Round hole sieves

Have a set for rape on the 1085. Didn’t seem to work any better than the finger sieve. In fact the finger sieve (closed right up) seemed better at aligning and sliding the pods off, whereas the round hole sieve got bits of pod stuck in the holes. The air flow and separation also seems better through finger sieves. It’s the draft that separates the chaff from the seed more than the shape of the sieve hole IMO.
Personally I wouldn’t bother but other combined might be different so can’t say generally.

Any one use them now for small seed crop. Borage. Linseed or canary seed
what size

we used to have a rape sieve in the 70s

I wouldn’t bother. Combine airflow is carefully designed to match the sieves, sticking something in that it wasn’t designed for could seriously affect performance. I learnt that lesson many, many years ago when I used to be a combine demonstrator. I had one of the first Dronningborg combines in MF colours in the country and MF in their infinite wisdom decided to fit frogmouth sieves as fitted to their previous machines. It gave serious problems so I changed the sieves one’s it was designed with and it cured it completely. Unless you’re using a ‘70’s combine I’d leave it alone.

Gracious takes me back to the 985s and 1085s used when I was working as farm trainee manager in mid / late 80s. I can recall having to take out those screens daily to empty the holes of rape stalk / pod debris or the screen would become flat!

Round hole sieves are only any good in dry conditions IMO.
We used to use a Petersen sieve on top with a 4mm round hole below for rape.Worked well with good sample and low losses as long as it wasnt wet or green conditions.

Yes, swapped the standard adjustable ones in our nh for fixed round holes one from a class , cleaned the sample up an a lot and easily, what comes out the grain tank now (as long as you dont drive too fast ) can be drilled without further cleaning ...but actually it is a (late) seventies combine.

Used a round hole bottom sieve in a MF 34 in rape back in the day......... probably the only good thing about that combine aka Dronningburg !!

The Dronningborg was an excellent combine until MF got their hands on it and ruined it, mine was one of the very first MF ones, it was painted Red and Chocolate but very soon started turning Green and Orange in work. I started in Hampshire in the second week in July and drove it from demo to demo through Surrey, over to North Kent then south through Kent and both Sussex’s. I did that loop twice before finally finishing in Surrey at the end of September. Only had two breakdowns in that time, a drum belt snapped combining oats at 28% in the rain ( that’s what the farmer wanted to do ) and a track rod end snapped at 1am.

My neighbour had an early red one too . Think it was a 27 model cant remember exactly , but anyway his man was also cutting oats late at night and the boss had told him to finish the field at all costs as there was a bad forecast.
He accomplished his mission, dropped the header and turned out the gap onto a quiet country road when the back axle gave up and the two back wheels went in different directions . The time coincidentally was 1am.
Being night owls there was lights on in our house so he knocked on the door looking for help. I parked behind it with hazard warnings on while he went off to rob some cones from the nearest roadworks.
And there it sat for the next 3 days in the rain untill an orange axle had been sourced.

The following year a John Deere appeared.

My 29 xp had major sieve box issues and we ended up getting a new much stronger box made which sorted that end out . We got a replacement bottom sieve from combine fabrications which was a round hole instead of the adjustable frog mouth origanal . Ever since the airflow has not been great and in wheat flour at high moisture a lot of chaff can end up in the tank . Fine in any other cereal. Would a frogmouth sieve be the answer or a sieve out of an Orange dronningborg ?? The breakers have a dronningborg atm and maybe the sieves are intact .
Thanks in advance .

Fortunately, Massey seem to have learnt quite a bit from the Dronningborg fiasco - this was from their statement to the SEC upon acquiring 100% of Laverda in 2010.

A similar experience re a JD apperaing after the fiasco with 2 MF combines. First was a 525 bought new and returned after the first season, second was the 34 which was equally dissapointing but it did at least have air con ! Was replaced by this ...... chalk and cheese 20 odd years ago !

We were contracting in Suffolk with one of the last 865’s , moving the combine One Sunday morning, down a single track road we came upon a new combine ahead of us stuck in the road. Thankfully that day we were towing the header seperately as the machine was the local MF dealers demo machine with a broken rear axle, not sure of the model But they obviously had serious issues with those Dronny machines. Their were a few choice words said all round as we had to back a fair way to find another route which took us through the middle of Eye. Remeber those 865‘s were 14’6” inches wide without the header!
