Re: (ET) Leaf vacuum attachment

Hi Charlie!
Thanks for the reply. So it's 6 inch tubing and not 8 inch, where did you get your tubing and what kind of adapter worked for the Elec-trak deck? I have a spare shell here, and one of the reasons I am fixing all these broken mower motors is because I want to build it as the vacuum deck (my mail deck has the rear discharge baffles, this one has no baffles)
The attachment is pretty nice: It goes into the stabs and then has a connection to the tongue and another tongue coming out the back of it for the trailer so it won't hang up. Pretty clever.
Hopefully I will have a pretty balanced impeller, I just put it together and was going to try it out at 36 volts on the tractor. We shall see what happens.
For the trailer I think I'm just going to build a wooden scaffold and secure it with deer netting for the first year, then think of something a bit more permament if it works. This really is only going to be used for a season, so I'd like something that can quickly break down for storage.
Also I dragged my E15 hulk out of the back weeds and am going to put it together again. It's been about 2 years since I used it, so we'll see how much of a mess it is. Anyone know what size rivets to use to secure the front side battery box plates to the aluminum grill and such?

I had to build the stab-mounted rear frame from vague pictures, and it's an important piece.  Steve Naugler mounted the blower on the back of his E15 without it, but I didn't like the cart grinding against the blower housing on turns.  I'm glad Harold was able to find you one.
I'm using 6" (I think!) wire reinforced transparent hoses which makes it theoretically easier to spot clogs (which I haven't had) and lets me monitor the flow of chopped leaves at a glance.  The hose runs from the front mower deck along the right side of the tractor and up over the rear fender and has very little ground clearance but doesn't drag. Works GREAT, but would probably be even better with a belly mower.
My big leaf collection trailer is pretty rusty and I'm planning to cut the cap/hood down to fit my slightly smaller cart and scrap the big one.  The big one holds vast quantities of chopped leaves, but I'm tired of having two carts cluttering up the stable... I have to drag everything out to work on my casting foundry.
The chopper turbine blade is very heavy, and the better balanced it is, the happier you will be, I think. Vibration is an issue, and noise too. I strongly recommend you spend some extra time on careful balancing (although I haven't any techniques to share, Steve did mine).

    Ok, I think I have a good clue. Goska linked to a post about the
    bearings which states that the drive motors used 6203 and 6205
    bearings.
    RJ sent over a PDF document which showed the breakdown of the motor
    types.

    It looks like this is an e10M motor which uses the same bearings as the
    large mower motors. I can tell this because unlike the E8M motor this
    one has the armature go all the way to the fan attachment. So according
    to the PDF, this motor uses the 1007 and 1008 bearings.

    So if the right bearings are 6203 and 6205 bearings then I should just
    buy a case of them and swap out the bearings on my older deck motors
    and
    this one. Then on to the next problem.
