crop and drops it in a windrow from where it can be collected and tied
into bundles. As it does not have any reel so there are no shattering
losses. It is useful for harvesting small fields and can be used on
custom hire basis. |

TRACTOR MOUNTED VERTICAL CONVEYOR REAPER
Features:
The machine consists of a 76 mm pitch reciprocating cutter bar
assembly, seven crop row dividers, two vertical conveyor belts fitted
with lugs, pressures springs, pulleys and gearbox for the power
transmission system. The crop row dividers are fitted in front of the
cutter bar assembly and the star wheels are mounted over the crop row
dividers. The machine is mounted in front of the tractor and the power
to the machine is given from tractor PTO with the help of intermediate
shaft running beneath the chassis of the tractor and a coupling shaft.

with the help of pulleys and steel ropes. After the crop is cut by the
cutter bar, it is held in a vertical position and delivered to one
side of the machine by lugged belt conveyors and fall on the ground in
the form of a windrow perpendicular to the direction of movement of
machine.

8.4 SELF-PROPELLED COMBINE HARVESTER
Features:
Various designs of combine harvester having 2 to 6 m long cutter bar
are commercially available. The function of a combine harvester is to
cut, thresh, winnow and clean grain/seed. It consists of header unit,
threshing unit, separation unit, cleaning unit and grain collection
unit. The function of the header is to cut and gather the crop and
deliver it to the threshing cylinder. The reel pushes the straw back
on to the platform while the cutter bar cuts it. The crops are
threshed between cylinder and concave due to impact and rubbing
action. The threshed material is shaken and tossed back by the straw
rack so that the grain moves and falls through the openings in the
rack onto the cleaning shoe while the straw is discharged at the rear.
The cleaning mechanism consists of two sieves and a fan. The grain is
conveyed with a conveyor and collected in a grain tank.

SELF-PROPELLED REAPER BINDER
Features:
It consists of a frame, cutter bar, handles fitted with clutch and
brakes, seat for the driver, two drive wheels, one wheel belbow
the seat for steering, crop gathering unit and twine. The cutting unit
of this type of reapers may be disc type or cutter bar type. After
cutting, the crop is conveyed vertically to the binding mechanism
where it is tied by the twine and released to the ground in the form
of bundles. Self-propelled walking type models are available but these
are not popular due to high cost of twine. Reaper binders are suitable
for rice and wheat.

assembly, and straw compaction and tying units. It automatically picks
up the residue straw from the field with the help of reel which is
transferred into bale chamber with the help of feeder and then straw
is compressed with the reciprocating ram into a compact variable
length size. It also automatically ties the knots using metal wire or
nylon rope.

STRAW REAPER/STRAW COMBINE
Features:
Straw combine is pulled by tractor and operated by tractor PTO. It has
cutter bar reel, feeding auger and bruising cylinder like a
traditional thresher. Straw thrown and stubble left by the grain
combine is collected by straw combine and delivered to the cylinder
concave section, where it is cut into pieces and passed through the
concave. A reciprocating cutter bar is used for reaping the standing
stubbles and the portion of the straw left uncut by the combine
harvester. Straw, which passes through the concave, is aspirated by a
blower and fed into a trolley on rear side covered by a wire net. For
recovering the left grains from the straw, a sieve system is provided
below the concave.

SHRUB MASTER
Features:
It consists of cutting blades (swinging flails) fixed to the rotating
bar, gear box for transmission of power at right angle, universal
joints with telescopic shaft to connect the tractor PTO and gearbox,
adjustable side skids for controlling cutting height of shrubs or
grass, safety guard and hitching frame. It is an operated by tractor
PTO. The bar having cutting blades fixed at the ends is mounted on the
gearbox shaft. Thus, the vertical shaft of the gearbox provides rotary
motion to the bar. The cutting blades mounted on the bar swing open to
the cutting position due to centrifugal force as the bar rotates in
the horizontal plane. The cutting takes place purely through impact
and flails need not be sharp-edged. The blades are made of medium
carbon steel or alloy steel and hardened.
