RE: (ET) Snowthrower and weights

I have a bucket loader, a rear weight box and wheel weights. A correction to the post below - because wheel weights are on the wheels, they do not contribute to bearing wear. They are not supported by the axles, but rather by the ground through the tires and wheels. Furthermore, wheel weights have a lower center of gravity than weights in a rear weight box, so they are a bit more stable under some circumstances. If you are using a power hungry snowblower or bucket loader, having a set of batteries in the rear box has some appeal, but could the on-board charger stand up to the load? Frankly, six more 6 volt batteries is too big a load, but when I got my 'Trak it was equipped with three 12 volt batteries in the box. Is this a technical no-no?

Although it will not offset the front weight, but will certainly add
traction, you can add wheel weights to the wheels. I know with my John 
Deer,
I added double wheel weights and filled the tires with liquid sodium. This
made a huge difference in traction for my plowing.

Maybe if you are not concerned with the bearing wear, you could add wheel
weights, fill the tires, and add a weight box. You would then have to be
careful that you did not accidentally hit your house as you might just 
slide
it into the backyard! LOL!

I plan on building a rear weight box to slot into the frame.  Two pieces of
1-5/8" x 1/4" thk flatbar bolted to a steel painted rocket box from army
surplus should I need the extra weight.  I've got dual cast iron wheel
weights for #110 per wheel.  With the chains it should hook up OK... I 
hope.
When I powered the snow thrower up, the dash meter read just on the high
side of the green band.  I'll use my clamp meter tonight and get some real
numbers.

Thanks again,

Bob.

Yep. Worse than that, it's all on the nose of the Elec-Trak, especially
when you've got the thing lifted with the lift. Then it's a point weight
ahead of the nose.

Wait till you power it up and see what it does to your battery pack :-)

I strongly recommend putting some serious weight as far back on the
tractor as possible to balance it out. With all that weight on the nose
you put a lot of stress on the front wheels and steering will skip to
say the least.

I weigh down the back with the weight box filled with old Hawker
batteries. I can fit 12 batteries back there, which is about 250lbs.
Since you're moving around a moment arm (the rear wheels) the further
back behind the wheels you can put the weight, the better.
