My 2009 New Holland won't even crank over. I've checked the seat safety, and the main fuses. the battery is good. It's like the starter won't even engage. Does anyone have any suggestions as to where I can start to look to fix this? I'm looking to start on the simple to work toward the difficult. I need to get it running so that I can plow my driveway. UGH!!! Any help would be greatly appreciated!!
