Troy Bilt 33" walk behind mower blades won't turn on.

Mine works,great,take bag off and it will mulch it and look like it's being bagged up.Is your grass knee high?Do you have it low enough?Here's your manual,read the part on grass catcher and see if your doing something wrong,make sure grass door is open.Check your blade to make sure they didn't put it on upside down.The cut part should be facing out. http://pdf.lowes.com/operatingguides/043033566280_oper.pdf

remove the center bolt from under the machine put a block of wood against the blade to hold it from turning on you

All riding mowers have a seat safety, blade engage safety and a brake clutch safety, some mowers have a reverse mowing safety. Seat under the seat, blade and brake you will have to check the linkages underneath, and if there is a reverse mowing one I have seen them near the shifter handle right under the fender.

I think you should go to your local dealer. They will be able to pull up the info you need and they may even print up for you a picture of the way the belt is installed. GOOD LUCK.

You can check your manual but i would use SAE 30, if in doubt call your Troy Bilt dealer

Check the voltage to the solenoid when the key is turned to start, it should be 8-12 volts. IF the voltage is low clean all electrical connections.

look up on the internet the make and model of your mower and look under diagrams
