I did the petrol lawnmower thing start of last summer. Our garden is on a slight slope but nothing major – the self propelled function is great. You’d be surprised how heavy petrol mowers are compared to electric ones.
At £180 you probably aren’t a long way off a branded make that should have spares easily available. Maybe just check online / b&q etc. I got my mower from abbey garden sales in Tavistock – although I ordered it online.
Went for a lawnflite self propelled mower with a roller. Been brilliant so far – first pull this year and it started first time. Probably needs an annual service which I might do myself – but it ran perfectly after not being touched since about October.
Bit over the £180 budget though – but I got a. It excitable looking for a mower and like striped grass.
