Combines M3 canvas above walkers

The canvas curtain behind straw walkers is to prevent cobs from destroying back of walkers when using a chopper. If you do not harvest corn you can remove curtain as it is not needed. Holes in canvas are not an issue as long as curtain is still doing its job. Usually we see slots in curtain from straw walkers contacting it. Hyper Harvest II

My F2 has a curtain 1_2 way back or so of the walkers.Not sure what good it does.I have a beater at front of walkers so maybe it's to stop that from knocking grain out the backIJThe one at back is like Hyper says.
