Just be aware the axle is only retained in the transaxle by a snap ring--so any heavy handed hammer blows to the back side of the rim might end up making the axle come right out,and now the snap ring is floating somewhere inside the case..
Every year I usually see a lawn tractor tire,rim with its back side bashed in,and axle in the metal pile at the dump..
Sometimes the rest of the transaxle is sitting nearby too..
I have had many rims refuse to budge,had to use cutting torches or a sawsall to cut them off,and the axle seals usually get destroyed in the process..
Pullers sometimes work,but most of the time they just bend the rims before they pull free..
Worst rims to get off were the ones that had a roll pin driven thru the rim hub and axle shaft..those were on old sit down mowers with chain driven rear axles..most of them I had to destroy to get off..
I have resorted to tack welding a nut to the rim ,then screw a bolt in it and tighten it,so it pushes against the axle shaft--this will usually pull the rim off..if your careful you can grind the weld off and be able to use the rim again..
Thanks for the reply. I thought I'd better stop before I broke something, like the snap ring you mentioned, or bent the wheel. As mentioned above, I've used less force to break truck wheels loose that had rust welded themselves to the hub so it was definitely time to stop.
What I don't understand is why one rear slid right off and the other side was stuck. Both front wheels came right off this same tractor. I've never had this happen on my 180 and I've had wheels off and on a number of times. As Mark mentioned above, he had the same thing happen on the same "drive" side.
Did you ever figure out what had seized the wheels in place when you tore into them?
I had the FSM for this series of mower on an old laptop and just dug that out and so far see nothing mentioned about a difference in the rear wheel on that side for the 185 hydro versus the 180 gear drive.
Wonder if it's the heat from the hydro heating the axle shaft and creating some sort of bond between the wheel and the axle shaft over time, or something of that nature.
As mentioned, I'll probably just leave the wheels on there versus bend or break something now that I know it's not uncommon to have this happen. I don't have a welder else I'd try the trick with the nut.
