There is a "switch" arrangement to put it in and out of gear at this point. There was never a sliding Dog made for a 1-3/8" PTO shaft as by the time they came out the Rotovator had changed to one with a flexible PTO shaft like other implements. You will be very lucky to find one of these "dogs" now as most of the parts have gone long ago...John   [Reply]   [Send Email]

I guess am down to making one to get by. Skip   [Reply]   [Send Email]

Do you know the purpose of this shifter. Thanks in advance Joe Ferguson   [Reply]   [No Email]

If you remember the old tractors (TE20's & TO20's & 30's) didn't have live hydraulics so you had to keep the PTO running to lift anything and to leave the Rotovator running would be dangerous.....John PS someone must have had a new sliding "Dog" for the clutch made as they didn't make one for an 1-3/8" PTO, did you have it made or was it with the machine when you bought it. If you had it made the other guy could be interested as he has no sliding dog at all.   [Reply]   [Send Email]

I use it on the MF-50 or MF-135 which have live hydraulics..but never tried it with the TEA-20 because the ground speed is too fast. Second thing I just learned is about a sliding dog on the shaft...interesting...! never saw one. When I bough mine ~10 years ago there was a standard sliding shaft with universal joint at each end,1-3/8" on tractor end no sliding dog or other clutch device. The previous owner may had modified the driveline. I attached a pic I took few years ago...next time I go to the barn I will take a pic of the driveline and will post it if it can help someone. Thanks again John... I will be 61 soon and still learning a lot !   [Reply]   [No Email]

Can you take a picture of the lever you mentioned and send that too please and then I should be able to tell you more about it. Using the TE20 or TO20/30 on a Rotovator was, as you said too fast forward so you had to have a reduction gearbox fitted into the Tractor, Howard made one that went into the Hydraulic Housing and Sherman's made one that went into the Clutch Housing. Non-Live PTO doesn't present a problem with a Rotovator really other than you need to be able to stop the blades going around when the machine is lifted and that was on the original type that I thought you were describing. Yours should have had a clutch built into the pto that would slip under load.....John   [Reply]   [Send Email]
