5 Most Common PTO Parts for Agriculture, Farming, and Forestry Equipment

Harvan Manufacturing offers custom precision machining for a variety of industries, including agriculture, farming, and forestry. We offer extensive experience in the machining, welding, and fabrication of Power Take-Off (PTO) parts for high-torque, low-speed equipment. Over more than 30 years, we’ve expanded our facilities to incorporate 49,000-square-feet of manufacturing space for the machining and fabrication of high-precision farm and forestry machinery parts.

Even the simplest PTO components demand tight tolerances and the use of high-quality metals. At Harvan Manufacturing, our highly skilled machinists, engineers, and technicians can guarantee tolerances within ±0.001 inches for straightness, concentricity, outer diameter (OD), and inner diameter (ID). Using advanced computer numerical control (CNC) machines, Harvan delivers the highest levels of precision with short lead times.

What is PTO?

PTO components are mechanisms that transfer power from the equipment’s engine to secondary components. In field applications that require mechanical power to reach, harvest, crush, cut, or bale, PTOs are often used to transfer power from a drive shaft to a hydraulic pump or air compressor. Without power take-off technology, agriculture and forestry equipment would not possess the torque, horsepower, speed, rotation, or grip to perform the heavy-duty operations in the field.

Forestry and farm machinery use mechanical gearboxes that have robust PTO torque and horsepower requirements. Often, these PTO components connect to the equipment’s transmission to transfer power between auxiliary components. The different types of industrial power take-offs include:

  • Mechanical PTOs are used for inline or side load applications, such as pump jacks, woodchippers, and irrigation pumps. Mechanical PTOs feature a pilot bearing and a straightforward flywheel PTO with a lever-actuated manual clutch to efficiently store rotational energy and transfer it into kinetic energy.
  • Pilotless Mechanical PTOs have no pilot bearing and feature easier installation. This PTO increases side load capacity and engine life for water blasters, chippers, and irrigation pumps. Pilotless PTO components provide greater uptime for heavy-duty operations.
  • Type 1 PTOs see use in rock crushers and mud pumps thanks to their rugged construction and high-power capacity. This design is characterized by a heavy-duty, spherical bearing arrangement that reduces crankshaft loading damage at full load.
  • Type 2 PTOs feature heavy side-loading capacities, hydraulic or pneumatic actuation, and improved engine and bearing life to power road building equipment and portable rock crushers.
  • Pilotless Over-the-Shaft PTOs are used for high-demand, high-loading diesel engines. Eliminating the pilot bearing simplifies installation and maintenance.
  • GM Style PTOs offer reduced repair time and costs. The sealed main bearings of this PTO mount directly onto GM engines. The GM-style bell housing requires no special adaptations of the engine or PTO.
  • Automotive Style PTOs are a flat-faced style PTO with similar features and benefits to the GM style PTO. This PTO features a spring-loaded clutch to engage and disengage more easily than center power take-offs.

The 5 Components Often Manufactured for PTO

The following most frequently manufactured PTO components should be selected according to equipment specs and the power needs of the driven equipment.

PTO Shafts

Most farm and forestry equipment requires a means of transferring rotational power and torque from the engine to the PTO-driven machine or implement. A PTO shaft rotates in proportion to the speed of the engine, providing the rotational energy for powering agricultural implements like woodchippers, excavators, and rotary tillers. Important specs include the horsepower rating at specified RPM, number of splines and series size, and whether the shaft will be installed with a live PTO or independent PTO.

Joints

PTOs use U-joints and constant velocity (CV) joints to keep the PTO shaft transmitting power from the transmission to the drive wheels, especially on uneven and demanding terrain. CV joints are a necessary part of front-wheel drive vehicles, allowing the drive shaft to transmit power at constant rotational speed through different angles. Universal joints are common on rear-drive vehicles and are mounted on both ends of the drive shaft. When connected to yokes, U-joints allow movement along or parallel to the shaft, which is necessary when traveling over bumpy roads.

Common machining specifications for PTO joints include the outside diameter of the bearing cap, the location of the snap ring, and end-of-cap to end-of-cap measurements.

Yokes

Implement yokes assist in maneuvering heavy equipment by connecting the machine’s driveline to agricultural implements such as a power tiller, cultivator, or plow. The flange yoke is a U-shaped attachment with a flat-face that mates with a companion flange on driveshafts, resulting in a mechanical connection able to handle the torque required to rotate the driveline shaft.

Quick-disconnect shaft yokes use a push-pin mechanism for easy connection of the cross and bearing kit to the driveline shaft, while a tube yoke requires a second cross and bearing kit to connect the implement.

Companion Flanges

Companion flanges mate with a flange yoke and feature a precision-machined face, drive bore, and through holes or threaded holes for connection to the appropriate companion flange yoke. Both the yoke and companion flanges must be capable of handling high torque loads and are machined for exceptional balance.

Guards and Guard Bearings

PTOs typically rotate at speeds of 540 RPM or 1,000 RPM. Guards and guard bearings prevent accidental pull-in or caught-in injuries. A master shield to guard the tractor PTO stub and connection end in combination with a driveline shield offers maximum protection. PTO implement guards protect against unintentional contact with driveline components and protect the point where the driveline connects to the implement.

What Is CAD to CAM Engineering?

Computer-aided manufacturing (CAM) refers to manufacturing operations that utilize computer software and computer-controlled machines to achieve better product quality and/or process efficiency. It is generally used in conjunction with computer-aided design (CAD) software, which enables designers and engineers to create digital models of the desired part and product that dictate how it should look and work. This information is then loaded to the CAM software, which creates instructions for the equipment (e.g., CNC machining units) that direct them on how to create the component.

Applications of CAM

CAM has a number of uses in manufacturing facilities, such as:

  • Managing the overall production process. CAM software can be used to automate production operations, allowing for more operational efficiency.
  • Generating tool path designs. CAM technology can be used to dictate the movement of tools and equipment to ensure the workpiece is worked into the proper shape and size.
  • Ensuring equipment safety. Computer-controlled equipment reduces the risk of manufacturing mistakes as well as employee injury due to falling materials, chemical exposure, extreme heat, and other adverse conditions.

Benefits of Using CAD/CAM Technology in Manufacturing

By utilizing CAD/CAM technology in their facilities, manufacturers benefit in many ways, including:

  • Broader manufacturability flexibility. CAD/CAM software enables manufacturers to take on jobs (e.g., the manufacture of highly complex components) that would be otherwise impossible to fulfill by manual methods.
  • Better client accessibility. CAM/CAM software allows manufacturers to readily receive and process client-provided CAD models, resulting in faster project cycle times.
  • Greater project oversight and control. CAD/CAM software makes it easier for manufacturers to maintain oversight and control over various aspects of the job, including design or production updates, material inventory, and machining operations.
  • Easier programming. CAD/CAM software takes the guesswork out of setting up manufacturing units, making it simple for machine operators to input and update the necessary equipment settings. Additionally, many CAD vendors have developed CAM machining modules that readily integrate with CAD software, making it easy for new designers and machine operators to learn and use them.
  • Higher productivity. CAD/CAM software improves the efficiency of machining operations by allowing for faster speeds without sacrificing accuracy or precision.
  • Lower waste generation. CAD/CAM software reduces the risk of mistakes during the manufacturing process, which, in turn, decreases the amount of rejected pieces.

 The Valve Components We Manufacture for the Oil & Gas Industry

Harvan Manufacturing Ltd. has more than 35 years of experience in manufacturing high-quality valve components. We work with a wide range of industries, including the oil and gas sector, to manufacture parts for the valves used. Harvan is proud to be a family-owned and -operated company that focuses on meeting your production needs.

What Are the Valve Parts We Manufacture?

Harvan manufactures several parts and valve components for clients in the oil and gas industry. Some of these include:

  • Valve Stems & Shafts: Valve stems control the opening and closing of a rotary valve. Typically, there is an actuator on one end of the shaft and the ball or gate is on the other. Stems control the internal mechanism of the valve which in turn control the flow of product through the valve. We manufacture these stems out of specialty metals to ensure corrosion resistance and strength whether they control liquids or gases.
  • Seat rings: These are the sealing components inside a valve. Often, they are used to seat the ball inside of ball valves which open and close to allow the flow of material through the valve.
  • Bushings: These are used to protect the equipment. The type will closely relate to the application environment and purpose. Bushings are used to reduce abrasion, vibration, noise, leak prevention or sealing and can have a corrosion-proof functionality.
  • Other components we manufacture range depending on our customer’s requirements.

Valves play a key role in the oil and gas industry, being essential to control flow rates, protect the equipment, as well as guide and direct the refining process of crude oil. Some of the most common valves used in the oil and gas industry include:

  • Control valves provide control over flow rate, pressure, and temperature.
  • Gate valves control the start and stop of the flow of fluid. These valves cannot be open and closed easily, so they are usually left completely opened or completely closed when in service.
  • Butterfly valves are low-maintenance valves that usually have an actuator to help isolate and regulate a variety of media with low-pressure loss. The design allows them to easily fit in all pipe sizes; when triggered, they will quickly open and close.
  • Ball valves control the flow of high-pressure liquids and gases with only a slight drop in pressure. Ball valves are made in a range of sizes and materials and have fantastic operating characteristics.
  • Check valves are used to protect the equipment from backflow and pressure build up they are sometimes referred to as non-return valves.
  • Pressure seal valves are used in high-pressure services. The pressure seal bonnet protects joints while the internal pressure rises.
  • Globe valves are linear valves used for isolation and throttling services. Their tight shut-off capability makes them a popular valve choice.

Suspension Parts & Components

Vehicle suspension is essential for accurate and reliable vehicle handling. Good handling is generally measured by considering the vehicle’s road isolation, directional stability, returnability, tracking, and cornering. Together with the vehicle’s body design and steering mechanisms, these factors ensure travelers can rely on their vehicle and maneuver terrains safely.

A suspension system’s core function is to maintain contact between the tires and the road. The suspension framework supports the vehicle’s weight, absorbs shock, determines the ride height, and helps to control the wheel alignment. To execute these operations effectively, vehicle manufacturers need to provide quality suspension components.

Information about manufactured suspension parts for vehicles.

Independent Suspension for Military and Defense

In addition to basic functionality, the suspension system ultimately defines where drivers can safely operate their vehicle. Military and defense vehicles, for example, must be able to travel through rough terrain and harsh conditions. Consequently, these off-roading specialty automobiles need an independent suspension system.

Unlike standard solid-axle suspensions, an independent suspension system allows the wheels on each axle to move independently. The wheels can then adjust to uneven surfaces without transmitting the impact throughout the vehicle or changing its course. An independent suspension network increases the tire-to-road contact on uneven ground, which gives the driver more power and maneuverability.

Harvan Manufacturing offers several suspension components that are specially designed ideal for military and defense vehicles, including:

  • Control Arms: This suspension link keeps the wheels in place and aligned with the body of the vehicle when traveling over uneven surfaces.
  • Torsion Bars: This spring suspension system absorbs impact and helps to maintain a consistent vehicle height while driving.
  • Stabilizer Bars: A stabilizer bar is critical for keeping vehicles upright during sharp turns and can prevent rolling.
  • Height Management Sensors: These sensors allow for communication between the suspension system and the person operating the vehicle.
