- 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 -
