Lely lotus combi 300 tedding settings, help needed

[farmer92]

Hi all
Got myself a Lely lotus 300 combi but I’m having trouble getting it to ted well, doesn’t seem to be doing a good job and is leaving it with an almost rowed up effect. Have altered top link, wheels under the rotor etc, book says to have higher speed and lower rpm but still getting the rowing up effect

Any tips?

How are the tines positioned? There is a wee bracket that folds down on the end of the tine arm, the tine is fitted round about it, one position for tedding, the other for rowing. A picture or 2 might help.

yep I’ve put the tines into the tedding position, as per the Lely book, outer position
yes I should have taken some photos, I will do later and upload to this thread , thanks

We have lely 770 tedder only, usually tines straighter, higher rpm (400-500 pto) top link shorter when grass wet/fresh cut.
As it dries lengthen top link and slow rpm, if you use higher rpm it can row up a bit.
Not familiar with combj but think it has closer or smaller rotors.

I suspect it may be the nature of the beast. Larger diameter rotors equals rowing up effect. Thats one of the reasons why people go to 6 rotor tedders, the rotor size drops from 1.5m to about 1.25m. Makes a massive difference to the spread pattern. The rowing up effect will also be greater in light crops and finer grass.

I have a 6m 4 rotor Lely Combi, which is in effect two Lotus 300s stuck together, and it can row the grass quite a bit when tedding. Whereas my Lely 6 rotor 7.7m tedder makes a far more even spread.

The drier it is the more it rows up but will still throw wet lumps out

The closer the crop gets to hay it will tend to row up rather than spread.
I never had trouble with the Combi tedding, but it would never row up as cleanly as a Haybob, made lovely fluffy rows but always left small fine bits unraked.

I thought the 600 and 770 share the same rotors? The combi has less hook on the tines so it lets go of the stuff for rowing up, different colour and part numbers.

Up to a point the book is right,go forward faster so the tines are"fuller" and working harder. They're happy in a heavy crop but will always row it a bit in light short stuff

As most of the above have mentioned, but will also reiterate.
Light or dry crops the combi’s will tend to row up unfortunately, but will still fluff it and throw over any green for drying effect , just looks a bit rough . Adjusting forward speed , and rotor speed has helped us previously but never perfect in above conditions.

The overall rotor diameter is definitely smaller on the 6 rotor machine. The 600 is 6m wide so 4 rotors cover roughly 1.5m each and the 770 is 7.7m wide so the 6 rotors cover about 1.2m each.

Edit: just been out and measured my two: Combi is 1.4m measured across the ends of the opposite arms, there's tine sticking out beyond that of course, and the 770 is 1.2m for the same measurement.

Fair enough. Someone told me 520/675 shared rotors and 600/770 so they were wrong. Tines are definitely different though

The 460 and 675 share rotors so I'd guess the 520 and 770 have the same size rotors.

That's where the cockup was then. Brochure said the 600 and 770 were made for heavy crops with heavier duty rotors.

Physics init , wet sh!t stays on the tines , dry stuff doesn't

 

[farmer92]

Thanks for the replies, much appreciated

gave it another go today and went better, went up a gear in tractor and seemed to spread out better, not 100% but better than yesterday, not the thickest crop ever but not particularly light, will be turning again tomorrow one last time before we bail so will see what it’s like now it’s a bit dryer too

My combi will tend to row up a bit more when it is thin and or dry too.

Heavy wet crops I go slowly (otherwise the slip clutch is always going off) and have the wheels up so that it throws it flatter.
