Allett Cambridge 43 Cartridge Change v Kensington 17H Cartridge Change 

When using the scarifier or verticutter, what height do you cut the grass before you use these cartridges pls to pick up maximum thatch etc? Thanks

Does this not just show that you've made it purposefully finicky on the cheaper mower to force people to buy the more expensive one? Id love to invest in an Allett mower for my average sized garden, but this alone is a huge put off from buying the lower end models that suit my budget and garden size.
