Ryobi 40V HP Brushless 21" Self-Propelled Mower Kit (RY40HPLM01K2) review

The Ryobi RY40HPLM01K2 gives the most runtime per dollar of any mower we compared. For $639.00 on Ryobi's own store, the kit includes two 40V 6Ah batteries and a charger, and Ryobi rates it for up to 80 minutes of mowing and yards of 3/4 acre or less. That is double the 40 minutes Toro quotes for its 60V Recycler with one 6.0Ah battery, at a similar price. The drive is variable speed rear-wheel self-propel, and the Cut Command Center on the handle shows runtime and blade life and lets you switch on turbo mode, the lights and the drive speed. Ryobi says the mower delivers more power than a 163cc gas mower. A lever-operated mulch plug switches between bagging and mulching, the bag pulls straight out to empty, and the handles fold for vertical storage. The gaps are in the published specs: the product page we checked lists no weight or cutting height range, so compare those in store. The 40V batteries also run only Ryobi's 40V line, which Ryobi says has over 85 tools.
