Small Engines (Lawn Mowers, etc.): 1996 john deere lx172 riding lawnmower, test light, clutches


Question
I need help on how to fix a problem? How can I get my blades to engage when I pull the knob? All I get is nothing, sometimes it engages but has no power at all, can you help me?

Answer
This a pretty vague question. I need a lot more info.
Do you have a 12 volt test light.
If not go to the local parts store and then I can help you.
No mater what if you don't have a test light all we can do is guess.
Your problem could be anything from a seized idler on the deck, to failed PTO clutch.
If you don't want to buy a test light and you want my first guess buy a pto switch Deere part number am118802 24.50 list.
Unfortunately LX172 pto clutches are just now starting to fail #am122969 105.00 list price.
