Hopefully if I did this correctly, you'll see two attached photos. The deflector has a 1" mesh screen on it and it allows dirt, small rocks, etc to fall through. But when it does, it hits the end of the screen. I want all my material to flow from the top to the bottom of the screen. That leaves me with more good material and less material I need to "re-run" because it ended up in my trash pile or rock side.
My TC-40 can lift the machine as it has a total lifting capacity of 2,000 lbs. however, when I originally bought the machine, I used the bucket with some of those clamp on forks which reduced my lifting ability by maybe 500 lbs. I have since purchased some pallet forks and that made a big difference. But this is a big machine and I take it real slow moving it. I have a 72" bucket on machine too and that works really well. Scoping the dirt after it's been screened is very easy... Plenty of room and the sides are reinforced in case you bump them. This unit is very stout... It will take a lot of abuse.
I asked OMH to out it together. Brad was fair in what he charged me. It's pretty easy to put together, but the parts are very heavy and it's best if you have two or three people helping to put it together. I put the vibratory pack and the deflector on, though.
I also have two foot sides on my trailer, although it's a 16' car hauler with at least 7' of width. I didn't have a problem getting on/off over the sides. However, with a smaller trailer you may need to take one side off...but it will be very close as the holes for your forks is about two feet up.
The mesh that comes with the unit works great to screen for dirt. I'm using it to screen sandy loam that has tons of river rock. I also purchased the 2" square mesh to re-screen my trash pile... This gives my good material for a foundation or road base as it has mostly rocks that are half and inch to 2" in size.
A couple other things to consider. There are attachments that OMH has that allows you to slip into the holes to pickup the unit with a bucket. These are ok if you don't have forks. However, I found it easier to use forks and it keep the unit closer to my tractor...meaning better control when moving. There are also extension legs that allow you to change the angle of the deck. I like these because you can decrease the deck angle and slow the material down... Very useful with the vibratory pack and you end up with less good material in your trash pile. The one thing about the leg extensions I don't like is it limits how you can scoop up the trash pile... You mainly have to come straight on... It would be great if you could also come perpendicular to the unit without hitting the leg extensions.
After 5 years of looking at the BCS tractors, I finally bought one to replace my dead riding lawn mower... It's still in transit, but I'm anxious to get the unit as it looks like a great tractor. How do you like your BCS?
Hope this is helpful. Let me know if you have any other questions.
