Air Cart

Just simple, no-nonsense precision.
SeedMaster’s Nova Series II Air Cart offers efficient and accurate distribution. With a capacity that ranges up to 820 bushels, operators are able to stay in the field longer between fills. The Nova Series II works with the SeedMaster toolbar seamlessly, and with 10 zones of metering, it is gentle, nimble, and user friendly.

The Nova Series II is available in 520, 560, 630, 780, and 820 bushel capacities. This allows the operator to choose the right size to fit their seeding tool, their operation, and their preferred seed and fertilizer combination.

Designed for you

SeedMaster’s innovative modular design allows growers to build two-, three-, or four-tank units with 520- to 820-bushel capacity in many combinations of seed and fertilizer. From smaller toolbars right up to SeedMaster’s 100-foot toolbar, the Nova cart delivers unprecedented product distribution from tank to shank—for precise seed and fertilizer placement.

But SeedMaster doesn’t stop there. Truly innovative features like Overlap Control, load cells on Nova tanks, remote tank console, and SmartCal™ for easy product monitoring and calibration come standard, and help to make seeding faster and more efficient. Find out more.

With massive capacity, the Nova cart can meter up to 350 pounds per acre in each of the dual airstreams on a 48-foot to 100-foot air drill at 5 mph without plugging.

And the Nova 630 tow-between is loaded with all the benefits of Nova tow-behind carts to meet the unique needs of growers looking for a tow-between cart.

The remote-controlled hydraulic lids on Nova tanks increase safety and convenience during filling by eliminating the need to climb tanks to close lids. The foolproof design ensures the lids must be closed before the fans are engaged, so you can be assured that product delivery is never compromised.

Liquid or dry

Non-corrodible, rotationally moulded tanks can be set up for either liquid or dry fertilizer at the factory on the Nova tow-behind carts, each holding up to 260 bushels or 2,000 imperial gallons. An optional 40-bushel buddy tank can be added for inoculants or small seed. The optional 110-bushel tank on the Nova 630 cart is set up for dry product only.

Single or double shoot

Set up the Nova cart for single or double shoot. Or combine the Nova air cart with an UltraPro ll on-frame seed tank for even greater capacity—single shoot fertilizer from the Nova air cart and seed from the UltraPro ll tank.

Superior Distribution

Avoid downtime caused by plugging and seed crops faster with SeedMaster’s new manifold. Two types of rubber inserts are used for guiding product in the manifold head. Cone-shaped inserts optimize separation and product delivery for seed. The low seed rates provide even division and distribution. SeedMaster’s manifolds are very resistant to blockages from large-sized seeds. Improved distribution rings require no maintenance and facilitate initial product randomization.

For fertilizer distribution, the manifolds utilize flat inserts to optimize product delivery by providing excellent division at high rates of fertilizer. The inserts are easily swappable and the steel chokes require no maintenance. Manifolds are available with six, eight or 10 outlets, spanning up to 90 feet with 12-inch row spacing.

In the Zone for Increased Capacity

With up to 10 primary seed and 10 primary fertilizer runs, distribution capacity is increased by up to 50 percent. Each primary run has its own metering roller, distribution manifold, and isolated airflow for outstanding air efficiency and product flow.

Run low air speeds for canola, high speeds for fertilizer, and balance airflow across long and short runs to prevent bounce and blow out.

The 260-bushel tanks meter product from 20 pounds per acre up to more than 400 pounds per acre, depending on factors such as ground speed, product type and humidity.

Nova carts come equipped with high capacity 8-inch fans.


Wide walkways and high railings ensure operator safety.

Easy fold-up ladder

Ladders on either the UltraPro ll or Nova fold up for transport.

High capacity to carry the load

SeedMaster started with innovative design and a rugged frame designed to carry the large loads of high-capacity Nova air carts, built from the ground up.

High flotation tires were selected to reduce compaction and keep you moving on wet soils. Spend more time seeding and less time worrying about the weather.

  • Dual 710/70R38 tires on 780- and 820-bushel models (optional on 520, 560, and 630 models)
  • Single 800/65R32 tires on 520-, 560-, and 630-bushel models
Trailed Track System

SeedMaster is now offering Camso™ (formerly Camoplast®) track options for its toolbars and Nova air carts. The track option will provide farmers with greater floatation on wet soils and lower compaction.

The Camso Trailed Track System (TTS) is designed for larger footprints allowing higher weight capacity and low ground pressure performance. The tracks have low rolling and turning resistance for ease of pulling, and are the perfect choice for large fertilizer carts. The small frame TTS series is uniquely designed to provide a large footprint in a small under carriage package that fits SeedMaster Nova-ready toolbars for superior flotation compared to tires.

Camso tracks are the perfect fit for SeedMaster. Not only is it the leading manufacturer of belts and track assemblies in the world, it is the only manufacturer with sizes that work on all SeedMaster seeding systems.

More productivity with technology

Each Nova cart is loaded with technology to improve seeding efficiency and productivity.

  • Variable-rate-control ready
  • Real-Time Product Weighing™ so you know exactly how much product is in the tank
  • Overlap Control saves you money on seed and fertilizer inputs
  • SmartCal™ ready, saving seed and fertilizer by ensuring accurate product metering
  • Raven Viper 4™ in-cab monitoring

Knowing that time goes by quickly during seeding, SeedMaster designed additional options to keep you moving and to get the crop in the ground during the narrow spring-seeding window.

40-bushel tank for additional capacity

A 40-bushel rear-mount tank is available for additional product capacity. Use it for small seed, inoculants or micronutrient fertilizers, for even more flexibility and seeding efficiency. The 40-bushel tank does not have an UltraPro roller and is not available on the Nova 630 tow-between.

Truck-height loading and waist-height access to the 40-bushel tank is safe and convenient.

Load up fast

The high-capacity, user-friendly conveyor is fast at 100 bushels per minute. Fill all three 260-bushel tanks in about three minutes each, and the UltraPro ll 360 bushel on-frame tank in less than four minutes. With load cells and remote monitor, the operator is in complete control of the fill process from ground level, eliminating the need to run up and down ladders to monitor filling progress.

The conveyor comes with a kick-out bottom transfer conveyor for reaching under semis, and an extra work light at the top of the conveyor. It is hydraulically positioned and activated for fast and easy loading to keep you moving.

*All weights & widths are for standard tire option. Weights include conveyor and mount, approcimately 2,800 lbs.
