Types of clutch plate ( and material used in their facing)

Clutch is a essential part that links PTO (Power Take-Off) to the engine and gearbox. Understanding the different types of tractor clutches and their maintenance is essential for prolonging your tractor’s lifespan and enhancing its efficiency—whether you’re a new buyer or an experienced farmer looking to upgrade. Let’s explore the various classifications of tractor clutches.

Types of tractor Clutches Based on Operation

Single Clutch assembly

This simple clutch system runs one friction plate to control the PTO as well as the gearbox. It stops the tractor and implements at once. It is ideal for small-scale farming. The limitation of this clutch is that the PTO is limited while the clutch is pressed, therefore limiting operations. For example: the Swaraj 735 FE tractor has a single clutch. 

Dual Clutch assembly

The dual-clutch can operate two clutch plates (transmission clutch and PTO clutch) with a 2-stage longer pedal that is utilised twice during gear changes—once to move to neutral and once to the intended gear. It is designed for heavy-duty implements like rotavators, harvesters, etc., needing exact control. Benefits include less gear grinding, less fuel consumption and help to synchronise gear speed. Swaraj 742 XT is one of the tractors using this clutch.

Double clutch assembly

There are two clutch plates in this system—one for tractor movement and another for PTO operations. There is a hand lever called IPTO (Independent Power Take-Off) for handling the PTO clutch and a foot pedal for controlling the transmission. Double clutch, like the one used in Mahindra yuvo tech+ 575 DI, is ideal for mid-sized to large-scale farms with several implement uses. PTO operates outside of the main gearbox and improves multitasking; hence, you can easily stop the implement without stopping the tractor. 

 

Types of clutch plate based on disk Facing

Type    Temp. (°F) Best Use
Woven Organic   600 Daily Driver
HD Organic   700 Most Street Performance, Towing, and Hauling Applications
 Ceramic    1000  Racing
 Feramic    1000  Racing/Agriculture
 Feramalloy    1000  Heavy Duty Hauling and Towing; Commercial Trucking
       

 

ORGANIC (White Facing)

Organic facings are typically made from phenolic resins, friction modifiers like metallic powder or metal oxides, and compounded rubber. These facings come in two types:

Molded Facings,  We do not Recommend to use this. 
Woven Facings, which include fiberglass yarn woven into the material to increase strength. The burst strength of an 11″ OD/6.5″ ID woven facing is over 10,000 RPM.

As you can see, woven organic facings are much stronger than molded facings, which translates to better life and performance.

Woven organic friction materials are commonly used in OEM applications, as they offer a good combination of smooth engagement, wear resistance, and strength.

Summery.

In almost all cases, woven is better than molded. For most vehicles, a woven organic clutch offers the best combination of performance, durability, drivability, and cost.

HEAVY-DUTY ORGANIC (White Facing)

Heavy-duty organic clutch facings are similar to normal organic clutches in terms of engagement smoothness, but with more temperature resistance and durability.

Heavy-duty organic clutch facings feature more metallic content, which boosts heat resistance and reduces fade.

This gives these clutches resistance to temperatures as high as 700°F, at least for short periods, as well as increased burst strength.

Summery

Heavy-duty organic facings are just fine for most towing, hauling, and street performance applications. They’re temperature-resistant, strong, and durable but still smooth.

 

CERAMIC (Black Facing)

Ceramic clutch facings are composed of a blend of copper, iron, tin bronze, silicon dioxide, and/or graphite. The material is sintered or brazed onto a backing plate and often riveted to the main clutch plate.

These facings can endure high temperatures—up to 1,000°F—without fading, making them ideal for racing applications. However, it’s important to note that ceramic clutches typically have a high ratio of static to dynamic friction, which can result in more abrupt engagement.

FERAMIC

Feramic clutch facings, with their high coefficient of friction and high static-to-dynamic ratio, are primarily designed for racing applications where quick lock-up is paramount.

Composition and Design

These facings are constructed from a blend of steel, silicon dioxide, tin bronze, and graphite. Feramic facings can cover the entire clutch face (full-face) or be designed as smaller contact points (buttons).

Carbotic Facings

A specialized variation, known as a carbotic facing, is used in truck applications. This material provides ceramic-like temperature resistance while still allowing for smoother engagement than standard racing feramic.

FERAMALLOY FERAMIC

FeramAlloy facings are poised to replace traditional ceramic facings. They offer comparable wear and temperature resistance but feature a significantly improved static-to-dynamic ratio, resulting in smoother engagement and notably less chatter than ceramic materials.

TIPS FOR MAINTENANCE

Checking oil level: – Every Rotavator use oil in their shaft gear box and Rotary gear box. Oil helps gears to work smooth and it also reduce heating while working in the field 

So when working in the field check oil level every after 2or3 days. To avoid extra expenses or waste of time during heavy work load.

Cleaning soil and dirt :- while working in the field heavy soil stick under the rotary  it reduce the rotavator speed and harm the body      So clean all soil from the rotavator in every interval of work.

Use Of Cross :- do not use damage cross because it disturb the alignment connection PTO shaft to rotavator shaft 

Spare Parts :- Always consider to replace spare parts not use welding replacement of parts keep your rotavator strong

Which engine oil is best for a bike—

mineral (conventional)
Fully synthetic
Semi-synthetic

This question arises in the mind of almost every rider. The job of engine oil is not just to reduce friction but also to keep the engine cool, clean, and prolong its life. For this reason, choosing the right oil becomes important. 

Let us understand these three types in simple terms.

Mineral or conventional oil is made by refining base oil. It is the most economical option and proves adequate for everyday normal riding.

However, its performance may be limited in high temperatures, high revs or prolonged hard driving. Due to its comparatively lower oxidation resistance and deposit control, it needs to be changed relatively frequently.

Fully synthetic oil is chemically engineered, making its molecules more uniform and stable. As a result, it provides better protection in both extreme heat and cold, flows faster during cold starts, maintains film strength at high revs, and generally contributes to better mileage and engine longevity. 

It is usually expensive, but in many cases can extend drain intervals, provided the manufacturer’s recommendations are followed.

Semi-synthetic oil is a blend of mineral and synthetic oils. Its cost and performance lie in the middle—better thermal stability and cleanliness than mineral oil, but not as high performing as full synthetic. For daily office commutes, moderate distances and normal riding, it is considered a balanced choice, especially if you do not want to spend entirely on full synthetic but desire better protection than mineral. So, which should you choose? 

First, check your bike’s owner manual—it clearly states the viscosity grade (such as 10W-30, 10W-40), API/ACEA and JASO (such as JASO MA/MA2)

specifications. Engine CC, your riding style (city traffic vs highway), weather/temperature, service intervals, and warranty conditions also matter. For general use, semi-synthetic is often sufficient.

full synthetic can be beneficial for performance riding, extreme temperatures, or long highway rides. Only go for unnecessarily expensive oils if needed and approved by the manufacturer. If in doubt, consult the brand’s customer care or an authorized service center—and yes, let us know which oil you use in your bike!

Tractor hydraulic problem and solution

TRACTOR HYDRAULIC PROBLEM
There are many ways to deal with tractor hydraulic problems as the issue can range from oil leaks to faulty pumps, faulty filters, air leaks, overheating, and even sluggish running.
Slow or weak performance
If your tractor implements respond slowly to lift or perform, the system probably is not creating enough pressure.
Low fluid levels: The simplest reason for poor operation is low hydraulic fluid. Refer to the reservoir and top off with the fluid recommended by the manufacturer as necessary.
Clogged filters: A dirty or plugged hydraulic filter slows down fluid flow, causing the system to lag. Change the filter per your tractor’s service schedule.
worn hydraulic motor: The hydraulic pump is the system’s backbone. When it is worn, it will be unable to provide sufficient pressure and flow. It can be diagnosed by looking for low pressure, strange noises, and inefficiency.
Overheating
Heat may damage oil seals and run out the hydraulic fluid, causing premature component failure.
fluid level: Low fluid makes the system have to work harder and produce more heat.
Incorrect gear oil : Use of the wrong viscosity gear oil may compromise the system’s capacity for heat dissipation. Only use the fluid that the manufacturer recommends.
Excessive load: Driving under heavy load for a long time can tax the system too much and make it overheat.
Erratic or jerky movement
Irregular or stuttering hydraulic movement is frequently the result of air contaminated in the fluid.
Air leakage: Air may enter the system through loose fittings or leaks in suction side pump. Check all the hose and fittings for damage or loose clamps.
Fluid contamination
Dirty hydraulic fluid can do severe damage to your system by destroying seals, clogging filters, and wearing out components.
Water contamination: If your hydraulic fluid appears whiteness, it is water-contaminated, which can rust parts and deteriorate the fluid’s properties.
Dirt : Dirt particles can find their way into the system via external leaks, dirty couplers, or maintenance.
Leaks
Fluid leaks cause loss of pressure, decreased efficiency, and possible environmental risk.
Worn hoses and seals: Check all hoses and seals for cracks, damage, or wear and tear.
Loose fittings: Inspect all fittings and connections to make sure they are securely tightened.
Damaged couplers: Quick-connect couplers may leak because of damaged internal O-rings.

My tractor is not racing what should I do

My tractor is not racing what should I do

  • Reason behind the tractor is  not racing, (power drop)
  • Fuel Supply. Sometimes various types of garbage get stuck in the tractor tank. The fuel supply is not reaching the pump properly. Either the pipe is blocked, the mesh is blocked, or the Diesel filter is stuck by the garbage. All these factors cause obstruction in the fuel line.
  • Fuel Pump. Sometimes the race setting in the fuel pump gets messed up. Because of this, the tractor has difficulty in acceleration. and also tractor speed and power
  • Clutch Assembly Problems. If the tractor’s acceleration is full or fast. Then the clutch and pressure plate can also be a reason. Because the clutch and pressure plate wear out over time. It is necessary to change these. If the clutch plate is old and worn out. Then it does not transfer full power from the engine to the gearbox. The tractor cannot run fast and with power. And this is why the engine also overheats.
  •  Adjustment of clutch pedal. Make sure the clutch pedal is fully released. A loose clutch or pedal clearance problem can cause a decrease in power transfer.
  • Tyre condition is also a reason of power drop.
  • Air Filter: A clogged air filter can also hamper engine performance.
  • SOLUTION.
  • Clean the tractor tank and fuel lines
  • change diesel filter
  • Get the pump settings adjusted by a mechanic.
  • Change the clogged air filter with new one.
  • And if all this doesn’t work out
  • Then go to a mechanic and get the clutch and pressure plate checked. If it is damaged, replace it with a new one.
  • Hope your tractor will be fine. and work as new one.
