Location Of Scraper Transmission Neutral/Run Switch In Operator Compartment | |
The scraper transmission neutral/run switch has two functions.
When the scraper transmission neutral/run switch is in the ON position, the scraper transmission control disengages. The scraper transmission is placed in the NEUTRAL position. When the scraper transmission neutral/run switch is in the OFF position, the scraper transmission control will be engaged. The scraper transmission will shift when the tractor transmission shifts.
The scraper transmission neutral/run switch has a secondary function. This secondary function checks 13 lights that are on the electronic control module (ECM). When the switch is in the NEUTRAL position, all 13 lights must turn ON. For further information, refer to Schematic, "657E Wheel Tractor-Scraper Electrical System" and refer to the Service Manual, "Electronic Programmable Scraper Transmission Control".
