Toy dozer has RC potential!

[pumptech]

Looks like a fun project ,does the drive gear boxes have a slipper clutch ,if so, its a easy fix ,pull apart ,dap of superglue or hotglue ,look forward seeing push some dirt soon

Wow! That thing is huge! How much does it weight?
It's a little big for my pit unfortunately and it's a John Deere......... Sorry, ain't gonna happen!

Looks like the blade also is motorized?

Oh, one more thing. You think you will need extra ballast to make it work good? I would expect it to be pretty light weight out of the box.

It's really weak @ 6V and not sure how much more 7.4 will give but I plan on trying this weekend. If it burns out then the entire drive system comes out and I start shopping at robot shop or servo city

The blade is motorized with a huge plastic gear box that has to go. It won't drop the blade below level with the tracks. I might try to use the existing linkage system with a high torque servos.

Upgrading and added aluminum plating will add some weight but can't get too heavy or next problem will be the tracks....

Yup, I think it's very first time Rc conversion friendly

Haven't opened up the gear boxes and judging by the weak motors, probably no clutch. Blade has one I know

The timing is terrible for this project! It's a perfect winter plan but I got work for a dozer now! Which reminds me..... I have to put spreader chains on the dump truck!

Not sure if this is the right place to continue this thread but I've actually begun my first toy conversion to full RC.

Ordered some motors from robotshop , faster speed than I wanted but the right size , decent strength and cheap price.





Mounted up to the stock sprockets real nice...





The way the final drives were assembled from new bright, the covers are remove able so all is hidden.



Start hacking plastic .....



Reinforcement.....
















And the first test of the track speed @ 7.4V
