Multi-pur­pose site prep ma­chine

Australian Forests and Timber - - BIO -

CATER­PIL­LAR MAN­U­FAC­TURES a pow­er­ful, mul­ti­pur­pose wheeled ma­chine for mulching or cut­ting veg­e­ta­tion that can be used for var­i­ous land man­age­ment ap­pli­ca­tions. The Cat® 586C Site Prep Trac­tor may be used for pro­cess­ing trees and brushy veg­e­ta­tion into mulch or, de­pend­ing on the at­tach­ment, cut­ting the stems.

Ap­pli­ca­tions in­clude res­i­den­tial and com­mer­cial de­vel­op­ment, land man­age­ment, right-of-way con­struc­tion and main­te­nance, wet­lands and wildlife habi­tat man­age­ment, plan­ta­tion recla­ma­tion and man­age­ment, and clear­ing for flood con­trol and fire­breaks.

“Any­one who needs an ef­fec­tive, cost-ef­fi­cient ma­chine for land man­age­ment or any other high de­mand ap­pli­ca­tion should strongly con­sider the Cat 586C Site Prep Trac­tor,” said Matt McDon­ald, a Cater­pil­lar pro­duc­tion ap­pli­ca­tion spe­cial­ist.

The Cat 586C Site Prep Trac­tor is pow­ered by the C9 ACERT™ 261 kW (350 hp) en­gine, mounted in the rear so the weight of the trac­tor is dis­trib­uted evenly over the axles for rock-solid sta­bil­ity.

Cater­pil­lar of­fers two at­tach­ments for the ma­chine, the Cat HM825 Mulcher, which can tackle trees up to 40.6 cm (16 inches) in di­am­e­ter, and the Cat BR624 Brush­cut­ter, ca­pa­ble of cut­ting through sin­gle stems up to 20 cm (8 inches). Both are avail­able from the fac­tory and sup­ported by Cat deal­ers.

The Cat HM825 Mulcher is es­sen­tially a pow­er­ful grind­ing tool. It can process veg­e­ta­tion into mulch at rates rang­ing from 1/4-acre per hour to nearly 3 acres per hour, de­pend­ing on the de­sired end prod­uct, veg­e­ta­tion and den­sity, ground con­di­tions, and op­er­a­tor ex­pe­ri­ence. Ap­pli­ca­tions in­clude vir­tu­ally any need for re­mov­ing veg­e­ta­tion - from brushy ma­te­rial to trees - and pro­cess­ing it into mulch. Ex­am­ples in­clude cre­at­ing ac­cess trails and roads, main­tain­ing golf cour­ses, and man­ag­ing wildlife habi­tat and hunt­ing land and other land­scapes.

“The real heart of the Cat 586C is the Pow­erDirect Plus sys­tem,” said McDon­ald. “That al­lows us to over-size all the dif­fer­ent hy­draulic cir­cuits.”

The Pow­erDirect Plus sys­tem mon­i­tors what the at­tach­ment is de­mand­ing, what the op­er­a­tor is com­mand­ing the ma­chine to do, and the avail­able power from the en­gine. The sys­tem puts power where it is needed to max­i­mize pro­duc­tiv­ity while op­ti­miz­ing en­gine per­for­mance, fuel ef­fi­ciency and dura­bil­ity by main­tain­ing a con­sis­tent load on the en­gine.

The sys­tem is an im­por­tant fea­ture, noted McDon­ald, be­cause the mulching tool prob­a­bly has the high­est power re­quire­ment of any tool in the forestry in­dus­try. For ex­am­ple, a hy­draulic pump pow­er­ing a har­vester disc saw may run at about 155 litres (41 gal­lons) per minute. The Cat mulching tool gets about 378 litres (100 gal­lons) per minute and also op­er­ates at a higher pres­sure than saw head pumps.

De­bris man­age­ment is a key con­sid­er­a­tion in site prep ma­chines be­cause they gen­er­ate so much pul­ver­ized wood ma­te­rial, dirt and dust. The Cat 586C Site Prep Trac­tor de­sign fea­tures pres­sur­ized com­part­ments that keep de­bris out of the rear-mounted en­gine, hy­draulics, and cool­ing sys­tem. The pres­sur­iza­tion re­duces down­time and main­te­nance - time spent blow­ing out de­bris - and en­hances per­for­mance. Plus, the pres­sur­ized air flow keeps elec­tron­ics, sen­sors and other com­po­nents cool.

“We’ve got some unique things that are in­te­grated with the air clean­ing sys­tem that dif­fer­en­ti­ate us,” added McDon­ald. Be­yond the lo­ca­tion of the en­gine air in­take, a dust ejec­tor chute is in­te­grated into the pre­cleaner, which elim­i­nates re­cy­cling dust and de­bris into the pre-cleaner. A scav­enger sys­tem also sucks out large de­bris, sig­nif­i­cantly im­prov­ing air fil­ter life.

The high ca­pac­ity cool­ing sys­tem and on-de­mand re­vers­ing fan keep the ma­chine run­ning cool. Spe­cial at­ten­tion was given to cool­ing the case drain oil from the HM825, en­sur­ing a cool-run­ning ma­chine. The over­sized, hy­drauli­cally driven fan spins at a slower speed over­all and only turns as fast as needed to main­tain proper hy­draulic and en­gine tem­per­a­tures.

In ad­di­tion to a re­fined cab for the com­fort of the op­er­a­tor, the Cat 586C Site Prep Trac­tor fea­tures “a lot of flex­i­bil­ity in var­i­ous func­tions,” said McDon­ald. For ex­am­ple, with the ad­justable creep con­trol, en­gaged with a con­trol on the joy­stick, the op­er­a­tor does not have to ‘feather’ the pedal and can leave his foot on the floor; the speed is eas­ily ad­justed with the but­tons on the joy­stick. Sim­i­larly, the at­tach­ment float con­trol al­lows the tool to fol­low the con­tours of the ground for uni­form, con­sis­tent mulching; it also re­duces op­er­a­tor fa­tigue be­cause it elim­i­nates the need for con­tin­ual ad­just­ments in rough con­di­tions.

The Cat 586C Site Prep Trac­tor also is known for its easy ser­vice­abil­ity. “One big thing is the fuel fill is at ground level as well as the elec­tric hy­draulic oil fill, which forces oil through a fil­ter be­fore en­ter­ing the sys­tem,” said McDon­ald. The Cat 586C Site Prep Trac­tor is the only ma­chine of its type in the in­dus­try with the fuel fill at ground level. Pan­els around the en­gine com­part­ments open for full, easy ac­cess for pre­ven­tive main­te­nance, and a tilt­ing cab pro­vides ad­di­tional ac­cess.

Cater­pil­lar cus­tomers are sup­ported by the in­dus­try’s largest net­work of deal­ers who will keep them up and run­ning with parts avail­abil­ity, field ser­vices, state-of-the art di­ag­nos­tic pro­grams, re­mote mon­i­tor­ing, and more.
