Taking care of your property can be rewarding but also frustrating. Every homeowner wants their property to be spectacular, and be the talk of the town. However, overgrown grass, littered gutters, accumulated dirt on the roof, and other things paint a terrible picture of your property.
The Husqvarna riding mower can help you take care of the lawn, but there are times when the blades won’t turn on.
If your Husqvarna riding mower blades don’t engage, you need to check the PTO switch, drive belts, frozen pulley and make sure the battery is charged. Moreover, you can also check to see if the blade clutch is working correctly, and the safety switch is off.
When you have a short time to take care of your grass, it can be annoying when you turn on your mower, and the blades on your mower don’t do anything. This problem can easily transform the easy job of a normal day into a spontaneous and unwarranted session of repair.
How to Troubleshoot the Blades
While there are many variables that may prevent the blades from spinning, bear in mind that although others are common to all forms of products, there are some elements that are exclusive to different manufacturers.
So, before you even try to fix everything by yourself, you need to take a second look at the manufacturer’s manual for tips and precautions under the “Troubleshooting” section. However, if you can’t find anything there, we have compiled a list of things that you can do in order to make the blades work again, and troubleshoot any issues with your lawnmower.
How Can I Fix My Husqvarna Riding Mower Blades?
While there are certain specific things for every manufacturer, here are some things that can help restart your Husqvarna Riding mower. Let’s take a look.
- Deck Belt
- Engine Belt
- PTO Clutch
- PTO Switch
- Idler Pulley
- Safety Switch
1. Take A Look at The Deck Belt
If your mower blades do not turn on or engage after clicking on the blade controls, this could be an indication that your deck belt can be damaged.
The deck is positioned right beneath the seat. The belt rotates the blades of the mowers and operates over an idler pulley mechanism. The precise deck belt design would differ on the mower model you are using and varies from manufacturer to manufacturer.
Place the mower on a flat surface to check the deck board, then lower the deck to its lowest setting possible. The first thing that you need to is clean any dirt or grass that could have built up over the deck of the mower.
Next, you need to detach any guards or covers that shield the network of deck belt. When you have access to the belt, check it for any signs of damage, harm, wear, and tear. If the belt is merely misplaced, you can mount it back on. However, in case of damage, you need to change the belt.
2. Check The Engine Belts
So, you checked the deck belt, and there was nothing wrong with it. The next move is to take a look at the engine belt of your Husqvarna riding mower. The engine drive belt on the deck of the mower is responsible for the system of controlled activation and disengagement of the mower’s blades.
The mower blades do not activate if the belt is stretched out, worn out, or damaged. Replacing the drive belt will rectify the problem. Often, the blades do not activate if the drive belt is not directed correctly and mounted. To ensure that the belt is correctly mounted, take a look at the diagram in the owner’s manual.
Check for Damage
This engine belt collects the energy generated by the crankshaft’s rotating motion and subsequently converts it to power the deck belt motion. The first thing you need to do is to remove the top surface covering. When the coverings have been removed, check for any signs of damage, harm, or wear on the engine belt.
The motor travels from the mowers motor to the deck belt, which attaches to a pulley in the deck belt network. Over time, these belt structures and systems can accumulate dirt, debris, and dust. This is why you need to be sure to remove all of the blockages or debris that could hinder the belt from spinning freely.
1. Check the PTO Clutch
Every Husqvarna riding mower comes with a Power Take-Off Clutch, also known as the PTO clutch. This clutch gives the operator the power to disconnect the engine from the blades manually. This energized clutch gives power to the drive belts to engage and rotate the blades.
If this PTO clutch is not getting enough power, the mower blades will not engage and turn on. You need to check whether the clutch solenoid is defective or the clutch is damaged or worn out. Once you have identified the problem, you can either opt for a new clutch or have a professional lawn mower repair specialist to fix it for you.
2. Check the PTO Switch
The next item that you need to check is the PTO switch. This PTO switch is responsible for providing power to the PTO clutch. If this is worn out or damaged, the PTO clutch will not get any power, and as a result, the blades won’t engage.
Turn on the PTO switch, and use a multimeter to check its consistency and power supply. If you notice any inconsistencies in the power supply, replace the PTO switch with a new one.
3. Check the Idler Pulley
The idler pulley of your mower adjusts the tension within the drive belt, and the drive belt turns the blades. If this pulley is frozen or stuck, it will not adjust the tension, and the blades won’t engage.
You can easily fix this by replacing or repairing a broken or frozen idler pulley, and the blades will start turning on again. You may differentiate an idler pulley from the bearings in its middle from other pulleys on the mower. The other types of pulleys are fastened to a single shaft.
4. Check the Safety Switch
Lastly, you need to check the safety switch on your Husqvarna riding mower. A poor protection mechanism will even stop the spinning of the mower blades.
Some lawn mowers are fitted with one or two safety switches, which are programmed to refrain the blades from spinning and engaging. So, you need to take a look and see if these switches are turned on or off.
Check the switches and also check the electrical connections inside these safety switches. Sometimes, the switches are turned off, but the electrical connections send out signals to the blades to stop working.
What is The Bottom Line Here?
If you have inspected everything, and you cannot find any problems, you need to call a professional riding mower repair specialist to assist you. No need to keep whacking at every belt to see if the blades will engage. It is not a remote control.
The tips mentioned above will help you do a preliminary inspection by yourself. If nothing else works, call a professional repairer and fix the blades.
