Kubota MR6000 mower deck pulley ????

Crazy Horse · Mar 5, 2018

For a Kubota MR6000 mower deck, I am looking for a the center v-belt pulley. There are three of them on the top of the deck, all three have the same part number I think. The two outside ones attach to and drive the outside blades. The middle one attaches to and drives the middle blade and this pulley is mounted to the vertical shaft from the central gear box. In the link below, the parts diagram lists what we need as #24. It is no longer available from Kubota. The actual Kubota part number is 7072199780.

Anyone have any suggestions as to where a person might be able to find this pulley? I suspect the MR6000 is getting pretty old by now. As a last resort, I suspect a person could fabricate one.

Thanks for you help with this ..... Crazy Horse

All I can find is 70712-99780 pulley which replaces a whole bunch of pulley #s.

Kubota Parts Site shows it as 70721-33550. Messicks says it cost $84.62.

Thanks Charlie ...... yes, those numbers can jump around a bit. I think we are going to fabricate a new
pulley, this whole mower deck might be borderline not worth putting a bunch of money into. Someone
fabricated it to a class I 3-point hitch rear setup for a small tractor at one time in it's life so it is no
longer a belly mount on a Kubota tractor. The gearbox also needs new bearings and seals.

Do you know whether or not that center pulley is the same as the two outside ones? We don't have the center
pulley anymore, long story. We could use that as a pattern if it matched for bore, keyway, diameter, etc
for making up a new center pulley.

Crazy Horse: I don't know anything other than what the parts book says. Sorry.
