    There is a second pto shaft on my tractor underneath the pto shaft that I always use. What is it for? Lower implements?

    Probably 1 is 540 and other is 1000. You should be able to tell easy that 1 spins twice as fast as other. Or else 1 is ground drive in which case it will only turn as you move and its speed will be relative to your travel speed. But far more likely its 540/1000. What make of tractor and has 1 shaft got 21 splines and other normal.

    You need to be awful careful using 1000 PTO speed on gear that it wasn't designed for. Most the gearbox's weren't designed for that speed and running them over the recommended amount isn't going to extend their life. You don't actually know what speeds your spinning the PTO at. It's not something you can just judge by eye, it's too fast for that. Your also putting the engine under far more strain. Your well away from the tip of the power curve, so your just working it the whole time.

    If you want to save diesel, increase your ground speed, check tire pressure, make sure everything's clean and clear (oil, filters etc) because a bad gearbox in a baler costs a tidy sum to replace.

    Yea fair enough, I'd say you'd probably hear if the engine was under a large amount of strain. It might be safe enough cos the shearbolt would break if I put too much torque on the topper. I might just leave well enough alone, as it could end badly; I'll probably mention it to the owner though.

    Took the topper out for her first spin on the paddocks today. 1000 box and 1100 revs. Tractor just ticking over and nice handy gear, no mad revving and going light on the diesel. No problems and a lovely tidy job

    Both shafts have the same splines as far as I remember. I will take the cover off today and see what the difference is with the pto turned on. Someone suggested a long time ago that it spun the opposite direction but I doubt this is right. Its a Lamborghini 879-90 btw.

    Is it a high Horsepowered tractor? With a lower horsepower tractor and the engine revs higher, you'd actually use less fuel per acre.

    So lads whats the consensus. Tractor is MF 4345. It has selectable 1000 PTO & 540. If on the power washer, wagtail & light topping with disc mower select 1000 PTO and run at say 1100 revs on clock or where dial is marked. Tractor has digital dash which reads PTO speed seperately so as long as I dont exceed 540 rpm on dash it should be fine. I presume there's no need to change PTO shafts if doing this? This would allow me to tip away at lighter engine loads rather than reving to 2200 revs and having the tractor roaring on light work.
