Obmtec Morbark 1200XL Tub Grinder: mobile drum grinder on a heavy-duty chassis with a 34,250 kg gross weight, 30,250 kg unladen weight and 15,300 mm length

The Morbark 1200XL Tub Grinder is a grinding machine built onto a heavy-duty trailer chassis with a gross weight of 34,250 kg. It therefore falls into EU trailer class O4, the heavy trailers above 10 tonnes. A tub grinder shreds wood and green waste inside a round tub using a rotating hammer mill.

The chassis alone already weighs 30,250 kg, leaving only 4,000 kg of payload for the engine, tub and superstructure – a figure that shows how much weight is already tied up in the grinding unit and drive engine. At a length of 15,300 mm and a width of 2,800 mm, the machine is moved between job sites much like a heavy-duty trailer. The machine was registered in 2004.

Tub grinders of this size shred logs, stumps, branches and green waste into wood chips or mulch, and are used mainly in landscaping, land clearing and timber processing. Because of the high gross weight, the chassis runs on air brakes on all axles.

When buying used, the condition of the hammer mill and tub liner matters most, as their wear drives the running costs. Equally important are engine hours and the drive's maintenance condition, the feed hydraulics, and the chassis frame and braking system, which are heavily stressed by the machine's vibration and weight. It is also worth checking the tyres and rims of the chassis before purchase.
