we are in an area which grows winter wheat, spring wheat, oats, barley and barley with peas. many small fields 4 to 20 acres. uneven ground. lots of straw needed for cattle bedding. can't use rotaries for that reason. we use 3 straw walker, 4 and 5 walker machines with various heads, 11', 13', 15' and soon 18'. a wagon accompanies each combine and it will hold 3 dumps of the combine. all our combines are altered. blanking plates in the concave, higher cylinder speeds, plastic front grain pans, plastic auger liners, extra fuel tanks, double grain bin extensions and lots more little things. basicly we charge $15_hr per straw walker in the combine plus $1_hr_per foot of grain header. a 3 walker combine with a 13' head is charged out at $58_hr including driver_operator. we supply a 4 wheel grain wagon that is towed by farmer's tractor and man and is charged out at $10 per dump of the combine. we will be adding a weed seed separator this year to one combine and will charge this out at $10_hr - farmer's choice - it can be bypassed on the combine. in all this , the farmer supplies all the fuel. transportation of the combines to and from the farm is charged to the farmer. our combine area was used to charges including fuel and at first this was difficult to work with , but repeat customers are used to supplying fuel now and it works well. we have worked to combine with very low losses, a very low breakdown rate, being timely to the job and just generally trying all the time to do the best we can. a diary is kept on each unit and it is reviewed at the end of season and changes, renovations, rebuilds, and new ideas are completed before the next season. we currently use MF and NH combines. each has their own strong and weak points.
