Strip-Till

Strip-Till is the practice that promises the advantages of both, no-till and conventional farming practices. Strip-tilling fractures compacted soil. And since strip-till does not dry out soil like conventional methods of seed bed preparation, it prevents excessive moisture loss. But because farming practices vary from farm to farm between Bergville and Koppies there is not just one Strip Till machine that will satisfy everybody.

ADVANTAGES OF STRIP-TILL :

  1. The farmer is able to use a standard conventional planter. (A full No-Till planter costs more than a Strip-Till machine and a conventional planter.)
  2. Reduced tractor numbers. Fewer tractors will be needed for planting operation.
  3. Huge fuel savings. The crop is planted in only three operations. Strip-Tilling, planting and spraying.
  4. Will speed up planting operation. (The planter that follows the Strip Till machine has no residue to manage.)
  5. Straight rows due to firm ground conditions.
  6. Will be able to plant at least a day earlier after rain versus conventional tilled lands.
  7. Huge conservation advantages over conventional methods. (Strip- Tilled fields showed little or no erosion after a heavy rain storm whereas conventional methods experienced high volumes of run-off and serious gully erosion.)
  8. No compaction on lands to prevent seed emergence due to one pass seed bed preparation. (A finer conventional seed bed compacts easily after heavy rain followed by hot sunny weather.)
  9. No drying out of the top soil as soil is not turned over. One plants directly into the moist soil leaving the trash on the surface. This reduces evaporation and the drying out of the soil in the seed zone.
  10. Improves soil health in the long term as you are only disturbing 25% of the surface area.

CHALLENGES OF STRIP-TILL :

Equipment needs to be set up correctly. Not only one or two settings are necessary. Each component within each row must be adjusted, set and tensioned correctly to obtain best results. Once the complete machine is set up no further hassles will be encountered. Knee high weeds will pose a problem as the green material wraps around the residue manager’s fingers and packs on the tines.

Carrotech offers you a choice of three strip till models :

Yetter Maverick™ HR Plus RT

Carter Strip Till Machine

ALPHA II Strip Ripper

Yetter Maverick™ HR Plus RT

6-row Yetter Maverick RT Plus with dry fertiliser application

4-row Yetter Maverick RT Plus in old maize stubble

  1. Heavy-duty parallel linkage arms can be set to follow field contours.
  2. Features a 20″ cutting-coulter with 2 separate gauge wheels that are adjustable.
  3. SharkTooth® 13” Row Cleaner for managing residue.
  4. Tine with overload trip action works up to 22cm deep.
  5. Spring-loaded 16” disc sealers with down-pressure springs and infinite adjustments for width, angle, and distance from tine.
  6. Rolling basket for crumbling seed bed.

Carter Strip Till Machine

4-row Carter Strip-Till Machine

2-row Carter Strip-Till Machine

The CARTER Strip-Till unit features :

  1. Wide parallel linkage with quick-change down pressure adjustment
  2. 20″ or 22” cutting-coulter with 2 steel rims mounted onto coulter
  3. SharkTooth® 15” Row Cleaner in front or 16” concave discs behind the cutting coulter
  4. New hydraulically protected tine works up to 32cm deep
  5. Spring-loaded 18” wavy coulters with down-pressure springs and infinite adjustments for width, angle, and distance from tine
  6. Rolling basket to crumble the seed bed

Independent depth control of each Carter unit

Mounted on the cutting coulter are two depth control rims. These rims carry the whole tool carrier and ensure an even operating depth through uneven lands. The cutting depth on the coulter is not adjustable but deeper cutting can be achieved by replacing the 20 inch coulter with a 22 inch coulter

Optional positioning of the Row Cleaner :

A big advantage of the Carter is that the client has the option to have the row cleaners attached either in front or behind the cutting coulter. The row cleaners that clear a pathway through the stubble in front of the cutting coulters are 15” SharkTooth® wheels. They do a remarkable job when the stubble is too fresh or too wet for the coulter to cut and rake it aside in front. Should they be mounted behind, 16 inch conclave discs are used and working behind the cutting coulter these large diameter discs go through thick and thin opening a clear path for the following tools.

Auto-Reset Trip Tine :

There are different tines available for the Carter strip till unit that work to a depth of 32cm. All of the tines are protected by a hydraulic cylinder and a Auto-Reset trip action provides adjustable force of up to 500kg to keep the tine in the ground. Two 18″ wavy coulter break up clods and avoid air pockets in die seeding strip. They can deflect the soil to produce a ridge if desired. The Rolling basket following behind will finish off a perfect seed bed.

ALPHA II Strip Ripper

  1. A large 20 inch cutting coulter in front cuts effectively through the stubble.
  2. Two x 16 inch row cleaners mounted on large hubs with proper cub and cone bearings rake away the stubble and open up a clear path for the tine.
  3. The very strong ripper tines with a highly wear resistance tungsten face to fracture the soil up to 50cm deep.An optional beaver tail can be fitted on the backside of the shank for more soil aeration. The tines are held in the ground by a hydraulic cylinder and have a trip action when encountering stones.
  4. 18 inch wavy coulters run on either side of the tine to crumble the soil that the tine has fractured. The coulters are spring loaded and their down pressure can be adjusted. They run on an angle to form a little soil ridge behind the tine. The angle can be adjusted to determine the size of the ridge. The coulters can also be set forward or backwards to achieve a good stubble flow.
  5. A pair of paddle wheels finish off a nice prepared seed bed. The down pressure on the paddle wheels can be adjusted.

The Alpha II Strip Ripper does not consist of independent units that all carry the same tools independently, but the Alpha II is a three-beam frame construction with two large ground wheels on either side of the implement that carry the frame and all the tools without independent depth control.
