DES MOINES, la. - Making the switch from a two-wheel-drive to four-wheel-drive tractor can be quite a change. Sheer size, special convenience' and adjustment features, and articulated steering all give a 4WD tractor a different “feel” from the operator’s seat. So before you takV your first 4- wheel drive, consider these tips from Jim Lacina, Massey- Ferguson tractor specialist. (1.) Be conscious of engine warm-up. “When you first start the tractor, let it idle for two to four minutes,” Lacina suggests. “This warm-up allows bearing surfaces to become adequately lubricated and oil to fully circulate throughout engine passageways.” (2.) Learn how to handle ar ticulated steering. Lacina says this feature is standard on all MF 200- hp-and-above 4WD tractors, as well as many other 4WD units now on the market. When turning an articulated steering model, the Developing a ‘feel’ for 4WD tractors tractor bends m its middle on a pivot joint. That moves the front and rear of the tractor at the same time, occasionally creating a tendency for an attached im plement to swing while turning. “It’s really not a problem,” Lacina says. “But you should be aware of it and watch the im plement behind you until you become more familiar with the tractor and implement.” (3.) Keep an eye on gauges. “Modern 4WD tractors, are equipped with very quiet cabs,” Lacina says. “So you must closely watch gauges to monitor tractor operations.” (4.) Understand electronic draft control. This feature was recently introduced in the American marketplace as an optional feature on MF’s 4000 series 4WD tractors.' “Essentially, the draft sensing load is transmitted by electronic signals instead of mechanical linkage,” the MF expert explains.

This helps mcrease fuel efficiency.” (5.) Don’t waste the tractor’s power. “When you look at costs of running the tractor including fixed equipment cost and all operating costs - by far the largest expense is the fixed cost,”. Carina says. “Therefore, to make-best use of your investment, equip and operate the tractor to take ad vantage of its available hor sepower. Best fuel efficiency also is realized that way.” (6.) Be cautious with the turbo charger. Lacina warns that while a turbocharged engine can stand intermittent overloads to pull you through tough spots, you shouldn’t continually run any tractor in an overload condition. Overloading increases tractor wear, and can cause turbocharger damage by I 4— overspeeding. Most manufac turers install an exhaust gas pyrometer to warn when this condition approaches. Turbocharger problems can also occur if the tractor is immediately shut down in a full-load condition. When that happens, the charger will continue to run for an ad ditional minute or two.

The topics that will be discussed include: new varieties of wheat and oats, spring wheat and barley management, and seed and fungicide trials. The discussions will be lead by researchers from the center for cereals research.
