    Converting 540 PTO to 1000

    I have a John Deere 5065e. The only PTO implement I use on it is a Bush Hog 2610L. Right now I am operating it with the 540 PTO. However, the Bush Hog is capable of handling both 540 PTO and 1000 PTO. Would there be any benefit to running it at 1000 PTO? I have a 1000 PTO shaft for my tractor as well as a 540.

    I am cutting just grass with this Bush Hog. Would running 1000 PTO cause it to "bog down" easier in thick grass or would it go through it easier than at 540?

    Thanks in advance!

    Bush Hog sells the cutter with an option to buy it set up for 1000 rpm PTO. The drive line will be different and only hook up to a 1000 rpm splined PTO shaft. The gear boxes will have different ratios, so the end result is same or near same blade speed. The main advantage of 1000 rpm PTO over 540 rpm PTO is the drive line is designed to handle more HP/torque.

    I would NOT change the coupler or get an adapter to let a 540 rpm cutter hook up to a 1000 rpm PTO. You would almost double the blade speed.

    When it comes to mowers I know guys that hook up to the 1,000 PTO and use 540 mowers so you can run the engine at 1/2 the rpm. If you have the power there is no reason to run PTO RPM from the motor. Just a thought.

    Not a good idea. My 2030 has a design operating range of 1500-2500rpm. PTO rpm is 2100rpm. Slow idle is 800rpm. Doing this will put the engine operation below design rpm.

    JD caution against excessive idling, which is what this would do.

    I would NOT run 540rpm cutter on 1000rpm PTO tractor.

    Some newer JD models offer ePTO which allows the 540rpm PTO to run at a lower (than standard PTO) engine rpm (about 1700rpm for ePTO), But still (the PTO) at 540rpm with a limiter to the throttle linkage to prevent over speed of the PTO when ePTO is engaged.

    I totally agree with Zebrafive. Operating a diesel engine under load below 1500 rpm's isn't good for the diesel engine
