"I cut holes in the front and rear of my grain cart so I could see highway traffic traveling down the road," says W. Harvey Roberts, Shawboro, N.C.

"There's 19 miles between our farms and I don't fold down the unloading auger when traveling. Being able to see traffic coming up behind me, I can get far enough off the highway so cars and big trucks can pass, me safely.

"The front hole is 9 by 9-in. square and the two side-by-side rear holes are 11 by 17-in. each. I installed a thick sheet of 1-in. plexiglass over the holes and, after 8 years, I can still see through clearly and the plexiglass has never broken. I also put a small 9 by 9-in. hole in the lower front of the cart so I can see how much grain is left in the cart when unloading into my trucks.

"I strongly feel that all grain cart manufacturers should be required to install windows in their carts to make them safer on highways."
