Hopefully, you squirt a bunch of penetrating oil, on top and bottom, while you wait for her to get home. (may help)

Also, don't forget your safety jack stands (when you start tugging on those wrenches) = we've had a couple farmers die, in the last 20 years, from lawn mowers falling on them.

Edit: Dad is really good about, using jack stands, when he cleans and scrapes the underside of his Dixie Chopper.

Well, Mark, if you see this,

 I just finished mowing with Dad's Dixie Chopper and when blowing it off and scraping the underside of deck; I noticed the idler was cocked and belt running uneven in pulley. Sure enough, bushing stuck to "shoulder bolt" and nut coming loose under deck.

The original "bolt hole" , in deck, for that shoulder bolt, doesn't look too bad, so just some new parts (bolt, bushing, nut, spring) should fix this one.

{Note: Bushing seized onto shoulder bolt, once removed, I tapped out bushing with seized bolt, together as a unit, from the "press-fit" of the idler arm.}

Question: If you got a new idler arm, Did it come with a grease fitting? (maybe an updated part or something) Thanks.

Thanks,

 I ordered parts yesterday, and the parts guy told me that there wasn't any update or grease zerq.

May have to modify the original bracket/bushing.
