Shuttle shift usage Kubota M7060

[Tx Jim]

No dry clutch on Kubota Hydraulic shuttle. "multiple wet disk"

Your statement isn't 100% accurate. The hyd shuttle tractors have a dry damper clutch(see photo). Clutch pedal(inching) controls a hyd valve but doesn't have any direct connection to damper clutch which stays engaged all the time

Welcome KubotaGirl001, I am new to TBN also and enjoy reading all the experiences from other members. I have a M7060HD12 on order and will be posting some of my experiences in the future. My current tractor is a Mahindra 5035, about 50 hp, is what's called a Synchro shuttle shift is gear driven. I have to depress the clutch to change direction or grinding will occur. After driving the dealer's M7060, it will take some getting used to, for me to NOT depress the clutch to change shuttle F/R directions as the Kubota is a Power shuttle shift that requires no clutch to change directions. In my sixty three years I have worked my way up the tractor ladder from Ford 2000, Ford 3910, Mahindra 5035 and hopefully my last at M7060. To my knowledge all tractors except Hydrostatic transmissions require depressing the clutch before using the brake to stop the machine. Hydrostatic machines place F/R drive pedal on same side as the brake pedal, so as the F/R pedal is released the brake can be used to stop the machine. I'm not aware of a gear tractor model that automatically disengages the gear when the brake is depressed and all my tractors would never stop without depressing the clutch. I could get the Ford 2000, which is about 35 hp, to 'lug' the engine some and maybe even cut it off at low idle, but at higher rpm's they all required clutching. Good luck with the tractor as we will learn together when mine arrives.

Hi Wally, thank you for the welcome...and welcome to you as well! I'm looking forward to learning with you.

Yes, you'll learn together because the owner's manual for my M7040 hyd shuttle has maybe one sentence on how to operate the shuttle. Also, check your front axle oil after a few hours because almost all need oil added and it's sometimes a lot. Your will love that tractor and it's shuttle trans.

Thanks sixdogs for the tip about checking the front axle oil. I will do that. p.s. I love dogs too!!!

When you check the oil in the hubs or front axle, they all flow together. My M7040 manual isn't clear on that and you could overfill if you aren't careful. The right way for me was to fill the center axle, leave the plug off and add to the hubs. The excess will flow out the center hole. I let mine stand overnight with the plug out. They have UDT or UDT2 in them.

Should you overfill, there's a pressure relief vent in front of the radiator and will blow oil out of it and onto the battery platform. Don't ask how I know that.

Yes on the dogs.

Neat, didn't know that. I am guessing it's cause the "springs" in it like a regular clutch. Sounds like no way to wear it out if you can't engage/disengage it though.

I didn't either. I'm still trying to understand why the manufacturer would install a dry clutch that is never disengaged?? I'm not sure what the purpose would be. I guess I need to study the parts diagrams better. I totally missed that clutch when I searched the M7060 parts diagrams.

I know zero about shuttles but do know there are two styles, the dry and wet shuttle. That's not the dry clutch shuttle shift rather than the wet clutch shuttle shift, is it?

I am guessing the dry plate is solely to give a cushion for shock loads when shifting the shuttle. The friction material would not be "used" but the shock collar/springs around the center drive splines would still function. Cheap way to do it with existing parts and NOT use a dry clutch engagement.

The way I look at it, it's like a car with a cassette deck, it might be there but it isn't used, and it doesn't affect the operation of the transmission.

Yes, I have both types. Ford uses dry clutch and "mechanical" shuttle. Foot pedal required. Kubota doesn't use dry clutch and is "hydraulic" shuttle. No foot pedal required.

Edit: Actually I have three types. Ford 555A uses "hydraulic" shuttle with torque converter. It can be held in place with the brakes just like an auto trans car/truck.
