My 2024 model has no reservoir tanks. There's a 3/4" top fill plug and a side port plug. I was told to remove the filter, drain the oil and then refill through the top fill plug till the oil starts to come out of the side port plug which I also removed. Based on my serial number the amount of oil to fill was to be 56.5 oz. I filled 55.5 oz when oil started to come out of the side port plug. I'm guessing there was 1 oz still in the gear. After waiting for the oil to stop coming out of the side port I replaced both the side port plug and top fill plug. I started my mower and pushed the steering handles back and forth till any noise disappeared from the gears. Did I do it correctly? Did I miss anything? I seem to be one of the first to change the gear fluid on the BadBoy mower without reservoir tanks.

You are supposed to raise the rear wheels off the ground (jack stands) and purge the air out of the system per the owner's manual instructions on page 12:https://www.hydro-gear.com/wp-content/uploads/2023/03/BLN-52441_2800_3100_3200_P24.pdf
First time with the bypass valve open and second time with bypass valve closed. Rinse and repeat as needed.

Are you speaking about the breather vent? If so, I thought any additional air would escape through this vent.
Minute 0:43 shows the bypass on this Scag. This video shows the correct procedure to avoid transaxle damage. Keep everything operating-room clean.
Ok. Thanks. BadBoy calls them bypass levers or neutral bars. They need to update their manual for those with internal expansion tanks. I don't have exterior reservoirs like yours for hydraulic oil. There's no mention of how the breather vent next to the fill port works either.
