Modifying a blade is potentially lethal and would leave a business open for litigation- not to mention your public liability insurance would be null and void- definitely not something to recommend.
null and void.
If you want a mower that ticks all your boxes and is just the right size for your lawn, then you can't do much better than a Hayter Envoy 36. It has everything you need, is easy to use and store. Light enough for a lady to use without being a "toy mower" like your Power Devil. It is reliable, tough and durable. It has won pretty much every product test it has entered. Crucially it has a proper rear roller which you are looking for and there is great aftersales support and spare parts availability, so no worries there. Sure it's not the cheapest with an RRP of £189, but it will last many years, be reliable and do the job you want it to.
