Just got a used Buhler Y550r finish mower and can't get the blades off for sharpening. Are the bolts right hand or left hand thread? May put a little heat on them and let them soak. Ideas? Thanks
They should be right hand thread. Use impact wrench, a new mower will have thread lock sealant on them. The manual says it is good for about 5 blade removals and then reapply. The large washer under the blade bolt may have a curved surface on the side nearest the bolt head. If it does just make sure the flat side goes against the bladewhen you reinstall the blades.
Thanks for all the help! Impact wrench did the job! May have goofed up reinstalling the blades.Put antiseze on bolts not thread lock.
Wish I looked here before I finished up today.
