The last topic I published 7 months ago Lego introduced the Claas Xerion model for 2016 finally made the tread tires available. There was only one size so I decided to build a 500-600 hp articulated tractor. I have a passion for the John Deere brand so I chose the 9560R
John Deere:
The model drives the XL engine with a final gear ratio 1:6. Is fast and strong. Unfortunately I could not fit the gearbox because there was not enough space. John Deere is steering by L motor and small linear actuators. The construction has a differential locks controlled by the M motor. You can see the cutaway picture below. It shows all the mechanisms. The model is controlled by Sbrick
Vaderstad:
It's the biggest Vaderstad seeder. The real machine is working at 8 meters widths and is really big. I loaded Sbrick in the load box which controls the compressor with L Motor and two servo valves. Everything balances well even with heavy construction weight.
