Future Work[edit]

  • Narrow down width by 4"
  • Narrow down cab to 3' as in existing LifeTrac
  • Evaluate foot pedals
  • Simplify Power Cube mounting/ Integrate into the structural frame
  • Increase height reach of Loader/ Tilt issue at full extension
  • Minimize part count
  • Design hose routing
  • Brakes
  • Cylinder valve for steering
  • Control configuration within cab
  • Utilization of all 36" of Loader Arm cylinder (or use a 4x30" cylinder if we already have adequate ROM)
  • Assess the concerns or others...
  • Fix cylider mounting -
