What is the Life Expectancy of a Husqvarna Riding Mower?

Husqvarna is a Swedish company that has been around since 1689, so they know a thing or two about manufacturing durable products. Their riding mowers are no exception and have an impressive life expectancy. With proper care and maintenance, a Husqvarna riding mower can last up to 10 years or more.

Of course, the life expectancy of any product depends on how it is used and cared for. If you neglect your mower and don’t perform regular maintenance, it will not last nearly as long as one that is well-cared for. The key to prolonging the life of your Husqvarna riding mower (or any lawnmower for that matter) is to keep it clean and sharp.

Here are some tips for cleaning and maintaining your Husqvarna riding mower: 1) Clean the underside of the deck after each use. This will prevent grass clippings from building up and rusting the deck.

2) Sharpen the blades at least once per season. dull blades tear grass rather than cut it cleanly, which stresses the grass and makes it more susceptible to disease. Sharp blades also make for a better cut, which means your lawn will look nicer longer.

3) Change the oil regularly – at least once per year or every 50 hours of use, whichever comes first. Fresh oil helps keep all of the engine’s moving parts lubricated and running smoothly. Over time, oil breaks down and becomes less effective at doing its job.

Old oil can also cause build-up and sludge formation in the engine, which can lead to serious problems down the road. So don’t forget to change that oil!

Why Does My Husqvarna Riding Mower Shut off When I Engage the Blades?

If you’re experiencing this issue with your Husqvarna riding mower, it’s likely due to a problem with the mower’s safety switch. This switch is designed to shut off the engine and blades when someone steps on the platform or if the platform is raised. If the switch is faulty, it can cause the engine to shut off when you engage the blades.

To troubleshoot this problem, start by checking the safety switch for any damage or debris that could be causing it to malfunction. If everything looks fine with the switch, then you’ll need to check the wiring going to it from the ignition key. Make sure all connections are tight and there are no loose wires.

If you’re still having trouble, it’s best to take your mower to a qualified repair shop for further diagnosis and repairs.
