Single Disc Seeder

Ultisow NF: The Ultimate in Versatility & Manueverabilty

The Narrow Fold (NF) Series 2 single disc seeder is the ultimate single disc seeder for those looking for versatility and maneuverability. 

Whether you are a grazier looking for a seeder with excellent penetration into hard, compacted ground. Or maybe you’re a serious cropper looking for low maintenance & reliability. Or maybe even a mixed farmer looking for something that does the lot, the  Serafin Narrow Fold has you covered.

It features a heavily constructed 12mm fully powder coated frame with drop down rear section which gives strength, weight for penetration and a lower box height making filling the boxes easier and safer. It also has the new, lower maintenance SB2019 single disc row unit with easy to adjust depth control and accurate seed placement.

All of this equals the ultimate Ultisow that is easy to transport around from job to job, no matter what it is.

Narrow Transport Width

With a narrow 3m folded width the NF is quick and easy to get around from farm to farm. 12ft gateways are no concern and there is no need for an escort either.

Being able to be configured in 5m, 6m and 7m configurations along with a range from row spacings from 157mm and up, means that no matter what the job is at hand, there is an Ultisow NF to suit.



With its 3PL hitch & its reduced frame length the Narrow Fold Series 2 is more maneuverable than ever. Tight turns at the headlands are a breeze whilst it remains stable and easy to reverse into corners.  And its easy to hook up!

Quality Strong Frame

Heavy construction 8” x 8” x 12mm RHS main frame with fully reinforced 6” x 6” x 9mm RHS wings. The frame is fully powder coated with a 3 stage process including a undercoat which adds to the robustness of the finish.  

The special Series 2 step-down section at the rear keeps the box height down, making it easier and safer for filling.

Simple Pressure Control

The Narrow Fold is fitted standard with a hydraulic valve with manual adjustment and pressure gauge to allow the operator to change the amount of pressure supplied to the row units.

This gives them the ability to setup the machine for various soil types & sowing conditions.

Backup Support

Serafin Machinery have been building No-till seeders for over 10 years and selling them Australia wide. The series 2 design came from Australian farmer feedback.

We pride ourselves on our backup aftersales support and we are willing to work with you to customize the machine so you end up with the perfect seeder for your operation.

Serafin Baldan SB2019 Row Unit

Baldan SB2019 Single Disc Row unit on stand - edit white background

Simple to adjust seeding depth with 1/2″ increments

Open gauge wheel with heavy duty hub to allow for mud / trash to escape

Large 20″ x 6mm disc blade for longer life & better penetration 

Press wheel with independent down pressure adjustment – range of tyre options

Non-greasable needle roller bearings – does away with wearing bushes & pins for less maintenance and a much longer life

Closing wheel with independent down pressure adjustment with different options of wheel type available

SB2019 Single Disc Opener

The forth generation of Serafin single disc openers from Baldan is the new SB2019 unit. This opener has many improvements over the previous models and most of these have come directly from Australian Farmer feedback.

The SB2019 has maintained its large 20″x 6mm single disc blade that operates on a 7 degree angle. It has also kept the open depth gauge wheel, the needle roller bearings in the top pivot and its simple, robust casting.

Improvements has been focused on reducing the amount of maintenance required for this unit. A single regular grease point on the auxiliary bush has a service interval of 200 hours and a bi-annual grease point on the depth adjuster handle. The new style disc hub doesn’t require greasing any longer nor does it require pre-loading. 

Other improvements have been focused on seed placement. The modified casting of the SB2019 seedboot has improved seed placement by offering a smoother flow through the seedboot. 

The row unit has also been modified to allow for a narrower spacing down to 158mm over 2 rows. This is only achievable with the BUCO narrow gauge wheel which is able to be fitted to the spoked hub since it has been reversed.

Standard SB2019 Configuration

Common options for the SB2019

Serafin Spiked Closing Wheel

Serafin’s own Spiked Closing Wheel replaces the standard closing 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 Seed Placement Kit photo
Individual Small Seeds Placement

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.

Not a standard fitment but highly recommended is an air diffuser which comes fitted to the row unit to allow for higher rate of air flow to reduce blockages as well as reduce seed bounce. 

Available in plastic D-Cup style (as per video) or a Serafin Stainless Steel type for longer service life. We also offer other diffuser options as well.

Serafin Ultisow S1260 Hi Lift Uniforce Focus 3

We can now offer the Exapta Uniforce hydraulic down pressure system to our single disc row units as a special factory order. 

This removes the standard steel spring, replacing it with a hydraulic cylinder that allows for more travel, more consistent down pressure and much smoother operation in the field.

Serafin Ultisow Hi Lift with Needham options

Available as a retrofit or factory order, we are able to offer a range of Needham aftermarket components to be fitted to our single disc units. 

These options include the popular Needham V8 firming wheel that has a long wear life & flex that allows for it to work consistently to the bottom of the furrow for excellent seed to soil contract.

Serafin single disc unit with Liquid Systems dual liquid tubes

We can offer either a complete liquid fertiliser system from Liquid Systems or just the liquid fert tubes to retrofit your own system to.

The Ultisow single disc unit can have either a single or dual tube setup mounted to the closing wheel arm. This allows the operator to direct the liquid product either in the seed trench or beside, depending on their needs.

With the outstanding success and positive customer feedback from our launch of our Ultisow S12 Hi Lift Single Disc Seeder Bar in early 2020, we had numerous calls from new and existing Narrowfold customers asking if we were going to be doing something with the NF frame to make it easier to service and adjust the units. WE LISTENED!

Introducing the new NF Hi Lift Frame option which includes a new designed rear axle and frame configuration that has two large hydraulic cylinders that allows the frame to lift up to give approx. 1,500mm underframe clearance. 

Each lift cylinder can be tapped off for added safety when working under the frame when it is in the lifted position.  Not only did we fit the lift cylinders but we also added 150mm extra frame to further increase the clearance between the front and rear rows. 

So there will be no hassle getting under and around the machine for adjusting the units, servicing the units, emptying the seed box or even fitting the calibration tray to the Gason metering system. The benefits are endless. 



Grainline Folding Loading Auger

5" Grainline Folding Loading Auger

New to the ULTISOW NF range for 2019 is the 5m x 5″ Grainline split & folding auger which is mounted to the left hand side of the Gason 1230IM box for loading both the seed and fertiliser bins. 

By having the auger split and folding, it has helped us keep the overall length down as well as give us enough length to have the auger maneuverable enough to work in almost any condition. 

A super strong mounting bracket and locking mechanism ensures that this will last the test of time.  Just ask your Serafin Salesman for a price!

Retrofittable to NarrowFold Series 2 seeders with Gason 1230IM mounted box

Maybe you are an existing NarrowFold owner and would like to upgrade your seeder by fitting this loading auger option? Sure can!

All you need to do is give us a call and we can help put together a kit for you. And if you want us to fit it too? Why not.

We could even tie it together with a pre-season service of your machine. 

All you have to do is call your Serafin Salesman for more info and pricing.
