I know of 2 not being used, sat in a dusty shed next to various farm related gubbins
We've got one that has hydrospastic gears, and I think its around 2.5' cut. just needs a new fuel pipe and a feed pipe to the grass box. When it worked it cut well, not got a mulching kit for it though, but it did come with a tow bar!!
Or theres the old one which needs new belts and blades, you could cut grass at 10mph with that!!!
Again not the size cut youre after though.
Failing that there's the 5' pasture topper but then you'd need a proper tractor for that
On a serious note we are looking at selling the 2 mowers off and getting a reasonable one.
