<strong>EXCAVATOR</strong> <strong>MOUNTED</strong> <strong>MULCHERS</strong>The excavator mounted mulchers come with hydraulic drive andhave been made specifically for being mounted on excavatorarms.With the combination excavator + mulcher it is possible to reachremote and difficult to access areas, uneven grounds, marshlandor steep slopes. The SEPPI mulchers for excavators are greattools for greenspace maintenance as well as for maintaining powerlines, roadsides and riverbanks. When preparing constructionsites, they help eliminating stumps, trunks and all other vegetation.Excavator mounted mulchers by SEPPI M.:› for excavators from 3 to 35 tons› for mulching grass, brush and wood up to 5, 7, 20 and40 cm in diameterexcavator mounted mulchers for:1 – greenspace maintenanceH-SMLH-SMO-B2 – light forestry mulchersMINI BMSBMS-LBMS-F3 – heavy duty forestry mulchersBMSSUPER BMSHow to work with an excavator mountedmulcher by SEPPI M.?Excavator mounted mulchers are great machines withwhich to maintain difficult to access greenspace.

INSTALLATIONThe installation of hydraulic mulchers on an excavator requires some technicalskills and knowledge. This page gives most information needed for the set-up andinstallation of your machine. Nevertheless, we recommend to refer to the user manualfor a detailed description and safety procedures.Attachment interfaceMulchers for excavators can be supplied with a universal interface thatcan accept different attachment plates, depending on the excavatorused. For details or drawings of the universal interface please ask yourSEPPI dealer.WeightThe excavator must be able to carry the weight of the mulcher as indicatedon the ID plate. For many excavators a good approximation is:excavator weight ≥ 15 x mulcher weightPressureTo avoid overheating the circuits the system pressure should neverexceed the indicated maximum pressure. However, all hydraulic motorsdelivered by SEPPI are equipped with top mounted pressure relievevalves set to the right pressure.Case drain pressureAll motors delivered by SEPPI are high performance piston motorswhich need a case drain connection to the tank. The case drainpressure must never exceed the values specified in the table below!modelH-SML, H-SMO-B, BMS-L, MINI BMSMINI BMS, BMS-F, BMS, SUPER BMSdrainage pressuremax. 1.5 bar[21 PSI]max. 5 bar[70 PSI]FlowThe efficiency of the mulcher depends mostly on the speed of the rotor.The speed depends on the flow available from the prime mover and onthe size of the hydraulic motors installed.Upon demand, your SEPPI dealer can help you to define which of theavailable motors will best fit the hydraulic circuit on your prime mover orcompact loader.Hydraulic hoses and connectionsTo install the machine on the prime mover or compact loader, thehydraulic pipes and hoses have to be made on site. For the diameter ofthe hoses take the following table as a reference:pipes andhoses25-50 l/min[7-13US gal/min]recommended diameter100-200 l/min[26-53US gal/min]50-100 l/min[13-26US gal/min]200-400 l/min[53-106US gal/min]400-800 l/min[106-211US gal/min]pressure (P) ¾ ” 1 ” 1 ½ ” 2 ½ ” 2 x 2 ½ ”return (T) ¾ “ 1 ” 1 ½ ” 2 ½ “ 2 x 2 ½ “drainage (D) ½ ” ¾ ” 1 “ 1 “ 1 “Hydraulic hood controlOn forestry mulchers the hood can be opened or closed hydraulically.This requires an additional directional valve. On request this valve canbe delivered by SEPPI.CavitationCavitation happens when the motor runs “dry”, e.g. the hydraulic flowis interrupted but the mulcher continues to rotate. To prevent damagesto the motor due to cavitation all motors are equipped with an “anticavitation”valve mounted on top.Open or closed loopAll hydraulic SEPPI mulchers can be installed on either open or closedloop systems. Closed loop circuits sometimes need extra flushingvalves for cooling. In that case please contact your SEPPI dealer or theSEPPI technical department.SafetySEPPI M. requests to have ROPS/ FOPS standard protected cabinsand to follow all the safety instructions listed in the user manual.Direction of the rotorThe direction is defined on each model.Some mulchers can optionally be fitted with an additional valve whichallows the motor to run in both directions. This will reverse the rotationof the rotor, so swinging hammer rotors will cut in either direction withsuitable extra guarding.10
