Hesston by Massey Fer­gu­son in­tro­duced a new baler at the 2018 World Ag Expo that is the first of its kind. The new 2370 Ul­tra High Den­sity large square baler is the first and only Class 8 baler in the in­dus­try. De­signed to pro­duce dense bales from slick grass and crop residue, the ma­chine is suited for the pro­duc­tion of both feed and bio­fu­els.

The baler is es­pe­cially de­signed to meet the needs of large com­mer­cial hay grow­ers. “As their mar­ket de­mands in­crease, our cus­tomers have asked for even more ca­pac­ity, den­sity, and re­li­a­bil­ity from large square balers,” ex­plains Matt LeCroy, AGCO. “Our en­gi­neers in Hesston, Kansas, went to work, and the re­sult is the in­dus­try’s first Class 8 baler. It of­fers the through­put and re­li­a­bil­ity that large op­er­a­tions re­quire when har­vest win­dows are small and the tons har­vested per day is driv­ing an op­er­a­tion’s prof­itabil­ity.”


The 3×4-foot bales pro­duced by the baler are 20% more dense than those of Hesston’s older 2270XD model. Higher den­sity bales al­low hay farm­ers to be more ef­fi­cient. “More crop in the bale means fewer bales to bale, han­dle, move, store, and trans­port, which cuts op­er­at­ing costs and drives bot­tom-line re­turns for the op­er­a­tor,” LeCroy says in a com­pany state­ment.

Square balers of all sizes are cat­e­go­rized in Class 1 through 8 us­ing rated plunger load. Class 8 ma­chines are de­fined as hav­ing 750 kilo­new­tons (kN) or more of plunger force. The plunger load is the most mea­sur­able fac­tor im­pact­ing the den­sity of a bale.

The 2370 Ul­tra High Den­sity baler has a heav­ier plunger than other mod­els and op­er­ates at 50 strokes per minute. The max­i­mum load ca­pac­ity is 63% greater than pre­vi­ous mod­els with 760 kN of plunger force.

A heavy-duty main chas­sis frame is es­pe­cially de­signed to ac­com­mo­date the heav­ier, denser bales the ma­chine pro­duces. Over­all, the ma­chine has a straight­for­ward de­sign to re­duce main­te­nance and down­time. Fewer cylin­ders, hoses, cou­plers, and pieces of hard­ware mean fewer things that can wear or fail in the busiest part of the sea­son.

Ad­di­tion­ally, the driv­e­line in­cludes three clutches in the main drives, of­fer­ing more dam­age pro­tec­tion. Due to a new auto re­set clutch on the fly­wheel, get­ting back to work af­ter an over­load is eas­ier. This fea­ture elim­i­nates the down­time of re­plac­ing a shear bolt in a tra­di­tional fly­wheel clutch.


Op­tiFlow, the new pickup as­sem­bly sys­tem, al­lows you to op­er­ate at higher ground speeds while it feeds the crop into the baler.

With a tally of five tine bars and 80 dou­ble tines on the pickup as­sem­bly, the new baler has 25% more tine bars than older Hesston balers. Other fea­tures, in­clud­ing a large roller, curved wind guard, and pow­ered top auger, en­cour­age op­ti­mal crop flow.

The baler is equipped with two gear­boxes. A heavy-duty gear­box in­creases fly­wheel en­ergy. The other drives the plunger.

An ad­di­tional 28 inches in the bale cham­ber al­low greater den­sity con­trol. Dual-act­ing hy­draulic den­sity cylin­ders with a 7-inch di­am­e­ter help cre­ate con­sis­tent bales with the max­i­mum den­sity.

In or­der to re­duce down­time, the 2370 Ul­tra High Den­sity baler has plunger nee­dle slots with brushes that re­move de­bris be­fore en­ter­ing knot­ters. This im­proves knot con­sis­tency from the six dou­ble-tie knot­ters. The knot­ters can han­dle up to 800-knot­strength twine.

Two rows of twine boxes with a ca­pac­ity of 36 balls of twine al­low you to stop for re­fills less of­ten. The boxes swing out to give eas­ier ac­cess to com­po­nents be­hind.

Hy­draulic brakes and a scale-equipped roller chute are stan­dard fea­tures on the new baler. A life­time sealed packer crank and stuffer bear­ings, and re­place­able knot­ter drive cam lobe are also stan­dard.


The Bale Cre­ate user in­ter­face is a key fea­ture of the new baler, mak­ing per­for­mance in­for­ma­tion avail­able, al­low­ing bet­ter de­ci­sion mak­ing in the field. You can see bale for­ma­tion data like flake size, flake count, and bale length in real time from the trac­tor cab. Bale weight and other in­for­ma­tion are avail­able through con­fig­urable boxes on the screen.

The baler is now avail­able through Massey Fer­gu­son and Challenger deal­ers.
