Received my slg-78 yesterday.
Seems promising to be very useful, but I think my expectations were a bit high. I don't think it'll be as convenient and flexible as I was hoping for $7k.
Some of my "concerns" from looking at what pics I could find proved grounded although none total dealbreakers. It's designed for a machine with a stronger FEL than mine, and more importantly a flatter bucket like skidsteers etc have.
I can't really move the unit using the bucket arms on the outside, my FEL can only lift the unit inches up and only when conditions are perfect. With the bucket grabs on the inside, it's designed for a flatter bucket and my standard Kubota bucket is taller than a skidsteer style flat bucket in the front and therefor hits the cross piece and is 6 inches short of sliding into the "clamps". It sort of grabs, but barely and and the unit is heavy and awkward enough I think it could easily slip off the bucket in that position and might be exciting. I wondered about this and it seems like a problem as moving the unit with the bucket is alot more convenient that driving off, getting the forks, moving it, and then swapping the bucket back in to work every time I want to move the unit. Note, a flatter bucket like a small skidsteer bucke is very low in front, and is below that crosspiece.
I can lift it from either side with my pallet forks (because it allows the FEL pin to be closer to the weight), but that isn't as convenient and also the slots are huge compared to my forks and for example from the outside the forks angle up drastically in the slot and hit the crosspiece inside. And with the forks it seems kind of less stable than I think it would if the forks fit the slots better. One "solution" I'll try is to put a 2x4 on top of the forks once inside the slots and see if that tightens up well it sits on the forks. Peter told me it is designed for much thicker forks than mine.
It comes with a 3/4 x 4 mesh (and I ordered a few other sizes). I ran some pretty nice dirt through it and it fed pretty well. I tried some pretty nice dirt but with grass growing in it and within a few minutes it seriously plugged up the thing under the crossbar of the deflector such that I am going to have to go out this morning with a bar or something and work it clear. This was a major dissapointment (so far anyway).
So at least with that mesh it doesn't seem to like woody/grassy mixtures as they plugg up the unit under the cross bar and stop all feeding. Has to do with the limited space under the deflector bottom crosspiece and the reliance on gravity to work everything through that "narrow" slot. I am hoping I'll work out better ways to sift dirt with other stuff in it, maybe with the larger mesh first. Got so say I was expecting it to eat this mixture I was feed it right up but it plugged so bad in 5 minutes I called it a day.
After I get some time with the unit, I can report what I"ve worked out. Bottom line is moving it with my tractor is not as convenient as I think it should be, and I think it is going to be MUCH fussier about what I feed it than I hoped (at least with the deflector and the new rubber mat they have) . Taking off the deflector looks to be a major effort, so I am hoping I can figure out something that works better when trying to screen dirt with grass in it.
I've attached a few quick pics, one with nice dirt and everything working well and the other showing how my tractor style (taller towards the front) bucket hits the crosspiece and can't fit into the grab arms. I can't yet think of a solution. Maybe if I never use the grab hooks on the outside, I could have them modified somehow to allow the bucket to fit. Maybe angle the grabs slots down so the bucket is lower. If the slots themselves were lower it would work better, but that is not something I can change of course and that might foul up the balance of lifting it. Basically the unit is not really designed for the compact tractor, as that is not their usual contractor customer.
Third pic is how after maybe 5 (perhaps 10) minutes it was totally jammed with grassy dirt. I realize the unit is not designed to take dirt with grass in it, but I am really hoping to improve my techniques with this sort of material somehow with time.
