MONOBLOCK rotor
Made from cold-rolled polygonal steel tube, to perform in the toughest working conditions: greater surface hardness, longitudinal rigidity and wear resistance. Its polygonal structure absorbs hammer impacts against the corners of the rotor and extends its service life. Forged steel brackets ensure exact positioning of the cutting elements and perfect balancing, even after replacing parts, with no vibration. And its bolted, replaceable shafts make maintenance easier and reduce downtime.
GIROSTOP
The innovative hammer-mounting system with GIROSTOP pins is the only one of its kind known on this type of machine. Thanks to its square anchoring head, the pin never turns in the hammer bracket welded onto the mulcher rotor. Because it doesn't turn, it never wears the bracket, so the brackets stay intact and their service life is guaranteed; and if the bracket shows no wear on its underside, this also guarantees reliable balancing of the hammer rotor. Because the pin is fixed, the hammer is forced to rotate on the pin. The pin head is flat and prevents twine or grass from tangling or catching. In addition, this locking system makes maintenance and hammer changes much easier and safer for the operator, since the pin nut can be removed with a single spanner.
550 POLSER and 550+ POLSER
Forestry rotor designed and built with Serrat polygonal-section technology. Floating hammer type that allows the hammer to rotate 360 degrees on its axis. The structural rigidity provided by this folded design prevents the rotor from deforming in the event of impacts, while achieving both rigidity and flexibility. The welds are placed in areas protected from ground contact to prevent premature wear. Internal plates are fitted to stiffen the shaft.
550 POLSER
Its polygonal shape makes it sturdier when the hammer recoils from impacts. Forged steel brackets, pinned in place with high-precision positioning for manufacture and assembly, ensuring perfect positioning of the cutting elements. Octagonal drive discs for better power transmission. Internal discs to give the rotor its structure.
PYOLTEK
Laser treatment on the hammer tip. On the wear zone, it extends service life, paying off both in hourly cost and in less downtime for maintenance.
SPLINTER
The main feature of the SPLINTER blade rotor is that it is made up of two spirals that distribute the load along the entire rotor, giving it very high rigidity; in addition, the blades are reversible, with two usable cutting edges. This rotor is intended for mulching pruning wood and brush clearing.
RHENDUEL
It is an innovative system of precision cutting for self-feeding mulchers. Its main advantage is that, thanks to its castellated blades and anvils, it achieves a fineness of mulching never before seen on this type of machine. It also reduces power requirements by 40%, something to bear in mind to save on fuel and investment. It has other advantages too: the mulched wood is incorporated into the soil in a way that is much faster and more effective, and within a short time it disappears from the ground of the plantation. In nut orchards, where harvesting is normally done with mechanical sweepers or pneumatic blowers, this type of machine is essential; otherwise the nuts are collected contaminated with the previous year's pruning wood, causing the grower losses and price deductions.
BRALACK
An exclusive Serrat Trituradoras design. It is built on two key factors. On the one hand, virtually total efficiency in picking up material, thanks to its helical mounting system. On the other, it achieves continuous, blockage-free feeding, which is absolutely essential on this type of machine when working windrows of large, thick pruning branches.
SYNKRODOS 600
It consists of a through input shaft and two crown wheels, which mesh with two pinion shafts, giving the same gearbox twice the power transmission capacity of conventional gearboxes. It has an oil cooling pump and an optional rear output for combined implements.
RAIL BOX
Automatic alignment system for the driveshaft between the tractor and the machine, relative to the lift position of the hydraulics. It articulates the gearbox so that the angles of the driveline joints are smaller during work.
HIDRAHELP
Hydraulic start-up system for machines with heavy rotors, PTO without soft start, and front PTO.
SEKURLAST
Special care in the study and design of the machine chassis at the inlet and outlet so that nothing is thrown towards the operator. Protecting both the operator and the tractor is a priority, so that neither is damaged by flying stones or pieces of wood.
FIXE TOP
Thanks to its distinctive fixing with ovals and recessed curves between the tooth and the holder, it provides absolutely reliable retention even in demanding soil mulching work. The bolts bear no load during work and only serve to hold the tooth against the holder. The arrangement of the teeth on the rotor keeps the bolt heads protected from erosion wear. The bolts have two spanner grips for when they are worn down by the ground.
