Does engine crank (starter engages) or no crank when you turn key to start?

If no crank, what is the battery voltage?

Engine crank requires the following;

Brake ON
PTO OFF
Ignition switch to start position.

The seat occupied switch energizes the operator presence relay. This relay allows power to the PTO clutch from the PTO switch only when energized (operator in seat).

A simple test

1.PTO switch OFF
2.Ignition switch to ON position.
3.Engine not runnjng
4.Operator in seat

Pull PTO switch. You should hear the the clutch engage with a notable pop. Then turn off PTO and it will make another pop or clunk when it disengages.

Similarly with PTO engaged, if you rise from the seat it should disengage.


Also a failed charging system may allow the engine to start and run but not provide enough current to properly engage the electric PTO clutch. With engine running check battery voltage is greater than 13VDC.

An engine needs three things Fuel Compression A spark at the right time The battery is only needed to turn it over. New spark plugs properly gapped is good. A fuse only needs replacing if it has blown, and first, you must find out why it blew. If it 'rotated', then it did 'turn over', you mean it didn't start. Did it spark though? Remove the plugs and hold them connected against a solid earthed part of the engine. Turn the engine over, do you see a nice fat blue spark? I think you probably need professional service. ..

Check the leftside manual transport bypass lever has not somehow engaged. Compare it to the right side.The two transaxles are driven by the same belt so extremely unlikely it's a belt problem.Look for any signs of fluid leaking from the left transaxle shaft seal. If the seal has been leaking then it may be low on fluid. The transaxles are considered maintenance free so there are no instructions from Husqvarna for adding fluid but it can be done. However, if the shaft seal is leaking it will need replaced.See operators manual regarding bypass levers (rods).https://www.manualslib.com/manual/74128/Husqvarna-115-127127-Ir.html

No, check that the two fuel lines are not switched and fuel purge is working.

Easy way to test; Identify which line has the filter and disconnect the other (fuel return) at the carburetor. Then press purge bulb several times. Fuel should spurt out the fuel return port at the carb.

If no fuel spurt, move fuel line (with filter) to the other carb fuel port and repeat test. If still no fuel then purge is not working... either fuel not delivered from tank or carburetor is blocked or bad diaphragm or other.

Question edited for clarity to what I THINK you meant to say. I presume you mean a Husqvarna, you missed out the word 'belt', so I guessed it :>D I moved from the Hewlett Packard Computers Category to Husqvarna Riding Mower. The manual will always give you the belt routing diagram. There are videos as well. https://www.google.com/search?q=Husqvarna+Platinum+Series+LE+belt+routing
