EQUUS 175N UN is the EQUUS 175N BH version with EQUUS 120 hydraulic arm with a grapple (size 0.35 as standard) and a clambunk with automatic clamping (optional). The grapple may also be in the version with a saw. Hydraulic arms are available in the following lengths: 6.1 m, 7.5 m (double telescope) and 9.5 m (double telescope). This is the best-selling version suitable for the majority of ordinary tasks where a high performance is required for a short time. The weight of the machine starts from c. 12,600 kg.

Meet the most efficient forestry skidder in its category, EQUUS 175N UN! Its main attributes are robustness and high working efficiency together with its rate of return. The machine is easy to operate and complies with the most demanding criteria of today's customers. It is equipped with a state-of-the-art hydrostat and a perfect cooling system. This high-perform forestry machine is capable of driving on roads to distances exceeding 100 km in a speed of 40 km/h. The lowest centre of gravity in its class makes this machine a perfect choice for work in the most demanding terrain.

Technical specifications of the EQUUS 175N UN



As one of the first forestry skidder manufacturers, EQUUS has installed the most advanced CUMMINS B45 engine that meets the requirements of the most demanding STAGE V emission class. With the power of 175 hp and the torque of 780 Nm, this direct-injection 4-cylinder engine delivers a performance comparable to larger and more expensive 6-cylinder engines, while being lighter, safer and more environmentally friendly.

Power: 129 kW @ 2200 rpm – 780 Nm @ 1500 rpm Stage V. At the moment the highest environmental standards and with certificates from producer of combustion engine.
Specifications: diesel, 4-stroke with direct fuel injection (Electronic Common Rail)
Nr.of cylinders: 4
Volume of cylinders: 4,5L
Fuel cleaning: water separator, fuel filter
Lubrication: pressurized, circulating with wet oil pan and oil filter
Cooling: coolant circulation through the water pump, termoregulator's valve
Placed: in connection with hydrogenerators
Handling: pedal with potentiometer



We have used a hydraulic motor concept with enlarged volume of 300 ccm and 45° swinging plate. The higher volume of the hydraulic motor decreases its maximum speed, the swinging plate increases its effectiveness. The 1st gear is suitable for the speed of 0–18 km per hour and for dragging at optimum engine speed, which is the most important contribution to transmission efficiency. The 2nd gear allows the skidder to travel easily over long distances without stopping at the speed of up to 40 km per hour. Hydraulics and certificate are both supplied by DANFOSS company.

Gearbox: Hydrostatic transmission with 3 automatic modes and 2 mechanical transmissions (turtle/rabbit) in a timing case, maximum speed of 40 km per hour forwards and backwards. The timing case allows for the disconnection of the rear axle 4x4 / 4x2.

Characteristics: The hydrostat is a low‑rpm and low‑pressure system. By increasing the volume of the hydraulic motor and decreasing the volume of the transmission, we achieved the optimum efficiency. With our skidder, you will be able to use roads without any fears of engine or hydraulic system overheating, with the speed of up to 40 km per hour! The behaviour of the hydrostatic transmission does not differ from a standard transmission – it does not slow down under load.



The cabin, which is an in-house production by EQUUS, offers the highest safety parameters. Not only does it meet the basic limits of the OPS, FOPS and ROPS standards, it even exceeds them. The cabin's position is as low as possible. It thus offers the most convenient way to get in and out of the cabin. Lighting is intelligently installed inside the body and therefore it allows, together with the use of high-quality glass, to eliminate the use of grille protectors. They might be fitted, however, if a customer requests so. The cabin has two doors and therefore it offers the possibility to mount on the skidder from both sides. The rear view is improved – there is a new glass panel in the roof of the cabin for better view when working with the hydraulic arm.

Characterictics: EQUUS (FOPS, ROPS, OPS) tilting safety cabin is equipped with Plastrans safety glass (with certificate A/M), suspension, two doors and a 315° rotating workstation (seat). The cabin complies with the strictest safety standards requiring the resistance of the cab to roll-over and breakage.

Equipment: Controlling – steering wheel with 2 joystics, Radio MP3 / USB, electricity 24V, 4 working lights, heating and the sun visor.



- Rigid axle with wet multi-plate brakes and handbrake for all four wheels and 100% differential lock. Oversized 17 t axles, which are comparable by their parameters to axles installed on machines of higher category (6-cylinder machines).


Material and design: S690QL - high-strength steel 700 N / mm2,

Frame construction: When using tyres 23.1-26 (600mm wide) is the max. width 2450 mm - enables the machine to be loaded and transported easily with a conventional truck.

Combination of axial bearing and vertical pin for oscillation the frame by 15 ° and bending the frame by 45 °.

The front share and rear shield have a width of 2200 mm.


Winch with spur gear in the gearbox offers 2 drums with large rope capacity.
In the standard version we offer a pulling force of 2 x 11 t.

Speed: two-stage 1.35 m / s - 0.65 m / s
Rope capacity: max. 2x 115 m, Ø14 mm

Hydraulic system

Hydraulic system

Working pump: 100 cm3 (220l @ 2200)

Pressure: max. Pressure 220 bar for all hydraulic components (except PTO)

Oil volume: 110 l tank + components

Hydraulic arm

As standard, we offer EQUUS 120 arm with the length of 6.1 m to our customers. The arm offers an above-standard lifting torque of 120 kN. The hydraulic arm can be folded in a horizontal position which allows an easy transport of EQUUS 175N UN wheeled machine using an ordinary truck. The robust construction allows for trouble-free handling of timber, not only its loading but also dragging.

For better reach, we can offer a 7.5 m arm as well, see the Accessories section. As standard, we provide our customers with 035 version grapple manufactured by Gripen. With an area of 0.35 m2 and the maximum opening of 1880 mm, it offers an permissible load of up to 5000 kg. All this comes with the weight of 255 kg only.
