Multi-Master 123 4E T Kuhn Multi-Master 123 4E T Specifications & Technical Data (2014—2026)

Designed for mid-range tractor horsepowers

The MASTER 123 ploughs have been designed to meet your requirements for a versatile machine which is both easy to use and strong enough to meet the demands of today’s average sized farm. This plough range is available from 3 to 6 furrows in both MULTI-MASTER and VARI-MASTER versions and in either traction bolt or non-stop hydraulic. Its technical characteristics and different equipment options make these ploughs adaptable to all situations.

Designed for intensive use

The MASTER 153 ploughs have been designed to meet the same demands as the 123 range but for more intensive use, more difficult work conditions and higher horsepower tractors. The 153 ploughs are available from 3 to 6 furrows in MULTI-MASTER and VARI-MASTER in either traction bolt or non-stop hydraulic. The strength, simplicity and different options available make the plough fully adaptable to your needs. This range also features the possibility to assemble diamond bodies, particularly useful where wide tyres are fitted to the tractor.

Wide Furrow-Bottom

Allows the use of wide tractor tyres to increase traction and reduce compaction, while also reducing wear of tyre walls.

Traction Bolt Leg Protection

Abrupt breakage of the 16mm traction bolt following a force at the plough point in excess of 3000kg avoids the risk of too frequent a breakage. The bolt runs in the direction of the line of force, contrary to the conventional scissor bolt method where the bolt runs across the line of force. Due to these “in-line” forces, the bolt support never deforms and never becomes rounded with use. It is impossible for the bolt to become trapped inside following a breakage. Once a force in excess of 3000kg is met at the furrow point, the bolt breaks along its length and simply falls away for quick and easy replacement.

Press arms with hydraulic release

Available for the complete plough range, the arm allows the use of a furrow press with easy hooking up and hydraulic push-off. On the pick-up hook part of the arm, where there is most risk of damage, all grease nipples and hydraulic hoses are protected inside the structure of the head. The arm folds up conveniently for subsequent transport.

Easy adaptation for all tractor inter-tyre distances

Depending on tractor type, the plough is pre-set for three ranges of tyre spacing: 1.15m-1.35m, 1.30m-1.50m and >1.45m. This adjustment is required only once for your tractor and ensures optimum use of the engine power available.

Useful Advantages of a Variable Width Plough

Instant adaptation to available traction.Time savings and reduced fuel consumption.Holding of a good working speed on steep slopes.Ability to cope with different levels of trash.Neat finish to the field.Avoiding obstacles and tidying up of difficult unploughed areas.

N body

Helicoidal cylindrical semi-digger. 15 to 30cm ploughing depth. Highly versatile body. Cylindrical at front, helicoidal at rear. Low draft, ensures a partly broken furrow, with excellent trash burial.

L wide helical h4 body (also available in plastic)

The capacity, long helical mouldboard, Scandinavian type, giving well formed ploughing to a depth of 30cm. Especially suited to heavy and damp clays. (H6 gives ploughing depth to 35cm).

Vp slatted body

Mouldboard composed of independent and interchangeable slats. Gives a reduction of traction force, due to a lower mouldboard surface area. Easy maintenance.

Disc coulters

Discs have a diameter of 500mm plain or notched with the added choice on the traction bolt models of a 600mm disc. The disc serves to cut the furrow wall in front of the plough body giving a cleaner finish and improving trash incorporation.

Forged and Heat Treated One Piece Main Link

Designed for strength (270 or 330 mm height) and long life the main link is assembled with either bronze or steel bushes depending on the model of plough.

Exclusive to Kuhn

The whole variable width linkage system is enclosed in the plough structure giving maximum protection from water, dust and possible shocks.All moving pivot points are chromed, prevented from rotating and assembled with wearing bushes: no risk of jamming and very low maintenance.

Main Beam

The main beam (either 120mm or 150mm section) is supported by a side mounted triangular reinforcement welded along the length of the front section. This increases the strength of the beam in the zone of most stress and gives substantial advantages when compared to a conventional plough design.

Mouldboards with Unequal Layer Triplex Steel

Kuhn mouldboards are made of unequal layer Triplex steel. The thickness of the wearing surface is increased to 3.3mm - an exclusive feature.

Plough Bodies Designed to Reduce Wearing Cost

Shares are forged with a force of 5500 tonnes ensuring: excellent wear resistance, self-sharpening profile due to the grain in the steel resulting from the forging process.

Super Marathon

Special heat treated forged steel fitted with a tungsten carbide tip. High wear resistance. Four to five times the life of a traditional share point. A sharp working edge is maintained for excellent ground penetration.

Working width adjustments on the vari-master 123

12” to 18” in 90cm point to point and 12” to 20” in 102cm point to point. The working width is changed hydraulically from the tractor cab. The correction of the front furrow and plough aligning settings are carried out automatically as the width changes. For plough turnover, the plough bodies fold up automatically to their narrowest width for the maximum possible ground clearance. After turnover, the plough returns to the memorised working width.

Multiple Working Widths on the Multi-Master 153

A change in working width to 14", 16" or 18" whether in traction bolt or non-stop hydraulic is quickly carried out by pivoting the plough leg support on the beam and placing the bolt in the corresponding width setting hole.

Combined Front Furrow Width/Angling

According to the tractor linkages and/or the ground conditions, the front furrow width is adjusted to its optimum setting. The parallelogram obtained by the layout of the two linkages means that any adjustment in front furrow width automatically adjusts the angling of the plough so that the tractor always pulls in perfect line. Adjustments are quickly carried out by simply turning the turnbuckle adjuster or by activating the hydraulic cylinder (optional). One adjustment is sufficient, unlike conventional systems where the front furrow width and the plough alignment are separated. With the conventional system, as one adjustment interacts with the other, several successive adjustments are necessary.

Beam Folding Cylinder for the Multi-Master

Hydraulic beam folding cylinder (optional) advised for 4 and 5 furrow models. The link is fitted as standard for changes in working width.

Auto Reset Plough Leg Protection (Non-Stop Hydraulic)

Designed for stony and/or heavy conditions, the Non-Stop Hydraulic (NSH) system allows continuous ploughing with the plough legs automatically folding out of work upon hitting an obstacle and immediately returning into work again once the obstacle is passed. There is no need to get out of the tractor or replace bolts. The system also acts as an excellent shock absorber when working in pebbly or flinty ground, absorbing all the vibration, increasing the life of the plough and enhancing comfort for the driver. VARIBAR system: An optional system allowing instant control from the tractor cab of the NSH pressure at the share point - either with or without Maxibar. MAXIBAR system: The Maxibar option allows the pressure at the share point to be increased, giving an adjustment range of 600 to 2500kg while conserving the flexibility of the system. This option is particularly useful in heavy compacted ground.

2 - A Unique Concept

The basic concept of the hydraulic non-stop plough leg safety system gives a rapid break-away when an obstacle is met, yet an increase in pressure thereafter brings the body quickly and firmly back into work.

Benefits of the NSH System

Long life and reliability - hydraulic technology is more reliable with no wear or friction and fewer moving parts (just one articulation point and two moving parts per leg). Weight saving - compared to a mechanical auto reset system, the NSH system is 25kg lighter per leg. Ease of use - the pressure at the share point can be quickly adjusted from 600 to 1300kg by simply inflating or deflating the accumulator mounted on the headstock. Excellent performance - plough leg resetting is quick and positive once the obstacle is passed with no “drumming” of the plough bodies in work. Compactness - the NSH tie rod is located inside the plough leg structure and the hydraulic cylinder is incorporated into the leg profile for the maximum possible clearance and minimum obstruction to trash and vegetation. Exceptional obstacle clearance - the share point can lift 60cm vertically out of work and 20cm sideways.

Heavy Duty Plough Leg Articulation and Tie Rod

All pressure points receive a specific heat treatment process. With just one articulation point, all the forces put through the plough leg are transmitted in a straight line through a one piece forged and heat treated tie.

Transport wheel with suspension

The plough can be transported on the road in complete safety thanks to a 540mm diameter transport wheel equipped with its own suspension system, ensuring protection for the plough and tractor from possible transport shocks. The wheel can be swung into the transport position in a single movement by pulling on the locking pin.

Independent, easy to adjust skimmers

Each skimmer is totally independent left from right and is firmly held in a sheath like support. The skimmers are shear bolt protected and are adjustable in three directions: Forwards and backwards - with a choice of three positions the sheath bolts to the leg support via countersunk holes to avoid any risk of free play. Up and down - rapid and precise height adjustment (20cm of adjustment) also with countersunk holes in the skimmer leg for easy locking of the leg at the desired height. Side to side - for correct adjustment in relation to the disc coulter (where fitted).

Hydraulically hd tronic adjusted depth wheel

Ø 760, 370mm width. Outstanding carrying capacity in difficult conditions. Easier rolling owing to the large diameter and agricultural thread of the wheel.
