Replacement Wheel For Center Pivots
New "Mach II" replacement wheel for center pivot irrigation systems is made from an aerospace composite material that has the same tensile strength as steel yet weighs only about one third as much.
"It will outlast conventional rubber tires by years and has superior traction due to widely-spaced deep lugs that run straight across the face of the wheel as well as along both sides," says Clayton Higgins, Heartland Co-op, Trumbull, Neb. "What's more, it's resistant to chemicals so it won't deteriorate and it can't go flat like a rubber tire.
"The first time people see it they of-ten call it a plastic wheel, but it's not. The material it's made from is widely used in the aircraft and aerospace industry. Each wheel weighs about 100 lbs. less than wheels fitted with rubber tires of the same size. They'll fit any center pivot brand and can be used on any combination of towers.
"Many farmers with center pivots are switching to taller 11.2 by 38 replacement tires for improved traction. Our wheel is a couple inches taller than even those tires. A big problem with rubber tires is they have a tractor tire lug design that fills up with mud, causing the wheel to spin and get stuck. The cleats on our wheel are deep and are spaced farther apart. Also, they go straight across both sides of the wheel like the lugs found on old-time tractors with steel wheels. The result is that they're far less likely to get stuck.
"They sell for $75 to $100 more than rubber tires. To install it you simply re-move the original wheel and bolt the new one on."
