I have recently noticed a whining noise coming from the rear end of my L111 mower. It goes away when I press the brake and the fan stops spinning. Is my transmission going bad?
Two things I would check. First is the a build up of debris on the top of the hydro unit which is contacting the fan. Second check the hydro fluid level.
The unit is sealed, no place to check or change fluid. I looked at it in the manual. There was no info in there on troubleshooting the drive either. Is there a bearing on the fan that can go bad? The fan is clear of debris. Thanks for the suggestions.
No idea, got it used this summer. Looks good though. That would probably be the cheapest place to start. Is there a way to attach a recording of the noise?
Just went to YouTube and listened to the video. I don't think it is a transmission problem. It sounds to me like the idler pulley on the belt tensioner is bad. You'll need a second body. Have someone sit on the seat (deck must be off) and have them depress the brake pedal while you look underneath to locate the tensioner pulley. After you have located it, have them hold the pedal down while you check the pulley. It should turn freely and there should be no wobble. Post what you find.
I pulled them off today an the smaller one definitely turns harder than the larger one. Called Prairieland JD here in Wichita, they have them both. I will pick them up tomorrow and put them I and let you all know. Thanks again, Rivets!
I would change the drive belt at the same time. May have been damaged by a bad pulley. Mig,hr just as well change it while your under there. Just a suggestion.
