    • Makes Mowing Enjoyable
Color: Black
Purchased at the end of summer 2023 because our mower broke. This arrived in a nice colored box in a couple of days. EZ assembly. Took about 5 minutes. Comes with the engine oil needed. Simply add gas and on the 1st pull, it started right up. Very easy to adjust the wheel heights and the larger rear wheels really make this mower easy to handle and maneuver. This has multiple catch features. Either in the bag, out the side and the cross-cutting mulching works GREAT! Actually looking forward now to the spring so I can start mowing again. Such a great value too compared to some of the other bigger name brands out there. The actual engine is the EXACT same one found on many of them but this is half the price. HIGHLY RECOMMEND. ... show more

    • Good value mower
Color: Black
Review Image by CFM
Good light duty lawn mower for the price. Came with the required oil and was simple to assemble the handle into position. They have knobs so no tools are required. Having the option of side discharge, mulch, or bag is a nice feature. Poured in the oil and some gas and fired right up and cut my yard without any problems. It has a decent quality Briggs and Stratton motor that had plenty of power to cut my St. Augustine sod lawn without struggling. The only issue I had was one of the adjustment handles for the wheels was bent in shipping or packaging and I had to remove the wheel to get the adjustment bar bent back into shape. For me this wasn’t difficult, but could be a problem for someone without the tools, etc to complete the repair. Update: After sitting for the winter a couple of months, the mower started first pull and ran fine. I use Sta-Bil fuel treatment in the gas. Without fuel treatment the ethanol will destroy the carburetor. ... show more

    • terrible customer support/warranty support
Color: Black
Review Image by William Sullenger
Customer support is really, really bad. The frame for the grass catcher had a faulty weld and it broke on my first use. I immediately filled out the support request form on the Senix website providing all warranty information. I also emailed them pictures of the faulty weld and described the situation and provided a picture of my Amazon purchase. I purchased this mower over two months ago and after 10 attempts at getting this resolved, they are asking for all the proof/documentation again. Weeks can pass before I get a response, if I get a response at all. I'm beyond frustrated. ... show more

It’s a good one and cut quality is really good. Perfect gor small backyards. Speed is fine but a bit of noisy. We switched from an electric one and this one is definitely easier to use.
