Claas launches Jaguar Terra Trac forage har­vester

Claas has be­come the first man­u­fac­turer to re­lease a forage har­vester with fac­tory-in­te­grated crawler track.

First re­vealed at last year’s Agritech­nica expo, the new Claas Jaguar 960 Terra Trac has its man­u­fac­turer very ex­cited.

“Claas first re­leased Terra Trac for use in com­bi­na­tion with Lex­ion com­bine har­vesters in 1996,” Claas Har­vest Cen­tre prod­uct man­ager Luke Wheeler says. “This tech­nol­ogy has rev­o­lu­tionised grain har­vest­ing by sig­nif­i­cantly re­duc­ing soil com­paction, im­prov­ing driv­ing com­fort and im­prov­ing field ac­cess.

“It is no ex­ag­ger­a­tion to say Jaguar with Terra Trac is set to re­de­fine forage har­vest­ing per­for­mance,” Wheeler adds.

Avail­able in 635, 735 and 890mm track widths, the Terra Trac sys­tem, when com­bined with the tyre pres­sure ad­just­ment sys­tem on the rear axle, will al­low for im­proved field ac­cess and re­duce dam­age to crop­lands and head­lands, says the com­pany.

The 635mm-wide tracks of­fer a con­tact area of 1.3 square me­tres, which is twice as much as the 800mm-size tyres.

“The in­tel­li­gent head­land pro­tec­tion sys­tem takes the Terra Trac con­cept to an­other level,” Wheeler says. “Dur­ing turn­ing, the sup­port rollers in each track unit are pushed down hy­drauli­cally and the front drive roller is raised, ef­fec­tively re­duc­ing the con­tact area by about a third.

“This re­sults in the vis­i­ble avoid­ance of dam­age to the grass cover by the shear ef­fect when turn­ing,” he adds.

Tests con­ducted by the Kiel Uni­ver­sity of Ap­plied Sci­ences in Ger­many also re­vealed that soil pres­sure dur­ing head­land turns is less than that ex­erted by a wheeled ma­chine.

“Put sim­ply, this tech­nol­ogy means the har­vester won’t sink into the ground when oper­at­ing in dif­fi­cult, wet field con­di­tions,” Wheeler ex­plains. “This makes the go­ing so much eas­ier for the har­vester and the trans­port ve­hi­cles fol­low­ing it.”

Other fea­tures in­clude the Jaguar’s ex­tended chas­sis, which is ex­tended by al­most a me­tre in or­der to ac­com­mo­date the tracked as­sem­blies, which can os­cil­late 23 de­grees up­wards and down­wards. Claas says this piv­oted mount­ing sys­tem al­lows the Jaguar to be op­er­ated in dif­fi­cult con­di­tions.

With a nar­row trans­port width of 3.5m and a top speed of 40km/h, the Claas Jaguar 960 with Terra Trac is an im­pres­sive piece of ma­chin­ery, and will be avail­able in Aus­tralia and New Zealand from 2019.
