3 reasons not to buy

  • Some customers have reported dissatisfaction with the Senix LSPG-L3's wheels, which they perceive as being of cheap quality, along with issues pertaining to wheel alignment. These concerns may impact the mower's maneuverability and potentially compromise its long-term durability. (12 reviews)

    • “One fellow said some of his wheels were out of alignment. This is probably due to a minor flaw in the stamping die or stamping process, not the inadequate thickness of the deck.”

    • “The Senix's wheels are cast in much thinner plastic than the Murray's and the axle is thinner. They are mounted on plastic extensions attached to the metal central portion to which the engine attaches.”

    • “The biggest complaint I have is like everyone else, these wheels are cheap and not very well built.”

    • “My biggest concern is how long will the wheels last. Fisher price bubble mowers have better wheels.”

    • “Mower delivered with with a bent rear height adjustment.”

    • “The wheel assembly looks inferior.”

    • “Front left axle clamp arrived shattered”

    • “After mowing for the first time I noticed that the left rear wheel was not aligned properly, indicating that the deck had bent.”

    • “The only bad thing I can say is the back wheels rub the bars to the handle depending on which level you set your wheels.”

  • Customers have reported issues with locating replacement parts for the lawnmower, and customer service has not been helpful in resolving these concerns, leading to frustration and a recommendation to avoid the brand. (11 reviews)

    • “I dislike not being able to find replacement parts and the agent had no idea if they had the parts on a lawnmower delivered this week.”

    • “Upon opening the box I discovered it was missing a critical bolt. I could not find a replacement bolt in Home Depot or Lowe’s.”

    • “Currently awaiting support from their service department but apparently 5-7 business days is typical for support requests right now. Not particularly pleased.”

    • “Due to this I'm missing a single washer for one of the wheels and have to go find a replacement.”

    • “There are no spare parts ( blades ) for this mower anymore. The SENIX web site does not show any spare parts at all for mowers. MORE IMPORTANT - the SEARS web site comes with the following message:"The manufacturer no longer makes this part, and there's no substitute part"”

    • “Called and e-mailed SENIX in attempt to get some missing push handle bolts and wing nuts. No callback or return emails.”

  • There is concern regarding the quality and durability of the blades provided with the unit, as well as restrictions on the ability to use aftermarket blades, which limits options for replacements or upgrades. (8 reviews)

    • “My only complaint is the cheap blades that come on the unit. They are pretty flimsy and come with a keeper that prevents using after market blades that are a better quality. I hit a small stick with it and it bent the liv8ng snot out of the blade.”

    • “The blade mounting holes may rule out aftermarket replacements.”

    • “If you hit a stone the blade sends the shock direct to the crank, and bolts that connect the engine to the cutting desk. Easy to wreck the entire tool.”

    • “Mower blade also bent immediately when hitting a stump as height adjustment wasn't able to get high enough due to defective part.”

    • “the piece that goes on the back goes up under the mower when you back up and blade has cut some of it off”

    • “the blade of the mower was seriously bent. Now - every other mower I had so far never had this "root problem"”

    • “Like another reviewer, the blade bent and I also absolutely can not get the bolt loose to replace it.”

    • “the mower blade is made out of tinfoil”

Bottom Line

The Senix LSPG-L3 mower is a hit with folks for its ability to provide a tidy, consistent cut across different grasses. It's a breeze to push and simple to put together, even for novices. The Briggs and Stratton engine fires up quickly, ensuring less hassle before getting to work. It's a no-fuss tool, great for everyday yard care, with adjustable heights and the strength to tackle thick grass. Plus, it's quiet and tucks away easily. But, be wary of the flimsy wheels and trouble finding spare parts, which can be a real headache.

    There are three holes that the wheels can be mounted to. Remove the wheels and reattach them to the desired hole to achieve the preferred cutting height.

    The handle is not adjustable in terms of height once it is secured to the mower with bolts near the rear wheels. However, it can fold down for compact storage.
