I know, this will sound really stupid for some... but does anyone have any idea what actually fits in and stays in the Scag Tiger Cat cup holder??? I've tried a bunch of different things and nothing works. We are in the market to buy another zero turn for another property we have and I can honestly say the cup holder thing will be a deal breaker. I can't mow for 5-6 hours and have to stop each time I need to hydrate. Thanks!
