RE: (ET) Tractor ride not smooth

Right you are.  Because so few people have belt-tension gauges GE didn't 
bother specing that way.  That's also why most modern FEAD's (Front End 
Accessory Drive) on cars have spring loaded tensioners.  Typical tension 
for a multi-V is 110 to 130 lbs.  The force on the bearings is TWICE that 
(assuming 180 deg. return).  Pretty high force on the bearings.  Single V, 
like an E12, I go 140.  I have had belt squeal in snow-plowing with less.  
Part of that may be the cold belts.  The problem with a dual-belt is you 
have to replace them in sets and re-check tension after the tighter has 
loosened up a bit.

 The more tension you put on the belt the more wear you place on the
bearings in the motor and transmission. With the dual belt system you do
not need to tighten it as much, so the bearing have an easer time of it.
Not sure it matters much in a garden tractor that gets 50 hour or less
of use a year, but I plan on keeping mine for as long as I need to mow.

 One of the two places I may end up in may not need an Elec-Trak for
mowing. One place is too hot for grass to grow and the other has a rule
against tenants doing outside landscaping, after all it's a gated
community!

Ummm....  Yes, it's there, but it doesn't get an E12 belt tight enough
for snow plowing.  I've tried.  Prying works better, Use the 1/4" shim,
tighten and mark the location with a pencil.  Then loosen the bolts, and
tighten the 
belt another 1/16" of an inch or so.  The easiest way to do this is with
a belt tension gauge (I borrow one) and a 
big lab-jack between the trans & motor.  Not just that, you need a POWER
RATED BELT!  Get 5hp+ (I get 8hp).

Learn something new every day.....

I thought I'd read all the manuals, but never saw that - much nicer way
to
do it. Sorry 'bout passing on my 'shade tree' method!
