Description
Explore the suspended SmartTrax system demonstrated on a New Holland CR11 combine and described as available for CR combines. This walkaround explains how active suspension, wide 36-inch belts, four-bogie track geometry, and a large ground-contact area can improve ride quality, ground pressure, and header-height-control performance.

Common questions covered in this video:
Which combine is used for the SmartTrax demonstration? The track system is shown on a CR11 in the workshop.
Are these tracks limited to the CR11? The presenter says this track set is available on CR combines, while demonstrating it on the CR11.
What type of suspension does SmartTrax use? The presenter describes it as an active suspension system that provides a true suspension effect on the road and in the field.
How does the suspension affect the operator? It is described as producing a smooth ride and improved cab comfort across roads and fields.
How can SmartTrax support header height control? By stabilizing the combine's base unit, the suspension can reduce the motion that the header height-control system must compensate for during on-ground cutting.
Which header example is used? The presenter gives an FD2 61-foot Draper header cutting soybeans on the ground as the example.
What size are the track belts? The belts are described as 36 inches wide.
Can a wheeled combine be converted to these tracks after production? The presenter says no post-production conversion kit is available; SmartTrax must be ordered as a factory-fit option with the combine.
What does the wide beam provide? It spaces the track outward to provide clearance between the inside of the belt and the combine base unit.
How wide is the tracked combine? The presenter states an approximate overall width of 15 feet 8 inches.
How does the ground-contact area compare with 580 duals? The presenter describes it as just under three times the flat-plate or ground-contact area.
What ground pressure is stated? The video gives an approximate value of slightly more than 11 pounds per square inch.
How are the bogie wheels arranged? They are arranged in groups of four that can oscillate side-to-side and front-to-back.
Which part of the track carries most of the combine's weight? The presenter identifies the central bogie-wheel area as the primary weight-carrying section.
What is the role of the front and rear idlers? They primarily guide and support the belt and are described as not normally contacting the ground.
Does combine height change as the grain tank fills? The active suspension responds to added weight and is described as maintaining approximately the same combine height.
What grain-tank capacity is used in the example? The CR11's 567-bushel grain tank is used to compare full and empty conditions.
What road speed is stated? The presenter gives an approximate top speed of 25 mph.
What benefits does the presenter summarize? Low ground pressure, a large contact area, a smooth ride, and improved header-height-control performance.
