JANSEN® AGF-140 Slope Mower – rugged slope mower with a 138 cm cutting width

The JANSEN® AGF-140 is a particularly robust slope mower designed for demanding mowing tasks on slopes, ditches, riverbanks, earthen embankments, field edges, and hard-to-reach areas.

Compared to lighter models such as the AGL-140 or AGL-145, the AGF-140 is the heavy-duty version in this mower class. Thicker materials, heavy hammer blades, and a specially reinforced bevel gear ensure high stability, a long service life, and powerful mulching performance.

Heavy-duty construction for high loads

The AGF-140 was developed for intensive use. The widened mulching housing, the heavily reinforced three-point hitch, the reinforced trailing roller, and the reinforced flail shaft ensure a particularly stable overall construction.

Weighing approximately 730 kg, this slope mower is among the heaviest machines in its class, offering smooth operation and high durability for demanding tasks.

Versatile thanks to lateral offset and tilt

Thanks to its lateral offset, the JANSEN® AGF-140 is ideal for mowing ditches, slopes, riverbanks, earthen embankments, and hard-to-reach edge areas.

The mower unit can be moved to the left and right and hydraulically angled. The tilt range is +90° upward and -55° downward. This requires 2 hydraulic control circuits on the tractor, as the machine is equipped with 2 double-acting hydraulic cylinders.

At maximum lateral extension, the distance between the center of the tractor and the outer edge of the mulcher is approximately 233 cm.

Includes ball valve for float position

Includes ball valve: The JANSEN® AGF-140 comes equipped with a practical ball valve solution for activating the float position on the hydraulic cylinder.

The robust shut-off valve allows for easy switching between the transport position and the float position. This enables the mower to adapt more flexibly to the terrain when needed and to better follow uneven ground, slopes, or road shoulders.

Simple, robust, and low-maintenance

• Mechanical solution without a power connection
• Quick switching to float mode via ball valve
• Optimal ground adaptation on uneven terrain
• Compatible with JANSEN® AGF slope mowers
• Low-maintenance, durable, and ready for immediate use
• No additional hydraulic circuit required

The ball valve solution is a simple and reliable way to utilize the float position on the hydraulic cylinder and improve work quality on uneven surfaces.

12 heavy hammer blades for a clean mulching result

The 12 specially hardened hammer blades, each weighing approximately 1.2 kg, reliably shred grass, tall cuttings, straw-like material, and bushy vegetation down to a minimum.

In addition, the AGF-140 is equipped with 2 counter blades. This shreds the material even more thoroughly and achieves a clean mulching result.

Double-spiral rotor for smooth operation

The built-in double-spiral rotor distributes the load evenly across the rotor shaft. As a result, the mulcher runs more smoothly, works more efficiently, and requires less effort.

At the same time, vibrations are reduced and the service life of the drive components is extended.

Safety and Well-Designed Features

The JANSEN® AGF-140 features improved collision protection. Upon contact with obstacles such as fence posts or rocks, the slope mower can swing upward to reduce the risk of major damage.

A very heavy trailing roller ensures even ground contact. The free-wheel transmission protects the drive, while pendulum-suspended, galvanized slats at the front reduce the ejection of stones and clippings.

Sturdy transport rollers facilitate maneuvering on level, firm ground without being attached to the tractor.
