Lite-Trac

Lite-Trac is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lite-Trac rather than just read about it. In short: Lite-Trac is a trading name of Holme Farm Supplies Ltd, a manufacturer of agricultural machinery registered in England and based in Peterborough. The Lite-Trac name comes from "lite tractor", due to the patented chassis design enabling the inherently very heavy machines manufactured by the company to have a light footprint for minimum soil compaction.

Key takeaways

Lite-Trac belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lite-Trac to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lite-Trac from memory before moving on to harder problems.

Reference excerpt

Lite-Trac is a trading name of Holme Farm Supplies Ltd, a manufacturer of agricultural machinery registered in England and based in Peterborough. The Lite-Trac name comes from "lite tractor", due to the patented chassis design enabling the inherently very heavy machines manufactured by the company to have a light footprint for minimum soil compaction. Holme Farm Supplies Ltd agricultural products, sold under the Lite-Trac name, include tool carriers, self-propelled lime and fertiliser spreaders, sprayers, granular applicators and tank masters. Lite-Trac is currently the manufacturer of Europe's largest four-wheeled self-propelled crop sprayers. The company's products are identifiable by the combination of unpainted stainless steel tanks and booms with bright yellow cabs and detailing.

History Lite-Trac had existed as a name since before 2006, with first prototypes built in 2004. Following the success of initial testing, Lite-Trac was incorporated in 2008 to develop and manufacture the SS2400 Tool Carrier with its patented chassis layout. Since then Lite-Trac has gone on to develop its own crop sprayers which exploit the potential of the SS2400 chassis and has branched out into spreading and granular application.

Products Lite-Trac manufactures a range of agricultural machinery.

SS2400 Tool Carrier The Lite-Trac SS2400 is a tool carrier with a 14 tonne payload capacity. The patented chassis layout with its mid-mounted driveline gives equal weight distribution on all four wheels. The fully mechanical driveline is particularly suited to heavy work in hilly conditions and includes a 6 speed automatic power shift gearbox with locking torque converter which is capable of 50 km/h. It also features a 260 horse power (194 kW) engine, air suspension, anti-roll bars and a forward mounted cab.

Sprayers When it comes to self-propelled sprayers, there is big and bigger. Then we come to the Lite Trac. A Lite-Trac crop sprayer, or liquid fertiliser applicator, mounts onto the SS2400 Tool Carrier centrally between both axles to maintain equal weight distribution on all four wheels and a low centre of gravity whether empty or full. The stainless steel tanks are manufactured in capacities of up to 8,000 litres, whilst Pommier aluminium booms of up to 48 meters can be fitted, making these Europe's largest four-wheeled self-propelled sprayers. Lite-Trac also manufacture bespoke sprayers.

Spreaders Agri-Spread high capacity demountable spreader mounts onto the SS2400 Tool Carrier and is specifically designed to take full advantage of its 50/50 weight distribution. The spreader is capable of spreading a wide range of materials including fertiliser, fibre foss, lime and poultry waste. The standard hopper can hold up to 12t lime, or 5.6t fertiliser, and extension sides are available for lighter materials. Spreading widths of 24m and above are achievable at rates of 20 kg/Ha to 4t/Ha, subject to the product.

Granular applicators Lite-Trac pneumatic applicators for precision application of slug pellets and Avadex are manufactured in widths of up to 36 metres.

Worked examples

Example 1 — a first encounter with Lite-Trac

Start with the simplest possible case. Write down what Lite-Trac claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lite-Trac before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lite-Trac ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lite-Trac

In research: Lite-Trac appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lite-Trac in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lite-Trac is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural machinery manufacturers of the United Kingdom, Engineering companies of England, English brands, so understanding it makes those chapters shorter.
In everyday life: Look for Lite-Trac outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
