Red Technology Hour Meter Display

I'm looking at a used Exmark Diesel that is being sold on an online auction. The auctioneer says it has 486 hours, but this is what the display says. Is anyone familiar with this models display?

To answer my own question, the 177 means an oil change is due in 177 hours, and 577 means the hydro oil needs to be changed in 577 hours. They count down which confused me. The hours are 485.3 which count up and can't be reset.

I didn't buy this one, but I bought one like it
