[damjan97PL]

HI Everyone.

Toady I want to prezent you my newest MOC, a bulldozer.

Dimensions:

-Lenght: 40cm

-Height: 22cm

-Width: 23cm

-Weight: 1850g

Model is very simple mechanically.

It has a 2 XL motors steered independent for propel with 1.66:1 ratio.

Front blade is operated by 2 large LA and propeled by L motor with 1:1.66 ratio.

Rear ripper is lowered by worm gear with toothgear z24. All mechanism is propeled by M motor with 40:1 ratio.

The front blade and rear arm have enought power to lift all vehicle up.

A cabin have a openable door and driver seat with suspension. SBrick cube is also in the cabin.

A BatteryBox is in front part of vehicle.

Caterpillar tracks have a simply cradle suspension.

Model drives nicely good, but it jumps a bit while driving. 

Overall i'm happy with performance and look. It's not perfect but I like it.

I'm waiting for your comments :)

Looks pretty good - the gaps in the blade throw me off a little bit, but I like it.

A bigger wheels would be perfect for it but it is still a original dozer.

Looks to me like a cross between a Caterpillar D9 and a Chetra T6.

Funny story, I was driving back from a hike over the weekend and passed a place that had a bunch of excavators in the yard, with their name on them - learned of Sumitomo-Kenki heavy equipment

I love those sites but I never went into one of them, the last brand I discovered was broyt and I will do one as soon as I had the new linear actuators.

Nice bulldozer! I have a weak spot for them. Were you inspired by a real model, or is it your inspiration? Interesting approach to build the XL motors vertically. The rest of the motors are nicely hidden. I in particular like the suspension seat! What I find a bit disturbing when watching the video is that the back ripper vibrates a lot when riding ...

It's beautiful

If i exept the not vertical position of the actuators this model looks great and seems pleasant and fun to play with. I think you have done a great job. For improvement I let you here my thought.  Maybe it is possible to mount the actuators upside down so you could drive them from the back of th model and build a connection between the moving arm of the LA and a lift arm connected to the blade. Just my thought. This retires nothing of to the overall quality of your model.

There is to much slack in the tracks, at 1.22 in the movie you can see. Remove one link, or give more tension would help
