The ZR-4S, the latest version of the Vermeer self-propelled baler, pushes out narrower bales than the existing ZR5-1200.
The concept of the new machine, which is listed on the Vermeer website as both the ZR-4S and ZR-2200, is largely similar to the existing model in that the Iowa-based manufacturer married one of its round balers to a front frame and suspended front axle.
The engine and hydrostat is packaged behind the Claas Jag cab, and the two front wheels continue to provide sharp turns on the headland into the next swath.
Available in North America next season, the ZR-4S/ZR-2200 uses the same Stage V 4.5-litre 200hp Cummins six-cylinder engine as the ZR5-1200 and there is no change to the two-speed hydrostatic transmission. The maximum baling speed is just short of 20km/hr, and top speed on the road is 53km/hr.
The big difference with the newcomer is in the baling department, the new model being based around the company’s Z604S bale chamber. This has a pick-up width of 1.75m (2.28m on the ZR5-1200).
The newcomer forms the same 91cm to 1.8m diameter bales as the ZR5-1200, but the width of 1.2m is narrower than the 1.55m of the ZRS-1200. Vermeer says that users have repeatedly requested this smaller size since the launch of the ZR5-1200 in 2017. Maximum bale weight is the same at 1,088kg.
