dodge78 90 #1 Posted August 10, 2011 My friend got a Homelite tiller model R-4C chain drive. It has a Kohler k91t on it. The serial tag is gone but we can read " erial 7 43" with the rest not being legible. We are guessing the engine is a 1975 but the tiller looks to older than that. The handles are quite wide on the ends. Anyone have any info on these things or someplace to do some digging on it? All thoughts are appreciated. Share this post Link to post Share on other sites
