Easy-to-Reach Serviceability

The G-Series features easy-to-open doors for quick access to scheduled maintenance areas, and a variable-speed hydraulic reversing fan that helps purge debris from the cooling system. Additionally, it offers excellent access to the hydraulic system on the right-hand side and complete access to the cooling system on the left-hand side for cleaning and inspection.
Undercarriage Structure

John Deere G-Series Swing Machines feature an "X" lower structure that ensures excellent load distribution and reduces stress on weld joints, while the track frames provide a smooth ride and stability across all terrains. These machines also offer tractive effort for challenging conditions, multiple track pad configurations, two-speed automatic shift travel motors, and optional tri-tracks to minimize track twisting.
