Hello guys, I need a little info. I've only done small residential up till now. Have a guy wanting an estimate on 2.5 acre property. I use a 52" hydro exmark walk behind, and I'm not sure how long it will take me. It's almost all open except for right up next to the house. Any input will be greatly appreciated. Not sure how many acres an hour you can mow with a mower like this. I'm thinking 2 but I'm not sure. Thanks in advance.
