(ET) Vacuum running, man does it draw power.

[Chris Zach <cz alembic crystel com>]

Re-configured the vacuum attachment. I have a bag behind it and was 
dragging the bag but that's going to rip it. So I took my trailer, 
removed the front panel and put the bag on the trailer so it now has wheels.

Works... Well. However the combination of drive motor, deck, and blower 
pulls a lot of power from my BB600 batteries. I can't put on the 
external battery box so I'm limited to 90ah of cells. Which drain in 
about 30 minutes of mowing/leaf sucking.

Need to do a bit more work on this, but it does work. However I can see 
the value of T105 cells in this case, with 180ah of capacity they would 
probably handle this load a bit better. Then again my BB600's are 
probably 20 years old with another 80 years of life left....
