Mulching blades for 60in deck

[hillsandtrees]

I have a BX2671 with the RCK60D-26BX drive-over deck. It uses 3 K5371-9904 blades. Along the way, I have mowed a couple of stumps and one or two rocks. Today, while sharpening the blades I decided that they need replacement.

I would like to get a set of mulching blades to reduce the windrows I seem to create anytime the grass is a bit taller. I understand that the Gator G5 and G6 blades are a good replacement. The G6 is a lot heavier and I rather not increase the weight I have to speed up with the PTO clutch, so I am planning to stick with the lighter G5 blades. The lookup tools on the Oregon and various vendor sites don't really tell me which blade represents the replacement. From what I can put together, I need a 20-9/16IN blade with a 7/8th in hole. Does anyone know the Oregon part number for a G5 blade to replace the OEM ?

Get the G6.

The stock Oregon OEM replacement blades are 3.4lbs and the average G6 is something like 3.8lbs. Not enough to worry about. I got the G6 on my BX (54P deck) and there was no difference at all in clutch engagement vs stock. They are very good blades.

That said as far as a direct replacement, I dont see any Gators available at all for that machine. There are G6's available for Deeres that are a very similar size (7/8 bore, 20 1/2"L) but I dont want to say theyll work for sure. I suggest searching TBN, the 60 is pretty common, or even better calling oregon to get their recommendation . I understand they are pretty good to talk to. At one time I think there were even guys getting bushings made up to adapt the 1.xx" bore from the larger G6 Kubota blades down to 7/8 to work with the smaller spindles but I dont remember what became of that.
