    The engine runs great...starts on whim....I can run around the block all day with...just cant cut grass! As soon as I engage the PTO, the engine cuts off with a whoosh.

    Do you think anything is wrong with the PTO itself? Since the carbeurator isnt covered by the warranty, I was really hoping it was!...The dealer specificaaly told me that the carb is NOT covered.

Hello

After the Engine Stalls, Check the Plug for Fire. If No Fire then the Ign Module/Coil is BAd and Requires Replacing.
>>The Following is a Basic Instruction File I made for this. Any Input is Appreciated. I Usually Suggest you Check the Following in this Order for a Problem like yours. 1- Check the Gas Tank Cap and Ensure it is Venting the Tank. A Vacuum Builds in the Tank and the Gas Flow Stops or Slows (15 to 45 Minutes and if the Small Grainular Sand is in the Tank it can Take Several Days of Constant Running to Bring All the Sand Particales to the Tank Outlet Port) to a Point it Shuts Off the Engine. 2- Operate the Equipment Until it Quits (15min to 1hr). Then Immediately Check for Fire from the Plug. If the Plug is Firing, then 3- Check the Carburetor Solenoid. If the Carburetor Shut Off Solenoid has Current, then Remove the Carburetor Solenoid and Go to the Hardware Store. Purchase a Bolt of the Same Diameter and Threads. It Needs to be 3/4" Long. Put this Bolt in Place of the Solenoid. If this Corrects the Engine Problem, then Replace the Solenoid. ***NOTE: THIS IS FOR CHECKING THE SOLENOID ONLY I NEVER SUGGEST YOU OPERATE THE ENGINE WITH THE SOLENOID OUT OF THE CARBURETOR EXCEPT FOR TESTING PURPOSES*** Sometimes the Plunger is Moving, Just Not Far Enough to Allow the Gas to Enter the Jets. 4- Depending on the Model Mower, it can Also be the Pickup Tube in the Gas Tank. If No Fire, then Remove the Shut Off Wire from the Coil and Check for Fire. If Still No Fire, then the Ign Module or Coil is Bad. **Even if the Coil is New of Fairly New, it can Still be Bad.** On JD Mowers; Remove the Igniter/Module and the Coil and have the Local JD Dealer Test them.
Please, Do Not Hesitate, If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens,

After reverse, my cub cadet zero turn mower pto will not re engage the blades. sporadic up to the point of stopping altogether. is it the switch or clutch?


I would guess it is the switch. My Cub Cadet has a safety feature where the blades (PTO) stop when you hit reverse. There is an override where you turn the key back about a quarter turn or so and hit a button right above the key to make the blades run even in reverse. Therefore, I would guess the ignition switch is the problem but I can't be certain. Or it could be the electric switch that engages the PTO.

Cant get the switch to acctavate the mower deck on a cub cadet lawnmower


Check the fuse, tan/blue wire coming off ig switch or tan coming off PTO sw.
If it keeps blowing, check wire going to PTO unit for shorts or defective connection to PTO.

Pto will not disengage


first unplug the switch and see if it still operate then disconnect the spark plugs then turn the blades threw the discharge opening and see if the engine rotates when moving the blades this will tell you if the clutch is stuck then connect the spark plug wires back on and next to the engine base you will find a 2 wire connector that feeds the clutch power and ground unplug that connector and start the mower see if the blades turn this will tell you if you have a mechanical failure if it does not operate with the wires unplugged its a electrical

I have a cub cadet RZT 54 that was purchased in the spring of 2009. The mower cranks and runs fine but the blades will not engage. Have looked at electrical connections and everything looks fine.


Do you hear a "clunk" when you engage the PTO switch, but the blades don't turn? If so, then check the mower deck belt - is it properly threaded, and tensioned by the idler pulley? If there's absolutely no sound when you engage the PTO switch, the problem is likely electrical (even though everything looks OK). The PTO switch, PTO clutch, and the reverse lockout switches (near the bottom of the fwd/reverse control arms) should be checked. I don't think there's a separate fuse for the PTO on your mower, but there may be a relay. Even though these parts and connections look OK, they can fail internally. Best bet is to get a multitester and check each of them with the ohmmeter function.

Chances are your blades are activated by a vacuum system. Often times that vacuum switch goes bad and has to be replaced.
