    • Well made and light weight while nicely powered and sized for the price.
Set name: 144cc-2-1
Super Easy Set Up with no tools required. Seems to be well made while being lighter than older mowers. It is easily manuverable with the nice wheels sizes especially the larger set on the back that make turns and uneven lawns less work to navigate. Includes the required engine old for use. It's winter here where I live currently so I could not mow with it yet but did run it and it started easily. Just add the oil that's included and your gasoline and 3 pulls later mine roar d to lift. Priced retail at $299 its already a great size deck and higher engine output option compared to others in the same dollar bracket. At the time of my purchase it was on sale for $197 which made it a very impressive multching or side discharge mower compared to any other options similarly priced. If you are looking for the best gas powered mulching mower for around $200 dollars save yourself the search time and shopping and take one of these home. I feel it's a fantastic machine for the money. ... show more

    • Broken parts and was assembled in correctly
Set name: 144cc-2-1
Lawnmower runs great. Only 2 issues. The first is the bolt to secure the handle to the frame is broken. The second one was, who ever assembled the wheels needs training. They put the height adjuster on upside down. Nowhere, on here, am I able to get these parts replaced.

    • No one from Senix Customer Support willing to help!
Set name: 144cc-2-1
Review Image by Mike Withrow
So when it was delivered the handle was bent. I contacted Senix customer support and was told to register the mower and then get in contact with Amazon for a solution. I zip tied it to make it work. (1 Strike) Then about 2 weeks ago as I was mowing it stopped. Wouldn’t start. I tried emailing Senix customer support again this time I got NO response. Not happy with your product however you don’t even seem to care enough to respond. (Strike 2) It’s an affordable lawn mower that mows good when it’s running. I just think I got the 1 out of a lot that has issues and have no one willing to make it right. I’m still in the batters box waiting on the pitch with 2 strikes. ... show more

    • Good value mower
Set name: 140cc
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

    • Very functional lawn mower
Set name: 144cc-2-1
A great lightweight lawn mower. Starts easily. I have been letting it run out all gas at end of use. This keeps the carburetor clean and helps it to start well.

    • Well worth the money
Set name: 144cc-2-1
This is an excellent mower. Mine arrived with a small defect, and I can't remember the last time I had a more positive experience with a company's customer service department. This is the first Senix product I have purchased, but within the near future, based on my experience with this one, I will be replacing other tools with Senix products. The same quality (with way better customer service) as the brand names people have always been loyal to, for a MUCH lower price. It's worth saying again, Senix is get my a return customer. ... show more
