John Deere 9650 STS Combine
Problem Statement:
Design a fan similar to a leaf blower that will keep debris from building up on top of the feederhouse of a combine. It should engage with the header control and be able to withstand the environment it will be in.
Objectives:•Design the apparatus necessary for a mechanically
driven squirrel cage fan.•Design the apparatus necessary for an electrically-
powered squirrel cage or centrifugal fan.•Design the apparatus necessary for a hydraulically-
driven centrifugal cage fan.•Construct and evaluate the design approved by the
sponsor, Mike Chapman of Chapman Farms Inc.

Chosen Design
Electric DriveElectric Drive
Simple construction and low cost.
Materials used were appropriate because the return value to the sponsor would not justify an expensive solution.Design can be used on multiple makes and models of combines.
Electric Schematic
The motor is turned on when the header is engaged by means of a relay.
10 gauge wire is needed to supply the 22 amp load to
and from the motor relay.A 30 amp inline fuse is used
between the battery and the relay.
