![]() Choose the right features to satisfy specific needs – check out the value and benefits for each option to determine which one is the best fit for the work.Tractor compatibility – if there is a tractor the operator will be using, look for the tractor compatibility sheet to identify appropriate options.The amount of time and frequency it will be used – for longer hours and more frequency, choose a heavier duty machine.The size of the area to mow versus the size of the machine – the bigger the area to mow, the bigger the mower needs to be to perform efficiently during mowing hours.Control undergrowth and grass in orchards, vineyards, and groves.This is essential in no-till and minimum-till fields. Knocking down stalks such as cotton, corn, or milo speeds up decomposition.Cutting grass waterways encourages root development and helps prevent erosion.It is the most cost-efficient way to cut roadsides, parks, cemeteries, airport fields, hydro, gas, and telephone easements, and all other types of open properties.Routine cutting keeps weeds from reseeding.Cutting grass and stalks helps control insects.Clipping pastures encourages grass growth, optimizing on valuable pasture acreage.Here are situations when a rotary cutter provides value: John Deere rotary cutters continue to advance in value with larger, more powerful gearboxes, and updated constant-velocity (CV) drivelines. To help promote safe operation, John Deere rotary cutters are equipped with front and rear safety-chain shields and lighting kits to comply with U.S. The cutting chamber design allows the material to flow through the area and be discharged evenly throughout the width of the machine. Valuable features are included such as a dome-shaped smooth deck, which prevent water and debris from accumulating on the top of the machine and makes it easy to clean up.īuilt with a superior structural design that will satisfy different applications and segment desires, the single deck on the flex-wing cutters adds volume on the cutting chamber, allowing the machine to process more material and translating into an improvement in cut quality. John Deere flex-wing rotary cutters lead the way with innovative design, superior durability, and proven performance. With a slip clutch, it is the same, except that with a powerful tractor you get about two seconds of "it sounds a touch different" to raise the cutter out of what bogged it down or shut off the PTO before the slipping clutch starts to smoke and you're going inside to eat lunch while it cools off, or it will just slip as soon as you re-engage the PTO.NOTE: Only for E, M, and R flex-wing models. I also used that Bush Hog behind a 27 HP compact, it never sheared a pin, it just killed the tractor's engine. You knew you sheared a pin because the cutter sounded ever so slightly different, tractor didn't know it even happened. We sometimes would go through 10-15 pins in a day when we were initially reclaiming parts of fields that were left fallow for years. We had the Bush Hog behind an ~80 HP tractor growing up. If you have saplings and brush or a bunch of mole hills, you will either shear a good number of pins if your tractor is powerful enough to do so, or you'll kill the engine if it isn't. If your tractor isn't particularly powerful, you may never shear a pin. If you don't have much for mole hills and such and are just cutting grassy weeds, the only way you'd shear a pin is if you have a powerful tractor and push the speed too fast and plug up the cutter. Changing a shear pin is pretty quick, carry the wrenches and a punch in the toolbox with the extra pins and nuts and lockwashers and it's a 2-3 minute task to change a pin unless you drop the nut or lockwasher in the grass and have to root around to find it.Īs far as how often pins get sheared, that depends on how powerful of a tractor you are using and what you are cutting. I would say a slip clutch is a little more of a pain in the behind if you are in a situation where it slips more than once or twice in a moderate period of time, it then gets hot and won't hold much power until it cools off. However, there is zero maintenance with a shear pin like there is for a slip clutch. From my experience, the only real advantages of using a slip clutch cutter are that you don't have to replace shear pins, nor will you ever run out of shear pins. I have an MX6 which like all MXes only has a slip clutch, and growing up we had a shear pin 5' Bush Hog. I have used cutters with slip clutches and shear pins, and would definitely vote for the shear pins.
