Step #2: Mount the Motors and Wheels PrevNext
- Wheelchair Motors — Make a simple bracket that bolts onto the existing mounts and drill two mounting holes to bolt onto the extruded aluminum. Also, install washers on the hub to space the tire away from the frame so the chains have clearance from the frame. This would be a good time to install the chains ...
- Swivel Wheels — Bolt the front swivel wheels from the wheelchair directly to the frame of the extruded aluminum.
Step #3: Install the Snowblower PrevNext
- Front — Drill through the housing on each front corner and attach bolts. Mount two brackets on each corner of the extruded aluminum. From here, drill mounting holes for the snowblower housing bolts and attach the blower with two lock nuts.
- Back — Use a simple hose clamp to anchor the handle to the frame to keep the back from kicking up when plowing the snow.
- Handle — Engage the blade by tying back the handle with a simple zip tie. If anything goes wrong, it's easy to stop the blades by sliding off the zip tie.
Step #4: BatteriesPrevNext
Mount them in the back (they help give more weight to the wheels) and wire them in series, creating 24 volts of power.
Step #5: Control SystemPrevNext
- Sabertooth 2X25 Motor Controller — Wire the receiver, batteries, and the motors to the controller per the instructions on Dimension Engineering's website. Configure the switches per their DIP Switch Wizard Tool.
- Enclosure — Mount the Motor Controller, Receiver, Power Switch, and Antenna in a neat arrangement. Attach the enclosure to the frame.
- Radio Communication — Bind the receiver to the transmitter and test the direction of rotation for each motor. Position the two antennas 90 degrees to each other.
- Accessory Functions — If you want to expand further, add a BattleSwitch! This works well on the gear channel.
