• 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 -
