APPENDIX B: CUTTING EDGE INSTALLATION
ON THE 5-TON TRUCK SNOWPLOW
Installing the carbide blades and the steel blade together on the R3611M
"Wausau" brand Schmidt Engineering and Equipment, Inc. snowplow requires
the following steps:
1. Raise the blade mounted on the truck, and place heavy timbers just under
the plow frame immediately behind the plow moldboard. Allow enough room to
reach the nuts along the bottom edge and to use an impact wrench. Leave the
blade attached to the truck.
2. Be sure the brakes on the truck are set and shut down the engine.
3. Remove the old cutting edge by removing all the bolts along the bottom.
Unless some have been lost, there normally are 13 bolts to remove. Clean the
area along the bottom of all rust and dirt; a wire brush works well. If you have
time, spray all rust areas with rust inhibitor paint.
4. To install the new combination cutting edges, put one of the 4-foot
pieces of carbide steel cutting edge on one end. Hold in place by using two
recessed-head short bolts installed as indicated by the small arrows. Tighten the
nuts loosely to hold the 4-foot piece in place.
5. Then install the other 4-foot piece on the other end. Hold it in place by
two recessed-head short bolts and tighten only loosely. Then install the 3-foot
piece in the middle, hold in place with one recessed-head short bolt, and tighten
6. Finally, install the 11-foot steel blade; put a non-recessed-head long bolt
at each end and tighten only loosely; then install the other six long bolts and
tighten loosely. Then, using an impact wrench and beginning in the middle,
tighten each bolt alternately until all are secure.
7. CAUTION: Blades are heavy and if dropped can cause severe injury to
hands and feet. Use two persons at all times and work slowly and carefully. Be
sure no one climbs into the truck while this work is being done.
