Thanks for that info. I have been reading here obout the slip clutches and I was wondering if anyone has a good site to purchase one I had read about those and the driveshaft issues along with the 2 different KK hogs and the 2 rear wheel one for the 2305. The slip clutch sounds like a good insurance policy as it seems all these implements have a 40HP shear pin in them even though they are rated 20 HP and up.
Some of the implement sellers include a slip clutch with the drive shaft. , at least as an option. My Land Pride RTR0550 tiller came with the slip clutch as an option. Shear pins can be obtained for differing break strengths. I used a grade 0 1/4 inch bolt on my old LP rear mower that I used with my Yanmar, but for the lighter duty 2305, I'd go with the slip clutch. You can adjust them to suit your needs, and the instruction books show you how to set them up.
The important thing is to disassemble it before you use it, and clean the clutch disc and plates, because if they sit out in a dealer's yard in the rain, etc, they can get stuck together. I even took off half the springs (there are 8 total) to lower the tension on the clutch for my X748's tiller. I can still bury the tiller without the clutch slipping, but it will quickly let go if I hit a rock or root. There is some setup involved, but once set, it's pretty much a leave-it-alone gizmo. Just keep it out of the rain so it doesn't get stuck together, if it sits for a while, and be careful not to get grease or oil on the clutch disc.
