Step 3: The chassis
Building a wooden mock up of the chassis saves a lot of mistakes and wasted metal. My best friend did the welding for me. My eyesight doesn't allow me to see well enough thru a darkened hood. He did a great job with his TIG welder. The wheel chair originally had the drive wheels in the front. Remounting them in the rear was an easy task using the same mounting points with motor pointing backwards instead of forward. The donor mower deck was then put in place to set up the overall length and position the front castors. This was also a good time to position the battery box for clearance with the deck. The final step was to fashion an electronics deck in the rear.
