Riding Lawn Mower Blades Won't Engage
Taking care of the lawn is made easy with a riding lawnmower. Like every other machine, you don’t expect it not to develop faults. From the belt to the battery, things can cause the riding lawn mower blades not to engage. When these problems arise, our technical expert advises that you should do the following.
Refer to Manual from Manufacturer
Before carrying out any replacement, you should inspect the belt first. The configuration depends on the model and manufacturer, but most lawn mowers have the same design. Reduce the deck to its lowest setting and check out if it’s damaged or has accumulated grasses.
The belt must be inspected at least every six months. This way, you won’t be surprised and frustrated when you want to take care of the lawn.
Replace Belt, Cables, or Clutches
If you discover that the belt is damaged after inspecting it, you should correct the problem by replacing it. If it’s loose or too stretched, you should replace it as well.
If the blades don’t still work even after replacing the belt, you should check the blade cable. The cable is made up of metal with cast metal ends, a plastic sheath, and a bracket. If the metal ends are damaged or the cable gets kinked, you should replace it immediately.
You can do the same to the clutches if you find any of the parts damaged. Lawnmowers have clutches that shut off the blades while the engine is running. This part can wear out over time, and when they do, they won’t be able to power the blades.
It’s necessary that you inspect them for proper diagnosis. Disassemble the mower to monitor the clutch better.
If any of the parts that make up the clutches develops a fault, the blades won’t engage. It means you should replace them.
The pulley could be another reason why the riding lawn mower blades won’t engage. The mower’s pulley controls the tension in the drive belt, which in turn turns the blades. If the pulley freezes and doesn’t rotate, the blades won’t engage.
Check Power Source/ Battery
Lawnmowers use the PTO (Power Takeoff) clutch mechanism to engage the blades. PTOs are either manually operated or electric. Batteries run the electric PTOs.
If the battery has a weak charge or is dead, it won’t power the blades. So, if the blades refuse to engage after powering it on, ensure that you check the battery. You must fully charge the battery, and if it’s faulty, you should replace it with a new one.
Tips and Reminders
Here are some tips and reminders you must have at the back of your mind when engaging the mower blades.
Why won't my riding mower blades engage?
How do you engage the blades on a riding lawn mower?
To engage the blades on a riding lawn mower that’s manually operated, turn the key clockwise to power it on, increase the throttle to half speed, and allow the engine to warm up for two minutes.
Then, lower the mower to the preferred cutting height. Push the lever to the right of the steering to engage the blades.
It’s the same if you want to engage a lawnmower with electric blades, except that you don’t have to push the lever to the right of the steering to engage the blades. Just pull up on the yellow Power Takeoff switch to the right of steering.
