Miller spray’s lighter foot­print

Countryman - - MACHINERY AND TECHNOLOGY -

Lat­est Miller spray­ing tech­nolo­gies pro­duc­ing im­pres­sive ef­fi­cien­cies and bet­ter re­sults for grow­ers across the coun­try are now avail­able with a lighter foot­print to suit row-crop and medium-size farm­ing op­er­a­tions.

The new Miller Nitro 7310 self-pro­pelled sprayer, fea­tur­ing a 4500-litre stain­less-steel tank (or 3800L tank with 700L of di­rect chem­i­cal in­jec­tion ca­pac­ity es­pe­cially to suit row-crop farm­ers), is set to hit Aus­tralian shores early next year and re­place the Miller Nitro 5240 model.

Jon Bent, with Miller’s Aus­tralian dis­trib­u­tor, McIn­tosh Dis­tri­bu­tion, said a com­plete new, ad­justable chas­sis de­sign had re­sulted in a 5 per cent lighter ma­chine com­pared with the Nitro 5240, al­low­ing im­proved flota­tion and less com­paction.

Even weight dis­tri­bu­tion pro­vides bal­ance, with near-equal load on each tyre to max­imise power to the ground while min­imis­ing com­paction.

Mr Bent said this would be par­tic­u­larly ben­e­fi­cial for cot­ton, corn, sorghum and sugar cane grow­ers, as well as ir­ri­gated crop­ping pad­docks, where mul­ti­ple spray­ing ap­pli­ca­tions can cause com­paction con­cerns.

The new chas­sis has also pro­duced an in­dus­try-high 2m ground clear­ance which will bet­ter al­low late sea­son ap­pli­ca­tions in these crops, as well as win­ter crops such as canola.

Im­por­tantly, the Nitro 7310 uses the in­no­va­tive drive train sys­tem that has been one of the key at­trac­tions of the pop­u­lar new Miller 6000 se­ries sprayers, pro­vid­ing max­i­mum power and up to 30 per cent fuel sav­ings com­pared with equiv­a­lent-sized ma­chines.

The drive train was re­designed with a vari­able dis­place­ment hy­dro­static drive sys­tem and plan­e­tary torque hubs, pro­vid­ing faster re­sponses to speed changes through more ef­fi­cient trans­fer of power to the ground, even at lower en­gine RPM.

The plan­e­tary sys­tem is elec­tron­i­cally con­trolled and pro­vides a long list of new fea­tures like full-time trac­tion con­trol, cruise con­trol, anti-stall, in­te­grated speed lim­it­ing and four driver-pro­gram­mable speed set­tings.

The Miller Nitro 7310 is pow­ered by a 6.7L, 310-horse­power Tier 2 en­gine and of­fers a 56km/h road speed with four-wheel dy­namic brak­ing.

A vari­able speed, hy­draulic-driven cool­ing fan runs only as fast as it needs to, sav­ing horse­power and fuel while re­duc­ing noise.

Mr Bent said an­other ma­jor ben­e­fit with the lat­est model was the avail­abil­ity of a full range of boom op­tions, in­clud­ing a 48.5m Pom­mier RA Fal­con boom and Miller’s unique SprayAir boom.

Spray-Air booms have been used for a range of ap­pli­ca­tions in a va­ri­ety of crops, in­clud­ing ce­re­als, canola, pulses, corn, cot­ton and sorghum.

A new, ad­justable chas­sis de­sign on the new Miller Nitro 7310 sprayer has re­sulted in a 5 per cent lighter ma­chine com­pared with the Nitro 5240.
