    I've had this machine for 15 years and love the damned thing even though we seem to spend more time together with my toolbox than cutting the grass :headscratcher: (more of a problem with the mechanic than the machine, I'm sure) Anyway, the question is if anyone has experienced issues with the...

    Hello all, I just joined up and I feel like I just dove into the deep end of the Case, Colt, Ingersoll world. My father had a 1970’s Case 446 since the early 80’s which I inherited along with the job of doing all the lawn and garden work. A few months ago the Onan engine gave out with a broken...
