A two-stage OptiFlow cleaning system with a proprietary sieve suspension and a huge area of 7.1 sq.m is used to clean the tailings. A powerful optimized air flow, a large drop height, and a finger rake on the precleaner significantly improve the cleaning performance.

The cleaning system uses an electrically controlled double-flow turbofan with the speed controlled from the cab and displayed on the control panel. Cleaning the sieves and components is easy. The sieves can be quickly adjusted by the operator from the cab.

RSM 161 is equipped with a powerful and efficient six-cylinder Cummins QSL 8.9 L6 360 hp engine. A large torque reserve (25%), a simple design, and low maintenance costs coupled with high fuel efficiency.

For the 436 h.p. combine, Cummins L9 with increased injection pressure is used.

RSM 161 combines come with a new second-generation Luxury Cab. The major difference between the new Luxury Cab and the proven Comfort Cab II is the size: the new one is more than 1,5 times bigger, with more than 4 cu.m of volume, more than 2 m wide, and a window area greater than 5 sq.m. Additional benefits include climate control, improved noise insulation and suspension for the cab, a large air-suspended operator's seat, an additional larger seat, electrically adjusted and heated rear view mirrors. The beverage cooler also has a larger capacity.
Adviser IV voice information system and Agrotronic Agromanagement platform come in basic configuration.

A new generation feeder house with an accelerating output beater features a single-point hydraulic multicoupler, adjustable for/aft tilt for higher performance and ease of work with all crops without the need to convert, with quick connection of adaptors (for the headers up to 4500 kg).

A large capacity grain tank with an advanced mechanism of unloading into vehicles with side height over 4 m, and with vibration agitators. The grain tank volume of 10,500 l allows to increase the performance efficiency by reducing unload cycles. The unload rate is 115 l/s; it takes 2 minutes to empty the full grain tank. Grain can be easily unloaded into any type of trucks or trailers, while using headers up to 12 m wide. The thresher drive can be disengaged for fuel economy.

6-step efficient walkers and an autonomous rethresher will ensure that crops are harvested with minimal loss.
A 2-speed chopper/spreader provides uniform spreading of straw across the field, operates effectively when harvesting grain and arable crops, and can be started from the cab. A large number of knives and counter knives ensures a high quality chopping. The straw spread width can be adjusted from the cab (optional).
The standard version of the combine is equipped with a chaff spreader with adjustable straw spreading width.

Depending on the version, the basic package includes an optical tailing elevator crop flow sensor (monitoring the flow through the tailings elevator). This offers a convenient way for the operator to monitor the operation of threshing and cleaning systems. The amount of incoming material is displayed in Adviser IV as absolute and relative values.
