Harvest plastic sieves.

Simple question, Case Ih flagship combine, sieves getting near end of life, harvest sieves are cheaper than OEM, just wondering what everyone’s thoughts and experiences are OEM versus Harvest sieves?

I put a set in our 8120 at beginning of last year.
Love them, less $$$, light, work with factory adjuster/actuator.
AND EASY to replace individual louvres if damaged.
We did a section of FLAT peas and had to really dig with the reel, that meant we did put a bunch of small softball and smaller stones through.
They knocked back a bunch of stationary chopper teeth/blades and a couple were broken completely and one took out 3 louvres and damaged a fourth.
It took about 40 min to replace them and next time I am sure we could do it with the seive in the combine and do it in 20 min or less now that we have done it.

We have a couple sets of Harvest sieves and so far good, easy to replace if broken. Definitely will replace my OEM sieves if they are damaged beyond repair with Harvest sieves.

We had a sieve come apart two years ago in a case combine.Replaced with a Harvest and really like it, will do other two combines when the time comes.Much lighter and cheaper.

Only sieve I ever had that allowed you to put pods in the tank and seed out the back, so for that they have everyone beat. Louvres are actually so easy to change they come off by themselves! And it was so much fun spending 2 days trying to get louvres out of the elevator and getting the steel pieces cut out of the cross auger and the bubble up auger. Oh, and unloading my semi with my air seeder screens to remove debris was such a great idea I’m surprised I never thought of that before! And the genius who put them in my combine even disconnected the cab adjust linkage and threw it away so you had to manually adjust them! Why didn’t I think of that! An extra 15 minutes to breathe in dust every time you want to try a different sieve setting. And he even custom made a nut with a little point on it to hold the sieve in position as the adjuster! Worked great in all crops, always had lots of empty whitecaps in wheat and lots of empty pods in canola.

PM me if any of you are interested in my used Harvest Sieve. Just needs a few louvres replaced.

Quick update, new top sieves OEM, $2150, per sieve, there are 2. I bought the exact same part number in the summer of 2022, $1375. Wow! Anybody know if there are counter tariffs on combine parts from the U.S.?

I have a hunch and would bet a bunch that the reason your seives are coming apart is because your shoe is in corn and bean position and not small grain position. The up down movement is for kicking cobs out the back. The motion is very violent in comparison to small grains. Ever notice how the combine shakes up down on the tires when the thrasher is on? Its noticeable even in the seat.

I have a stack of good factory seives against the wall in the shop. Changed over to Harvest Fixed Airfoil chaffers never had an inkling to switch back even once in any crop. Its the equivalent of increasing cleaning area 30%, creates a low pressure zone on the top of the arifoil just like an airplane wing. Keep your bottom seive at 14 and only ever adjust your fan speed. Losses cut in half, cleaner sample, and a higher capacity combine even a child could set.

One big problem with the factory style seives is uneven airflow, even out of the box they arent perfectly even, than add some kneeling or other damage. Wind will naturally seek the path of least resistance, you end up with areas with insufficient airflow and other areas blowing seeds out the back.

Wind does the cleaning, if you are keeping your seives too closed and wind too low, product will walk right out the back on the chaff matt, and the loss sensor won't tell ya.

Have a couple of the new series flagships with automation this year, I'll leave em stock for the time being until I can compare losses to my old girls with the airfloils. Ill let you know how the pan testing goes.

Essentially the shoe overloads in these machines. No comment on Harvests in flagships. But starting with the concaves was helpful for me.
