JANSEN® AT-145 ATV Flail Mower – Gas-Powered 23 PS Mulching Mower for Quads, ATVs, and Towing Vehicles

The JANSEN® AT-145 is a powerful ATV flail mower with its own 23 PS 2-cylinder gasoline engine. This allows the mulching mower to operate completely independently of the towing vehicle, making it ideal for use with quads, ATVs, lawn tractors, narrow-track tractors, or other suitable towing vehicles equipped with a ball-head hitch.

With its generous cutting width of 1400 mm and robust flail blades, the AT-145 is ideal for mulching meadows, pastures, fallow land, as well as tall grass and bushy vegetation.

Flexible applications

The JANSEN® AT-145 is ideal for mowing meadows, pastures, fallow land, as well as tall grass, brush, and straw-like cuttings. Thanks to its powerful self-propulsion system, the mower operates independently of the towing vehicle’s engine power.

The large pneumatic tires ensure a smooth ride and allow operation even on uneven terrain.

Easy operation and variable transport position

The cutting height can be conveniently adjusted using the threaded spindle located beneath the drawbar. The cutting deck can be moved into the desired working or transport position using the crank.

The wheels can be mounted either on the sides or behind the mulcher. This reduces the overall width and makes it easier to transport the machine through narrow passages.

Powerful drive and clean mulching results

The powerful 2-cylinder gasoline engine with 764 ccm and 23 PS drives the mower deck via 3 V-belts and ensures reliable power transmission.

The engine can be conveniently started using the 12-volt electric starter. Alternatively, a recoil starter is also available.

The 24 hammer blades, each weighing approximately 400 g, reliably shred the clippings and ensure a clean mulching result even with dense vegetation.

Note on the Purchase Decision

There are many competitors who lure customers with particularly low prices. It’s always best to get a personal impression of the seller and the product—ideally in person on-site or at least over the phone. We repeatedly see offers featuring photos from the Far East, which suggests that the goods aren’t even located in Europe. We also frequently hear from customers that viewings or pickups aren’t possible, cash-on-delivery payments aren’t accepted, and that a down payment may even be required before the product is available.
