From YouTube: Tractor Measurements -

Description

Includes foot pedals.

A

Okay, here's a few more measurements on life track, 5, okay, start with a trip pedals here in the cab, so cabs got to control joystick and some foot pedals six of measurements. So this piece here the foot pedal itself, that's 8 inches by four. The height of this one here is about four inches. For this piece sticking out. The height of that poem is about one and three-quarter inches the length of these pieces.

A

They look like a 1 by a quarter by one now the different distance there is about 14 inches of 14 inches in one of them.

A

Each one of them is this. This one here is 14 inches right. There.

A

The second one that goes actually into the valve is about 10 inches.

A

Yep and the bolts they have a slot so that these things are adjustable. They're half inch bolts, the shaft here with here that'll, be 16. Inches chef itself is 17 inches. There's 21 inch nuts, underneath the pedal there's some grooves set up in place mounting plate here, eight inches by 8, inches or bolts. On top of that, okay, some other measurements. Let's say to this one part right here: loader attachment, so the existing lower arms are.

A

48 inches this here, this HP 16 inch piece here on the back. These two are holding like this there's an eight by eight inch piece here. This piece here is cut out so that the whole dump can happen. This piece here is three holes: 12 inches this one's 16 inches it's another plate here, 8 by 16, have these two tubes for the loader total distance of twelve inches. Here we've got this.

A

Basically, the this one ring here and the bottom ring are not funded. The part. That's threaded is, if you spin this, the nuts there are threaded, so you can actually lift lift this pin out and there's a small tube that looks like a three-quarter inch pen.

A

You could either lift and manually by hand and goes out a lot in the in the bucket itself. So that's that's proper mm-hmm, so the bucket quick batch is just like it up and the CAD drawings. So here's some of the bolt patterns, long bolt, 8 inch here short bolts here, just Stubbs- is one all the way through down there all the way through here all the way through from this one. This one is here, goes clear through the 12 inches this one here this one here goes: let's see, what's.

A

So this is pen around which the.

A

So this part moves here this. This is what rotates here around this pin here to be type here.

A

What else? So this is stiff, stiff, mount here, stiff mounted here. This is the pin around which the the quick attach would rotate these. So these two pieces are bolted together through this bolt, which goes all the way through to the other side and.

A

This both here all these bolts they just hold on the plate onto the quick, attach just going through the detail, the bolts, so this one goes you're here, the one third one this one here that goes all the way through, so that's a 12 inch bolt 12 inch or longer this one goes all the way through now, there's nothing I, don't see anything there. This is just a holding this piece here.

A

Let's see, come the other side.

A

So this piece here these two pieces that the poor boy, poor tubes, are held by this bolt right there in between so there's a lot of complex bolting here this one here from this side, that's the one that goes all the way through this one goes through to hear.

A

That's about Batman here as far as the corner joint we've got just a 90, simple, 90 degree angle, 8 by 16, plate here and then 8 by 16, going down, and this for by 12 is what the cylinder is attached to right here.

A

Now, here's our screen, here's the turn on switch.

A

This is the one we're using right now to actually extend like it. We can do it by hand. We use this a handle here, so you can spin this readily to take out the pin on the quick attach.

A

A

Seeing the way it works.

A

I'm not sure how this is working here. This doesn't appear, obviously, when I'm spinning this all that happens is that this this pin goes up here. This goes up, but this thing is not not moving, so there needs to be another holder on this mechanism. This mechanism is not correct right. There.

A

So some more details.

A

Mounting these bolts and could be trimmed down here, a lot of sharp edges. Let's get rid of these sharp edges, just like they're, so the big cylinder here, the we're finding out the dismount here that have to be welded on, because that wasn't strong enough to hold them. So this is all welded here that wasn't strong enough to hold this. This cylinder basically made this thing bend out through these bolts mm-hmm. Now this big pivot. Here, that's working. We've got colors here as far as the pivot.

A

Here, this is working well with a big pin mounting here mounting to the back through eight inches of mount on the pivots. Let's see the look of the other side.

A

As far as a cylinder that looks like that all works, this mount here to the back part mount to the front part, that's how it looks.

A

And the back I'm doing all these pieces is the adjust from before hold the other power cube back in, and this is the new power cube. That's up so this appears to be a 36 horsepower diesel engine there's a radiator tanks are vertical in this case. So that's the fuel diesel and this is the hydraulic tank which is filled. It's got a side gauge on the side, nice big fittings.

A

And further details here this these details here, that's a little improvements can be made just to streamline this whole thing.

A

A

And yeah like simplifications here like the way we were mounting this here yesterday, a double attachment to these plates, but we might want to revisit that see how differently we can do this, so you can get rid of all these extra pieces here. They're not necessary, like, for example, this one. This piece here will probably combine be combined with this piece here. Somehow well, there's a cylinder mounting back there, but we'll see how we can streamline all of this to make it even simpler. What I'm?

A

Looking at this, my first instinct says: there's too many parts here, that's how it looks to me right now: the modular wheels they are. They seem to be working well, just with these two bolts in a lever to tighten down the wheels we're using a pen. Basically, a soccer pin for the wheel with a wheel mount that collar back there. That needs to go that doesn't doesn't do anything. These colors here are important. They hold the wheels in place and.

A

So we have the double double structure for the part front part I, guess the main part of the arm and then going to 111 tube on the bucket, so the cylinders serving as the other connection- that's basically it's so just returning back to the some other details here like we need to close this down. That gap here makes the tractor to why we can close that down by 4 inches.

A

These are hydraulic motors. Let's get some measurements so, finally, here basic design for the foot pedals. The way this works right now is that the tractor- this is actual feed hose from the power cube. That goes out the other side and then into the foot pedal valve, and this is the actual return line as far as the widths of the of the bucket and everything will put this piece away this here, we've got six feet here right now.

A

It was currently 77 inches wide, so six feet, four inches about six feet: five inches the pepper. This bucket is 27 inches.

A

This part here is about three and a half inches.

A

About 21 inches, the back side is 19 inches and that's the side on the bucket.

A

So that's about it and then just to look at we're using a metal sheet for the roof right now, as far as the seat mounting there's a four by four across, and this is sitting on a bunch of four by fours and this four by four mounts the valve played on here and that's some of the main details. Okay,.
