transmission fluid level check

[tbord]

Hi, new to the forum. i have a seal leak on the rear wheel of my emax 20 hst. my question is i need to do some plowing and wanted to check the fluid level before doing so because i dont want to damage anything before i get the seal changed. where do i check the level? i have read in other forums about a sightglass but i don't see one on mine. tyia.
