hi I am new here, found my way here from the Redpower forms
Anyway last year I did 6 weeks on one farm in centrail Queensland driving the road trains to the crain depot, 8 johndeere headers (combines) all had a chain draging from the rear to control the static, remember geting onto one header as it was unloading into my truck at about 7.00pm it was dark and I got one big shock as I went onto the lader! could see the spark real clear! yes even with a chain draging on the the dry ground, must have come from my truck I had just driven back 35ks.
And we did have a fire that got away, one header driven by a new driver had a pully driving the straw spredder do a bearing and droped sparks that started a fire that stoped harvesting for the day and did take 6 hours to put out, think that cost about $250000 in lost wheat and time.
Hot dry days with wind in wheat, and then fire is not going to be good!
Jake.
