Single Disc Seeder Range

Versatility at it's best!

Within the Ultisow 8m to 10m range, Serafin’s have many various frame options including standard trailing models in 2 and 3 rank configurations to couple up to Tow Between or Tow Behind seeders of any brand OR you can choose from different mounted box options. 

New for 2020 is High Lift frame options with or without rolling bars are optional as well as 3m CTF frame options are available too.

But the key to all of these frame options is the fact that they are all under 3.5m transport width* so now you don’t have to compromise sowing width by having to escort the machine around farm to farm.  Now you can have the best of both worlds!

* Custom built & Hi-Lift frame machines may not be under 3.5m transport width. Please speak to your Serafin Salesman to confirm.

SERAFIN | ULTISOW S26 -S34 | SINGLE DISC SEEDER | 8 – 10m Features


Whether you are looking to sow pasture in dry conditions, canola & oats for grazing, winter cereals and beans, the Serafin Ultisow can handle it all. 

Different soil types doesn’t hold it back! Watch the video to see just how versatile it can be! 

Ease of Maintenance

Minimising down time and reduced maintenance is the key to a successful seeding operation.

The Serafin Ultisow is easy to work on and around, plus with the new SB2019 row unit the maintenance schedule is much less than many other single disc machines on the market.

Ease of adjustment

Being able to adjust your single disc row unit is critical to getting the most out of your seeder. But if it is hard to do you’re not going to do it, right?

The Serafin Ultisow is one of the simplest machines to adjust, with no tools required, This means you can quickly set it up the field so that the sowing job is spot on, every time!

Narrow transport width

Keeping the transport width down to 3.5m or less was a key factor in the design of the Ultisow S26, S30 and S34 frame design. 

Having a 8 – 10m seeder that can fold up quickly for transport and not require an escort to get around makes your farming operation more profitable and easy to manage.

Depth control & Penetration

Consistent down pressure and depth control is paramount for accurate seeding depth resulting in better germination and even strike.

The Serafin Ultisow frames are manufactured out of strong 9mm steel RHS giving it extra weight than our competitors. And by having the depth gauge wheel next to the sowing boot you can be sure of a consistent seeding depth.

Backup service and support

Apart from having a strong, reliable row unit and frame, back up and support is what keeps Serafin customers keep coming back year after year.

We have trained staff with many years experience, spare parts on hand when you need it, and fully setup service team should you require on-farm support. 

Serafin Baldan SB2019 Row Unit

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 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.

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.

We are very happy with the results. Seed placement was good, germination was good, and sowing through stubble was excellent. Our Pasture establishment was spot on too.
