If you press the w button once, it will go 6.5 km/h, but if you press the w button twice, it will go 12 km/h. This also works in reverse. It is very important that after attaching the equipment, press the G button to control the animal. Its controls are like those of a car. You will find the three animals in the car category. The driver can flap with the B button. For plows, you only have to lower the plow with the V button, and that's it. The other animations are done with the B button. If you haven't read this description, it is possible that the animal will not work properly. But if you do as I wrote, it will work perfectly.
