Re: (ET) Mower deck starting amps

[Rob Brockway <getractor yahoo com>]

 I picked up a recording DC amp meter last year.  Here are some readings I 
took at about 4 samples a second.

Keep in mint the locked rotor amps will be very fast and hard to catch.  
This part of the curve shows that it is back to running amps in about 2 
seconds.


I might guess that the armatures have .07 ohms combined in parallel.  
Ignoring the voltage drop in the battery amps = 36V+/.07 ohm= 514+ amps.
I am interested in trying new battery but have been worried about this 
very issue if the BMS would be a problem.  What is the size of the battery 
and rating of the BMS?

 I recently bought very expensive lithium battery for my mid mount new 
idea tractor.  The tractor works beautifully, however the bms shuts off 
the instant I try to start the mower deck.  Does anyone know what kind of 
current the three Dr k motor require to start and then run?

Thanks.
