. There is a shear bolt on the auger and on the
PTO shaft to protect the machine from damage if a large object is picked up. Any smaller objects
in the snow will be thrown with it and could cause serious injury. Do not allow anyone to stand
behind the tractor or in the area of the discharged snow.
