Tractor PTO Slip Clutch Friction Torque Limiter

The tractor PTO shaft slip clutch (Friction Torque Limiter) is a coil spring clutch used to limit the amount of torque transmitted at a calibrated value by slipping the friction disc while maintaining power transmission. It also helps to absorb peak torques during the start-up of high-inertia machines.
Torque limitation is ensured by the slipping of the PTO slip clutch assembly over 2 or 4 discs of special material (asbestos-free). The value of the calibrated torque can be adjusted by modifying the compression height of the coil springs. A PTO safety slip clutch is supplied with 2 or 4 friction discs and works in both directions of rotation.

How Does a PTO Slip Clutch Work?

The basic function of this PTO safety slip clutch is to protect tractor implements. When a tractor implement becomes jammed due to a heavy workload or securing a load, the PTO will continue spinning and cause irreversible damage to the implement. A tractor PTO slip clutch engages between two friction plates and takes the load off the implement, thus protecting it from costly damage. Each implement has its own unique tension settings.

There are several factors that contribute to the proper setting of a slip clutch. To check if the slip clutch is properly set, measure the amount of force applied to the PTO shaft and the spring scale. The spring scale should be adjusted to 87 pounds. If the slip clutch does not have the correct setting, adjust the bolts to achieve the desired amount of force. In order to test a slip clutch, the center of the PTO shaft must be 6.75 feet away from the eye bolt of the spring scale.

The slip clutch limits the amount of torque transmitted to an implement by limiting the speed of rotation of a power plate. Its friction plates transfer force to the gearbox. The power plate is made of high carbon steel, which is rust-proof and durable. To adjust the slip clutch torque, you can adjust the bolts on the PTO and friction plates. Make sure that the bolts are not too tight, as too much tension will shorten the life of the friction plates.

PTO Slip Clutch Installation

The first step of PTO slip clutch installation is to install the tractor's rotary tilling implement. Attach the rotary tilling implement to the PTO and lower it to the ground. Engage the tractor's PTO and raise the implement to operate speed. Once the tractor is stopped, set the parking brake and engage the clutch. Check for proper slipping by checking the position marks on the rotary tilling implement's hubs.

A slip clutch is a simple device that protects the equipment. Tractor PTO shafts use a slip clutch. A Bush hog rotary mover is one example of an implement with a slip clutch installed. For a cost-effective and reliable installation, consider purchasing a rotary mover. PTO slip clutches can also be installed on passive implements, such as lawnmowers and balers.

A slip clutch is a simple piece of equipment that protects your PTO and implement agricultural gearbox from the force of a moving implement. A slip clutch is easy to install and maintain and provides a safety line in the event of damage moving up the line. While this device is simple to install, it does require special knowledge and training. Remember that great power and torque can cause damage to the tractor equipment. It can prevent costly tractor repairs by protecting PTO-driven equipment.

How to Remove a PTO Slip Clutch?

The main key to removing a PTO slip clutch is identifying the issue. When the clutch is faulty, it will need to be replaced. The correct way to remove the PTO slip clutch is by following the steps outlined in the following paragraphs. You'll need a permanent marker and a paintbrush.

To install a new slip clutch, the bolts must first be adjusted. Follow the instructions that come with the equipment to ensure proper adjustment. To loosen the bolts, count the number of turns that you make while loosening them. Once they are loose, restore the clamps to the correct positions. Care should be taken to keep the slip clutch in a dry place away from water. If the clutch does not function properly, it may be due to excessive heat, or it may have a bad smell.

Our PTO slip clutch assemblies are designed for side or in-line loading. With no direct load on the engine crankshaft, they are an excellent choice for heavy-duty applications. They can be manually or hydraulically engaged. If the PTO slip clutch fails to engage, you may need to remove the PTO.

Tractor Pto Slip Clutch

PTO Slip Clutch Vs Overrun Clutch

A slip clutch is a mechanical device that allows PTO driveline power to be given at the business end of an implement. This prevents damage to the implement. A slip clutch differs from an overrun clutch in several important ways. In general, a slip clutch is preferable in areas with a lot of obstacles, compacted soil, or hard-to-reach spots. These differences should be understood when deciding which type of clutch is best for your needs.

A PTO slip clutch is often preferred by tillers. These machines often encounter obstacles in the field and have difficulty transferring 100% of the torque. However, the PTO will continue to turn, which is what makes it ideal for workarounds. The difference between the overrun clutch and slip clutch is the amount of resistance the PTO shaft experiences. When the overrun clutch breaks, the tractor will continue to rotate without having to rotovate, which extends the life of the PTO drive shaft.

A PTO slip clutch can also be used in situations where a tractor fails to engage the PTO drive. A slip clutch is designed to break power when a tractor reaches an extreme load. For instance, a large log, rock, or stump may be caught in the tines of a tiller, causing slippage. If the PTO slip clutch breaks, the power is lost. The tractor's transmission or implement gearbox may malfunction.
