are you telling me you have a diff lock on Your john deere? How do I get one on my 2005 GT 245 20 hp hydrostatic? havent had any info from the local JD back yard mecenics or dealer yet It sure does need it. merc 49.thanks
The GT series never came with diff lock.
The GX series did.
If you want diff lock real bad you can look on Ebay for the rear end out of a GX series machine. (yrs 2004-2006)
The rear end in your GT 245 is the same model as the GX 255's rear end but is a different version.
If you can't find a rear end with diff lock you could try different tires or tire chains.
I have been running these tires with very good luck.
You could also try adding wheel weights. 55 pounds on each wheel will add a lot of traction.
Hope this helps.
