Heads for Hydraulic Arms
Choosing the right equipment is the key to staying ahead of the competition and delivering projects on time. Our catalog includes machines that turn a standard tractor or excavator into a versatile work center. For companies maintaining road shoulders and drainage ditches, we have prepared reliable boom mowers that offer impressive arm reach and precise control. With them, work on steep embankments becomes safer and significantly faster, reducing operating costs on every kilometer of road.
Solutions for special tasks on every terrain
Where punching power and resistance to harsh conditions matter, our flail mowers are irreplaceable. They are designed for intensive shredding of dense grass, bushes and self-seeded plants over large green areas. If your work involves construction equipment, an excavator cutting head is the ideal choice. It allows efficient use of the carrier’s hydraulics for maintenance of slopes and watercourses, with exceptional durability of the cutting elements.
Can stumps be removed effectively without damaging the terrain?
Our offer is supplemented by specialized tools for land reclamation and forestry work. Each stump grinder we offer precisely removes post-felling residues, preparing the ground for new plantings or construction investments. Instead of using heavy equipment to pull out stumps, choose grinding — less invasive and significantly more economical.
By choosing Rolmex products, you receive technical support and access to machines designed for maximum daily efficiency.
Cutting heads for hydraulic boom mowers — interchangeable working attachments that adapt your machine to specific tasks. Choose from grass-cutting heads, brush cutters and specialty tools to extend the capabilities of your Rolmex boom mower.

Questions and answers
Which head can cut branches thicker than 10 cm?
According to the product tables, the TGR-155 guillotine cuts material up to 155 mm, the TR155, TR165 and TR200 saws up to 150 mm and the TR130 and TR180 saws up to 120 mm.
The Ragnar100 mulching head with the RAGNAR360 rotor handles branches up to 120 mm, and the GH head with H360 FORESTAL hammers material up to 10–11 cm. To work with the TGR-155 guillotine, the tractor must have a crawler gear.
What oil flow must the arm and tractor provide for the working heads?
Minimum flow given in the tables: SP90 — 110 l/min, KD120 — 110 l/min, PR80 — 120 l/min at 200 bar or 100 l/min at 300 bar, GS-70 — 90–120 l/min, WK-80 — 20–120 l/min (adjustable), SWB100H — 30/60 l/min, SWB130HD — 45/90 l/min.
What is the difference between the heavy-duty GH head and the compact GHL125?
The GH-120 and GH-130 are 120 cm and 130 cm wide and weigh 270–340 kg and 280–350 kg; depending on the shaft, they cut material up to 5 cm (Y/YI blades), 6 cm (T6 hammers) or 10–11 cm (H360 FORESTAL hammers).
The GHL125 is 1.25 m wide, weighs 270 kg and has a hydraulic motor power of 45 HP. The KRL series description gives the minimum shaft power: 45 HP for the GHL125 and 54 HP for the GH120.
Which heads are used for winter work?
The SWB rotary snow thrower (working width 1000 mm on the SWB100H and 1300 mm on the SWB130HD) removes compacted snow and ice. The ZMX160 sweeper (1.6 m, brush Ø 40 cm) removes fresh snow from pavements at 0.5–1 km/h. The GS-70 brush can also be used as a snow sweeper.
Do ROLMEX heads fit arms from other manufacturers?
The product pages state this directly for the KD120 (boom mowers from various manufacturers), the WK-80 (Rolmex KR booms and boom mowers from other manufacturers) and the SWB (ROLMEX KR520, KR600Z, KVT and KB-series arms and arms from other manufacturers).
The same applies to the TR saws (boom mowers and construction machines of various brands) and the GS-70 (various hydraulic arms). For the other heads, the product pages do not specify this.
