Now on to Forces

FUN FACT
The Chisel Plow is Considered the most important tillage tool!!!

FORCES

• Gravity
• Friction
• Thrust
• Drag
• Pressure, Momentum

GRAVITY

• Stay on the ground to dig up dirt
• Balanced
• Contact

THRUST

• Moves it go forward
• Unbalanced
• Contact

FRICTION

• In order to stop
• To go down to start digging
• Contact
• Both balanced and unbalanced

DRAG

• To stop
• Across the ground to dig up rows
• Unbalanced
• Contact

PRESSURE

• The plow pushes down to the ground
• So it can dig down deeper
• Gages
• Contact
• Unbalanced
