Original John Deere frontaxle 7020 LF series


Recommended Posts

I wanted my John Deere tractor to drive more realistic. I have a super smooth motor (faulhaber) and ESC (servonaut) and Digital steering servos programmed to move very slow.

But the turning radius could be better and also a real JD tilts the wheels when turning... :trucker

So here is some progress pics from the build.

Camber angle is 5 dgr. and Caster angle is 12 dgr. to give the correct steering.

New inserts for the wheels were nescessary because the turningpoint is moved further inside the rims....

The fender brackets is also redesigned. John Deere calls the mounting 'pro pivot' as the fenders is allowed to turn when they hits the tractorframe. These do the same. Two square tubes are held together with a piece of shrink tube.....

Turning radius is cut down with 15cm..... to 37cm. Very close to the original, 1:1 scale.

Thanks for watching!
