power tiller

Types of power tillers

A power tiller is a machine designed to break up and aerate the soil. It is also known by other names, such as soil tiller, garden tiller, power cultivator, and rotary tiller. The power tillers work on the principle of rotary motion, where the engine rotates the drum or tines. Power tillers can be classified into five types based on their choke, control system, drive, fuel type, and working mechanism.

• Handle type:

  In a power tiller, the handles are fixed at the sides and pushed manually. It is usually considered a walk-behind tiller. This type of tiller is easy to control and suitable for small and open spaces where operators can walk between the tilled rows. However, it is only sometimes practical for large areas.

• Handlebar type:

  This kind of power tiller allows the operator to control the tiller by holding its bar. These tillers are more stable and easier to maneuver than the fixed handle type. They are suitable for moderately sized gardens and farmland.

• Mini power tiller:

  A mini power tiller is commonly used in small vegetable farms, orchards, and nurseries. It is compact and lightweight, which allows for easy transportation and operation. Power tillers are affordable compared to bigger tillers and usually come with a four-stroke engine.

• Walk-behind power tiller:

  Operators walk behind this tiller as it cultivates the soil. It is designed for smaller plots and is considered to be one of the easiest tillers to operate.

• Ride-on power tiller:

  These tillers are designed for larger cultivated areas and have more power. Since they are larger, they come with a seat for the operator.

• Front-tine tiller:

  The tine rotors of a front-tine tiller are located at the front of the tiller. As the tiller moves forward, the front tines break up the soil. These power tillers are suitable for small to medium-sized gardens and fields.

• Rear-tine tiller:

  In a rear-tine tiller, the rotary tines are located at the back. Compared to front-tine tillers, rear-tine tillers have better tilling depth control.

• Chain drive:

  In a chain-driven power tiller, the chain transfers the engine's power to the rotor, which then tills the soil. They are durable and suitable for various agricultural applications.

• Gear drive:

  A gear-driven power tiller uses a gear mechanism to transfer the engine's power to the rotors. Gear-driven tillers offer precise control and are ideal for working in tough soil conditions.

• Petrol power tiller:

  Petrol-powered tillers are more powerful than manual tillers and are suitable for home use where electricity is not available. These tillers work with two-stroke and four-stroke fuel engine varieties.

• Diesel power tiller:

  Diesel power tillers have more power and higher fuel efficiency than gasoline-powered tillers. They are suitable for larger farmlands.

Specifications & Maintenance of Power Tiller

Specifications of power tiller

• Horsepower:

  The amount of horsepower for a power tiller will differ based on whether it is a garden tiller or a larger tiller for agricultural uses. Smaller tillers may have less than 1 horsepower and function with a crank-shaft tilling head. Larger tillers will have 5-10 horsepower and use more straightforward engines.

• Machine weight:

  For hand-held power tillers, the weight is a significant consideration since the operator must control and maneuver it. Weighing less than 20-30 kg is essential to allow for easy handling and transportation. Larger tillers designed for standalone operation in extensive agricultural fields can have more significant weight, around 100 kg or more, depending on their size and capabilities.

• Working width and depth:

  The working width refers to the tilling width of the power tiller, which is determined by the number and size of the tilling blades or shovels. The working width typically ranges from smaller dimensions (20-40 cm) for garden tillers to larger dimensions (80 cm or more) for tillers designed for agricultural use. Generally, more extensive and deeper tilling capacities are associated with larger power tillers intended for significant agricultural applications. For instance, a garden tiller may achieve a tilling depth of 15 cm, while an agricultural power tiller could reach depths of 25-30 cm.

• Drum type and speed:

  Power tillers employ a variety of drum designs to mix and pulverize soil. Common drum designs include slotted, bar, shovel, and intermittent modes, with slotted drums being the most frequent. The frequency at which the drum rotates is another vital consideration. For most power tillers, the drum speed will be between 1000-1500 RPM. It may vary according to the kind and purpose of the tiller.

Maintenance of power tiller

Regular power tiller maintenance extends its life, prevents unexpected breakdowns, and improves efficiency.

• Daily checks and cleaning:

  Do a complete inspection of the power tiller before use. Check for loose, damaged, or missing parts. Ensure all guards are in place. Clean off any soil or debris from the tiller after each use to prevent clogging and protect components. Pay close attention to the cooling fins of the engine, fuel system, and air intake. Inspect belts and chains for wear or debris; don't forget to wash the power tiller with a garden hose to remove dirt or buildup. Allow it to dry thoroughly before storing it.

• Weekly maintenance:

  Each week or after about 5-10 hours of operating time, perform more in-depth maintenance. Check and adjust belt tensions as needed. Lubricate all grease fittings and pivot points, especially on tiller blades and drive components, using a multi-purpose grease. Drain and clean the fuel tank; inspect filters and water separators as per the manufacturer’s instructions. Clean the air filter element and inspect the fuel lines and hoses for leaks or wear. Replace the air filter element if it's damaged or overly dirty.

• Monthly and quarterly tasks:

  Every month, check engine oil level and top up as needed. Change oil every 25 hours or yearly, whichever comes first. Monthly inspection and cleaning of spark plugs is also essential. Check the spark plug gap and electrical connections every three months or after 50 hours. Other critical components like belts and chains need to be checked for proper tension and lubrication to keep them in good shape. Make sure the tiller operates at optimal temperatures by inspecting and cleaning the radiator.

• Seasonal service:

  During planting or harvesting seasons, do a more in-depth inspection and service of the power tiller. Thoroughly wash and clean the entire tilling assembly, including blades and shovels. Replace the oil and inspect all filters. Check major systems like fuel, cooling, electrical, and tilling mechanisms. Condition and lubricate any chains or belts that show signs of wear. Make these seasonal checks part of the operating routine for maximum efficiency during essential farming periods. Scheduling regular inspections is equally important. It will help get the tiller ready for peak planting or harvesting months.
