The black knob is used to add resistance to the rear wheel. I tried several units this by far the best and is whisper quiet.

What reusable bolts are you refering to? Could you possibly provide a link?

No, I believe what you are calling the bolt is actually the plastic or metal nut that locks down the blade and it is available for purchase separately.

I just used the bolt I had. I didn't buy any. Just took old ring off and then put this one on.

Probably not. The outside rollers are to prevent your boat from scraping on the bolts if it should slip to the side of the roller when loading or unloading.

The bolt is separate. That said, I think the parts are pretty much standardixed across brands. I can't answer the second question since they're installed.

It is a bolt that goes through the bracket, really. You could swap it for whatever bolt you need. That's what I did.

don't get this.. it won't work. it will just strip the bolt head. Instead, get a hack saw blade- the ones with just a small handle and saw the top of the head, it will just snap off eventually . Or saw just below the head if you can get to it.

I do not remember . . . But i think they used to include a new set of bolts. Sorry.

I had to buy bolts as well. The original spindle that came on the mower deck from the factory was threaded and made things a little easier.

It is a metric size bolt; M5. Mine broke the first night setting it up so I grabbed an M5-32 x 25 mm. Internal Hex Socket Cap and pack of 206 rubber O-rings from a hardware store. I replaced the plastic washer on the threaded side with the O-Ring and left the plastic washer on the tightening side. 1,000 times better now; doesn't move at all.I wanted it fixed immediately and figured there was no point getting a replacement from Blue if it's just going to break again.

you loosen a nut/bolt, set desired angle, then tighten back down. Love mine

If I remember correctly, there were 2 different size bolts. Check www.grassgator.com for more info.

Mine attach to metal brackets that clamp onto the metal track that the garage door rollers ride in. I don't know what hardware you have. Mine installed easily. Look at the attached link on eBay, and maybe that will help. http://www.ebay.com/itm/like/181303373409

Rollers on the rail. I've found it to be pretty smooth and I'm right up a the weight limit for the machine.

It is some sort of a mechanical interface with bolts and friction involved. It did not fit my external mirror, so I have not installed it yet. I am thinking how to fix it using other means. If you do not want to spend a lot of time trying to figure out how to fix it - do not buy.

The roller has a lock brake. To hold it tight, I haven't had issues but I guess you could add something at the bottom.
