Centre-Line Small Rectangular Baler
The MF 1840 small rectangular baler employs a ‘centre-line’ design in which the crop flows through the machine in a straight line – working like a mini large square baler, improving efficiency because the crop is not turned before entering the chamber.
Key features are retained from its predecessor , such as narrow transport width, 1.9m wide pick-up with standard gauge wheels, short stroke and high speed.

A real investment
The MF 1840 ‘centre-line’ baler goes from strength-to-strength thanks to its popular design and well-established reputation as the perfect small, square baler. Whether you bale a few hectares a year for your own livestock, or produce thousands of bales annually in a commercial operation, the MF 1840 will fit your requirements and budget perfectly.
The 1.9 metre wide pick-up features a small diameter, ‘low-profile’ design with closely spaced tines ensuring that windrows are picked up cleanly with minimal disturbance and leaf loss. Gauge wheels, fitted as standard to either side, further help the pick-up to follow uneven ground contours, avoiding pick-up tine damage. The MF 1840 features a four tine bar pick-up for higher throughput.
The unique centre-line construction is designed to run in-line directly behind the tractor for unrivalled convenience and field efficiency. In addition it also gives you better weight distribution and reduces ground compaction.
The crop is delivered into the pre-compression chamber where the flake is pre-formed before entering the main chamber. This ensures a well-shaped bale is formed improving bale density and reducing stress on components giving improved baler durability. With a short stroke and high speed plunger, the pre-formed slice concept enables the baler to operate with high capacity, significantly reducing plunger bearing wear whilst generating a greater number of bales.
OptiForm bale chamber
To ensure superb bale shape in all conditions and maintain consistent density, the OptiForm bale chamber is 460 mm or 30% longer when compared to the previous MF 1839 baler. To help maintain density in the toughest of conditions the bale chamber is also equipped with adjustable bale chamber resistance doors. These help to complement the pressure applied to the bale from the top and bottom density rails.

To ensure superb bale shape in all conditions and maintain consistent density, the OptiForm bale chamber is 460 mm or 30% longer when compared to the previous MF 1839 baler.
Central Knotter Greasing Kit
A new centralised greasing system is now available. Grease is fed to twelve grease points via a distribution block. There are six grease points on each knotter head. The system ensures the components are efficiently and quickly lubricated.
Gauge wheels, fitted as standard to either side, further help the pick-up to follow uneven ground contours, avoiding pick-up tine damage.

Narrow Transport Width
Even though the MF 1840 features a wide pick-up, transport width is exceptionally narrow because of the in-line design allowing easy access to narrow lanes and awkward gateways.
The unique centre-line construction is designed to run in-line directly behind the tractor for unrivalled convenience and field efficiency. It also gives you better weight distribution and reduces ground compaction.
Lower Pick-Up and Start Baling
When you get to the field, there is no need to manhandle the baler from a ‘transport’ position to a ‘work’ position – you just lower the pick-up and start baling.
Density Control Ram
The control ram applies pressure to the top and bottom density rails.
The knotters are built to operate reliably season after season, with minimum fuss or maintenance. Their rugged design guarantees excellent reliability bale after bale, whether using high quality twine.
Electric Knotter Fan
An electric knotter fan is fitted as standard to the MF 1840 and ensures the knotter are kept clean and free from any debris build up during operation.
Bale Density Control
The system automatically regulates pressure on the pressure rails of the OptiForm bale chamber to ensure consistent bale density as conditions vary across the field and throughout the day.
A small hydraulic reservoir, pump and pressure regulator at the front of the baler, control the oil pressure in the density control rams.
The MF 1840 carries 10 balls of twine which is enough for the longest days work. The large dimension of each compartment allow ‘super large’ size twine spools to be used, enabling even more twine to be carried.

Customer Reviews & Testimonials
The Broad family runs a mainly grassland enterprise over the 325 acres of slightly undulating medium loam, split between two farms around Penshurst, in Kent.
“It’s proved extremely reliable in the four years we have used it and any improvements we might have suggested have been addressed on the latest version. While other manufacturers seem to have lost interest in conventional baler development Massey Ferguson continues to improve them. That’s why we didn’t hesitate in ordering two brand new 1840 balers for our growing business.”
