Rotarty Cutter question...

Hey y'all!
I've got a question about a Landpride Single Deck Rotary Cutter, Model RCR1548. The Problem with this is that it doesn't spin very fast; not fast enough to cut. It's powered by a New Holland 7308.
Is the shaft coming off the tractor supposed to spin at the same speed of the blades or does the transfer case of the Cutter increase the blade speed? I ask this because my friend is having trouble with this and upon inspection I noticed that the shaft speed is the same as the blade speed.
Any help on this would be greatly appreciated!
May God bless you all for helping out others in need!!

Hello Peter!

You may not get the best or most advice about this on this forum, since what you have is more tractor equipment...but...

The speed of the PTO from the tractor would have everything to do with the blade speed. Does the PTO driveshaft have a ratchet clutch that allows the attatchment to continue to spin after shutting the tractor off? If so, the ratchet clutch in it may be worn and cuasing low RPM.

If one revolution of the driveshaft causes one revolution of the blade, then the gearbox on the deck does not increase blade speed. It will be a 1 to 1 ratio. Is the tractor being run at full rpm? If he is driving in second gear with low engine speed, he needs to switch to higher rpms in first gear to bring PTO rpms up.
