Design and Build Quality

No products found.

As you would expect from Husqvarna the build quality is of a high standard. Every aspect of the machine has been designed for comfortable and effective use. It has a solid and durable steel deck. The single blade is 21-inches.

The soft-grip handles are over-molded to keep you comfortable for longer. This will reduce fatigue as you operate the lawn mower.

It has been designed to be compact and easy to store. Once the handles are folded back it will fit most sheds or garages easily.

The wheels have also been well designed and are effective and smooth.

The Husqvarna LC121P is built to perform effectively and with ease. The Briggs & Stratton 163cc engine gives it plenty of power and the ReadyStart ignition allows you to get it up and running in no time.

The 11 inch rear wheels allow you to glide effortlessly even on rough parts of the yard and they are made even smoother by the sealed ball bearings. This and the 21-inch blade make this a formidable option for any medium to large yard. You will be able to cut the grass quickly and effectively with minimal hassle or effort.

The 3-in-1 side discharge, rear discharge, and mulching features are useful as is the generous 1.9-bushel grass bag. This will mean fewer trips to empty the bag for faster results.

The gas tank will give you approximately 50 minutes of use depending on the condition and height of the grass. This is generally enough for most medium to large yards, although in some cases you will need to top up to complete the job. This is relatively easy to do once you have the hang of it.

The lawn mower has good safety features and the operator presence control bar will automatically stop the engine when released. It also has a deflector at the rear to stop stones or debris shooting back and striking the user.

Minimal assembly is required and is pretty straightforward. The Husqvarna LC121P is comfortable and user-friendly.

    This mower has critical plastic parts and needs repair after approximately 1 year’s use. The repair parts are also equally as poorly made. This company has dropped it’s quality dramatically over the years.

  2. Hi i need a gas cap for my husqvarna lc 121p ..motor biggs statton …i need to have p/n for order nee one thx

  3. While this mower runs and starts very well the side discharge chute makes this mower one of the worst I have ever had . It plugs continually and in less than a year the door that holds the chute has collapsed it and broken off the plastic fingers that hold it there. It would appear there was no real world testing of this part.

    1. Hi Randy

      Thanks for sharing your experience of this Husqvarna mower. This is very much unlike Husqvarna as normally the quality of the components are excellent.

      You are right, the real test of quality is time.

      Thanks again.
