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

[meadowfield 2,864]

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!

So awesome!

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.

@meadowfield, your son is a chip off the old block, outstanding workmanship just like your "BENDY" and "C4" Wheel Horses.

Awesome!

What paint is that? It’s beautiful!

it's not 1:1 drive it's under - 20/23, axle ratios and tyre diameters are factored in and ratio is spot on. Driveshaft is splined, but actually only moves 1/8" when the axle tilts. Brake drum works as before - it's a newer version of my 4x4 wheel horse I built 12 years ago.

my 4x4 wheel horses, both use the brake drum, so that was the logical thing to do.  Front differental is a peerless built into a custom casing, Rear box is from a mower.

Exceptional work! 

 

Small block Kohler tied to a 4WD with a crawler gear? Rugged machine for certain!

Incredible work!

[AlexR 2,286]

Wow that is a lot of machine work and fabrication to do the front axle. The result is really awesome though 

[Wayne0 1,408]

That is some MAD skills!!

Absolutely amazing. I'm always in awe of any custom machine work. 

 

I'm lucky if I can drill something on center with my lathe. This is some serious fabrication skills! 

[meadowfield 2,864]

A few more - he completed the drive flanges, so now the hubs are driven.

 

 

 

 

onto final bits = the rear axle keyways were badly wallowed.

 

 

So fresh 1/4 slots milled ready for much longer keys.

Niiiiice. 

 

For that reason alone  - I would love to have a small mill. 

I'm hoping someday to figure out if I can use my recent drill press purchase.
