The thing that becomes a problem in confined spaces is the Mow In Reverse lock out system.
In a small yard you end up doing a lot of reversing.
Some mowers simply allow you to override the system by the key position, others have you pushing in a button, & holding it in every time you go into reverse.
This is going to drive you crazy.
Then there is the way it works.
Some MIR system just turn off the blades so all you have to do is turn the blades off then on again.
Others kill the engine so it is stop, set the brake, turn off the blades then start the engine then turn on the blades.
This will cause a lot of pain in you knees, from continually kicking the mower in frustration.:laughing:
Go for a mower with electric blade clutch
