Multi-Purpose No-Till Drill
The hottest new no-till drill in Australia is now being sold in North America by a Canadian distributor. It's designed to plant a wide variety of crops either convention-ally or no-till.
The "AgrowDrill" seedboxes mount above a 3-toolbar frame (a fourth toolbar can be added for high residue conditions). The two large seedboxes are equipped with 2 3/4-in. dia. fluted rollers that will distribute everything from light fluffy grasses to granular fertilizer in a variety of row spacings. According to the manufacturer, it works great for renovating pastures, seeding soybean/oat mixtures into alfalfa stands, establishing forage mixes in grain stubble, seeding winter wheat into corn stalks and bean stubble, spring grains into corn or bean residue, or silage corn, sorghum or beans into sod fields. Seeding rates are adjusted by shifting a lever that controls a variable speed gearbox.
"T-boot" openers mount behind self-aligning coulters. The curved design of the opener creates a suction action that pulls the boot down into the ground. Because of its suction action, the T-boot opener requires only 41/2 lbs. of down pressure to penetrate soil (compared to 125 lbs. for a conventional 12-in. dia. coulter), reducing the weight of the drill and allowing it to be used on a conventionally tilled seedbed. A high carbon spring steel triple coil tine clamps onto the frame above each opener and has 390 lbs. of breakaway force for rock protection and to maintain the opener's digging angle. The vibrating action of the coil tine also causes the opener to vibrate, allowing it to shatter compacted soil and cover the seed. Helps create a nice, loose seedbed.
The coulters are designed only to cut through surface residue and can be adjusted up or down (to expose the T-boot opener), depending on soil conditions. There's no need for extra weights which on conventional no-till drills can smear and further compact the seed zone.
A screw-adjustable hydraulic cylinder is mounted on each wheel arm to provide positive depth control. Drill's wheels can be side or rear-mounted.
Liquid fertilizer application equipment is optional.
