Ko­matsu re­leases the agile 901XC forestry har­vester

Earthmovers & Excavators - - News -

Ko­matsu’s new 901XC is an agile forestry har­vester de­signed for thin­ning in hilly ter­rain and on soft ground

Part of Ko­matsu For­est’s new XC se­ries, the 901XC has eight wheels for im­proved sta­bil­ity and ma­noeu­vra­bil­ity, and low ground pres­sure – which in turn means less ground dam­age.

The de­sign is based on the decades-old ‘Ko­matsu con­cept’ of a cen­trally mounted cab and crane, which pro­vide a good bal­ance be­tween ground pres­sure and cen­tre of grav­ity.

Other key fea­tures are a rigid ar­tic­u­lated joint and a swing axle which, in com­bi­na­tion with the cab’s tilt cylin­ders, of­fer bet­ter sta­bil­ity and han­dling in dif­fi­cult ter­rain.

“More­over, the har­vesters in the XC se­ries are equipped with the swing­ing rear axle seen in our six-wheeled har­vesters, teamed with a bo­gie to cre­ate a highly unique so­lu­tion with twin sus­pen­sion sys­tems, the Ko­matsu Dou­ble Sus­pen­sion Com­fort Bo­gie, and ex­cel­lent off-road han­dling,” the com­pany says.

Out­side the Europen and North Amer­i­can mar­kets the Ko­matsu 901XC is pow­ered by a 6.6-litre, 6-cylin­der 66 WF-4V -AWF diesel en­gine de­liv­er­ing 170kW at 1900rpm and meet­ing EU Stage II emis­sions stan­dards.

The power-op­ti­mised hy­dro­static transmission en­ables the en­gine power to be fully utilised, pro­vid­ing bet­ter per­for­mance in dif­fi­cult ter­rain and ex­cel­lent climb­ing abil­ity, the team at Ko­matsu For­est says.

The ma­chine is also equipped with Ko­matsu For­est’s 3PS three-pump hy­draulic sys­tem which de­liv­ers a flow of 548L/min at 1500rpm. This sys­tem al­lows crane and head func­tions to be used si­mul­ta­ne­ously while re­tain­ing max­i­mum hy­draulic power.
