Toro Zero turn

I had a flat tire on my Toro SS4235 lawn mower. When I took the tire off, one of the lug bolts was rattling around. After I got the tire off, I found the lug bolt was broke from the hub. Is there any way to take the hub off without buying a puller?

Welcome to the forums! Can the lug bolt not be removed independently by driving it out ? Can you post a picture or two showing the problem?

It is not the bolt that is the problem. It is the hub itself. The hub broke with the bolt in it. I need to replace the broken hub.

The Toro zero turn model number is 74624. It is a 2011 model. The hub has 4 bolts. That is what broke. It sheared off about the middle of where the bolt goes through the hub.

From the diagram, looks like the hub is held on to the splined shaft by just a single hex lock nut in the center, right? If it won't come off with some judicious pulling and tapping after removing the nut, then I'd say a puller is required to avoid any possible damage to the transaxle. You can borrow them from many car parts stores like Autozone, or you could rent one if you don't want to buy. If you have any sort of a discount tool place, you can find a 3 pc set for about $20.

Thanks! I am going to try some penetrating oil and then some whacks with a hammer. The lock nut is off. If all else fails, then Auto Zone here I come.

I'd go easy with the hammer, last thing you want is to mess up the transaxle.

If you have a piece of angle iron or decent size bar stock around, you could drill holes in it to line up with two opposing remaining holes in the hub, get two longer bolts, and use that as a puller. The up side of a puller is that you can leave tension on it say over night, after soaking it, and it may slip loose by morning. The down side is that you could mess up the end of the threads if you're not careful.

Thanks for all the advice. I went to Autozone and rented a puller and bought a can of penetrating oil. I tightened it down as far as I could and sprayed. Every few hours I would tighten it and spray it and it popped off the next morning!
