(ET) How to drive my shredder?

["Chris Tromley" <chris_t microtrac com>]

This is really an Elec-Trak question, but I've posted it to the EVDL too -
lots of tech-heads, and responses might serve to improve understanding of
different motor types.

Earlier this year I moved to a new house.  Bigger lot, more trees, same
amount of time (too little) to deal with it.  Bought an electric tractor.
Works *great*.  Cuts my mowing time WAY down.  Now it's fall.

Y'know what?  50+ trees drop a LOT of leaves and needles.  Raking takes too
much time.  So would blowing.  Feeding them to the shredder takes too much
time, so would bagging them.  I'm *not* doing this again.  Solution?  Mount
my electric chipper shredder
(http://www.patriot-products-inc.com/products.htm#eleccsv) to a tow-behind
cart so I can finish the job in a few hours.

Here's my question.  What's the best way to drive the shredder?  The 
tractor
runs on 36 VDC.  These tractors can run some very power-hungry attachments
with current draws up to 200 amps.  The chipper/shredder has a 1.5 hp motor
with the following specs:

Mfr: Magnetek (no info at website)
Cat. # 8 -184510-02    HP: 1.5    Type: CP
Volts: 115    Amps: 13.0    Hz: 60
RPM: 3450    AMB: 40°C    SF: 1.00
Time: Cont    Code: G    Encl: TE
FR: F56C2    Form: KMW

As for the RPM, a hand-held mechanical tach reads just over 3500 rpm.  The
motor has two bulges of different lengths on the case (starting caps?).
What kind of motor is this?  Specifically, what kind of inverter would I
need to drive it?  Could it take a crude excuse for a sine wave or does it
want the real thing?  What rated output should the inverter have for
reliable use?  I'd also like to run my B&D string trimmer off this, but I
think your typical universal motor doesn't care much about wave form?

If the inverter to drive this motor is too pricey, I'm thinking I could 
swap
the motor for a DC unit and run it direct from the tractor.  Suggested
sources?  Then I'd just get a cheapo inverter for the string trimmer.  Am I
on the right track here?
