Muddy Mini Tractor

This is a mini 3d printed rc tractor

Supplies

You need a #1 Phillips, a small flat head, 2 16340 batteries, and a controller off this list https://github.com/ricardoquesada/bluepad32/blob/main/docs/supported_gamepads.md I will be using an Xbox One controller and that’s what the code is for but I believe any gamepad on the list will work.

Tires

Make sure the rear tires are facing opposite directions. You may have to step on these to pop the tires onto the rims.

Steering

8-8mm screws

PCB

Steering Servo

You may need to trim the edges of the hole for the servo then use the screws that came with the servo to secure it. Power up the board with the servo in the first slot and connect the controller like you would to pair it to its console. This will center the steering servo before you install the horn.

Front Axle

3-8mm screws and 1-6mm Install the servo horn in the shown position followed by the rest of the steering assembly. The 8mm screws are used to hold the axle in place and the 6mm is to connect the servo horn to the steering linkage.

Motors

Make sure the board is off then you can screw in the motors.

Rear Axle

4-10mm screws needed. I would recommend before you screw the cover down to turn on the board and make sure the motors are going in the direction you want with the controller. If they are backwards you can just swap them around.

Lift

This step has a few screws 2-6, 7-8, 2-10 and 1 long servo screw. The 6mm screws secure the trailer hook to the attachment plate then 2 of the 8mm are used to secure the servo to its mount. 3 more 8mms are used to connect the lift links to the plate. Then connect the servo to the PCB and run the lift servo as far counter-clockwise as it will go. Install horn in pictured position. The final lift link is installed using one of the screws that came with the servo in the second to last hole on the horn. The lower lift links are installed with 8mm screws and the upper and the one on the servo take the 2-10s.
