Hey guys, I'm a newbie here to the tractor family. I puchase a used Branson 3510i last year to help around the 5 acres I purchased to build a home. The tractor set under the barn this winter. I did go out one time to start the tractor in December with no problem. We were out this past weekend, I started the tractor on the first start, great I thought. I pulled it out drove it around the barn cut it off and now will not start. Any ideas what this may be. Battery is good and I can hear the fuel pump when I turn the ignition on. Any suggestions will be very appreciated.
