The driving and steering functions are proportional, allowing for precise driving and maneuvering. The light function at the front and rear is permanently activated during operation. In standby mode, meaning after turning on the model and before connecting to the remote control module, the model indicates its readiness for operation by blinking. If the battery voltage drops below a certain level during operation, the model signals with rapid blinking that the batteries will soon be depleted. The tractor models are equipped with standard SIKU couplings at the front and rear, which are operated manually. This allows all SIKU Farmer32 trailers and attachments for the front and rear to be used with these models. The integrative play system continues with the new models. The data socket built into the rear of the tractors enables the use of control accessory models such as trailers, rakes, and plows.
