BI-FOLD S18/S20
Single Disc Seeder
For all conditions - Particularly Large-Scale Farmers!
The Ultisow Bi Fold model is ideal for all conditions and particularly large-scale farmers. Designed for both tow between and tow behind air carts. It starts with a high quality engineered double truss frame with double folding wings that keep transport widths down to 6m for the S18 and 7m for the S20. Available in 18m or 20m sowing widths, fitted standard with the latest disc opener over two ranks with row spacing down to 187.5mm (7.5”) which makes it the perfect cereal cropping machine.
Fitted standard with the electric over hydraulic down pressure control of row units with in-cab controller and digital pressure gauge makes it extremely versatile for varying conditions. The operator can easily change the down pressure from the tractor cab depending on soil type.

SERAFIN ULTISOW S18-S20 BI-FOLD SINGLE DISC SEEDER 18m-20m Features
Super Strong Double Truss Frame
Forming the basis of the S160/S66 Ultisow is the super strong double truss frame made from massive 300x300x10mm centre chassis rails which gives it the extra strength and weight for penetration that leaves all others for dead.
The frame is finished off with full end capping and fully powdercoated to ensure your seeder lasts a lifetime.
Bi-Fold for Narrow Transport
As we all know it is getting harder to transport machines around from farm to farm. Everyone wants wider machines too.
This is were the Ultisow S60/S66 comes into its own. The clever Bi-Fold design means that it can fold up to 6m (S60) & 7m (S66) so with a double escort you can safely move the seeder.

Extra Long Drawbar & Casting Front Wheels
By having a long drawbar and casting front wheels the S60/S66 is still nimble and easily to maneuver at the end of headlines, allowing for tight turns and small head lands.
By upgrading the centre frame tyres to 400/60×22.5 as well, the tyre package is ready for narrow spacing down to 7 1/2″.

The machine has been quite reliable. We've had good service from Serafin's, and we are happy with the strength and build quality of the frame and the durability of the row units.

Serafin Ultiforce - Hydraulic Down Pressure System
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.
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
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.
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.
Other Machine Options
- Available in either 18m or 20m working width
- Available with or without rolling bar
- Can be setup for front or rear tow air carts
