      Q:Under the specifications tag, what is the acre specification for? Does the mower stop after mowing half an acre or do I need to empty the bag if I’m bagging? Please explain.

      Answer This Question

      A:  Hello Robb. The acreage listed under the specifications is a generic recommendation for what your personal acreage is. For example, this might be a good mower if you have an acre to mow. On the opposite side, you may want to search for a different mower if you have more than an acre to mow. Thank you for the question.

          Horrible so far.
          I bought this mower back in Dec of 23, to be prepared for mowing season of 24. I opened it up a few days ado, now 3/30/24. I assembled it, put oil in it, gas, the common stuff. I fired it up just to make sure it worked, but to my dismay it was leaking oil already within 2 minutes of being on. I turned it to discover what appears to be hairline fractures on the bottom of the motor, incredibly disappointed.

            Easy put together and start!!
            [This review was collected as part of a promotion.] I am a 74 year old woman and was able to put this mower together myself and it started on the 1st full. I am so happy about that!!

            Made of more plastic then they used to be.
            [This review was collected as part of a promotion.] I previously had a TB 110. Hands down the best push mower I ever had in my life. I moved to a new location and decided that I would sell that mower and get an electric mower. That was a mistake. Thankfully I was able to give that to my retired parents, which admittedly is a much easier lawn mower to push at that age and muscle strength status. The electric Ryobi 40 volt is good for flat grassy lawns but no good for pine straw and oak leaves or magnolia leaves. I purchased this mower and at first glance it's pretty much like the TB110. However, I can see several shortcuts mainly involving plastic. And this "check the oil don't change the oil" is the silliest thing I think I've ever heard of. Of course I will maintain an inline fuel filter with shut off valve with good clean non-ethanol gas with the proper enzymes and additives. I expect this one to last as long as the other one would have. But like I said, there are some pieces that are more plastic than metal this time around. Even the side discharge attachment does not have the clips on it to attach to the handles. But other than that, I think I'm going to be very satisfied with this mower.

            Nice mower. Side shoot pops off with slightest bump. Other than that I'm happy with it.

            Works well, although the rear bagger needs a redesign. Much of the clippings don’t make it to the bagger.

            Poor Support
            Not much power. Wheels wouldn’t raise without taking wheels off. Bought online in early March could not find receipt online or at Home Depot. Didn’t use for first couple months do to weather. Home Depot would not take it back Toro would not do warranty work without receipt. Would not start found flywheel was cracked had numerous smaller cracks. Bought a new one put it on run well now. Still difficult to raise and lower back wheels. Probably just a defective but poor customer support Home Depot

              Mower is not self propelled which I made me hesitant to buy. It was a good decision and handles the job well. The shoot detaches easily and takes getting used to. Used mower 4 cuttings and I am pleased with the performance.
