Big Castle Nut Removed

[Tim in New York]

Talked to my auto mechanic who also is a farmer and does ag work. He had me bring the Woods gearbox down to his shop and about 5 hits with his impact driver removed the large castle nut from the shaft. Thanks to everyone who responded with ideas - turned out to be the simplest one that worked. I did take the pto shafts in case we had to use those to keep the shaft from turning, but that was not an issue.

Now if I can get the pulley off and get to the oil seal......
