Powertrain

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.

PTO Shafts

PTO Shafts

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. V Series 5000 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.


Over-running Clutch

V Series Models

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 V Series with an over-running clutch which allows the beaters to coast to a stop without undue stress.


Shafts

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.

Gearboxes

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


Bearings & Bearing Housings Bearings & Bearing Housings Bearings & Bearing Housings

Bearings

The life of a bearing is, in most cases, determined by the quality of its seals. Hagedorn uses bearings with triple-lip seals. These seals have been proven in tillage and planting equipment. Pillow block units with triple-lip seals were created especially for Hagedorn: another industry first. Our bearings are lifetime-lubricated, assuring long life and eliminating bearing maintenance. All Hagedorn bearings have an extended inner race with double set screws. Hagedorn uses premium bearings from NTN and Peer.

Bearing Housings

Ductile iron pillow blocks are the standard for Hagedorn. These virtually indestructible units are built to withstand heavy loads and impacts that would shatter ordinary grey-iron housings. For the input shaft, we demanded split housings that would allow the shaft to be removed from the machine quickly and easily without removing the bearings from the shaft. When no suitable housing was available we designed and manufactured our own so we could continue our commitment to a simple, easy to service spreader.
