I have a jiffy mod 30 and the problem that I have is that it cuts very hard. I put a new blade on it still no change. I sharpend the edges of the point and still no change....It will cut but you have to push down real hard...and that is a problem for me cause I am a short guy......Thanks for the help
I had the same problem on my early 80's model 30 7" auger. It was cutting hard and at the point of busting through the bottom of the hole the blade would get stuck and kill the engine. I examined the blade and pilot point and they looked fine. We still used it until it finally happened. THE METAL PLATE THAT THE BLADE IS MOUNTED (SCREWED) ONTO BROKE. tHE FACTORY WELDS BROKE. I had it welded but we couldn't get that factory angle back. After having it welded twice, I decided to call jiffy.
Jiffy said to send it in and they would fix it. All it would cost is shipping on my part. They did ask if I wanted a new drill assembly at $113-135 cost. They did mention that they had factory demo drills available and that they didn't put this on their website because of low inventory and high demand. These 'used' drill assemblies are used by their pro staff for one season or less. Price: $78.00 (including shipping). I ordered on tue. and received it on thurs. I now have a well-tuned, iced drillin' machine!
So, check your mounting plate, if broken call jiffy for repair details or order a factory demo, if they are still available.
Good Luck,
