My mini dozer build

[OTHill]

Here is my latest project. Spent most of a year at it. Has been very satisfying. Engine is 3 cyl. Kubota 20 hp. Drive is fully hydrostatic from a wrecked Massey swather I had given to me. Drive motors are 29 cu.in orbit motors from Princess auto. Brand new mini excavator tracks the single largest expense in the project. Didn't keep track of total time or expense but must be 1500 hrs and 5 or 6 thousand dollars by now. Any parts that could possibly be plasma cut I did on my 4x8 ft. Cnc plasma table including front idlers, rear drive sprockets and track rollers. Total weight might be 1200 lbs. Just guessing though. Top speed is close to 5 mph. Planning a 6 way dozer for it yet to. I'm very new at posting this kind of a thing so please bear with me.

Nothing I like watching better than homebuilt dozer ****. How are you tensioning your tracks? What hp is it? What will be it's primary use? Oh yeah, welcome to TBN!

Yup and he's deep in a project enjoying himself like Billstmax (youtube) used todo before filming was stopped in the graveyard garage.

THAT is a VERY SWEET looking machine!

Very nice build! Whats going on the back for weight?

 

[Xfaxman]

A 3 point hitch would be handy.

 

[ArlyA]

Neat! Please keep us posted.

So far not noticeably light in the back. The fuel tank is under the seat and the back and sides of it are 1/4 inch plate also the hydraulic motors add some weight back there. Originally when I started I was planning a front end loader but needed to move dirt on a new place sooner so bought a 2520 JD with FEL so I'm planning a six way dozer now for the crawler. There is an auxiliary hyd.pump built into the hydostat.pump that I will use for the dozer. Right now it's just returning to tank. Don't have a lot of pictures of the build but will send some of various parts.
Completed frame after paint.
Grill and some track frame parts.
Fuel tank fan shroud hyd.tank and front grill mountEngine and belt tightened bolted into frame
Front idlers and drive sprockets

VERY nice! Where do guys like you find the motivation to finish a project?

I find it so much more fun, planning, sourcing and buying stuff, than actually doing the work AND running into problems.

 

[EddieWalker]

This is going to be a fun project to follow!!!

 

[Jstpssng]

I'm going to enjoy following this one! I envy people with the talent to do this kind of project.

OTHill,
What tensions the tracks?

My guess is, where the red arrow it looks to me to be somewhat of an extensible slider, so there must be some adjustment hiding behind.

OUTSTANDING!!!

The adjustment is a screw jack:

 

[OTHill]

Yep it's a screw jack. I'm still debating if I need spring tension or not in case a stick or rock gets into the track.

 

[OTHill]

The sliders are 2.5 x2.5 sq.tube inside 3x3x .188 wall.

That’s just cool beans! Don’t know much about dozers except I like them.

Like the pictures detailing the fabrication. Good skills. I’m just seeing two bolts, thru tubing, securing each track to the frame? Enjoy following your post.
