mott flail mower

[Kevin]

Hi everyone
I recently acquired a 48" mott mower and wanted to know if anyone uses a 5" pulley on the pto? If so is there much advantage? I tried the mower and seems to cut the grass very well with the 6 1/2" pulley.
thanks

Kevin I think this is the right one. A friend with a 1958 cub with a dealer installed Mott Flail has this pulley.

Kevin, I tried a 5 3/4 inch on mine and it does give a little smootehr cut, but the difference is minimal. it does take more power to run it that way, and if you do any rough service cutting, or tall thick grass you will notice the power reduction. The shat is already turning nearly 2,00 rpm, and th 5 inch pulley will raise it to almost 3,000. That shaft is heavy and if you don't have it perfectly balanced (which very few are) the bearings will fail a lot faster.

Thanks for the help. I just wanted to know if it helped much. It seems to cut good spinning to the front to cut my yard and when I cut something heavier I turn it to cut toward the back. All things considered I was impressed with the cut I received from a Flail mower. I am considering replacing all the blades and pins. Mine look original. I purchased the mower for $125 with everything to mount and a special grinder to sharpen the blades. Seems like a pretty neat mower setup.
thanks again

You got a great buy. The pto pulley is worth that much. How about posting a picture of the grinder. I use a 4 1/2 inch angle grinder to sharpen mine. One note, the blades are surface hardened, and after one or 2 sharpenings they really dull fast.

Kevin: One word of caution on twisting the belt so it throws cut grass to the front. I ran mine that way when I first got it but soon found out that the grass was plugging spaces between the vanes of the radiator. You may need to check and blow accumulated clippings from the radiator frequently. Dan

Yep, tried that too with the same results. there was an optional mulching shield that could be put on the front wen throwing grass forward.

I forgot to paste the link I had in mind.

Iknow it says Rotary mower and am now in a sweat if it is the right one.

Yup, that will work. I have used them. The one thing I didn't like about it was that in order to get it for enough to the rear to line up with the idler pulleys I had to mount it with the bolts facing the transmission. Made it a real pain to install and remove.

Mine seems to have a piece of rubber making a shield seems to work very well keeping the grass clippings from flying forward I would like to make something for it out of metal maybe in the future. I will email you the pics I can't seem to get them to post. I'll have to practice a few.
thanks
