Tractor (chaneling 8859 Tractor)
Only 3 rubber bands were added to make this alternate model.
Ford/New Holland Tractor with Rotary and Sickle Mower implements.
Functions include: Steering, PTO and 3-point hitch raised with pneumatics. Along with two implements that run off tractor's PTO.
In the raised position the mower disconnects from the PTO, stopping the blades.

Switching Implements
The small gear must be switched to the new implement and the pneumatic hose connected.
Sickle mower attached
Flipping a pneumatic valve on the mower lowers the mowing arm.
From the PTO, a rubber band drives the reciprocating sickle blades while moving, if the mower is in the lowered position.

Adding two more wheels to the set allows for a more tractor-like appearance,
Below are links to videos showing the mowers working.

Internal mechanism
Geometry of the mechanism
Close up of main rotor and tail rotor connection.
Note the angle of the small gear allows it to miss the side gear while still engaging the top gear.
Delorean Jet powered Time Machine
Pneumatic Door openers, Spinning front jet, Steering in cockpit and hand of God.
Because of the wider steering, the rack is higher than normal so it wouldn't work with a horizontal shaft.
I had to angle the steering shaft so the pinion gear worked on the rack
Drivetrain. The front Jet was geared up so it spins slightly faster than the wheels.
