How'd the XPR2 concaves do against the OEM? Kevin shares his data

The XtremeAg team put the Estes XPR2 Concaves to the test this season. The results were pretty impressive across the board. Here is a look at the comparison results that Kevin took versus the standard OEM on his S680.



BARLEY
Rotor Speed: 820 rpm
Feed Accelerator: slow
Concave: 6

OEM XPR2
YIELD 86 86
SPEED 3.2 4.3
LOSS 3 kern 0
FM 0.70% 0.12%
SPLITS 0.05% 0
MOISTURE 13.2 13.2
TW 45.3 45.8
HEADER 35' Draper 35' Draper

Observations:
Grain sample on Barley was clean enough to put into seed bag settings are much more forgiven than OEM 

WHEAT
Rotor Speed: 800 rpm
Feed Accelerator: slow
Concave: 5

OEM XPR2
YIELD 74 74
SPEED 3.4 4.6
LOSS 2 kern 0
FM 0.30% 0.10%
SPLITS 0.03% 0.01%
MOISTURE 12.8 12.8
TW 61 61
HEADER 35' Draper 35' Draper


Observations:
Wheat was very similar to Barley in every test ran the ESTES outperformed the OEM 


SOYBEANS

MOISTURE 11.5 11.5
TW 57.2 57.4
HEADER 35' Draper 35' Draper

Observations: Exceptional grain quality much better seed bean sample and performance in tough conditions much better than OEM


Did not do a direct comparison to the OEM in corn.

CORN
Rotor Speed: 260 rpm
Feed Accelerator: slow
Concave: 26

XPR2
YIELD 167
SPEED 4.8
LOSS 0
FM 0.00%
SPLITS 0
MOISTURE 21.4

Feed Accelerator: slow
Concave: 28

XPR2
YIELD 205
SPEED 4.3
LOSS 0
FM 0.00%
SPLITS 0.00%
MOISTURE 19.1
TW 59.1
HEADER 16 row

Observations: Best grain quality least cracked kernels since going to STS machine. Performance is huge improvement, rotor speed extremely low, machine loss is rare when set up properly.
