[QUOTE="DiamondSCattleCo, post: 689318, member: 2862"] In addition to what others have mentioned, its time to check the drive system for t slippage. I'm not familiar with the 488, but does it use belts anywhere in the drive? If so, check them for tightness. Also check all the bearings with a prybar. Buildup on the knife isn't necessarily poor guards or knife. Also check your reel tines to ensure they've not slipped or are set properly. Especially check the end tines. Buildup often starts at one end or the other and works its way across the cutterbar. Check your auger to stripper bar clearance. This needs to be tight. I run no more than 1/8 inch away from the stripper bars. My MacDon 16 foot had buildup issues, much the same as you're describing and it turned out to be a bad hydraulic pump. I'm back to cutting 3 ton/acre hay at 6 mph with absolutely no plugging issues. I replaced the knife and guards, checked all my settings, replaced a couple of suspect bearings before I finally checked the power unit. Wish I'd checked it first. On the disc mower side, I don't think you'll be happy moving from a conditioning machine to a non-conditioning machine, especially if your windrows are heavy. Heavy windrows simply don't cure down unless they're crimped. Rod [/QUOTE]
