Shuttle shift usage Kubota M7060

[oosik]

Good Lord - hasn't anybody here ever driven a manual transmission car??? When you come to a stop you push in the clutch so that you don't kill the engine. Either do that or put the vehicle in neutral or both. Then step on the brakes.

Same on a tractor. The difference is - tractors generally have more lugging power and are geared lower in their lower gears than a car. The brake works just fine on a tractor. The brakes simply are not powerful enough to overcome the power of the tractor while still in a lower gear.

Yes, but it was his first time ever using the shuttle shift so it's just going to take some getting used to.

Hi there Farmer/neighbor! We got out tractor at Central Equipment in Truro. How about you? What kind of work do you use your tractor for?

Use it on a beef farm, so haying, loader work, tillage, snow removal.

I sent you a PM, so check your inbox.

Thank you Ovrszd and Farmer495 for the info. I, too, use the foot pedal to inch forward/back and when starting moving in high gear.

So far it's been "against my nature" to not have my foot on the clutch when shifting forward to reverse and vice versa, even in low gears/speed, but I understand it is ok to do so. I need to give my foot a break and just use the shuttle shift hand lever!

You can't operate it wrong. Unless you don't disengage either and try to stop by applying the brakes!!!!!

You said it! First day I got the tractor a year ago I used it real gingerly in low gears thinking I wanted to move slow and safe and not hit anything. On the only tractor I had previously used one had to have a foot on the accelerator or it stopped moving forward, so no real experience with the brake other than parking. On my new tractor it took one time only to learn that the gearing was such that the brakes are useless without the clutch. Fortunately I was in the center of a field when I learned about the power of the tractor in low gears vs the strength of the brakes!

I've driven manual transmission cars for years, but one can brake effectively at least a bit without the clutch on a car. Not so on this tractor, at least in the low gears!

Yes! One could accidentally tear down the garage that way!!! :cool2: hehe

If that happens you gotta promise to post pics!!!!

Hi y'all. I'm new here and learning to drive tractor for first time. My dad is old school (and a tad stubborn) so he is having a problem adjusting to our newly acquired M7060 kubota. He is used to the tractors from the 80's. My dad was using the shuttle shift and almost hit into the garage the other day because he said the breaks didn't work for him (he was a bit shaken by this). I'm thinking the tractor has to be in Neutral before depressing brakes on a shuttle shift? Or is something else not set right? From what I have read in the Operator's manual (which is very vague) it only says something about the torque in the axle being too high for braking. My dad had the tractor in 4WD at the time but I also noticed the same issue in 2WD. Before we ruin the transmission and whatever else can someone please explain how this works? Thanks so much for all answers/suggestions! Much appreciated.

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.

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

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.
