I was figuring I would always need a push mower even if I had a ride on so I think I will start there, I may have to mow it one more time before fall, we shall see, they mowed it right before I moved in
Soon it will be cool enough that you won't need to mow, so you can save your nickels until spring and get the rider at that time.
Get a good quality push mower and keep the oil changed every year, and don't run over any rocks or pipes, it will last many years. You're only decision will be if you want to bag the grass or not.
I prefer one that is not self propelled, I can cut faster with it. It's good excersize.
Depending on where you live and how much rain you get you may need to cut every 5-10 days. Which means you may want to cut a 1/3 to 1/2 a section a time. An acre will take most of the day to cut depending on how high the grass is. If you divide it into sections your not using your whole saturday or Sunday cutting and trimming. On a really hot day it can really seem like more work than it is. Remember, the higher it gets, the longer it takes to cut. If you are going to bag the grass it takes longer because your going to have to stop and empty the bag. I don't use a mower with a bag feature. When I want the grass for compost I rake it and wheel barrow back to the bin.
If you spend 20-30 minutes after work, by the time the weekend comes around your yard is done till Monday or Tuesday:drink:
