That's not my tractor...

Product Information

The speed increase does not apply to other agricultural machines such as sprayers and combines. Also, wider tractors over 2.55m and under 3.5m (and that includes the width of what you’re towing, too) are still restricted to the 20mph limit. This significant increase in gross train weight will allow bigger tractors, up to 6.61t heavier, to pull laden trailers more safely this harvest.

This involves dropping the oil, recovering the air conditioning gas, lifting off the cab and removing the propshafts.Once it has been taken out, the process of rebuilding or replacing it with a reconditioned unit can begin. The first tractor built by the Hart-Parr partnership in 1901 featured a 70hp engine with oil cooling It can then be lifted off with a telehandler or forklift, welded and replaced. The job takes roughly eight hours to complete.

It is important to emphasise that this increase only applies to agricultural tractors towing a trailer. Tractors pulling what is called an “agricultural trailed appliance” (a baler or crop sprayer, for example) must still observe the 20mph limit.

Provisional licences Any person who is assisting an individual with the training of a vehicle should be at least 21 years old or over, hold the relevant licence and be experienced with the vehicle or machine which they supervising on. It tends to give most trouble on tractors fitted with a loader, as the pump and valve are being worked frequently.

He also made efforts to find non-farming markets, and these included converting an Ivel into a military ambulance with rough-terrain capability, armour plating and space to carry medical equipment and a patient on a stretcher. However they can only take tractors and trailers on the road that are less than 2.45m wide and have two wheels, or four close-coupled (tandem) wheels. Another major step forwards in power farming versatility arrived with the Ivel tractor, built by Dan Albone, the son of a market gardener and publican. He began experimenting with engines in about 1896, and within two years had finished building his own car using a Benz engine, with his first tractor following in 1901. His first tractor, displayed at the 1900 Royal Show, featured a 20hp petrol engine, a belt pulley and a platform at the rear for carrying up to three tonnes.

The maximum combination weight of a tractor and single trailer has increased from 24.39t to 31t. However, the maximum laden weight of trailers remains unchanged at 18.29t. This includes three-axle trailers with road-friendly suspension and top-notch brakes. Why has the trailer weight not increased? The Huber company, a leading steam engine manufacturer, was more successful, diversifying into tractor production in 1898 after buying the Van Duzen engine company. Its tractor success continued for more than 40 years. Their mobility meant much greater versatility, attracting contractors and large farms while providing a worldwide growth opportunity for British industry. Despite the increase in weight and speed, the industry should still not be using agricultural tractors solely for haulage.

The history of the tractor began in the late 1880s, when petrol engines provided an alternative to steam, which had driven the power farming revolution for almost 100 years. Case abandoned development work on this 1892 experimental tractor and continued making its successful steam engines Bear in mind that steam power in the 1890s had almost 200 years of development behind it and was relatively reliable, while the four-stroke petrol engine had been around for less than 20 years and its primitive ignition and fuel supply systems were often troublesome.
