Images: 3. Bush hog. Just got a new bush hog (4') for my jd650 can anyone tell the RPM they run to cut normal field grass most of what I've been told is to run max rpm on tach but low rpm setting seems smoother and seems it would be easier on the tractor. __________________.

hay balers, rotary tillers etc are all made to run at 540....so you should keep the rpms at that setting and pick a gear to adjust the ground speed, not use the throttle for ground speed. the only exception is the post hole digger..

most pto driven implements are met to run at the advirtised pto rpm... and a rotary cutter is one of those. you need to run the pto at 540 rpm for the blades to spin at the correct rpm to cut the grass and clean the blades and cutter so that it can cut more grass..

So I don't think that is too fast. My L4740 runs right around 2600 at 540 pto rpm. I always try to run my attachments at 540 rpm. There are exceptions of course.(ie: post hole auger). But attachments like mowers, bush hogs, tillers, I always try to tun at 540 rpm. They just seem to perform better at their rated speed. Last edited by L4740; 11-29-2009 at 11:32 AM.

It is usually marked on the inside of the speed marking ring. I would guess in the 1500 to 1800 rpm range.

Re: Bush hog. You need to run the tractor in the correct gear and the engine at 2350 RPM stated on the tractors tach to get the PTO RPM's needed to do the job efficiently at a safe travel speed.

I have a yn 2000 I currently hog in high 3 at 2000 rpm is this the right rpm and gear . It doea a good job just plain on grass to mow not to high. len. Run it in the low pto speed at full throttle. You're going to prematurely destroy the mower in the high range. It is only built for 540 rpms. I know about the pto 540. I was talking about the transmission high 3/7 at 2000 rpm's is this right are do I run full throtle.

I would run in 6th speed at 2400 rpm, pto 1. You're not really getting 540 pto rpm til then on a 2000. You should get an even better cut. Mike. You should run at full throttle and the engine RPM should not be over 2400. The PTO shifter should be in first gear (all the way down).

The correct PTO speed is on the Tach. use it the engine will work more better and use less fuel if it ts run in torq range. You are doing damage to the engine by not running at the correct RPM or lugging engine. This holds true in gas engines & Diesels will run hot if you do not run at correct RPM.
