Well, I got both tracks on for a test fit,  :dancingbanana:

The tracks are not tensioned tight yet, tomorrow I'm going to do more work on the undercarriage and track rails. I set the hood on to get an idea of what it's going to look like, I don't know how it's going to work, but so far it has a nice look :thumbs: :smilewink:

 

I also put on the blade mount, I think the gt is to tall for the blade to go down all the way to the ground, so I'm going to half to lower the mount.

 

I rolled a push mower up beside it to give a idea on the size, it measures 3' 4" at the hood, but I'm going to half to raise the hood a couple inches to fit the engine, so it's probably going to be 3' 6" when I'm finished.

Anyone know what kind of oil I should put in the hydro?

Right now it looks like automotive transmission fluid (it's red), I have some hydraulic/transmission fluid, the jug says it can also be used on hydrostatic transmissions, but they are also talking about big machinery like swathers, combines and ect.

Thanks for any info

Coming along.

What is the dimension from axle center to ground.

That'll make it easier to get an idea of height.

Interesting build. Where did you come up with the idea? Have you been around track types before?

 

I haven't be around much tracked machinery, just had a idea of what they should look like and then started building :thumbs:

I have always been intrigued with tracks and really all machinery/tractors and ect.

My family (on both moms and dads side) have been in construction since the very beginning, construction machinery is in the blood.

I have always liked building things and I've always wanted something with tracks, so this is what I've come up with! :rocker2:

Most of the time I'm weening it, but I guess that how you learn.

Not sure, I'll measure it tomorrow and see.

Here is a old thread I started a few months ago when I first started this project.

This goes into more detail on everything I've done

In case someone wants more details

For what it's worth, I give you a lot of credit for having the drive to take on a large, uncharted build on your own :thumbs:

But there is only one way to find out how it's going to turn out in the end, and that's the finished project. Good luck along the way, I'll be watching this one till the end :watching_you:

I use to own a Cat D4H and loved it. Look's like you're doing a fine job, my only suggestion is the bottom rear sprocket might have been better supported by the bottom rail going back farther. Could be fine, that area just looks like it could be a little weak. Great work though !

Thanks

I have been thinking about the lower rear sprockets too, I don't like the design I did, I have the fork shafts threaded, so I can tighten the nut to move the sprocket out to tighten the track. But the nut is to hard to turn, so I am going with a different design, now I have welded on a heavy piece of strap to the fork, I then cut a slit in the strap, I am going to weld two 5/8" bolts on to the frame, then I can pull the track tight with a chain and boomer. Then I can tighten the nuts on the 5/8" bolts and that should hold it (I hope)

This should also make it a lot stronger and hopefully it will hold up.

Hope this  makes sense :say_what:

Oh, from ground to the center of axle is 17" and from the bottom of the blade mount to the ground is 11".

I'm guessing that this is 6" taller then what it was originally???

Just thinking about your track tensioners. shouldn't they be spring loaded to push your tracks out? To keep "tension" on them. Instead of solid? Because if there isn't going to be any give in and out, something is sure to bend somewhere. 

Unless I'm reading something wrong, I'm getting the idea your using solid pressure pushing the front and rear away from one and other to keep the tracks tight.

(Easy for me to think what I'm thinking, but not so easy to explain.)

Solid... thats the way my struck is and we a tryig to figure something out for track tension.  I kinda hard to figure out how strong of a spring you need the will keep the track tight and not move and give if something gets between the tracks

I have a spring in the front, so if I get anything stuck between the track and the sprocket I wont brake a track.

If it doesn't work, I will take it out and try something else.
