does anyone know if you can actually find bearings for the gear box on a 425 john deere lawn mower deck. The guys at john deere told me it was a throw away gear box b/c you cant get gears, and they want $780 for a new one?

Most bearings have a number stamped on them. Sometimes it's a little hard to read, but if you can get the old bearings out and find a number on them, any place that specializes in bearings and such should be able to supply what you need.

Check ebay if you have to buy the gear box.

Haven't had one apart in over 10 years, but they used to be rebuildable..

A good trick to know on these is that if you have one worn enough to not seal well, IE, keeps leaking past shaft seals, is that you can drain the oil and fill it with Deere cornhead grease.

Used that trick on several commercial mowers with the same gearbox, with great success.

the only way to tell is pull the part with the bad bearing, if its a spindle you should be able to buy a bearing, if you can see the number on the bearing a good auto parts store can get it, if they dont have it already most of these use a common bearing, if its on a idler wheel it may still be available but its going to be a lot harder to change, most are made by riviting 2 stamped halves togeather, with the bearing inbetween the halves, youll have to drill out or grind off the rivits taking great care not to damage the stamped steel pulley at all, replace the bearing, then using grade 8 bolts that are exactly the same diameter as the hole in the pulley and as short as possible, while allowing the nut to fully engauge the threads on the bolts [ use locknuts this is critical] put the 2 halves back togeather, keep in mind that if the old bearing has steel seals over the balls you must use the same style, plastic seals may melt from heat

The gearbox on the 54 inch deck is not serviced by JD. I have been able to get some of them repaired but usually the gears are shot in them when the bearing go out.
