Good to know... I've pretty much given up on trying to get that wheel off for now. I've been making some progress in figuring out why the mower is so hard to shift from forward to reverse and it seems to be connected to the adjustment for the brakes behind the right rear tire. I can make that adjustment without removing the wheel, although it would be easier with the wheel off.Regarding whacking the backside of a rim with a hammer, angle iron, or whatever to break it loose from the hub, I did that one time, and instead of the rim breaking loose, the retaining ring on the tip of the axle rod in the gear inside the transmission pulled out of its groove - so the entire axle rod-hub-wheel assembly slid out of the transmission.So I had to partially disassemble the transmission to retrieve the retainer ring and put a new retainer ring in.
Just an optical illusion.Been bugging me for a bit . From the 2 pics early in this thread , is the wheel further on the shaft than it is supposed to be ? Or is the flats for different models ?


I just had the same problem today. I jacked up the right side allowing the left rear tire to remain grounded.I've only had the mower for a couple of weeks so I don't know much about it. It started by having issues trying to shift from forward to reverse then progressed to where I had no brakes and it would creep forward when it was in gear. After looking at it, it looked like the issue was with the linkage that runs from the clutch/ brake peddle back to the transmission. Now I'm stuck because I can't get the rear tire off to see what's going on. I don't want to ruin a rim if I can help it. I might check with a local parts store to see if they have something that can loosen the rust. I've also seen where an 8" gear can be used to pry the wheel off but that involves taking all of the air out of the tire in order to get the gear puller on.
OK so, I'm still trying to figure this out. For now I've decided to work on getting the brakes and the drive belt tension figured out. After making an adjustment behind the right rear wheel, the mower seems to shift just fine now. The problem I had was I kept turning the adjustment nut clockwise until to get to the point that the belt tension was too tight. I noticed there is also an adjustment nut just like the one behind the rear wheel... can I make an adjustment up by the brake/ clutch shown in the picture? Also, thank you for sending the attachment showing how to check the gap on the brake pad adjustment with feeler gauge. If I can get this working properly, I'll move on to the much harder task of getting that rear tire off but for now it's fine the way it is unless I have to fix a flat tire at some point.Just an optical illusion.
Here is one here. It is suppose to be flush.

The OP problem is all this rust highlighted in this image and likely it worst than it looks.

You got it. That why I suggested Muriatic Acid with soaking cup as a last resort. Even that has to fight the penetrating oils. Its is about the only thing that dissolve rust as it penetrate and does minor to the good parts; unless it is aluminum then it destroys it. Just have to do it outside with a breeze.Funny how the acetone and Kroil did the worst.
Unless there is some void that allows the miracle juice to penetrate the threads, no spray on Earth will help. A nut and stud rusted over lacks these voids.
Saying that, I still fog it down usually waiting a couple weeks to allow the "wonder spray of the week" working time.
