Good product
I bought it for my husband to use, easy for him to use since he had couple of strokes and can't use his left hand. Having a rechargeable unit is best.

Love my first mower!
I am a single 40 y.o. female and decided to buy my own lawn mower after 3 years of paying for lawn service at $600 per summer. I feel I got a great deal from CPO paying less than $300 for this refurbished electric mower. [...] I finally got to use it for the first time on my small yard this week and it was so much fun! My yard is just under 5000 s.f. and easily finished the job on a single charge. My yard is mostly flat, and I didn't think the mower was too hard to push. I bagged the clippings and the bag was just large enough that I didn't have to empty mid-mowing. My neighbor totally wants to borrow my lawn mower, too!

great for smaller yards
I purchased this mower to replace/supplement a manual reel mower. It arrived fully charged and assembly is easy, just attach the pusher arm. incredibly quiet, definitely wouldn't wake anyone up in the morning. can bog down some in very dense or tall grass. However I don't expect to encounter tall grass much anymore as I don't see myself procrastinating so much with this mower. 1/4 acre is a bit much to cut regularly with a manual reel mower when you've got a busy job.

Regarding the battery.... although this model does not come with a removable battery pack like the other cordless BD mowers, I consider that a blessing in disguise. The chassis is deceptively empty with the cover removed (6 t-20 torx screws). Inside are three small, lonely 12v 10ah lead acid batteries. When they eventually fail, higher capacity batteries are readily available online for anyone feeling handy enough to do a swap. a set of 12ah (20% higher capacity) batteries could be obtained for less than the cost of the battery pack that B&D sells for the other models with removable batteries.

This mower is easy to use. It is easy to assemble from the box. The instructions say to charge the battery for 12 hours before use but it was ready to go after 2 hours and mowed my entire lawn. Grass was evenly cut and looks great. The mower is quiet and easy to cut around trees and schrubs. I would highly recommend this mower.

I like this mower
This mower comes in handy keeping fall leaves in control with its mulching ability. I don't expect to use the bag or to open its chutes at all. It mulches well, though it tends to try to send clippings out to the right thru the blocked chute. Also, the plug for the back chute (for the bag) tends to catch debris at times. I have to keep clearing it out. Still, a nice machine, good price. I'm happy with it so far after a month of ownership.

Impressed by B & D Products
These battery mowers are expensive. The re-conditioned helped to sell me plus reading about other mowers; I thought this was a good buy. I have a great cordless weed whacker from B & D and this is a very good complement. Not a lot of experience with battery but so far I am pleased.

Quiet Mower, with a Long Lasting Charge
I was Surprised at this mower! This thing is VERY quiet, all you can hear is the blades whisking around. The battery charge lasts alot longer than expected. I was able to do my front AND back yard all in a single charge, and it felt as if there was alot more "juice" left in it to do even more. My neighbor wants one now.....

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
