jenkinsph, thank you for the links and I have to correct another error yet again, the rating of the K58 is 629 NOT the 329 I cited, my thought process was working in the 50/50 split mode.
But boys you miss the thrust of the thread, lets talk about the weight rating/specs of the K58 AND the general level value when a maker chooses to use a sealed, non serviceable drive in a machine that is an awful lot more money than another brand that offers a much much higher level of quality of hydro drive.
This cannot be disputed, the BDU drive in the Cub GT2000-at $1,600 less than the X360-will run far cooler and last much longer than the K58 while doing much more work than the K58-this one can take to the bank.
