Hello All! I recently moved and have a much larger lawn. I currently need to mow 1/2 acre but I'm in the process of enlarging it this summer. By the end of the summer it will be approximately 1.25-1.5 acres. 1/2 acre is doable with a walk behind but I'm not ambitious enough to mow 1.5 acres with that method. Should I just get the riding mower now or buy the walk behind and then get the riding mower next year? Thanks. I would also like to mention that the lawn is currently very bumpy and uneven with a couple small hills.
