Loader provides plenty of grunt

Seeming more monster than Master, JCBs new 416S loader

boasts the hydraulic muscle to lift a full turn tip load of 5.3t.

Andy Moore gave the 150hp machine a workout

SLOTTING in above the 414S and 412S models, JCBs flagship 416S Farm Master loader could be considered a force to be reckoned with.

Maximum full turn tip load with the chassis straight is 5334kg, which is halved to 2667kg with the articulated steering on full lock.

The 416S shares the same Perkins engine and build as the 414S, but is equipped with a more efficient hydraulic piston pump instead of a gear type to improve lift capacity.

Other differences between the two include beefed-up lift and crowd rams together with an 800kg counter balance weight and stronger rear axle.

farmers weekly caught up with the 416S at one of JCBs test centres near Uttoxeter, Staffs.

Before climbing aboard, a quick tour around the machine reveals the machines general build and service points.

At the back, all main engine service points are conveniently accessed by opening two side panels and a rear bonnet. The left-hand engine bay offers a fuel filler – positioned on its own with no sign of the more usual service items, such as oil filler, engine dipstick and air filter.

These are positioned more centrally on the right-hand side along with fuel filters. Opening the rear bonnet reveals two batteries and a well screened radiator complete with removable chaff screens.

Not so easy to access

Not so easily accessed, however, is the radiator header tank. Topping up requires the operator to balance on one of the rear mudguards. Service points aside, it was time to checkout the cab, which is accessed via three steps – the bottom one pivots to avoid damage from ruts and obstacles.

Once seated in the cab, the operator is surrounded by a less than spacious, cosy environment, although a liberal amount of glass allows good visibility.

Forward visibility is optimised through use of two widely spaced crowd rams rather than the traditional, sight restricting Z linkage arrangement found on conventional loaders. For controls, the layout falls neatly to hand, including single joystick, auxiliary lever, climate control dials and forward and reverse shuttle.

Positioned in front of the joystick is JCBs Electric Monitoring System (EMS) screen, which displays among a host of other information, engine rpm, hours worked and gear selection. After turning the ignition key, with the shuttle in neutral and the handbrake engaged, the 6-cylinder turbocharged Perkins engine comes to life.

For speed selection and direction changes within the hydrostatic transmission, the loader offers a choice of shuttle or joystick. A twist grip on the shuttle selects speeds one to four – for in the barn to fieldwork, or automatic position for speeds one to six. In automatic position, the transmission works its way up and down the speeds according to the acceleration and deceleration of the loader.

The other transmission control is via the joystick – a neat idea which features a rocker switch to select forward, neutral and reverse directions.

This function is useful when manoeuvring within a confined area and allows the operator to keep his left hand on the steering wheel.

Joystick versatility

To enable transmission joystick control, the shuttle is locked off from a button located on the steering column. Other joystick versatility includes button selection of working speeds one and two, while a further switch instigates transmission free-wheel.

In our test, transmission free-wheel proved effective when driving the 3.2cu m high tip bucket straight into a heaped pile of grain. When the switch is pressed, drive is automatically disengaged, allowing more power for lifting the loader arms.

Working in speed one, the 416S displayed impressive torque reserve when driven into the grain heap with little effect on engine revs and rear-end stability until the bucket was full to its 2.8t payload

Complete raising of the bucket takes about four seconds and is carried out in a progressive, positive manner, while lowering requires a steadier hand considering the weight of the bucket and the hydraulics extreme sensitivity.

Another handy function of the joystick is the pre-set bucket position mode that enables the bucket to return to an exact horizontal position after tipping or previous lift height after lowering. Both functions are instigated by clicking the joystick to one side.

In regard to turning circle, the loaders 40deg articulated steering angle enables a tight lock to be achieved. JCBs textbook outside turning radius is claimed to be 5.3m (17ft 6in).

In summary, apart from the rather cramped cab and separated service points, the 416S appears to be a rugged workhorse capable of serious farm loading applications. &#42
