I've just moved to a place with around an acre of garden, lawn,

slopes here and there.

I bought a 5.5hp motor mower which copes fine but I find it quite
tiring and manoeuvering it quite hard on the shoulders and knees.

I now want to buy a sit on mower - but I know zilch about them. Can
anyone give me any guidelinesor their own experiences?

I've searched on the web but found very little other than
straighforward specs for the machines.

'Wouldn't be without mine.
If the ground is uneven then you are bound to scalp bits of it with
any mower ... and the more scalping it gets, the flatter it gets. I
have a Bolen 30" mulching mower with a 12.5 HP Briggs and Stratton
engine. Never had any bother with it. I would encourage you to think
of the 'mulching' type as disposing of an acre's clippings soon poses
problems. I have two 1 in 3 banks which mine copes with (although you
do have to lean into the slope!)
