Check out this beautiful 1973 Oshkosh P2323 snow plow recently shared by Jim.
The truck is powered by a Cummins 855 producing 250 HP which was probably considered big power back in the day. As with any good plow truck it comes equipped with full time 4×4 and a selection of gearing from the 5 speed main and 3 speed auxiliary. Both front and rear axles are rated at 23,000. This rig is tipping the scales at nearly 23k without its 12ft plow.
Depending on the version of the 855, 250 is low-end in the HP range. With the limited use plow trucks get throughout the year, that engine should last almost forever @250 hp.
This truck will be used for parades, truck shows, hauling some mulch for the house and general just driving around. It will run about 60 mph in “15” at about 2100 rpm.
