Blade Speed
I have a Cub 2518, with a 48" deck that I have had for about 15 years. I am now having trouble with the speed of the blades. It does not throw the clippings like it use to, and leaves some grass uncut. I can hear the blades seeming to speed up and slow down. It just started doing this. The blades were replaced last season. I noticed the problem on my first cut of this season, so I sharpened the blades, and greased everything. I did notice 2 of the idler pulleys a little noisy so I replaced them, and both belts. Still no change. Any ideas? The PTO was replaced about 4 years ago. I am stumped. The blades seem to spin freely. Do you think it could be blade shafts? They are original.
