Mowed Wheat Stubble/Chaf Landing

Its that time of year again. Those amber waves of grain and grass seed are being harvested. Last year I fell a couple of dead trees in to the wheat field and used my pickup to "skid" them over to where I planned to cut up fire wood for the winter. The farmer that rents the land had harvested the wheat and had then mowed the stubble right down to the ground a few weeks later. This left loose mowed stubble, and chaf on the ground. ( No, I am not talking about standing wheat stubble ) I hooked up to my truck to pull the small cedar logs away and promptly began to spin my tires like I was on ice. After work was done, I decided to do a little brake and steering test. I'll use aviation terms such as "Good, Fair, Poor, and Nil". Steering was Fair to Poor depending on how much loose mowed stubble was under the tires at that particular moment and place of the field. Braking was Poor. :shock: It didn't take much to lock up the brakes and slide.

Seeing how a Pizza Fly-in was due in two weeks, I made sure to alert my guests to plan accordingly with landing distance and braking. All had a good time and comments on the slickness were noticed.

I just wanted to pass this along to you that its is not the same as landing on a turf airstrip, as the blades of grass are anchored in to the dirt with roots. I talking about landing on loose material that reduces your effective braking dramatically.

Keep that in mind, and be safe out there.
Thanks for reading.

Re: Mowed Wheat Stubble/Chaf Landing

Hey BR! Thanks for the info. Interesting and not something I've thought about, but something I instantly remembered when I read it. This Fall I'm planning on landing at the field behind my dad's house which has wheat on it, so this was good info to read!

One of the best landing and takeoff surfaces for floats when there is no water.

When I used to stack small square bales of oat straw on a rack being pulled behind the baler, I'd have to make sure not to slip where there was an accumulation of straw----definitely slick stuff. I've never been around flax but understand it's even more slippery.

Re: Mowed Wheat Stubble/Chaf Landing

Good point. I never much worried about braking on stubble because the fields are usually big. But landing long to save taxitime could cause a problem. The other issue I've experienced on stubble was a field with a lot of loose straw on top of soft sandy soil. Makes for a long takeoff run if you can get off the ground at all. #-o
