New used mower

Ive always been a John Deere person. Ive had my share of them and they have always treated me good with no big issues. I currently mow 3 yards each week with mine getting done twice a week. My yard is about 1/2 acre of grass, the other two yards I mow are 3/4 acre of grass and a 1/3 acre of grass. All are neighbors so I dont have to trailer to get there. This year I may have to help out my mother in law to try and help her save money. Its my choice to do this, but it requires me to load and unload and trailer across town. So Im selling my tractor which is an all wheel steer 48" bagging tractor and Ive bought a Toro Z-Master 52" bagging zero turn. Im hoping this will all but cut the mowing time in half. Its not my first Zero turn as I had a Simplicity about 15 years ago but I never liked the turn marks in the yard it left. Im hoping Im over that now as Im not as concerned with that as I used to be. At this point time is more of my concern. I was never able to get everything done in one night where I think I will be now and if so I will have an extra night to work on the car. This thing travels almost double the speed with a much faster blade tip speed. Now I just have to hope it cuts as well.
