N.E. Hagedorn & Sons Limited



Our drivetrain is designed to be easy to maintain and service. In the 1970s, Hagedorn pioneered the use of splined shafts for high-horsepower snow blowers. Today, every shaft connection on a Hagedorn spreader is a splined connection. Splines transmit power efficiently by spreading loads to the entire shaft (unlike keyed drives that focus the load on a single stress point). Splines can be quickly and easily assembled and disassembled.

5000 Series

Every Hagedorn uses a Walterscheid PTO shaft. The heart of our PTO is its splined telescoping members. Ordinary shafts have two, three, or at best, four driving surfaces. Our splined shaft has 20 driving surfaces. Extravert 5000 Series models use a cam-style cutout clutch.

Model 8610

For 8610 we chose the smooth, quiet performance of CV joints. Like its 5000 series cousins 8610 is protected by a cam-style cutout clutch. Bring the machine to a stop. Remove the obstruction. Restart the machine. No bolts to replace. No tools required.

Heavy beaters rotating at high speed pack a lot of inertia and can cause a lot of damage if brought to a sudden stop. To protect your tractor and the drivetrain of your spreader we have equipped every Extravert with an over-running clutch which allows the beaters to coast to a stop without undue stress.

To get the power to the beaters we nestled our input shaft within the frame where it is safe from external damage. Shafts are 1045 steel, precision ground for straightness, uniformity and precise bearing fit. Our unique split housings allow the shaft to be removed from the machine without pulling the bearings from the shaft.

To meet our high standards for strength and durability in gearboxes we went to world-class manufacturer Berma for our Extravert models.
