This time, we ordered new blades, the old ones were original equipment and were done. Since I can't roll around on the concrete, we decided to do it the easy way. We put the mower on the concrete pad and dropped it. Took off the drive shaft, and then rolled it forward onto the attachment points so it was standing vertical and tied it off so it was stable and couldn't fall. Then I could sit in the chair and work. Soaked the bolts in WD40 and let them sit for a half hour.
Half inch breaker bar and Bam... off came the old blades. New blades went right on. 55 foot pounds of torque per spec, and we were golden.
While we had the mower handy to the shop, greased all the fittings, greased the shafts for the pto on the tractor and the mower, and the U-joints on the drive shaft. All in all, about 90 minutes work. Cut like a dream.
Gimpy all Grumpy can still git some things done.
