In 2012 the Nova’s modular look and beefy design made it standout, now it gets tougher meters, poly and more wind
SeedMaster announced the first major update to its Nova air cart lineup since it was released in 2012, with the release of the Nova 2.
“The change is with all of our Nova lineup, so all of our Novas from the 520 through to the 820 are all Series 2,” said Greg Vennard, director of engineering and operations at SeedMaster.
He said SeedMaster identified that the original meter box was prematurely wearing, so the company improved its drive bushings, housing, seals, and added more bearings.
“We’ve increased the life of the meter box in the order of six times,” Vennard said.
“The idler now is engaged with the drive gears, and all of the drive gears themselves run on bearings instead of bushings, and as far as the roller goes, the roller has improved seals and bushings that it runs on.”
The air cylinder was also given improved rod seals and wipers, but users still do not need to change rollers when switching products.
The meter box update is the most significant and Vennard said it will now be able to handle five years of use without maintenance or repairs.
Some of the updates in the Series 2 can be installed on the original Nova carts.
“We have a rework program in place that can convert the original Nova to have the Series 2 meter box,” he said.
The zone controlling system that uses pneumatics has also been updated, largely to keep more moisture out of the system and extend its life.
“We’ve added drains to the tanks, so in the reservoir there is a float operated water drain in the reservoir. We’ve increased the filters, so the incoming and out coming air of the cylinder is filtered, as well as the incoming air to the compressor,” Vennard said.
SeedMaster was able to maintain a low-oil requirement and increase the air-output capacity with new S3 delivery fans.
“We’re probably the lowest in the market in terms of oil requirement, gallons per minute requirement. We’re in the 13 to 15 gallon per minute gallon range,” Vennard said.
The original Nova had hydraulically operated tank lids that helps operators open and reseal after filling, but this system has been improved in the Nova 2.
“The hydraulic lids run using the fan’s hydraulic circuits. The change is it automatically selects the fan with the highest pressure so that you’re automatically sealing your lids with the highest pressure that you have available.”
The tank lid controls enable operators to close the tank lids hydraulically when fans are engaged from the tractor cab.
There has also been improvement in axle strength and capacity, with heavier 710 tires, rims, hub studs, and wheel clamp rings.
The Nova 2 is ISO compatible so operators with a compatible tractor can use its controls to control the air cart, and the Raven Viper 4 control system that is typically delivered with the Nova 2 doesn’t need to be purchased.
The new Nova 2 comes with thicker-walled poly product tanks, improved tank scales and readout, improved conveyor, larger walkway ladder steps, and a rear-hitch option for additional ISO product carts.
The new air cart also comes with all of the features that made the original Nova popular, including overlap control, variable rate ready, 10 independent zones, dual air streams that can manage up to 350 pounds of product on a 48- to 100-foot drill at five mph, split tanks that can handle up to four products at once, isolated air streams and low air speeds for fragile seeds like canola, real-time product weighing, and calibration load cells along with the company’s SmartCal system that monitors application rates from each tank.
