Default mini dozer

I've pined over a mini dozer since I saw a Struck ad in a Popular Mechanics or Mechanix Illustrated as a young teen. I sent away for the assembly book back then, but couldn't afford the 2500$ or so kit price. It was way more than the folks paid for most of their cars

In the years since, I've collected and traded for assorted plans and finally settled on a modified build of the minidozers - all belt drive mini-dozer similar to the Struck RS 100 http://www.struckcorp.com/download/R...ctSheet_NP.pdf with a vastly different track assembly. . 3 or 4 more Saturdays and I should be making even more noises around the yard...

I plan to use a 13 HP Honda knock off. It should handle a 4' blade. I'm going to build tracks out of a chunk of 6" flat belt I trade a neighbor for.
Picture #1 is a double pulley for the reversing transmission
Picture #2 is the back of the original weldment now cut apart and redone (poor workmanship, sigh)
Pic#3 is a front idler hub
Pic #4 is a rear drive hub
Pic #5 is a better image of the drive hub assembly

It looks like you've got a start on the project.

I'm too lazy for such a build. I would opt for starting with a hydrostat drives or just refit a ZTR mower with tracks.

I would love to go hydrostat drive, but alas the funds and/or inventory are not there. I'm substituting 4 shafts and 5 belts for the hydro drive - less $. There is little reason the drive couldn't be converted to hydro in the future if a sacrificial ZTR appeared out of nowhere....

This will be interesting!, and I'll keep up with this thread!

On a tractor Forum that I ''used'' to post on.. There's a thread with pictures where a member turned an old riding mower into a ''mini dozer''!.. It's real nice!.. He also built his own tracks!

I have an old JD riding mower, and thought about turning it into a mini dozer!... Wife can't understand it because I have a JD 450 dozer

Lookin' forward to this thread!

Good-Luck with your build!!

Bill

So, I got this far and am now waiting on next weekend. I've already ordered the belts for the drive. Hope they fit...
1. side plates laid out
2. side plates welded on drilling rear axle mount holes
3. front quarter view with both axles in
4. view showing more of a side view
5. assorted pulleys for the transmission.

Cool project. I've also tossed the idea around of finding a ZRT and doing something similar. I've asked around a time or two putting out feelers for a used ZRT, but no leads yet.

This is going to be an interesting build, I'll be watching for updates! Do you have any plans or projects for the little dozer once she's done?

Looks like you're reaching deep into your resource pile, isn't it nice whe you can build a project from mostly scrap and scrounged items?

Yes, I'll be watching ths closely too, Cam. I got all enthused about building one back in the 80's. Started a new career and that was the end of that. In the end, I just didn't think I'd have that much use for one in a yard, just a little over 1/2 acre.
