Running 1000 rpm lely mower at 540

[Boo-Boo]

Don't to think you can turn the gearbox. Will this make it 540?

Sorry , I mean try to buy a 540 gearbox from a dealer . Or talk to a lely or ex lely dealers, they should advise or may have a 540 box available . They're a lovely mower and kind on a tractor linkage and good cut

No but I did have a look. I'll look again to double check

Not too hard to confirm ratio by turning one side and watching other.

Yes I can confirm it's a 1:1 gearbox so turning it won't make a difference. When u put the tractor in 540 e and rev her flat out u get 800 at the shaft but when u attach the mower it knows what ur trying to do and shuts herself down to 600. Which does cut but I can only go 2mph. Any faster forward Speen doesn't cut clean. So the next question is can I stop the tractor shutting itself down is ther a fuse of something I can remove ?

Get to the field, run the pto (engine) flat out and try it first. As you have no conditioner, the torque load should not be an issue as cutting grass is low power consumption, as long as you travel slowly.

I know someone who in their wisdom ran a 1000 speed lower in 540 speed and all the knife carriers wore out very fast.

Basically as they weren’t spinning fast enough the centrifugal force wasn’t enough to keep the blades out

Yeh i have tried and as I say the tractor shuts itself down annoyingly..... it does work if I don't go over 2mph forward speed

"Tractor shuts itself down" what do you mean, Stalls ?

How many HP is the tractor ?

 

[Mur Huwcun]

When you move the lever to 540E it pushes against some form of switch to tell tractor it’s in E range. That’s only thing you could change or trick

Tractor limits the revs when in Economy to stop over reving of pto implement

Mine is a reduction gearbox , 1000 in 750 out , needs to be full chat to cut properly

The don't use 540e (which is normally around 700/750) use standard 540. Max engine rev's, should be around 650 pto.

Yeh it revs to about 620 bu it's hardly fast enough

I'll have to see if I can see a switch

Different mower to the op.

MF must be going backwards. 4 speed PTO was on all the Massey's I had since 1988. And up to 2000.
1000e great for mowing. 10' moco.
Don't understand why all tractor's haven't got 4 speed .

 

[pgilliat]

Have you checked you can't get a 1000 speed shaft for the tractor?
Does seem a massive step back if you can't

 

[Highway star]

It might be possible to change the gears in the tractor to provide 1000rpm in place of 540E ? I think they're fairly accessible on those, just bolted on the tractor back end
