Went to start my tractor and found battery is dead. Jumped the battery and tractor started. I am going to replace battery. Question: My deck did not lower. Is this because the battery was not charged and very week or another problem

YOU NEED TO REPLACE THE SOLENOID IT IS SHORTING OUT AS TO THE GAUGE THEY WILL NEVER MOVE AS THE GENERATOR CHARGES ONLY WHEN THE BATTERY HITS 9 VOLTS THEN IT ACTIVATES TO CHARGE BACK TO 12 VOLTS BUT IN SMALL INCREMENTS

Check your charging system as purplewg recommends. Remove the battery, bring it to full charge and take it to an automotive store or battery shop and have them load test the battery to see if it will hold the full charge. Most places will do this free of charge....if your battery is more than two years old it probably needs to be replaced anyway....Autozone carries a really good tractor type battery for about 35 to 40 bucks that has a lot more amp hours power than most batteries you can buy...if you have to replace the battery get one of these....you'll be glad you did !!! I bought one for my personal mower which sees a LOT of use, and it's been in my mower for three and a half years and going strong...Hope this helps...;-D

A wiring diagram and a test light are needed. If you don't have the wiring diagram, use a test light, start at the clutch and work your way back checking for current at each switch/connector. It maybe the ignition switch, there should be one terminal on it that feeds 12v to the clutch curcuit.

could be your ignition switch but thats the best way to find out where its not getting power to.
