Purpose-built for sowing winter cereals straight after cotton, corn, or rice.
It’s time to plant smarter with the Serafin Ultisow Row Crop 12-metre Single Disc Seeder. Purpose-built for sowing winter cereals straight after cotton, corn, or rice.
With 48 rows, 250mm spacings, a 3-point linkage swivel hitch for smooth turning, and a load-sharing rear, it’s a major leap forward from previous models.
This model is versatile with the ability to handle either larger capacity tow behind carts or the more maneuverable front mounted linkage bins.
Proving to be popular when paired up with our Ultiforce hydraulic down pressure system, this combination gives the operator the ease to transition from sowing on flat ground to raised hills and beds. No matter whether on top of the bed or down in the furrow the Ultiforce will deliver excellent seed placement and consistent down pressure.

Common options for the SM Row Unit
D-Cup Air Diffuser
Not standard but highly recommended are the D-cup plastic air diffusers which are fitted to the row unit to allow for higher rate of air flow to reduce blockages as well as reduce seed bounce.

Serafin Ultiforce is a low-maintenance hydraulic down pressure system with it’s own cylinder. It allows for more consistent down pressure, reduced row-unit vibration and increased durability, improving seed placement.

Needham Press & Gauge Wheels
New for 2021 we can offer now both the Needham V8 firming wheel and Needham Urethane Gauge wheel options for our SB2019 Disc Opener.
The V8 firming wheel is known for its longevity and ability to flex so that the press wheel continually gives the optimum seed to soil contact.
The Gauge Wheel is also very long life and quality bearing system.

Serafin Spiked Closing Wheel
Serafin’s own Spiked Closing Wheel replaces the standard smooth closing wheel. It provides some tilth next to the seed slot that assists with closing the seed slot more efficiently in harder conditions.
It also reduces the amount of closing wheel bounce resulting in more even, consistent closing wheel down pressure

Individual Small Seeds Placement kit
Allowing the operator to sow pasture seed and canola through a separate seeding tube that runs along the press wheel arm and places the seed into the seed slot once the press wheel has gone through.
This separates the main seed / fertiliser from the small seed plus sows this at a very shallow depth, independent to the main seed depth.

An upgrade option over the plastic D-cup diffusers is the Serafin Stainless steel diffuser,
Working on similar principles as the D-cup but with a longer life and stronger housing.
It also has a rubber cap that fits neatly onto the stainless steel housing, ensuring that it doesn’t vibrate off or have latches that break. And has optional shield as shown

The narrow gauge depth wheel hub on the new Serafin SM are now able to offer the BUCO narrow gauge wheel with the open 3 spoke hub.
This means that whether you are chasing the narrow spacing on the unit or just wanting to have a smaller footprint on the ground, you can still benefit from the SM open hub design.

Manutec Single Press Wheel
Replacing both the small BUCO press wheel and the cast closing wheel is the single arm with 15″ Manutec press wheel.
This works very well in soft, sandy conditions where the seed slot closes over itself. It is low maintenance and long wearing.

Manutec Mud Razor Gauge Wheel
A complete replacement of the standard BUCO depth wheel is the Manutec Mud Razoe option.
Fitted with a 4 1/2″ solid rubber wheel with an inbuilt metal scraper ring on the inside, this gauge wheel works well is muddy conditions.

Available on the Serafin SM unit is the Ryan NT (formerly RFM NT) Spring gauge wheel. Featuring improved resistance to mud build up and less weight.
The flex in the steel spring ensures that any mud build up will release, keeping the unit turning in the most sticky conditions.
