Stone in bunkers

    Have a couple of bunkers where the sand got too shallow and the rake stirred up some stone. Looking for options others might have used in the past. I have heard of walk behind screener machines. We have a small Royer screener and are thinking of pushing the sand into a pile and manually screening it.
    Any other thoughts?

    Thanks

    How big is the trap? Maybe just remove all the sand ? Wadsworth Golf Course Construction built our golf course and used a one foot wide backhoe bucket to dig the trap drainage trenches. The trenches are around 2 feet and backfilled with pea gravel to about 4" lower than the trap bottom. The pea gravel is covered with 4" of sand over the pea gravel plus what ever the sand depth is in the rest of the trap. We are in Wisconsin so the deeper drain tile lines are nice so they don't freeze in the winter. There is one trap that has shallow drain lines and we have to wait until the frost comes out of the ground in the spring for it to drain.

    Have seen the boxes that go in the bottom of the traps to help get water into the drainage lines? The same thing can be done with a deeper/wider trench and more pea gravel. We have never pumped a bunker in the 23 years since they have been installed. Wadsworth used rigid SDR 35 pvc pipe with holes in it for drain lines. You are never going to crush one of those lines.

    Miltona makes a nice screen rake, just send a couple of guys in there with those and buckets and in no time most of the rocks well be taken care of.

    I have tried a few different manual screen techniques...essentially sifting the surface. It takes a lot of labor and you end up with a temporary fix, as the stones simply migrate to the cleaned surface over time. I was going to look into this machine but haven't done it yet...I think it is what you are looking for. Let me know what you think.
