Using my 24HP Cub Cadet with 50" deck it takes about 3 hours to mow the entire lawn out here, at the front of the house, both sides, the back and a tiny bit of the field.
When I use to live at home, mowing the lawn was my job. It took 25 mins to cut the back and 10 mins to cut the front as my parents house has a really small front yard. I would listen to music while mowing the lawn.
That's what I like about Winter in the UK, It's so cold and raining or snowing that it doesn't grow that fast and so half of the year I get to not to cut it.
Our small backyard is planted to grass so we have a lawn somehow. The grass needs to be trimmed regularly. We don't have a mower for the job. What we have is the grass cutter that is a big scissors. We pay someone to handle that task because I don't have the perseverance and the enthusiasm for that work.
No grass in my garden, not much point, also I don't do anything with my garden since I personally have hayfever! So, yeah, there's plenty of dirt down though. So if there is rain, we are doing our bit to absorb it atleast!
