SWMN | Yes one 1682 received a long cleaning system but it never went into production.
Typically new pull type models lagged the self propelleds by year. They are simpler machines but none the less they required testing. The 1682 w/1010 offset pickup header went into production in 1987. We started with one machine in 1985 running it SD, ND and into Canada. I believe we used a 4694 tractors to power all the field test units. Their was a 1010 offset header either 17.5 or 20' on it to direct cut part of the time. None of those were ever produced. The second year we 2 prototypes and one started in KS direct cutting. Both were in SD, ND and into Canada hitting both SK and AB. One may have made it as far North as the Peace River in Alberta.
For you tractor aficiandos these large pull types pushed tractors of the times to their limits. One of the last 1482 tests in the early 80's still IH days included evaluation of an elusive vari-range 2+2 tractor for a short period. (I didn't witness this but was involed in making the combine available, someone else was present at the test site). As I mentioned 4694's were used for the bulk of the 1682 work, but a Magnum prototype was used during the EMI testing mentioned below and another one was used in AZ for the Product Acceptance Testing in the spring of 1987. One of the first production 1682's was shipped to AZ to direct cutting of flood irrigated barely. This was done in April hence the need to go to such a foreign place for a pull type. That test was powered by a prototype Magnum, a 7140 with a straight front axle. Part of the IH legacy was new products have to go through a series of inspections and tests to allow shipment of completed machines. Testing this early allows the machines to be shipped from the factory.
The 1682 was little different in structure and main drives/components than a 1482. Although it looks simple production release of is a complex task. First all the parts needed have to be identified. Sometimes its only a paper exercise but new features require design, build and testing. The 1682 had the increased rotor/concave wrap which was just a paper exercise. The windrow pickup/reel drive was a new hydraulic drive so a test stand was built to evaluate it. Field units had temperature data taken to evaluate cooling. The control box/grain loss monitor were new so that required a complete environmental/cycle test in the laboratory to insure reliability over time. Finally near the end of the program a unit was taken to a vendor facility for Electromagnetic Interference Testing. (This is basically bombarding a machine in a copper screened enclosure with radio/micro waves to insure something like a two way radio or passing a radio tower does not cause something to happen which would cause unexpected consequences. ) | |
