The company is excited about the launch of central-fill functionality, as it will further increase the capacity of its Tempo L range of planters. Instead of filling in each of the row units, central-fill functionality means growers will only have to fill the 3,000-litre central seed hopper. Working as a pressurized system, seed is constantly fed with high precision through Tempo seed meters. Using PowerShoot technology, seed is then “shot” into the ground.
What makes the Tempo central fill system unique is that it uses a positive air system to put the seeds in the ground, explained Clas Asknert, area sales manager for Western Canada. It delivers the seed with positive air streamed from the central fill hopper to the seed unit. From there, the positive air is used to shoot seeds into the ground.
Other planters use positive air or pressurized systems to shoot the seeds from the hopper to the small seed rows. From there, they use a vacuum system. So one part of the system pushes, while the other part sucks.
One of the benefits of using a positive air system is that it removes vibration from the equation, said Asknert.
“It’s like a pea shooter,” he said. “It’s exact.”
“For corn, this is crucial,” he added. “You get precision, even at high speed.”
Using an iPad, users enter the number of inches or even millimeters they want between each seed.
The precision placement from the PowerShoot technology remains accurate, even at speeds as high as 16 km/hr., said Asknert.
The new central-fill function will be available for Väderstad’s Tempo L planters with 12- to 24-row units, as well as for a full range of crops.
Central-fill functionality will be on the market at the start of 2021.
Väderstad’s new CrossCutter disc
Väderstad also launched its new CrossCutter disc, an ultra-shallow cultivation tool for residue management.
Creating a shallow stale seedbed not only increases the number of germinating seeds, but also reduces the amount of time needed for the seeds to emerge.
Research comparing the germination of weed seeds at six cm and four cm depths showed a 2.4-day difference in terms of germination, growth and emergence. In colder-weather regions where shorter growing seasons are the norm, gaining a few extra days is a real bonus no matter how they’re utilized.
Another bonus of the ultra-shallow disc is that it only disturbs topsoil, which helps to conserve moisture for the crop.
Asknert said the CrossCutter Disc is a good fit for Western Canada because it offers better trash management before planting or seeding.
The new CrossCutter Disc is avail- able for the disc cultivator Väderstad Carrier XL 425-625 now.
