GACOTTON - 12/8/2025 23:40 I'm not sure I have ever posted on here before, but I have gained allot of knowledge and saved allot of money researching on here. I am wanting to put an ATC 300 steering system on one of our 8400 tractors. Does anyone know what the installation manual number is so I can research what parts I will need and what is involved in installing it? I have the manual to install on older Sound Guard Cab tractors, but I cannot locate the manual for the 8000 series tractors. Thanks Mike
