I received the BCRM175 a few days ago, it took me the better part of a day to put it together because the directions are not very good. The directions need better step-by-step instructions and explanations.

Between looking at videos and their online pics, I was able to get it together. I mowed about half our horse pasture and it did great. Just tall grass, no saplings.

This video was very helpful to see the orientation of the arms etc.
I felt some vibration at the end of the first mow so the next day I checked the hammer blades and found a couple that had loosened. I removed, cleaned, and retightened each with red loctite.

I used a 36mm cresent wrench to check the 4 arm bolts. They all moved a little, but the last one moved the most, so I gave it a little more and "pop". The bolt/pin hexagonal head popped off. Upon further inspection, it was poorly welded on and rust could be seen on the inside. I could not find a replacement bolt anywhere (specialty fastener store in downtown Nashville, TSC, ACE, online, etc.)

After a delayed response and me calling a person named Ralph, who seemed suprised that I called him about the mower (his number is the number in emails and on the website). I did get an email from Jack (the engr), that they are going to send 4 new bolts from the factory in China.

It did a good job when it worked, it was significantly cheaper than the Peruzzo ($3350 vs. $8650). It weighs about 1000 lbs, 300 lbs heavier than the Ironcraft/Cosmo. So we'll see how it holds up. The rest of the hardware is either grade 8 or 10, besides these one-off bolts on the arm. I wish the design used something easier to find, but you get what you pay for.

Bolt #4 is the broken one. The arm came labeled for the wrong model and the numbers didn't match up, lots of improvements could be made in the manual.

I just received mine, as well. So far I have abused the hell out of it (and found 4 tires buried in the brush that were sucked up), and it keeps trucking along.

I could be wrong, but I believe "Jack" may have a presence here on TBN. I recall a flail mower engineer named Jack helping folks out in a few threads.

Why does the bolt heads look so funky... Looks like special fabrication (faulty) for what ever purpose it serves...

Jack Yuan, has been a pretty standup guy. He’ll help get it all sorted out.
Those “bolts’ do look rather cheesy.

Looks like a pin with a hex head tacked on, somebody can do better than that

Yes, I think so, unfortunately. I couldn't find any close replacements anywhere. They had to ship replacements from the factory in China. This is the first major flaw I've found on the mower. They should have designed the arm with standard bolts.

Why did you replace graphic.... Please bring back original do we can see poor weld on "nut welded to pin"........

Thank you didn't see the arrow(s) but pic #7 was what my original reference was too.... I would bet with a little effort and a few mods you could actually find something the would work better the the Chinisum bolt....But then something better would probably void warranty...
