Are you a proud owner of a John Deere F725? This lawnmower is a workhorse, capable of tackling even the toughest mowing jobs. However, as with any piece of machinery, it’s not immune to problems. Have you ever encountered a problem with your John Deere F725, leaving you scratching your head in frustration?
Well, you’re not alone! In fact, many John Deere F725 owners have experienced similar issues. But fear not, in this blog post, we will explore the most common John Deere F725 problems and provide you with possible solutions to help you get back to mowing your lawn in no time!
So, let’s dive in and solve those pesky problems together!
Troubleshooting John Deere F725 Engine Issues
Have you ever had trouble with your John Deere F725 front mower during the rainy season when the grass grows like crazy? Trust me, I know the feeling – it can be frustrating when your machine starts up just fine, but as soon as you try to tackle even slightly longer grass, the engine starts to cycle down.
One possible culprit could be bad plugs or a loose plug wire.
To check this, try removing one of the plug wires with some insulated pliers while the machine is running. Listen carefully to the engine sound – if there’s no difference, it could mean that cylinder isn’t running.
If the mower stalls out completely, try the same test with the other wire, just in case you accidentally pulled the plug on the cylinder that was actually working.
To avoid this kind of problem in the first place, it’s a good idea to run your machine on both cylinders whenever possible.
Here’s why: if one cylinder isn’t firing, raw gas will just keep pumping in without getting burned. Not only is this bad for your machine, it’s also bad for the environment.
So, keep an ear out for any differences in engine sound and make sure you’re running on both cylinders to keep things running smoothly, even during the rainy season grass growth frenzy!
Solving John Deere F725 Deck Troubles: Why Does It Keep Coming Off?
have you ever experienced your John Deere F725 mower deck belt coming off and then, to add insult to injury, the nuts on the pulleys get loose and the blades end up falling off too?
I’ve been there, and let me tell you, it’s a frustrating problem to deal with.
One possible cause of this issue is that the spindle bearings may be shot, which can cause the sieves to wobble and chew up belts. Loose bolts on the sieves could also indicate a blade balance problem.
But fear not, because there are solutions! To start, it’s important to have a good understanding of the structure of your mower deck.
During a security check, make sure everything related to the belt is in good shape. If something is out of place or damaged, it may need to be replaced.
Speaking of replacements, you might also need to replace the belts themselves. Another trick to consider is routing the belt in such a way that the blades run backward, which can help loosen those pesky nuts. It might seem counterintuitive, but trust me, it can do the trick.
So, don’t let a loose belt and falling blades bring you down – with a little knowledge and some replacement parts, this is an easy fix
Hey there, when it comes to getting a good cut on your lawn with your John Deere F725, checking the deck pitch is key.
Trust me, I learned this the hard way after struggling with uneven and patchy cuts for way too long. So, before you try anything else, make sure you check that deck pitch!
Now, if you’re running a negative pitch, you’re not going to get the cut you want. Aim for a difference of 1/8 to 1/4 inch between the blade tips. And don’t just eyeball it based on the edges of the deck – you need to turn your blades so they’re facing straight forward to back, then measure the heights of the tips.
Keep in mind that different decks have different configurations, so you might need to do some research or trial and error to find what works best for your machine.
Oh, and another thing – get rid of those gators and try some foils instead. And when it comes to blades, avoid using double-blade combos until you’ve solved any blowout problems you’re experiencing.
Trust me, I made the mistake of trying those out too soon and it just made things worse.
So, take it from me and check that deck pitch before anything else!
Understanding Why Your John Deere F725 Mower Shuts Down
you might have experienced a problem where your mower starts acting like it’s starving for fuel after about 30 minutes of mowing. Trust me, I know the feeling!
So, here’s what might be going on: your mower could be vapor locking. Don’t worry, it’s a common issue. But to fix it, you need to keep the fuel cap loose the next time you mow and see if it runs longer. If it does, then your tank is not venting properly, and you either need a new cap or to unplug the vent hose.
If your mower still dies after 30 minutes, then you might have a blockage or some other restriction in your fuel system. Debris in the tank can block the inlet or it could be a plugged fuel line issue.
To avoid this, it’s important to keep the interface always clean so that there is no excessive grass, oil or grease buildup.
If you’ve ruled out any blockages or restrictions and your tank is venting properly, then run the mower until it starts to sputter, and then loosen the fuel cap. If the problem ceases, then it’s likely the vent in the cap.
I hope this helps you get your mower back in action! Don’t forget to take care of your equipment to avoid future issues.
Mower Is Not Starting
I recently had a neighbor share their problem with me about their F725 mower. They were having some trouble with it – apparently, it had just quit on them out of nowhere because it ran out of gas.
But even after they refilled the tank, the mower still wouldn’t start. To add to the frustration, the battery drained really quickly after trying to start it up.
I suggested that they check the fuel pump and filter flex, and it looked like there was suction coming from the fuel pump. However, the line to the tank wasn’t clogged, but it also wasn’t getting any gas.
After doing a bit of digging, we discovered that a clogged vent in the fuel cap can cause a vacuum in the tank, which can prevent the fuel from flowing properly.
Luckily, there’s an easy fix for this – all you have to do is loosen the fuel cap. If that doesn’t work, the next step is to remove the fuel line from the carb and make sure that fuel is flowing properly while cranking the engine. If you’re getting flow to the carb, then it might be time to do a carb rebuild.
It turns out that this could be a common issue with the F725 Kawasaki motor – apparently, the motor uses a plastic cam gear which can break over time.
So, if you’re experiencing similar problems, you may need to replace the gear as well as the water pump and oil pump gear.
To figure out whether this is the issue, you can remove the valve covers and see if the valves move when you crank over the engine. If they don’t, then you might have a bad cam and will need to do a rebuild.
You can also pull the fuel pump and see if the pin moves when cranking the motor – if not, then the cam isn’t doing its job.
If you do need to replace the cam gear, it’s important to use a steel gear instead of a plastic one. And if any plastic bits have found their way into the oil, you’ll also need to replace the water pump and gear, as well as the oil pump gear to make sure they’re not damaged too.
Something else to keep in mind – I’m not sure where the fuel line comes from in your tank, but this can make a difference when it comes to operating on inclines.
The steeper the incline, the more fuel you’ll need in the tank to make sure that there’s adequate fuel flow. So, if you have steep terrain to mow, you might want to try to fill up the tank first, and then move to more level ground after a short time of operating.
If it’s all sloped, you could even carry a can of fuel on the machine with you and top it off after a certain amount of operating time.
From Dull Blades to Perfect Cuts: Solving John Deere F725 Blade Issues
I’ve had some customers come to me with a problem where their F725 John Deere Lawn Mower engine would get killed when they engaged the blades. Here’s what I suggested to them:
First things first, look under the deck and make sure there’s nothing stuck between the deck housing and the tip of the blades, like twine, cord, or even a rock that’s keeping it from turning.
Next, make sure the seat safety feature is securely connected to the underside of the seat. If it is, then check for any broken or frayed wires in the wiring harness and reconnect and tape them.
Don’t assume that the clutch has anything to do with the problem, but do check for bad bearings in the clutch immediately. If you don’t replace them right away, you’ll end up having to buy a new clutch instead of repairing it.
To replace the clutch, start by removing the blade and blade adapter, then use a large vise-grip to remove the spring.
Remove the bolt holding the clutch arm, disconnect the cable from the top side of the machine, and remove the engine mounting bolts. Have someone pull the engine away from the frame while you slide the clutch off.
I remember one time I had a similar issue with my own lawn mower. I couldn’t figure out why the engine kept dying when I engaged the blades. I looked under the deck and found a piece of wire that had gotten wrapped around the blade shaft, keeping it from turning.
Once I removed it, the problem was solved! It just goes to show that sometimes the solution can be simple, and it’s always worth taking a closer look before diving into more complicated repairs.
