@Tom Probably not, because it weights less and thus has worse traction.

@Sariel You are right, even when you put 2 PF M motors, they're still 7 studs long, or in technic measurement, 6M's. If you still have that bulldozer, you can try putting one on top of the other, and use some gearing to reach the Linear Actuator.

@Boris Yes, I was thinking of that functionality, but the main problem was that there simply was no space for one more motor or even a small pneumatic circuit. It would probably take a larger model to include that functionality.

Also, just wanted to say this to everyone, some bulldozers can pitch their plow left-right, so as a solution to that, you can use some LEGO Bionicle parts, or some LEGO Bionicle Balls, so, when I earlier said: “…two motors are going to power the plow…” I meant on tilting it.
So, you can just modify it a bit and put 2 pf motors, and some bionicle arms/legs with those ball things at the end, and when one linear actuator goes down and the other one goes up, it should tilt. =D

I am a big fan of all of your creations. =D Keep up the good work!

@alex No, I have no idea.

Hi Sariel

Do you know if there is already in some Lego blogs a comparison of Pneumatic Air Compressors?

It would make sense to know how much time it takes to fill an Air Tank with different combinations of Electric Motors/Number of Pumps.

Thanks,
Alex

tl8, I also have a NXT set, and I am working on a bulldozer, but two motors will power the front plow. It will be finished once I get a second NXT set, LOL xD
However AWESOME BULLDOZER! GOOD JOB SARIEL!!! I LOVE ALL OF YOUR CREATIONS!!!

very impressive job on fitting so many motors and functions into a chassis that small. well done, well done.

Very nice.

It somewhat puts my bulldozer into the right perspective. I now see I did have ok proportions (and I thought it was massively too tall(only mildly to tall )) http://www.orbiter-forum.com/blog.php?b=47

I did have the problem of not enough parts and very poor weight distribution as well as fitting the NXT motors in.

Keep up the good work, I really get a kick out of looking at your creations and seeing how you tackled the various problems.
