Disagree. Yes, shear pins are common on smaller 4 and 5 ft rotary cutters. The idea that they are "less maintenance" is the opposite of my experience. Slip clutches are reliable, once set correctly protect your driveline forever with no dicking around with them. They are standard on ALL larger cutters for a reason. Simply cutting corners and holding down price when shear bolts are used on the smaller cutters. Shear bolts if they ever get the slightest bit loose WILL shear. They are a PITA to replace. Often metric versus English confusion. Get the wrong one and have to replace it again. Unless they fit real snug they keep on shearing and = blasted nuisances. Any normal slip clutch adjusted to the instructions ONCE will squeak instantly when you suddenly engage the cutter and that becomes your familiar audible sign that all is well. I have had hours of wasted nuisance time with shear bolts. Never ever any maintenance waste of time with a slip clutch.
Nothing wrong with Woods. Basic cutters. If you are going to use the cutter a huge amount as your main tool then it is worth it to shop more. I recommend you shop around and find a cutter that is a little stronger and you really like. Many good brands. Bush Hog, Landpride, Deere, Kodiak, etc. all good. You pretty much get what you pay for too. Depends a lot on your intended use (light brush, weeds, heavier brush, saplings, grass, etc.) as well as how much of your time.
