I got a deal on this, but only need the batteries. Selling the mower. I have one in use as well. Just saying that to let you know you can use this with a pair of 5 ah batteries. Would do a small lawn of 3k. Or with a 8ah would do about 6k. Yes, theres a huge difference there. I'm using a pair of 8ah. Does fine for me. I need the 12ah for a mixer at work. Its still in the box. This price is tool only, no batteries or charger. But I will be selling the 5 or the 8s I have. If you need, just ask. _____________________________________ The MILWAUKEE M18 FUEL 21" Self-Propelled Dual Battery Mower Kit meets the performance, durability, and ergonomic needs of landscape maintenance professionals.
