LAVERDA'S REV series COMBINE HARVESTERS
REV, meaning Reliability and returns – Efficiency – Versatility.
The actual name of Laverda’s new series of combine harvesters stands for a whole wealth of important features dedicated to all those customers who consider the economic aspect of their investments with the utmost care and who decide to purchase a reliable, efficient machine that’s so versatile as to be all-purpose.
After painstakingly segmenting the market and checking out the technical solutions at depth, we are certain that REV will help you to face the challenges of modern farm work with peace of mind, especially in consolidated markets such as France, Germany, Spain and the emerging ones in the East.
Let’s take a closer view of Laverda’s new REV series combine harvesters and discover their features together.
We’ll start with the cutting header, a part that’s of fundamental importance if the combine is to operate in the correct way. All the models in the REV series are equipped with the tried-and-tested Terra Control system. It adapts the cutting header to the unevenness of the ground and allows the cutting height to be pre-selected in two stages: from 50 to 180 mm and from 100 to 500 mm. An electrohydraulic device makes sure that the cutting header presses down on the ground in the ideal way. With its exclusive double star shaped side parts and tough adjustable cutter tubes installed on self-lubricating bushes, the reel guarantees sure-fire harvesting and feeding. The cutting blade is able to operate in an exceptional way thanks to the high speed of the spinning transmission and the exclusive self-cleaning system. The strongly built auger with retractable fingers along its entire length, complete the harvesting job by feeding the crop into the elevator housing in an even, rapid and continuous way.
The universal elevator has tough triple or quadruple chains plus bars with a high-strength profile and is pre-engineered, as part of the standard outfit, for application of the GSA system. The reliable lubricated chain transmission, automatic longitudinal and vertical idlers and constructional shape of the housing guarantee an even and unbroken crop flow from the cutting header to the threshing mechanisms. Longer lasting components and lower servicing costs are the main benefits obtained from the automatic tensioning systems.
The threshing components have been sized in an optimal way to suit all the threshed crops. They comprise a tough drum with 8 bars featuring a continuous beating profile that treats the grain in a delicate but efficient way, plus the concave with the exclusive independent adjuster mechanism on both the inlet and outlet sides and the innovative REV module.
A good threshing apparatus must quickly adapt to the changing threshing conditions so as to prevent the grain and straw from being damaged and to get the utmost from the performances provided by the combine. This is why Laverda proposes the REV module alongside the conventional tried-and tested threshing components. It comprises a post-drum (REV drum) and an extension to the concave (REV segment) that can be adjusted in 3 different positions and is the ideal component when it comes to versatile and all-purpose use of the combine.
The 20% increase to the separation surface, a winding angle that’s now 120° and the delicate way the straw is conveyed to the straw walkers, are all decisive features that contribute towards the effectiveness and success of Laverda’s REV series combine harvesters.
The long and strongly built straw walkers (4.30 m) feature a differentiated structure in the more greatly stressed area and have steep steps (210 mm) plus an active vertical surface for even more efficient separation. Guided by the generously sized surface provided by the stratified and self-lubricating lamellar supports, the control shafts allow the straw walkers to travel as much as 300 mm in height. We can easily affirm that use of a Laverda combine to shake straw and threshing tailings beats all comparison.
The task of a good preparation surface is to pre-select the grain in any condition so that it can be exposed to the action of the fan and sieves. On Laverda combines, this component is generously sized and equipped with tall longitudinal partitions that facilitate work on hillsides.
The grain pan has special sieves and an opposing action. These and the efficacious fan clean the crops in an excellent way with the utmost in performance and the minimum number of adjustments required. This is due to the high performance profile of the sieves which maintains the grain passage open at its maximum extent and ensures an ideal volume of air while preventing impurities from entering thanks to the vertical flap ends.
The generous way with which Laverda’s REV series combines have been sized is also reflected in the powerful NEF series IVECO engines with their “common rail” fuelling and 120 Amp alternator, ideal for these machines and available with an extensive supply of components and accessories. The simple transmission gets the most out of the power installed, thus the 225 REV model is fitted with a 220 HP engine while the REV 255 and REV 256 models have 255 HP engines.
The efficiency of the engines and systems is strictly correlated to that of the radiator cores, particularly for combines that work in hot and dusty places. Laverda’s designers have researched and built a generously sized, accessible radiator unit that’s equipped with an overturning rotating filter featuring forced circulation requiring the least possible maintenance and guaranteeing the utmost in efficiency.
Comfortable surroundings, visibility and ergonomics are the features that distinguish the “Elegance” cab with which the REV combines are provided. The cab is fitted with intuitive controls and everything the operator needs to use the combine in a rational way and achieve a good threshing process.
The operator can keep the combine under control at a glimpse thanks to the AGRITRONIC computer with which it is fitted. Three distinct modules with an equal number of displays keep him informed about the performances, the way the components are working, the harvesting progress (total area threshed and per unit of time) and about the way the cutting header adapts to the ground in the automatic mode thanks to the tried-and-tested Terra Control system.
When it comes to keeping an eye on the harvested crop, there’s also optimum visibility from the cab thanks to a generously sized window behind the driver’s seat and the door used for taking samples from the driving platform.
And speaking of visibility, the electrically controlled rear view mirrors with defrosting device make manoeuvres safe and convenient even when reversing.
Maintenance for Laverda’s combine harvesters has never been a chore but a chance to become familiar with one’s machine day by day. Thus a pleasure for users who can easily access the main components through the wide side doors. Even the most hidden parts are disclosed with just a few quick, easy manoeuvres.
Components made of wear-resistant metal assembled with bolts instead of being welded mean that parts can be periodically replaced without requiring complex and costly maintenance work.
Remember that over 80% of the components are made of hot-dip galvanized metal plate so it’s not surprising that you can often encounter Laverda combines over 30 years old and still going strong. Yet another confirmation of the advantages acquired by anyone who chooses a Laverda machine.
