Re: (ET) Mower stuff

Another mower point I ran across in a service bulletin.  Interesting in 
that
it confirms the concept of running backwards possibly working better.

Mower Performance

The Elec-Trak mower is, as you know, convertible to either side or rear
discharge. The rear discharge mower is best suited to regularly cut lawn,
sweeper pickup of clippings and, of course, it offers major safety
advantages with all discharge down and under the tractor. Some lawn
conditions such as long, limp or wet grass and no sweeping are not well
suited to the rear discharge kit due to the front baffle pushing over the
grass immediately before the blades hit it.

The side discharge kit design is best suited to long limp or wet grass and
leaving the clippings on the lawn. The large space between the mower front
and the blades without baffling, and the rear baffle vacuum action for a
second cutting, combined with the broad scattering of the discharge, give
the cleanest appearance.

Each customer should be carefully introduced to the two options to best 
meet
his own application. If any mowing appearance or safety problems develop
later, the option for changeover should be explained to him.

An easy test for difference is to operate the tractor- rear discharge mower
in reverse and observe the appearance. In this case the rear discharge is
acting like the side discharge does in the forward direction and provides a
good comparison before making the changeover.

Mower Alignment

If a uniform cut is not being obtained with the mower, some checks to be
made include:

See that the blades are all in the same horizontal plane by comparing 
lineup
at the ends. Rotate each blade 180 degrees to test each end.

Check the front castor supports for uniform attachment to the housing.
Slotted holes in the housing may permit a difference in assembly if not
carefully checked.

Be sure the rear roller is assembled straight.

Be sure the mower is level by correct choice of spacers in front to
correspond to holes in rear adjuster.
