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.

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

  • 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.

How to maintain Rotavator

How to maintain Rotavator

TIPS FOR MAINTENANCE

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.

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 and blades  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

Inspection of farm  :- Clean the field before plowing Because the fields have Big stones rope which can damage the rotavator. The rope clings to the blade and damages the oil seal

Inspection of blades:–

Bolts break off from the blades during ploughing, causing the blades to jiggle around more often. and damage to the blades Always check and tighten loose bolts for the further damage.

Bearing :- Always use good quality bearings, they last longer.

Why We Use Coolant in Tractor

Why We Use Coolant in Tractor

Coolant in a tractor is used to regulate the engine’s temperature

preventing overheating and ensuring optimal performance. It helps dissipate heat generated during engine operation, protects engine components from thermal damage, and maintains efficient functioning under heavy loads or high temperatures. Proper cooling also extends the engine’s lifespan and improves fuel efficiency.

Water vs. Coolant

Feature Water Coolant
Purpose Primarily for cooling For cooling and engine protection
Freezing Point Freezes at 0°C Contains antifreeze, prevents freezing
Boiling Point Boils at 100°C Higher boiling point, prevents overheating
Corrosion Protection No Contains additives to prevent rust and corrosion
Lubrication No Yes, lubricates water pump and parts
Color/Additives Usually clear, no additives Often colored, contains corrosion inhibitors


Water vs. Coolant: Understanding the Differences and Features of Coolant

When it comes to maintaining the optimal temperature of engines and machinery, choosing the right fluid is crucial. Two common options are water and coolant. While both serve the purpose of heat transfer, they have distinct properties and applications.

Water: The Basic Cooling Medium

Advantages

  • High Thermal Conductivity: Water is excellent at absorbing and transferring heat.

  • Availability and Cost: It is inexpensive and readily available.

  • Effective in Short-Term Use: Suitable for temporary cooling needs.

Disadvantages

  • Corrosion: Water can cause rust and corrosion in metal parts.

  • Freezing Point: It freezes at 0°C, which can damage engines in cold climates.

  • Boiling Point: Boils at 100°C under standard pressure, limiting its effectiveness at high temperatures.

  • Scale and Mineral Deposits: Can lead to mineral buildup, reducing efficiency.

Coolant: The Specialized Fluid

What is Coolant?

Coolant, often called antifreeze, is a specially formulated liquid designed to regulate engine temperature and prevent damage. It is typically a mixture of water and chemical additives.

Features of Coolant

  • Antifreeze Properties: Prevents freezing in cold weather.

  • Boiling Point Elevation: Raises the boiling point, allowing the engine to operate at higher temperatures without boiling over.

  • Corrosion Inhibition: Contains additives that protect metal parts from rust and corrosion.

  • Lubrication: Provides lubrication to water pump and other moving parts.

  • Color and Additives: Available in various colors (green, orange, pink) for identification and contain dyes and inhibitors.

Types of Coolant

  • Inorganic Acid Technology (IAT): Traditional coolants with silicates and phosphates.

  • Organic Acid Technology (OAT): Longer-lasting, with organic acids.

  • Hybrid Organic Acid Technology (HOAT): Combines features of IAT and OA

WHY DOES TRACTOR GET OVERHEATED

by

Why Does Tractor get Overheated

Farmer brothers

  • If it is working time in the field and the tractor stops in the middle of the field with a hissing noise, then understand that the day’s work is lost. Now think, neither time is valued nor diesel is saved and on top of that the hard work in the field also comes to a halt. 
  • Tractor getting hot means overheating, this is not a trivial matter. , damage to the engine, damage to the pocket too.
  • Now the question arises that why does this overheating happen?
  • Actually there are some small but dangerous reasons behind this. Like dirt getting deposited in the radiator. Like sweating on the forehead in summer, 
  • lack of engine oil, the body also does not run without oil. How will the tractor run? 
  • Less coolant, the condition is like not getting cold water in summer. 
  • The fan belt is loose,  it will slip
  •  Or pulling the tractor with more load than required. Meaning your own weight is 50 kg and you are trying to lift a 200 kg sack.
  • And Thermostat dose not work properly while water pass out through thermostat it’s getting stuck  due to dirty water  and corraision
  • Now what is the Solution  for this?
  • The Solution is very easy . 
  • Clean the radiator. Check the engine oil and coolant. That too on time. Get the fan and belt tightened. This is what gives air to the engine. And yes, give as much load as you have. Tractor is not Superman. 
  • Now think if you do all this then what will be the benefit? 
  • First the engine  will run for a long time. Second, saving of diesel. Simply saving of money. Third, completing the work on time. Neither the labourers will run away nor the owner will get angry.
