Made a flapper for the exhaust today:

And mounted a horn:

 

[zetabird]

Brazed a big hydraulic fitting in the gas tank:

Brazed on some mounts:

And made a filler cap:

All together:

Mounted a couple hood fixtures:

Put on the shifter for the second gearbox:

And made a linkage for the first one:

Put on some headlights:

And a total:

Anyone able to photoshop this with some John Deere colours? Think this`d look good, but not sure about all the copper and brass...

i dont know about the deere colors, it kinda looks like a medieval helmet, i think it would look good in grays and silvers to make it look battle worn

 

[Steinbruchsoldat]

I think it`ll be a few bits of black and a lot of rust...

Located the sprocket and brake disc on the axle:

Put down a tig root pass:

And cause i don`t trust myself welding tig i ran a mig bead over it:

Sprocket is made out of some carbon steel, so i had to preheat it:

Then i faced the brake disc flange:

Put the axle together:

And put it back in:

 

[Steinbruchsoldat]

Made a mount for the brake caliper:

Put some air pressure in it to align everything:

Finished:

Then i made a battery mount:

Put in some gussets for the trailer hitch:

Preheated the drive sprocket:

Welded it to the coupling:

And put it in some blankets to cool it down nice and slow:

Then i made a fitting for the gas tank:

And brazed it in:

Mounted the kill switch:

Made the first chain guard:

And started with the second one:

Maybe i can test drive it tomorrow.

 

[Steinbruchsoldat]

Before i could continue on the chain guard i had to block the right exhaust outlet. So i turned a disc:

And welded it in:

The upper part of the chain guard:

Front side piece:

Didn`t have the right size tubing so i had to machine it:

Before welding it in i tacked in the rear side piece:

And welded everything together:

Took it apart and welded everything:

Every connection that didn`t have a lock nut got Loctite when putting it back together:

Finished the steering:

Made the brake line:

Flared it:

And bled it:

Then the only thing that was left was this mess:

So i mounted the charge controller:

The fuse box:

The ignition ecu:

So i didn`t have fuel lines, gas or the right connections for the battery. I was about to leave and call it a day when i thought it`d be a good idea to hook up the battery somehow and see if it turns, cause the battery isn`t new. So i rigged up this setup:

Turned right over:

Then i remembered that i stil have the old gas tank laying around and it should still have some gas in it. So i hooked it up and let the carburators get some fuel:

Then i pushed the start button again:

Wired in the probably most important part of the vehicle, the kill switch:

Wired the battery in:

Ran some fuel lines:

Put some gas in:

Moved it to the other part of the shop:

And hung it to the crane to test some stuff before it`s sitting on the ground. Luckily i did that, cause the clutch didn`t work. It was engaged at all times:

So i removed it and got it working...

Then i drove around quite some time in front of the shop. Unfortunately no video cause it was dark:

Appears everything is working pretty well. Need to adjust the idle and wire the fan asap. Any ideas on that? I`m thinking on just a simple switch cause there`s no water to place a temp switch.

So i brought it home today:

Here`s a really bad vid of the first tries:

Just one word: Insane

Work`s really good, has way to much power. I like it...

Here`s some test driving:

Love the video. Must have scared the neighbors to see and hear that little tiger rolling by. I think the only thing missing is a way to emit dark oily smoke form somewhere on the machine . . .

 

[Steinbruchsoldat]

So i pulled it out of winter storage today and it fired right up. This is how i like it. :grinpimp:

End of last year it started making funny noises out of the gearbox. Today it went with a bang and didn`t move at all. Well, didn`t have to look for long to see what`s wrong:

Removed the gearbox. It already had some cracks and was repaired when i got it. Thought i`d give it a try. At least it held up quite a while:

Gears and bearings look great so i just have to repair (read: make new one) this mess:

Also going to fit some new wheels up front:

Probably need to build a new front axle with some kind of suspension cause the wheels won`t compress any more...

 

[Steinbruchsoldat]

Glued the housing back together:

Made some center finders:

Roughted out the new housing:

 

[OuterLimits]

Coolest farm implement ever!!!

 

[Steinbruchsoldat]

Thanks.

First i drilled the mounting holes:

Transfer punched the centers:

Flew in the four jaw chuck:

Dialed it in:

And finished the first side:

 

[Steinbruchsoldat]

Flipped it around and turned the other side:

Fits:

I wish you were my neighbor!

I consider myself a good fabricator, and make many parts. But, you are one hell of fabricator, machinist, engineer, and all around dreamer!

Great work.
