A few years ago SMS offered the seven-gang 1220P, which was similar in design to the 1520P and 1620P in that it was equipped with more hydraulic circuits, the transport wheels were located behind the rolls, and the weight of the machine was carried on the rear tractor wheels and linkage. This demanded more power and the 1220P needed a minimum of 180hp. Due to its difficulty and complexity, the production of the machine was stopped several years ago.
However, the demand for a 12m roller persisted, hence the launch of the newly-designed 1220. Joining the recently-launched five-gang 920 (9.2m) and 1020 (10.2m), the five-gang 1220 is equipped with one hydraulic circuit and the new position of the transport wheels bring the centre of gravity close to the middle of the machine. Recommended power requirement of the new trailed model has been reduced to around 130hp.
A feature of all Teran models is the patented TitanLoc ring tightening. This ensures that the rings are pressed together to reduce shaft wear. Total weight of the 1220 with standard 510/530mm rings is around 6.5t (more than 500kg/m), and 610/630mm diameter versions are available. The rings can also be swapped for smooth grassland rollers (can be ballasted) and for the first time this season cutting rollers.
Individual sections move up and down to follow ground contours and standard equipment includes 11.5-80-15.3 transport wheels and air brakes (transport width and length is 2.3m and 7.7m, respectively). The options list includes vibration absorbing rubber bearings for tough conditions and a cover crop applicator (200-500-litre hopper).
SMS has made gang rollers for nearly 30 years. It is currently seeking a number of new British partners.
