I have the tractor parked on a concrete floor and there are no drips on the mower or the floor. I've looked over the motor thoroughly for leaks. The front main seal looks good, there was initially a slight leak from the rear of the tappet cover (re-torqued the bolts and solved this), the rear main seal appears to be seeping but is minor at this point and no way would explain the 3/4 quart I have already gone through.

Note, with my cub cadets I was using 10/40wt oil the top shelf Mobil super oil I used all my life, mowing my two acres(cadet) I was going thru a quart of oil every second mowing. I switched to a 30wt oil and it stopped using oil.
Interesting experience on your Cub Cadets, I'll keep this in mind. This would also be a good low cost option to try yet this mowing season. Were you using straight 30 weight, or multi-viscosity?
