New Way To Unstuck Cars, Trucks Or Tractors
Dyna-Bits strap onto the drive wheels. Each unit consists of a tire segment 3 in. wide and almost 1 in. thick with a nylon-webbed belt and buckle fastened to it. To "unstuck" a vehicle, you simply strap a Dyna-Bite to each drive wheel. The device is used in pairs - one for each driving wheel. Thus, a two-wheel drive vehicle requires one pair. Four-wheel drives take two pairs for maximum mobility.
"The key element of Dyna-Bite is the tire segment," explains Tod Granryd, inventor-manufacturer and a professional consulting engineer. "Thanks to its bite, it kicks the vehicle ahead. It also has other very useful characteristics. It's strong, conforms with the surface of the driving tire, and is capable of stretching under strain without failure. It has been tested and shown to have 3,200 lbs. of breaking strength. That's strong enough to suspend a good-sized car in mid-air with one belt, says Granryd.
"Dyna-Bites cost less than a pair of chains, yet are much more effective, and much simplier to put on and take off," Granryd points out. "Anyone who knows how to fasten and release a seat belt in a car can put the device on, or take it off, in a matter of seconds. A piece of wire comes with the product which makes for fast, easy installation. You simply thread the wire through an opening on the wheel, hook it onto a hole at the end of the belt and pull back. Next, you fasten the belt, pull it up tight and you are ready to go," explains Granryd. "The device is effective whether you drive in deep snow, mud or sand. And, it fits rear wheel drives, front wheel drives and four-wheel drives
even those with disc brakes on the driving wheels. What's more, it's equally useful whether you drive forward or want to go in reverse."
Dyna-Bites to fit most tractors will be available soon.
Looking ahead, he thinks his new Traction Intensifier will prove successful for many farm and ranch applications, including combines and other self-propelled equipment. He also thinks they will give four-wheel drive vehicles "a run for the money". Here's why:
"The premium for the increased mobility of a four-wheel,drive vehicle is about $1,200 more than a comparable two-wheel drive vehicle, plus 11 to 20% poorer gas mileage in most cases. We think we have found a way to combine the mobility of fourwheel drives with the economy of two-wheel drives -for the price of a tankfull of gas. A two-wheel drive vehicle equipped with our Traction Intensifiers can go into wet mud holes, snowbanks and up wet grass banks with the same mobility as a four-wheel drive. And, it only takes a minute or two to strap on the DynaBites to make the vehicle behave as an all-terrain vehicle," Granryd ex' plains.
The Dyna-Bite is designed so only two models - "large" and "small" - cover most cars, pickups, vans and campers. A special chart shows which size fits which tires. Generally, compact cars take the "small" size and most other vehicles the "large" size. Both sizes come in a box (7 by 7 by 31/a in.) and sell for $29 per pair, including shipping. When ordering, give tire size.
