mod. XJ structure that can be hydraulically lowered
Both the Xj and Xjm range of RM hose-reel irrigation machines feature a structure that can be hydraulically lowered. Therefore, two positions are determined: on wheels to allow its transfer on road or standing on the ground during work phase. The latter position allows the hose to be unwound in any direction - 360° movement - without having to reposition it again. Moreover, the base resting on the ground gives the machinery a high anchoring which is very useful with long hoses with a large diameter.
The transverse width of the highest reel allows to considerably lower the overall height of RM machines and their barycentre, thus making them among the stablest ones on the market. Monolithic RM frames are free from any screwed structural elements, manufactured in a single block and hot-dip galvanized, designed through a three-dimensional calculation system. All models of the XJ and XJM series are equipped with barycentric axle on wheels, thus rendering their transport easy and safe under any running condition.
Such setting - obtained by moving the wheels towards the bar – translates into a less load on tractor hitch system, thus making its use easier even with small-sized vehicles. Moreover, all models have rear telescopic anchoring brackets that can be individually enabled on the two sides of the machine.

ENERGY EFFICIENCY WITH CONSUMPTION REDUCTION, thanks to RM Turbo-Reducers
The energy required to rewind the hose is the decisive element in the economy of the self-propelled irrigation machines: RM Turbo-Reducer Unit with in-built water By-Pass and four-speed gearbox drastically reduces pressure losses during the irrigation phase, thus ensuring money saving determined by less energy consumption.
The design of the turbine impeller is the result of a cutting edge aerodynamic calculation which allowed reaching an extraordinary channelled flow of the liquid without any turbulence, thus ensuring the operation with a minimum pressure of 1.5 bar at machine inlet. The quality of the Turbo-Reducer Unit is obtained by using all the movable internal parts in stainless steel, such as all bearings (including the ones of the turbine axle) in class A dipped in oil bath.
The system includes a built-in automatic brake that engages during hose unwinding and disengages during rewinding. Moreover, at the end of rewind the Turbo-Reducer positions the “Operation-Stop” lever to the correct position for the following hose unwind.
The exclusive RM Power Save™ system allows for a practical, quick speed change even during the normal hose rewind with water under pressure, thus immediately reducing the turbine rotational speed without having to act on the electronic programmer controls.
RM Turbo-Reducer Unit does not require any periodic maintenance. Moreover, at the end of sprinkling process every liquid residue is automatically ejected from the turbine body.
ACCURACY IN ROTATION, by means of chain drive
Another remarkable characteristic of RM hose-reel irrigation machines: starting from the 581 Gx Evo model the drive between turbo-reducer and reel is manufactured with high-tensile strength ARNOLD STOLZEMBERG® chain with extruded rollers and without extension.
Moreover, by using the adjustable toothing (another exclusive of RM) located in the outer reel diameter, a very high transmission gear ratio is created between the wheel and turbo-reduction gear in order to drastically reduce the energy absorption for rewind as well as the turning moment in the reduction gear output shaft, thus preserving its duration in time.
In the MAJOR EVO and MAGNUM (optional mod. 900) models drive chains are located on both reel sides in order to also cancel the torque effect of reel.
REEL AXLE: the best technology available in the market
Reel mass with its hose in polyethylene wound and filled with water reaches 80% of machine weight.
Supports on which reel rotates are subject to very high loads, thus generating high frictions, which must be minimized in order to reduce the effort required for the movement.
RM reel axle is:
This technology – an exclusive of all RM models – is applied to the whole range, including the cheapest models.
INTUITIVE OPERATION by means of RM RainMaster 2.6 programmers
RM electronic programmers were designed to be perfectly built into the irrigation machine. They are simply to use and feature an intuitive, multilingual display; it can be easily bypassed without interrupting the machine irrigation cycle in order to switch from automatic to manual operation. Electromechanical drain and/or shut-off valves, GSM modem, solar panel for battery and anemometer recharge are available as optionals. The optional additional gun of rewind end can be controlled as well.
AN EXCEPTIONAL GRIP by means of height-adjustable towing hitch eye
All the XJ and XJM models are fitted with the towing hitch eye whose height can be adjusted through simple gudgeon pins.
MULTI-SECTION TECHNOLOGY for an indestructible reel structure
Starting from the 581Gx model the reel resorts to the multi-section ribbed technology fitted with sides completely made up of high strength DOMEX 420™ sheet with yield load to 420 kg/mm2, made up of wedges precut by means of HD Laser system and then assembled through robotic welding. This leads to a high resistance to bending stress, despite the reel lightness, and to an increase by 300% of the PE hose supporting surface on reel sides - a remarkable advantage compared to the outdated system of side tubular tires. The internal ferrule is made up of calendered flat sheet, which helps preserve, then extend the duration of the polyethylene hose in the course of time.
The 800, 840, 900 models feature the “tapering profile” side reel section, so that all side bends can be effectively counteracted even during the most difficult rewinds. Sections of each side were designed to be fully and thoroughly coated by the double-layer painting treatment even in the most internal parts. In that way steel does not deteriorate in the boxed or hidden parts. A side white segment allows checking the regular reel rotation even from a great distance.
MAXIMUM STABILITY AND DIRECTIONALITY UNDER ANY CONDITION by means of RM rain gun trolleys
All sprinkler trolleys are available in the two- or four-tyred wheel version or made up of cast iron with directional crests. The latter ones - expressly conceived for the rain gun trolleys of RM hose-reel irrigation machines – increase trolley stability, improve its orientation and distribute the weight where necessary. Both wheel types can be replaced swiftly and fitted with hubs with tapering bearings and lubricator. The whole trolley structure is hot-dipped galvanized, thus ensuring an outstanding lifespan and much attention was paid to adjustments, which are very user-friendly and can be locked by means of gudgeon pins. Even all the critical problems connected to the rewind phase were thoroughly analyzed, designing the shape of the middle hose next to the PE hose in order to cancel any entanglement with crops during the rewind phase.
HIGHER RESISTANCE TO AGING thanks to RM painting cycle
A preventive pickling treatment is performed on the painted parts of all RM machines as well as a following painting process through a double-layer electrostatic system – which ensures a coating even in the most hidden machine parts – with highly eco-friendly water-based paints and primer. Each cycle is accompanied by an in-oven stabilization treatment at 60°C, thus obtaining surfaces which are highly resistant to corrosion and especially to UV rays.
DISTRIBUTION ALWAYS PERFECT thanks to the exclusive VertiLift™ lifting system
All the XJ and XJM line models of RM hose-reel irrigation machines are fitted with the automatic “VertiLift™” lift of trolley during sprinkling end phase. The exclusive progressive compass system holds the rain gun in a vertical position, thus making the sprinkling action effective until trolley has been lifted from the ground, and correcting any drop between machine and rain gun trolley.
DOUBLE AXLE WITH ASYMMETRICAL ROCKER ARM less effort on towing on every kind of ground
All the machines of the XJ and XJM series fitted with double axle with isodiametric wheels feature the asymmetrical rocker arm. This solution allows for a remarkable reduction in towing on rough soils, which – accompanied by a reduced side overall dimensions – also ensures a better distribution of weight during the steering phase, thus making the machine handier than the axle. Machines can be fitted with different size tyres, among which those having a “Big Size” type big section. Nitrogen-charged shock-absorbers – supplied as standard starting from the 900 model – improve the absorption ground unevenness and reduce bar pitching during towing.
GUARANTEE OF RELIABILITY, as machines are tested one by one.
All RM machines are thoroughly tested before being shipped to the customer. They undergo both mechanical tests – to check their operation – and hydraulic tests by means of pressure water at 12 bar to check the accuracy of joints and connections and the resistance of various components to water pressure.

|RM manufactures its machinery and equipment in compliance with the environmental protection. They use raw materials coming from eco-friendly, certified cycles; they use exclusively water-based paints; they implement technologies in order to reduce energy consumptions. Those are some of the principles determining the technical choices for RM hose-reel irrigation machines, believing that only an attentive approach to those themes – aimed at reducing pollutant emissions – makes the external environment cleaner and the work healthier for workers.|
Very high-quality POLYETHYLENE HOSE with differentiated thickness
All RM hose-reel irrigation machines feature the medium density polyethylene hose (PEMD) with differentiated thickness starting from ø 90 included; the highest thickness near the reel allows for a better accuracy on rewind and a less ovalisation due to hose bending.
