Answer: 
You can take the part to the Home Depot where you bought your mower. They may have parts to fix this or they may be able to help you order one on line. If this fails you may have to find a Lawn Boy repair dealer and maybe they can help get the part you need.

Rated 3.6 out of 5 by 282 reviewers.
Rated 2.0 out of 5.0 by Real Lemon of a Mower My mower saga began in January of 2016 when I purchased this mower at Home Depot in Salem, Oregon. No immediate problems developed, and it seemed like a good machine at first. I especially liked the key start feature. Then, I let a relative borrow it. Returning it to me later, he expressed surprise at how easily the plastic battery compartment lid broke off. I addressed it with some duct-tape (as any ordinary guy would do), then decided to track down and order the replacement compartment. This was easier said than done, but I finally found the item and ordered it from Lawn Boy online. Installing the plastic battery compartment (for the TruStart feature) wasn't too bad, but it did take me most of an hour to complete the task. No more problems for several months, then the same compartment broke off again. As soon as I'd replace the top, it would drop off again while mowing. Next, the wire from that compartment to the key starter assembly kept disconnecting, Finally, it wouldn't even connect back to the key assembly. So, for a mower I still consider new, I have parts falling off and disconnecting from one end to the other--or so it seems to me anyway. Is this a lemon of a mower? Yes, but it didn't have to be. The mower itself is a good machine, but the way the TruStart features are added on makes it the machine's weakest link. Instead of sheltering the battery compartment or making it of a sturdy material, they affic it to the mower's edge (above rear wheel). Anytime you lightly brush against something, you're putting your TruStart battery compartment at risk of breaking. On top of this, the bag is cumbersome to re-attatch. It's started falling off regularly now, too. Really poor engineering, except for the engine itself. Having a great engine alone, though, is pretty useless unless it will come outside and mow the lawn itself. I am attaching a photo of the machine, but this is before it seriously began falling apart.

Rated 1.0 out of 5.0 by Lawn Boy The only good thing I can say about this mover is the engine. Mover itself is poorly designed. Self propelled transmission works fine but... Height adjusting mechanism for the rear wheels is too wide and the play (left-right) is too great. Because of that it falls of the metal bracket onto plastic rolls. Rear shaft from the transmission scrapes on the inside of the wheels on both sides. It even blocks them from time to time causing terrible scratching sound. See attached pics. No adjustments can be made since that part is welded that way. Past 30 days. Wasted money. May 8, 2016
Rated 4.0 out of 5.0 by I like (not love) this mower. I'm a 29 year old female and have been mowing lawns for 20 years. I have a small yard with sand-based soil and some large lilac bushes, so it was important to get a mower with rear-wheel drive. My Craftsman lawn mower broke down with only a month left of mowing season so I wanted to buy something inexpensive. I paid just over $300 for the Lawn Boy and have used it twice - once with the bag and once without. The gas start-up is not as good as it claims to be. It usually takes at least 3 times. The bag does not seem to collect as much grass as it should - it gets stuck underneath. Also, the bag's opening is kind of an awkward shape, so it's difficult to get the grass from the mower to a yard bag. I like that the mower is fast, that was one of my biggest gripes on my Craftsman. Overall it's a decent product, especially for the price. October 25, 2016
Rated 5.0 out of 5.0 by works great and makes mowing very easy. October 25, 2016
Rated 4.0 out of 5.0 by Lawn Mower Love this lawn mower, bought one last year for me and my son uses it all the time. Got tired of going to get it back, so bought me another one for me at his expense. Only problem we have had is that the metal drive gear on the plastic wheel wears out fast. But I think all mowers have this problem for a decent price. If it stops working, will probably buy another one if Home depot still carries it. September 29, 2016
Rated 1.0 out of 5.0 by Came defective It came with front wheel off which when put back on kept sliding out causing the height lever to drop to lowest level and scrape large spot on lawn. Tried to fix had to return to store big inconvenience for a single woman living alone being as it was very heavy with the battery October 4, 2016
Rated 1.0 out of 5.0 by Quality was not what was expected This mower was light and had the nice feature of electric start. However, It did not hold up after 10 minutes. The front wheels came off while mowing and were ruined by the blades. It was unusable after that. Also, the rear wheel drive seemed a little weak. Too bad, because its hard to find a decent light mower. September 18, 2016
Rated 1.0 out of 5.0 by Short Life Span - Multiple Issues I purchased this mower from Home Depot in middle of 2014 and it performed as expected that year on a 1/4 acre size grass lot. The following year it began surging and I took it in for maintenance. Oil, filters, and spark plug were changed. It wasn't long before surging and a newer issue - oil began seeping out of the carburetor ( suspect a breather valve issue?) into the air intake which required several trips to buy a new filter. This got expensive, and the problems got worse. A few weeks ago the mower started spewing oil out and this is when I took it to a reputable service center. The service center told me the cylinder and rings were damaged and there was no compression in the cylinder. I asked how could this be, being only a 2 year old mower and always meticulously maintained ( had previous mowers last 20+ years). To my surprise I was told these big box stores carry the price point lawn mowers - and that they see them last somewhere between 3-6 years on average. Lawnboy and Kohler all declined warranty coverage since it's out of coverage by a few months for the "2 year engine warranty". Words of wisdom, DO NOT BUY THIS LAWN MOWER. You get what you pay for. If you can afford the entry level mowers in the "higher lines" that are actually sold by mower shops, those mowers are made with much better materials and are meant to last 10+ years.
