Top-model tech­nol­ogy is now also avail­able for the Claas Ar­ion 400 trac­tor range

Farms & Farm Machinery - - News -

Claas Ar­ion 400 trac­tors in the com­pact 90 to 140hp range can now be up­graded with tech­nol­ogy that was pre­vi­ously only avail­able in Claas high-horse­power trac­tors.

These in­clude Hex­as­hift trans­mis­sion, CSM head­land man­age­ment soft­ware and a re­cently de­vel­oped dy­namic steer­ing sys­tem.

Such an up­grade may help farm­ers cul­ti­vate, for­age, and use the front loader with more pre­ci­sion, ac­cord­ing to Claas.

The new Hex­as­hift trans­mis­sion vari­ant now avail­able for Ar­ion 460 to 430 models can be used on the road at a lower en­gine rpm with four au­to­mated ranges and six power-shift stages, which re­sults in lower diesel con­sump­tion, the com­pany says.

The six power-shift stages al­low for a large gear over­lap so the most ap­pro­pri­ate rpm and driv­ing speed can be se­lected for each ap­pli­ca­tion.

All 24 gears can be changed us­ing the mul­ti­func­tional lever with­out hav­ing to use the clutch pedal.

The driver can al­low the trac­tor to change gear au­to­mat­i­cally by se­lect­ing the Hex­ac­tiv power-shift mode.

The CSM head­land man­age­ment sys­tem al­lows sev­eral trac­tor func­tions to be saved as op­er­at­ing se­quences with this sys­tem, such as elec­tronic con­trol units, power lift, en­gine rpm and PTO shaft. A to­tal of four head­land se­quences with up to 200 steps can be saved.

A newly-de­vel­oped Claas steer­ing sys­tem al­lows the driver to change the num­ber of steer­ing wheel ro­ta­tions for the same steer­ing lock an­gle at the touch of a but­ton and adapt it to the spe­cific task at hand.

This makes han­dling sig­nif­i­cantly eas­ier, Claas says, es­pe­cially with steer­ing-in­ten­sive work such as us­ing a front-loader or at a head­land. Us­ing this sys­tem, the driver can choose be­tween three dif­fer­ent modes for dy­namic steer­ing us­ing the colour dis­play.

About 90 per cent of all work can be ex­e­cuted with a steer­ing an­gle-de­pen­dent mode, where the steer­ing au­to­mat­i­cally ac­cel­er­ates the stronger the turn.

In the speed-de­pen­dent mode, the steer­ing trans­mis­sion is au­to­mat­i­cally re­duced as the trac­tor speed in­creases above 10km/h.

Us­ing the third mode, the steer­ing trans­mis­sion is man­u­ally ad­justed in­de­pen­dent of the speed or steer­ing an­gle lock.
