 Finish mower rpm

Noticed on a finish mower that I bought used that there is a sticker/decal saying to use 540 rpm minimum. When I bought my tractor I was told that I would only use the 540 rpm setting unless I was using a tiller. After reading this sticker I got to wondering if I could use the next higher rpm setting on my pto to finish mow with. Am using a Shibaura compact grey.

540 rpm is probably the only speed you will use. Most attachments for small tractors are 540. 1000 rpm isn't used until you get to 100 hp & above. Most pto equipments says not to exceed the rated speed, which is 540 in the mowers case.

If the mower said on it a 540 rpm min then I would think you could use higher rpm setting. At 540 rpm the mower may not do the quality job you are looking for at the speeds you may want to cut. Find out what the blade tip speed is. A good mower will be running somewhere around 19000 ft/min. Your owners manual should give you these specs. With that in mind you can determine which pto setting to use.

I will say that last fall I bought a used 5' finish mower for my Yanmar 2500.I have found that the second PTO speed works better for my mower.At the lowest speed it does not seem to turn fast enough to do a decent job.On the second speed it runs much smoother and cuts better.Yes I know I should not really do this,nor do I recommend you do it,but that is what I do and it works.BTW it does have a 540 speed sticker on it and I think my yanmar runs about 670 in second speed.

I usually use the lower speed - recommended speed - because I'd rather make a partial pass than have some rotating part come loose. But PTO RPM is dependent on engine speed and sometimes when doing light work I don't enjoy hearing the engine roaring at full RPM just to keep the blades up to speed. Then I'll throttle back to half RPM and shift the PTO into the higher speed. Be aware that you lose torque at the PTO when you do this...so you need an engine that has enough reserve power to handle the load. If the RPMs stay constant when the load increases you are OK and have enough reserve HP.

Thanks for the replies. Went back and looked at the sticker. It says 540 min -1.
The -1 is a negative power that means per minute. Therefore the translation is 540 /minute. Have to wait for the snow to melt to check the tip speed of the blades.

The blade tip speed will have to be calculated. That is the quickest and simplest way to do it without complex equipment. This can be done by determining the gear ratio between the pto drive and blade drive. This will then give you the rpm of the blade and then from there multiply the rpm of the blade by the diameter of the blade times 3.14159. The diameter of the blade will have to be converted from inches to feet. This will give you the blade tip speed in ft/min. I would not exceed 540 rpm though. This is set by the manufacturer and engineering safety standards. Good Luck
