Ag Tire Talk: IF/VF vs. Standard Tire Technology

Mar 07, 2024

MAXAM:“The development of IF (increased flexion) and VF (very increased flexion) technology is allowing working air pressures to be lowered significantly delivering improved performance and better crop yields.”

BKT:“There are definite advantages in using IF/VF tires and applications where they work and perform much better than standard tires.”

YOKOHAMA OFF HIGHWAY TIRES AMERICA: “That’s because IF and VF Tires can help farmers reduce compaction force on their soils by 20 to 40%, or carry higher loads than conventional radials without increasing compaction.”

MICHELIN: “Independent studies conducted by Harper Adams University and University of Illinois, Urbana-Champaign, both concluded using Michelin (IF/VF) tires, at properly recommended field air pressures, will produce up to an additional 4.31% yield.

YOKOHAMA TWS:“How can tires with IF/VF Technology carry the same load with less air pressure? The answer is because the sidewalls have been redesigned to carry some of the load, whereas standard radial tires use the air pressure to carry the entire load.”

Video: Air Command Section Control for Pro-Force Spreaders

This patented section control system uses air to divert material on to different areas of the spinner disks for precise 4-section control, for an economical design by eliminating the need for added conveyor belts or movable spreader components. The section control uses the Raven RCM ISOBUS controller and a customer’s field boundary and coverage map to automatically turn off any of the four sections at any time to avoid applying valuable fertilizer in areas where it’s not needed.

This results in fertilizer savings which means more money in your pocket for a maximum Return On Investment. The powerful blower fan sends air through a 4-section manifold while the conveyor automatically speeds up or slows down as sections are turned on or off for consistent and precise fertilizer application.

• The revolutionary patented Air Command section control utilizes a pneumatic system to accurately place fertilizer onto the spinner disks to give you individualized 4-section control of your spread pattern.

• Pinpoint accuracy of four individual sections allows you to operate the system with ease. This robust design with few moving parts offers no gimmicks, just real-world results.

• The new Air Command section control option is available on pull-type models 2250 and 1850 with the new PTO drive system, and on 1450, 1250 and 1050 pull-type models with standard single hydraulics.

• Continue to do it all with the Unverferth pull-type Pro-Force Spreader. Use the Air Command section control for spreading fertilizer and in-seeding applications, while converting to single-section lime or litter application in a matter of minute
