Another 4x4 - I’ll just leave this here….

My son doesn’t come on here anymore, but here is a 704 that he has been making into a 4x4. 
complete scratch built axle, and a lot of lathe and milling….

I’ll try sort some build pics out!

Some real innovative thinking there! Congrats to your son 👏
Tapping the brake drum shaft for front-drive power is so clever.

Please elaborate on the sources for the front differential and the 90º gearbox amidship!

Excellent potential there!

I see what I believe is a 1:1 chain drive to power a right-angle gearbox - also 1:1?? I ask because of the different sized tires front to rear as the circumference of both are different.

Also, is there a one-way clutch hidden in there to allow the tractor to roll in neutral with the brake applied or to semi-address my above question? I take it that the front driveshaft is splined to allow it to lengthen & shorten too, as the shaft centerline is not coincident to the front axle pivot? You got a few bucks tied up there. Off to a good start.
