I do realise I could do this myself but I don't have all that much time or space to make it happen.

I have no problems paying a small premium to buy one that is already done. That said as long as it is of reasonable quality and will offer some longevity of use.

My only last concern, and this is more in relation to reel mower use, is that my back lawn does have quiet a lot of litter from a gum tree. My plan is to run over it with the rotary mower first, on a high setting, to suck up as many of the gum nuts and leaves as possible. If there are a few gum leaves that have fallen through the lawn do you expect that will be an issue with a reel mower?

Basically ill do my best to have it as clean and free of debris prior to using the cylinder mower, however are the gum nuts that I have missed going to screw the reel up?
