2010 Gravely Zt 42 Xl Zero Turn Mower Kawasaki ()

I have a Gravely 52″ cut 0 turn mower, it has a 21 HP Kawasaki engine, It develop a problem recently in that whenever the blade is engage the engine cuts out and he driver is still sitting in the seat. what could be the cause of this?I notice that the fuel filter is not filling up!
Experienced gardeners share their insights in answering this question :
It sounds like the seat safety switch is the problem. Tilt up the seat and make sure the plug to the seat switch isn’t loose or off completely, and that the switch is firmly mounted. If everything seems ok, remove the switch and test it with a multimeter. The circuit between the switch terminals should close when you press in the button. If not, replace it. Good luck!

If the engine dies when the blades engage, it could be the result of a damaged safety switch. The first step in assessing the safety switch is to make sure it is plugged in securely. The switch is located underneath the seat, and you may have to remove the seat to reach it.
Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try.
This is most likely a safety switch issue. Usually the seat safety switch will cause this problem. The mower dies because it thinks nobody is sitting in the seat, and shuts off for safety reasons.
What`s happening? This is a normal function of the seat safety switch. With the blades engaged, weight from the operator allows the seat safety switch to keep the engine running.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
If the mowing deck is engaged and the unit is in reverse, the mower will shut down as part of a safety feature.
If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.
You are mowing your lawn too quickly.

Uncut lines can arise when you are mowing too quickly, since the engine is forced to work harder, maximizing its own throttle. Engine problems can be the root of several gardening issues. The solution is just as simple as the problem itself: Go slower! Take your time.

If your riding lawn mower engine dies when you release the brake, there`s a good chance the mower`s seat switch is broken or unplugged. The seat switch stops the engine when it doesn`t detect an operator sitting on the seat to prevent the mower from moving without a driver.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

Engine dies if i engage blades or take my foot off the brake
ANSWER : You likely need to replace the brake switch,the seat switch can also cause the same problem.Most likely problem is the seat switch,i would try that first.The pto or the reverse switch can cause a shut down but not until you try to mow,seat switch is the most suspect.

When you engage the blade the motor dies. Why
ANSWER : Most likely it is a bad safety switch under the seat. Please vote yes if this is helpful.

Serviced my riding lawnmower runs great. but when I put in drive it dies out. Also when I engage blades it dies out. No problems last summer. It won,t stay running when I do these two steps
ANSWER : Probably the seat safety switch. If it’s not activated (from your weight on the seat) the engine is killed when you put it in gear, or engage the blades. Lift up the seat and check the switch – wires on tight? switch tightly mounted? You can take the switch out and tape it in the pushed-in position to test things. If that doesn’t let the mower run, the switch itself is probably bad, but it could also be a connector that knocked loose when you serviced the mower. Check wires and connectors. Good luck!

I started the mower but the blades will not turn. I shut it off and was able to manually turn the blades by hand. I also was able to turn the belt wheel under the engine and have it turn the blades. With it running and me on the seat, they don’t turn. With it running; brake engaged; and I pull the mower switch to engage them, the mower wants to die. Two questions: Is there a swtich on the seat to insure the blades can not turn while no one is on the seat? Is there a key between the belt wheel and the PTO shaft that needs to be replaced? Thank you.
ANSWER : Most all riders have a safety seat switch now and they do malfuction alot. They are under the seat and are ez to replace most of the time. First look for a wire that is grounding due to rubbing a sharp object. That can be fixed with black tape

Good luck!!!

When I engage the clutch, the engine dies. The baldes turn freely, so it looks like and electrical problem. Is there a safety device that would kill the engine when the clutch is engaged?
ANSWER : All modern riding mowers now days have several safety switches and or relays/micro switches. Some are simple blade switches that make or break contact depending on the position of a lever. There is a contactor under the seat that will kill the engine if you fall off(you have to sit on it for it for the engine to keep running). There is one that kills the engine if you put the mower in reverse with the blades engaged. And there is a contactor that senses wether the mower blades are in fact engaged or not. It may be awkward but you can look at all the mechanisms and find where the different contactors are and move the levers back and forth to see if they aren’t dirty, bent, or a securement screw is loose or missing. It is also possible that one of the wires are broken or have come off of its connection point. Once you inspect them you should be able to determine the next course of action. These are not hard to fix although they can be difficult to get to. If it has a micro-switch at one of these locations you may need to test it with a continuity meter to determine if it is good or not.

When engaging blades engine dies after mowing over 2in sawn off tree stump
ANSWER : Take deck belt of and check that blades stiil turn by hand most likley bent or broken

When I hold the bar down that engages the blade it will not cut?
ANSWER : Is the blade sharp?

I have a Craftsman FS5500 48″ lawn mower. The PTO makes a noise (squeak) for a second when I pull up on the red blade engage knob. The blades do not engage. PTO does not turn. When I push the red button down to disengage there is a brief squeak from the PTO.

It worked well the past month then a little problem 2 weeks ago. It seemed to disengage after mowing a while. Then after sitting for 15 minutes the blades would engage. I used it earlier this week and the PTO won’t turn at all.

Just purchased from the last and original owner a month ago. He said the oil would need to be changed this summer. Could that be part of the problem? Engine runs great!

Also, I need an owners manual, not able to find from the previous owner.

Thanks

ANSWER : Hi,The problem is probably in the button that you pull and push to engaged and disengage the PTO… If you wiggle the button or try to pull it slowly, you may find a spot where it will work. But the button has gone bad and will need to be replaced.If you are comfortable with wiring, you could jumper the wires and getting it working, but it would be a very temporary and possibly dangerous fix…
