Push-Pull Plow First Of Its Kind
"You can mount one on the front, on the back or on both the front and back of your tractor," explained French manufacturer Georges Naud to passersby at the recent Royal Agricultural Exhibition who had to be convinced the revolutionary new Naud front-mounted rollover plow was not just a gimmick designed to draw them into the Renault exhibit.
"This plow makes better use of your tractor's horsepower. With the same size tractor, you can pull two more bottoms with both a front and rear-mounted plow than with a conventional rear-mounted plow alone. That saves time and fuel, reduces tire slippage almost to zero, and means less trips over fields," Naud told FARM SHOW, noting that field tests have shown at least a 10% fuel savings per acre plowed with the new push-pull plow.
The Naud plow mounts on a 3-pt. attachment bolted to the tractor's front axle and frame, where up to four bottoms can be mounted. Turnover and side movement are totally hydraulic, with depth controlled by a land wheel up front. With a few adjustments, the same plow will mount on the rear.
"With a front plow, the driver never has to look back - he simply follows his front furrow," points out Naud. "You can mount our plow on the front of your tractor and pull a different make plow behind if it's the same size plow. We can tell interested farmers whether their plow is compatible with ours."
Turnaround is also simpler, he adds. With four bottoms up front and six at the rear, he can raise both at the end of a row and turn around in half the time of a 10-bottom, semimounted plow.
"This plow is designed specifically to make better use of 4-wheel drives, replacing useless front weight ballasts with a plow that works. However, the plow can also be used with large 2-wheel-drives that are strong enough in front," says Naud.
Besides making better use of tractor horsepower, the plow lets farmers adjust to, different land conditions. On hilly ground you might use only the rear plow, for example, whereas on flat ground, you would use both. According to Naud, a 130 hp. tractor can handle an 8-bottom push-pull plow, with 3 bottoms up front and 5 in back.
To emphasize the advantages of the new plow, Naud recounted recent field tests at West Wycombe in England. In that test, two identical 118 hp. four wheel drive tractors were compared on "rock hard" sloping land, one with a reversible 5-bottom unit on the rear, and the other with a 4-bottom reversible plow behind and a 3-bottom reversible in front. Despite the two extra bottoms, the push-pull plow, because of equal weight distribution to all wheels, worked at equal or better speeds, with noticeably less slippage and better stability, according to Naud.
Eight models of the plow are available in the United Kingdom, including optional trip beam legs and various safety features. Although being distributed throughout Europe by Renault, Naud is looking for other manufacturers and distributors, and says he's already had talks with interested personnel at John Deere.
