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.

Key Features:

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.

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

Gauge wheels, fitted as standard to either side, further help the pick-up to follow uneven ground contours, avoiding pick-up tine damage.

Pre-formed Slice Concept

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.

Crop Flow

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.


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.

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.

In-line Design

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.

Knotter Design

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.

System Control

A small hydraulic reservoir, pump and pressure regulator at the front of the baler, control the oil pressure in the density control rams.

Twine Storage

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.
