The leaves are changing and starting to drop, signaling the end of the mowing season. While you might have a few more tasks in store for your lawn mower (like picking up all those leaves), it's time to start thinking about preparing it for storage over the winter.
In this article we're going to discuss all the steps to properly winterize your zero turn mower. It's not the most exciting task, but it will help to ensure your mower is ready to go as soon as spring rolls around.
This is a crucial step to ensuring there's no rust or erosion on the frame and working parts of your mower.
Built-up debris from the mowing season can wreak havoc in the nooks and crannies of your mower over the course of months. This can weaken the frame and other important components.
A thorough cleaning should include all of the following:
The first step in prepping the engine for the winter is to change the oil. This prevents any buildup in the oil from forming deposits within the oil pan or the engine itself. It's also one less thing you'll need to do when getting your mower ready in the spring.
Many zero turn riding lawn mowers utilize a hydraulic system for steering. Most recommend that you change this fluid every 300 hours or so. It's not absolutely mandatory to change this fluid for winterization, but it does ensure that you'll be starting the mowing season with all your bases covered.
Follow the manufacturers instructions for properly draining and replacing the hydraulic fluid in your mower.
Next you'll need to take care of all the gas left in the engine. This keeps the fuel from getting gummy or eroding the internal components of the engines.
There are a couple of choices here. You can either drain the fuel completely or fill the tank with fuel combined with a fuel stabilizer.
Though it's not our favorite method, draining the fuel costs nothing. The easiest way to drain the fuel is to just allow the mower to run until it completely runs out of gas. You can help it along by siphoning fuel from the tank back into a storage container. While this method is OK, it can still leave small amounts of fuel in the engine.
Our preferred method is to fill the tank with combination of fuel and stabilizer. Here's what you do.
Before stowing your mower make sure to either disconnect or remove the battery. If you're storing the mower in a shed it might be easier to remove it entirely so you can charge it every couple months.
This helps to extend the life of the battery and ensure quick starts. Another option is to just start the mower every couple of months and let it run for 10 minutes or so.
To disconnect the battery follow these steps:
You can also take this time to clean the terminals if they've become corroded. Here's an excellent article detailing the steps.
Keeping your mower dry is a great way to extend it's life. Whether you store it in a shed, barn, or in your garage during the winter season cover it with a tarp. This will keep dust and debris from building up on the mower.
While performing this type of maintenance might seem tedious it can help to extend the life of your mower. Plus, when spring rolls around you'll be ready to start mowing in no time.
