ATLANTA, Ga. The straight-through crop flow
and unique kernel processor of the new Hesston Si
lapro™ 7500 forage harvesters are designed to deliver
great capacity, efficiency and feed quality with trac
tors from 90 to 300 hp.
All crop entering the pull-type Silapro 7500 har
vester is cut, processed and blown in a direct line. This
reduces power requirements and ensures a smooth,
uninterrupted flow of silage directly to the back of the
wagon.
“While the straight-flow design is common in many
high-capacity, self-propelled units,” reports Eric
Raby, Hesston general marketing manager, “its bene
fits have not been widely available in pull-type harves
ters. These include a big appetite, less plugging, and
the ability to easily fill the back of a wagon with the
most stubborn haylage—all with a small tractor.”
The optional kernel processor features a 6-inch
diameter top roll and a 10-inch bottom roll that both
rotate at 4,700 rpm. This creates a 60 percent differ
ence in surface speed that cracks more kernels and
uses less power than processors that use extreme pres

“By design, kernel processors that rely on pressure
create tremendous stress on bearings and other com
ponents,’’ points out Raby, “and are a common source
of plugging and crop-flow restriction. The 7500’s roll
ers, by contrast can be set further apart and are
mounted in-line between the cutting cylinder and
blower where they do not appreciably interfere with
crop flow or capacity.
The cutting cylinder is 22 inches (560 mm) in diam
eter and 24 inches (690 mm) wide with up to 12 full
width, tungsten-carbide-edged, helical knives
delivering cut lengths of Vi inch (6.3 mm) to 1 Vi inches
(38 mm). Standard features include one-bolt shear-bar
adjustment; slip-clutch overload protection; integral
manual knife sharpener; cab-controlled hydraulic
header lift and tongue swing; and cab-controlled elec
tric spout and chute.
Header choices include 7-foot (2.1-meter) pickup, 2-
row corn head for 28- to 36-inch (710- to 915-mm)
rows, and 3-row corn head for 30-inch (760-mm) rows.
Popular options include metal detector; rope or elec
tric wagon disconnect; tandem axles; 50-gallon (190-
liter) water tank; rear spotlight; vertical and horizontal
spout extensions; and 230-degree spout rotation.
