Another update to my Titan story. The Titan rep asked me to check back with him after the 4th of July to make sure he had all the parts. He did not, and instead chose to ship me another brand new 72" flail mower. I received it last week. I couldn't be happier with Titan's service. In some ways, I now know exactly what I have and will be more cautious on some things, and less cautious on others. For example, I find the flail knives that come on these mowers to be extremely durable. So I'm less concerned about those. However, I now know heavy rock impacts (with large rocks) *can* bend the drum enough to cause shaking, which is catastrophic for the rest of the mower.
Now that I have the new mower, I plan to remove the rear roller and turn the bearing mounts 90 degrees so that the grease zerks point out backwards instead of straight down where they have virtually no clearance and get easily destroyed. I will also find a way to better secure the front chain guard rod so it doesn't back out and lose the chain. Lastly, I've debated removing the scraper bar on the roller. I'd like to have it gone, but suspect it may help maintain structural integrity between both roller mounts which are not heavily reinforced.
Here's a pic of unloading the new replacement mower:
