A nice toy for a half acre rough lawn if you have potfulls of loot.
I can just see me dealing with my 2 acres of lawn studeed with islands of trees, three ponds as reed bed systems, the stream running through it and the free-ranging chickens, the paths and soft fruit and espaliers... A lifetime of prgramming and running after the thing refuelling.
And as for 15 acres of rough steep pasture with bracken and weed trees and some variable boggy bits...
