That's not my tractor...

Product Information

If you’re stopped, any defects found can open the driver and owner to prosecution by road traffic law enforcement agencies or the police. Accessing the packs involves taking the wheels off, jacking up the cab, removing the diesel tank and hydraulic pump, dropping the back-end oil and removing a number of wiring looms. It is important to emphasise that this increase only applies to agricultural tractors towing a trailer.

Tractor mechanic, Matthew Morgan details some of his recent repairs and offers a few tips to reduce the likelihood of a breakdown. This involves dropping the oil, recovering the air conditioning gas, lifting off the cab and removing the propshafts. It was demonstrated to senior officers who tested the armour plating with rifle fire, but apparently took no further interest in an idea that might have saved lives in the First World War. Britain was the world leader in developing agricultural steam power, and the earliest record of steam working on a farm was in Wales in 1798, when a stationary engine was employed to drive a threshing machine. Engine sales totalled more than 32,000 units and included one that generated electricity for the lights on the Statue of Liberty in New York and another lighting up the Taj Mahal in India.The low pack covers speeds one to six, medium does seven to 12 and high does 13 to 18, so if there’s no drive in one of those ranges, it’s relatively easy to pinpoint the offender. After this setback John Froelich left the company, which stopped making tractors and concentrated on petrol engines. The single-cylinder engine used in the tractor developed 20hp, but other sizes were available and it was a huge success for Hornsby. He attempted to put more gas into the cylinder, which caused oil to pour out, highlighting that the diaphragm had broken down. When these have been replaced, Mr Morgan always recommends fitting clear caps so that the operator can quickly monitor the oil level and the condition of the bearings.

As agriculture employ many seasonal workers from outside the UK it is important to understand the rules around temporary residents as non-UK driving licences are not always comparable with UK driving licences. A BOAT is defined as “highways over which the public right of way is for vehicles and all other kinds of traffic, but which are used mainly for the purposes for which footpaths and bridleways are used”. If a Quadtrac’s rear linkage won’t stay in the correct position, it’s likely that the potentiometer is the problem.Farmers and contractors can, of course, use tractors for moving produce, as part of the agricultural operation, within current limitations for operator licensing. In the mid-1890s more American newcomers arrived on the fledgling tractor scene, including the Otto company that had supplied the engine for John Charter’s first tractor in 1889. While it is all frustratingly slow for farmers, this is a step in the right direction for more closely aligning the legal position to the reality of our industry. But other British pioneers took a very different approach by developing lighter, more versatile tractors to replace horses for field work. Another 1892 newcomer in America was the tractor built by John Froelich, an agricultural contractor with a business that included steam-powered threshing equipment.

It tends to give most trouble on tractors fitted with a loader, as the pump and valve are being worked frequently. Thankfully, the back-end filtration is pretty good on these tractors, so small amounts of swarf don’t tend to cause lasting damage. The sales boom enjoyed by Britain’s agricultural steam engine manufacturers continued during the 1880s and 1890s, and it probably left little time or enthusiasm for experimenting with tractors. The Hart-Parr company was still making tractors in 1929 when it lost its identity in the merger that formed the Oliver farm machinery company.Special versions of the tractor included a narrow model built to navigate the rows of a French vineyard, while a tractor adapted for an Australian fruit grower was probably the world’s first orchard tractor.
