Yes I've trawled through the previous threads on this topic but they are all outdated and locked.

Our situation is that our old Troy Bilt ICE lawnmower has finally succumb to old age with striking a rock causing the mounting casting of the engine to fracture. As we have recently installed PV it makes sense to use it to run a lawnmower as well as our car, house & sheds.

From previous experience with lawnmowers my wish-list goes something like this:

• Substantial battery capacity as we are rural and have significant lawn area, though usually mowed in portions over several days.
• Battery compatibility with the De Walt Flexivolt (18V/54V) ones I've recently invested in as part of a power tool set.
• Disk with flails type of blade system and a metal skirt/body as hitting stones and the occasional tree stump is unavoidable.
• Reasonably wide swept blade area as I'm not into mowing our lawns in 1 foot increments.
• Powerful - weather and other commitments result in long grass at times.
• Catch or mulch abilities.
• Walk behind but not self driven.

I've seen plenty of less than positive reviews of the De Walt mowers so not sold on that brand for a mower. I'm not averse to investing in multiple batteries so long as the economics of this aren't prohibitive.

The disc blade system used to be standard issue on Victa lawnmowers and successfully reduces shock loading the mechanicals resulting in bent blades and crankshafts so pretty sold on this feature. Flail blades are also cheap and easy to replace but of the mowers I can find blade details for it seems bar blades are prevalent.
