- SERAFIN | ULTISOW S26 -S34 | SINGLE DISC SEEDER | 8 – 10m
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
Versatility
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
- INTRODUCING THE NEW SB2019 SINGLE DISC ROW UNIT FROM BALDAN FEATURING:
- New disc hub fitted with a single non-greasable bearing that doesn't require pre-loading
- Improved seed boot with better seed flow & placement
- New, larger fully adjustable mud scraper
- New reversed depth wheel hub that allows for baldan spoked hub on both our wide and narrow gauge buco depth wheels
- and much more.......

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
- Large 20" x 6mm single disc blade on 7 degrees
- BUCO wide rubber gauge wheel on 4 spoke hub
- BUCO "Hard Vee" rubber press wheel on solid steel rim
- BALDAN smooth cast closing wheel
- Many options available
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 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.
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.

Mounted Bin Options
Gason 1230IM or 1250IM
Optional fitment onto the Ultisow S26 – S34
The Ultisow S26 – S34 now has the option to fit up either a Gason 3,200L bin (1230IM) or the newly designed 5,100L bin (1250IM).
Both are a 2 bin design with 50/50 split, fully variable rate with electric drive, Series One metering system, and a Farmscan 7500 touch screen as standard.
Both are simple to operate, easy to calibrate and accurate. They also have a low oil requirement of approximately 75-80L/min to run.
There are many options for these air boxes including different monitor options such as ISOBUS – VT system through the Topcon Apollo, Blockage sensor kits & an additional 380L pasturebox.


Gason Mounted Bin Options
Topcon Apollo ISO kit
Topcon Apollo ISO kit that will work with any ISO terminal such as the John Deere Gen 4 terminal, ISO ready TRIMBLE screens or Topcon X35 displays. This does away with the standard Farmscan 7500 controller.
Pasture Planter
Separate 380lt Pasture Planter. This can be plumbed into the main seed tube, with Serafin’s Individual Small Seed Placement kit OR with a combination of both.
Gason Air warmer kit
Gason Air warmer kit which heats the air by taking heat from the hydraulic oil thus reducing potential for damp air causing fertilizer blockages.

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.
