PRO-LONGER GII hedge and grass cutter

To adapt to all types of jobs, the universal rotor is available in the conventional length of 1.20 m and also in the 1.60 m MAXI WIDTH. In the first configuration, the rotor is fitted with 60 KUHN broad Y-flails assembled on a 14 mm shackle. This rotor is designed for cutting and trimming of scrub featuring a maximum diameter of 3 cm.

The 1.60 m MAXI WIDTH equipment is designed for mowing and cutting grass and features a set of 42 spoon flails on a 14 mm shackle. It also becomes possible to use this head in "brushcutting" mode thanks to the retractable front-end cover. Wide hedges can be trimmed in a single run.

KUHN broad flail: prefer the original! You will be glad you chose KUHN flails! The exclusive KUHN broad flails are 10% heavier than those present on the common wear parts market.

The XTREM sensor roller is perfectly watertight in all working conditions. Both ends are equipped with double taper roller bearings. The assembly is 100% sealed:

• On the lug mounting side, by labyrinth seal O-rings and face seals on a film of oil,
• Sensor roller side, by a plug.

For quicker set-up of the different flail heads (rotor, saw, cutter bar, etc.) the PRO-LONGER GII models feature a semi-automatic tool hitching system. The hitching frame allows for accurate positioning of the flail head on the arm.

The PRO-LONGER GII model design was rewarded by the highly prestigious SWEDISH STEEL PRIZE. This international prize is awarded by SSAB and is open to all machine manufacturing companies (farm machinery, public works and industrial machines) using high strength steels in their products. The arm has a reconstituted structure. This design has numerous benefits, including the varying thickness of the steel and the addition of internal stiffeners on the different points of the arm subject to high levels of stress.

Very high yield, industrial-grade steels provide the arms in the PRO-LONGER GII range with twice as much strength and flexibility as a standard tubular structure. Very high yield strength steel is a shape memory alloy. Depending on the load level, the steel returns to its original form. It is thus less subject to breakage under repeated loads. Ageing, resulting in the breaking point, is delayed.

All the machine joints are protected against wear by greased-for-life cell-type bushes. Rotational shaft movement is prevented to avoid premature wear.

With the cooling capacity of the imposing fan on the PRO-LONGER GII models sustained work can be kept up all day long.

• Double exchanger: the first one cools the hydraulic system of the two pumps and the second one cools the motor drain,
• Equipped with a flow reversing system to remove dust from the radiator,
• 21 kW power, thus 30% of additional exchange capacity compared to the equivalent models on the market,
• Low temperature trigger point to prevent thermal runaway of the hydraulic system,
• Position on the left side rather than on the rear. The fan intakes a lot less dust stirred up by the tractor's wheel.

The design of the PRO-LONGER GII 5183 P and 5683 P models is characterised by a straight arm with compass movement.

With a 5.10 m and 5.60 m horizontal reach, these two hedge and grass cutters are perfectly adapted for farm use or professional roadside maintenance in addition to a fleet of leading or telescopic arm machines. These two models feature all the advantages of the PRO-LONGER GII range: EP (4-function electric proportional) control, the pivot with a 116° slew angle, patented four-sprocket mechanical drive flail head, etc.

Drive it like an automatic gearbox!

These two PRO-LONGER GIIs have a horizontal reach of 5.70 m and feature an 80 hp rotor. They are fitted with an additional OPTIview semi-leading arm and parallelogram kinematics.

For "parallelogram" kinematics the main and outer booms are joined by a link. The operator controls all the arm movements with the machine joystick. Only one function on the joystick is required to move the main boom and outer boom.

With their parallelogram the PRO-LONGER GII 5783 SPA and 6183 SPA model control system is intuitive right from the start. Drivers shall rediscover performance associated to unbeatable driving comfort.

PRO-LONGER GII models with the MAXIview leading arm offer the best lateral visibility of the entire range.

The "leading" arm positions the mower unit (leading line of the cutting tool) 2,517 mm from the median plane of the main boom (standard dimensions according to NF EN 15436-1). For the driver, this puts it in the same field of vision as the front part of the tractor and, as a result, obstacles can be anticipated more easily:

• Improved driving comfort,
• Easier to avoid the obstacles: extended machine service life,
• Improved work performance and productivity,
• Greater driving comfort combined with a front-end tool, etc.

The MAXIview leading arm has a reconstituted structure. This allows to select high-grade steel grades (very high yield strength) and add internal stiffeners in the areas submitted to high stress levels. The assembly is more resistant and more flexible than a tubular structure.

The LPA model features the parallelogram system in addition to the MAXIview function. The machine is easy to handle with one single control to operate both arms.

The e-LPA model features electronic parallelogram kinematics. It's exactly what you need for driving comfort! This technology works by using the arm's hydraulic cylinders, while also feeding information to the electronic control system to make use of the automated functions. These automated functions ensure that the cutting head remains set at the same angle throughout the cutting operation, even as the hydraulic arm is extended or retracted. A single movement on the joystick activates two arm movements for precision and easy handling! When trimming hedges vertically or horizontally, the parallel movements of the cutting head guarantee quality results and unbeatable speed.

The extra height you needed!
To adapt to the different types of works, certain professionals need long reaches. These 2 models have a respective horizontal reach of 6.10 m and 7.40 m.

These PRO-LONGER GII models feature 1.00 and 1.50 m telescopes, respectively. The male tube is guided with 16 ERTALON pads positioned inside the outer boom. Eight of these pads are fixed and eight can be adjusted. Over time, it becomes easier to compensate for clearance by adjusting the position thereof. This assembly is now the most simple and durable design offering long-term reliability.

For easy maintenance, the telescope is driven by a cylinder positioned above the arm. It is fully enclosed in a protective casing. The hydraulic lines use the "100% hose" solution. This type of assembly is less likely to be damaged by falling plant debris than rigid piping and allows for quick servicing. Hoses are routed inside the telescopic boom. They are guided by 4 rollers to prevent friction wear.

The e-TPA models have electronic parallelogram kinematics. It's exactly what you need for driving comfort! This technology works by using the arm's hydraulic cylinders, while also feeding information to the electronic control system to make use of the automated functions. These automated functions ensure that the cutting head remains set at the same angle throughout the cutting operation, even as the hydraulic arm is extended or retracted.
