Lely mower

[welger]

had this lely mower con 3.2 from new for 4 years.this year we have put a case 165 on the front and I’ve mowed about 10 acres of 40 and the belts that drive the conditioner had broke with heat off the pulleys and gearbox. Iam in a nice crop of new seeds mowing speed 13 kph.how hot should the gearbox get? And do you think iam pushing it a bit too much?

The second gearbox does get hotter than the first one.Those belts must have been slack,I’ve blocked the conditioner on mine with real heavy crops,plenty of heat and smoking belts but still on originals.

I gave it a service in the spring checked everything parked it up and left it. Then went mowing this afternoon.luckily I had a spare set of belts the gearbox was a little short of oil .maybe the belts went slack since the service

What usually happens is you tighten the tension on the belts but the tensioner is siezed and doesnt move

Run all day been fine. Think it was a maybe belts hardly tight enough and slightly sort of gear oil. Thanks for all your comments

Are the conditioner tines worn? If they don't still have a square edge on they need turning out replacing.

Perhaps you shouldn't have serviced it. Nothing seems to work after that

Yeh right,lely conditioner tines round off after about 300 acres,by which time all the nuts will have seized with grass juice.There are about 150 of them...

The seal in the bottom of gearbox has a habit of going on those, the thing is the oil just drops into the bed and you don’t notice till it goes bang

I’ve mowed all day with this mower no problem. But how hot should the conditioner gearbox has been very hot , that hot that you can not touch it. Surly this isn’t right????

Post a pic of the conditioner tines. I reckon they will be worn out

Do it tomorrow. Do you think it tines then

If they don't have a square edge on the end then they will just sap power and take twice as much driving. And in turn heat the gearbox and belts

They do run quite warm

Sorry don’t agree,rounded tines won’t do much conditioning,but I don’t think they will heat the gearbox.The second gearbox on mine has always run hotter than the first one.Start to worry if it’s burning the paint off.Make sure the breather isn’t blocked,easily overlooked.

My mate had one. 8ft. 120hp was on its knees.
fitted new conditioner tines and it was a different machine

Depends how worn I suppose,maybe if they are totally rounded.But the sharp corner soon goes...

 

[pgilliat]

Totally agree with both points about conditioner tines, and the oil seal.
Have got the t shirt for both!
