Equipment Focus: Newest technology Fendt Vario 700

Scorching on the heels of its sister firm providing a premium tractor kitted out for digital farming, Fendt has been exhibiting off its newest Vario 700 fashions constructed across the new AGCO CORE 75 engines.

These newest machines are utterly new to the Fendt line-up, though sharing comparable energy rankings with present fashions, a state of confusion which ought to ease over time because the older ones are phased out.

All new tractors

To assist issues, the brand new tractors are additionally labelled Era 7 they usually slot in on the prime of the phase with the ability availability stretching from 203hp to 303hp.

The brand new engine is AGCO’s newest CORE75 which is designed to be adaptable to a number of fuels and meet stage 5 emissions requirements from the bottom up.

Thus far Fendt is the one model underneath the AGCO umbrella to utilise this engine; we is not going to be seeing it in Valtras till the Finnish firm’s sixth technology of tractors is launched, which is prone to be in 2025.

Fendt has taken a novel strategy to engine enhance, somewhat than the engine reply to demand from the ability take-off (PTO), it will increase its output by as much as 20hp to compensate for secondary energy drains, similar to air con and the alternator.

Low revs and fewer elements

All through the design course of, the overriding concern was to maintain the engine revs as little as doable and cut back the variety of elements.

Peak torque is held from 1,150rpm to 1,500rpm with most energy changing into accessible at this larger determine. It’s not an engine for revving onerous and its much less hurried soundtrack takes just a little getting used to.

Fendt claims an total 15% discount in gasoline use over quite a lot of duties in relation to the final engine of this energy ranking, on account of this philosophy and different modifications.

Retaining it cool

One of many extra notable of these modifications is the novel strategy to the design of the cooling package deal which, we’re advised, can save as much as 1.3L/hour in contrast with the normal association.

The primary change is that fan is located on the entrance of the cooling pack and so pushes air into the radiator matrix, somewhat than attempting to drag it by means of.

Making use of a constructive strain to the entrance of the radiators ensures a denser circulate of air, versus a fan drawing it, which depends on a drop in strain to trigger motion, leading to a smaller mass passing by means of.

The better the amount of air that travels by means of, the extra warmth shall be carried away, which is then vented out of the aspect of the bonnet on this newest 700 mannequin, somewhat than have it circulate over the engine.

Additional consideration to element is present in the primary cooling fan which has a really fantastic tolerance between the blade ideas and the shroud, lowering turbulence and rising its effectivity.

That is doable because of the radiator meeting being mounted independently of the engine, isolating it from the vibrations that might in any other case dictate a better clearance.

Twinned transmission

The Vario 700 seventh Era sequence has inherited its transmission from additional up the Fendt lineage. The CVT just isn’t new, it has been within the 1000 sequence for a number of years now, so it may be counted as properly tried and trusted in tractors of 500hp+.

Often called the TA190 it differs significantly from the usual CVT in that there are two inner pumps, one for every axle.

This association is a bit more advanced and costly than the traditional model, nonetheless, it does have two nice benefits.

The primary is that every axle is powered individually, permitting a tighter turning circle, whereas the second, is that the system routinely applies energy to wherever there may be probably the most grip.

It’s, in impact, two transmissions condensed into one, and the system might be distinctive in that rear and entrance axles share the identical engine however completely different transmissions that function independently of one another.

One other function of the TA190 is that there’s simply the one vary to deal with subject and highway operations, whereas the usual sort has an A and B vary to cowl these two conditions.

All new entrance axle

Throughout improvement of the newest Vario 700 sequence, the transmission proved to be so efficient that it ripped aside the usual entrance axle.

The corporate confronted a selection, it might have have deserted the concept of becoming the transmission, or it might spend extra money on designing a brand new entrance axle.

The latter was chosen and it’s due to this concentrate on engineering options that Fendt holds a premium worth out there.

The entrance axle of a turning car all the time travels barely additional than the rear, this distinction will be accommodated by the newest transmission which eases stress on the entrance drive prepare, reduces tyre put on, eliminates soil injury by means of scrubbing and is altogether extra environment friendly.

With the tighter turning circle comes better potential for using a fron- finish loader, and right here Fendt has designed a front-end loader that’s suited to the dimensions and form of the tractor, it’ll solely match the Vario 700 sequence.

Contamination free cab

The cab is claimed to be the one part carried over from the sixth Era 700 sequence, nevertheless it has not gone with out some adaption and modernisation.

It’s now doable to suit a class 4 filtration system for crop spraying, and positively pressurise the cab to make sure vapours can’t enter by means of door and window seals.

The filter might then be simply eliminated for different operations to reserve it from clogging.

Central Tyre Inflation (CTIS) just isn’t a regular function on Fendt tractors. Nevertheless, the place it’s provided as an possibility, it’s enthusiastically taken up, 85-90% of UK farmers will tick the field when ordering.

But this nonetheless leaves the query as to what tyre pressures ought to be set at. A calculation which, Fendt believes, ought to be left to the tyre corporations with suggestions for subject and highway use.

But, there are such a lot of variables concerned it’s tough for any definitive reply to be supplied, thus it’ll come all the way down to common steering and expertise.

Nevertheless, with the flexibility to manage tyre pressures from the cab, there may be at the very least the choice of normal and handy adjustment.

Full manufacturing of the brand new Vario 700 fashions will begin after the summer season refit of the manufacturing facility with the primary deliveries of pre-ordered machines within the autumn.
