A tractor with a rake to gather grass on swaths.
Motors: 1x Pf Xl
1x PF medium
To be able to make all functions motorized, I used a system of driving ring switches.
About this creation
This tractor has a 4WD, then you have to calculate the ratio's between front and back axle. I succeeded in it by having a difference of 8/100! A rake is a piece of equipment on farms, which is used to carry the mowed grass on swaths in order to gather it in harvest time. It is powered by the Power Functions XL motor and the PF medium motor.

The rake carries grass on swaths with the two rakes, driven by the PF Xl motor simultaneously.

The tractor has a quick speed, and also drives the two rakes.
