There are a number of reasons why you may need to remove the engine from your Husqvarna ride on mower – perhaps you want to rebuild it for improved performance or perhaps it has broken down and requires some attention. No matter the reason, it is important to keep in mind that removing the engine is much harder than it appears, as there are a variety of connections.
Step 1: Follow the fuel hose from the base of the petrol tank to the carburetor on the side of the engine. The hose should be clamped to the carburetor; squeeze this clamp with a pair of pliers and remove. Pull off the hose and direct into a bucket to drain the fuel.
Step 2: Find the throttle linkage; it should be located directly underneath the carburetor. A cable from the accelerator or throttle (depending on the drive of your mower) should be screwed into this spot; you can use a screwdriver to undo the cable.
Step 3: If you own an electric mower, you will need to find the starter; it should be on the side of the engine and will look similar to a soft drink can. Unscrew the red cable, which will be bolted to the side of the starter, using a wrench. This will prevent the mower from being accidentally turned on.
Step 4: Place a wrench on top of the bolts holding the bottom of the engine to the mower's frame. This will prevent the bolts from spinning when you remove the nuts, which are located underneath the frame. Lean the engine forward and slip the belt off the pulley on the crankshaft.
You should now be able to pick the engine up and remove it completely from the ride on mower frame (you may need a helper to do this). If you meet any resistance, you have not undone all of the nuts holding it to the frame. Whilst it is possible to contact your local Husqvarna dealer to do all of this for you, it will cost you a few hundred dollars and is something that you can easily do yourself.
