The latest generation of Loadall telehandlers for the agricultural market from JCB benefit from the company’s high–torque, low–emission Ecomax diesel engines along with a host of detailed technological developments, each contributing to more efficient use, easier operation, lower running costs and ultimately, greater productivity.
Developed to meet the EU’s Stage IIIB emissions standards, the JCB Ecomax engine has no requirement for costly diesel particulate filters (DPF) or for exhaust after treatment fluids, resulting in low–cost, efficient operation for customers.
“JCB has looked at every aspect of Loadall performance, from the engines to transmissions and hydraulics, JCB’s chief innovation and growth officer, Tim Burnhope, said. “We have completed more than 110,000 hours of testing and invested more than £80 million to deliver the most efficient range of engines for our customers, each designed specifically to work with our construction and agricultural machinery.”
JCB’s Ecomax diesel engines incorporate an advanced combustion system that manages emissions within the engine rather than having to rely on expensive after–treatment. Through the use of cooled exhaust gas recirculation, a high–pressure common–rail injection system using up to 2,000 bar injection pressures and a variable–geometry turbocharger, JCB Power Systems has been able to meet the emissions standards while developing additional power and torque, yet using less fuel.
There are three engine ratings available to agricultural Loadall customers. A 108hp engine is standard equipment in the Agri Loadall and in the 526-56 (the 526-56 Plus model has been discontinued). This engine offers 15 per cent more torque and 10 per cent more power than the previous engine, delivering increased performance for the customer.
The Agri Plus comes as standard with the 125hp engine, and although it offers slightly less outright power, the 125hp engine delivers three per centmore usable torque across its operating range than the previous 130hp engine that it replaces.
The Agri Super comes with a choice of either the 125hp engine or the 145hp motor. The 145hp motor is now a standard fitment in the Agri Xtra and the 550-80 Agri Plus.
Although the range-topping 145hp motor offers the same power rating as the previous Stage IIIA engine, it delivers three per cent more torque and provides up to five per cent more useable power in the main operating range. All models deliver average fuel savings of up to five per cent compared to the previous machines, resulting in substantial cost savings throughout the ownership period.
In the 125hp and 145hp mid-range Loadall models, transmission gear shift selection has now been placed within the head of the main servo lever, eliminating the need for a twist-grip gear change lever on the steering column, while forward and direction control can be operated from either the main servo lever or the column stalk (dependent on model).
This removes the need for the operator to take their hand off the servo lever during operation, maximising productivity and comfort. In addition, on Agri Super and Xtra models JCB has removed the various transmission operating modes, providing operators with a simple choice of auto or manual gear changing modes.
With the transmission controls in the lever head, the optional transmission dump function is moved to the brake pedal. This allows full engine power to be applied to the hydraulic system, without the transmission driving against the brake system, reducing wear and cutting fuel consumption, ideal when undertaking bulk handling applications such loading grain lorries or cleaning out livestock buildings. In addition high back-off brakes, which literally pull the brake pads away from the disc to prevent drag, are now standard on all models. They contribute a two per cent efficiency gain to the driveline.
This is further improved by reduced transmission oil levels, cutting churning losses and drag within the transmission. The PS750 Powershift gearbox now uses one litre less oil, while the PS764 saves 1.5 litres of oil. This reduction in drag contributes a further one per cent efficiency gain.
The revised engine cover and pod now direct cooling air from the top of the front canopy, around the engine and through the cooling pack, to exit at the top of the rear of the canopy. This prevents cooling air disturbing dust and debris on the ground below the engine, prolonging air filter life and reducing dust on site for the operator.
Despite the aggressive new look, complete with updated JCB colour scheme, the designers have not had to sacrifice JCB’s legendary visibility across the engine. As there‘s no bulky particulate filter or exhaust after–treatment to accommodate beneath the engine canopy, there has also been no requirement to extend the wheelbase or chassis length of the Loadall, as with some competitors, so the machines also maintain their respected manoeuvrability and tight turning circles.
In the cab the Loadalls feature a completely new instrument cluster and dash layout with a high–resolution LCD monitor. The front dash installation has been restyled for a clearer layout and the cab heating and ventilation system now features a seven-speed fan, providing greater control for the operator. The operator’s seat now comes complete with an operator presence switch as standard, preventing the machine drive being engaged without an operator at the controls, greatly improving farm safety. The top half of the cab door now comes with a revised slam latch mechanism and door ajar facility to ensure that the window stays open if required.
