I have a 2006 JD 2305, which I have OCD about taking good care of it.
I keep the oil changed, I change the filters and grease everything the manual says to grease.
But, did you know that, there are grease fittings on your main driveshaft? I didn't?
A new driveshaft cost $751.00, ask me how I know this.
John Deere says they realized they left this out of the manual in 2010 and sent out flyers to "almost everyone". I didn't get one!
Check your driveshaft for grease fittings before it's too late.
