Hi guys. registered a few days ago and been reading and learning alot for the past two months. Wish I had abetter 1st post but - here goes- Was obviously not being a "good" operator today and laid my Cat 257 over on her side. NOBODY HURT! well i hope nobody, I tried 1st to kill machine but it would not turn off. it choked itself to a smoky halt after about 15 long seconds. I ran to the dozer ( a jd 450c) and straightened her up after she had been on side for about 12-15 minutes. I waited about three hours and toped off the oil(about 1/2 gallon) and tried to start. She just tried to turn but the engine never turned kinda like something stuck. What should I do? Never had this happen in my life and need help so i can go finish job tomorrow hopefully!
