I don't understand PT's not working with you on the spindle warranty. For machines in the warranty period, my experience and what I have heard from others is generally that they were quick to send replacement parts. Bubenberg had spindle failures, but I think after the warranty period. I haven't had any spindle problems in two seasons with the 6' rough-cut, but the spindles are probably at least bigger, if not a different design. Sorry you've had trouble.
The rear wheels on the decks (and guide wheels on the snow blades) have been a problem for everyone. My deck tires had foam filled tubes. Ultimately, they twisted off the rims. On the snow blade, they're nicely inflated in warm sunny weather, and flat with bead off the rim when it is snowing and dark. How do they know? /forums/images/graemlins/confused.gif
Despite some minor frustrations, I've been pleased with the 1845. You're sure right about the manuals or lack thereof. The 1845 manual is good only for maintenance, not repair, and attachment manuals are nonexistent. But, I have some manuals that are 50 pages of silly warnings with no useful information. A good shop manual, written for someone who owns a few wrenches, would be nice, but I don't need one that says not to try to unbolt the mower blades while they are spinning, or advises not to put your hand on top of a post while driving it with the post pounder.
