B7500DT

[jerrym4]

The Kubota website lists the pto system of the 7500DT tractor as "a transmission driven PTO with overrunning clutch to provide easy gear changing".

What does this mean? Does the PTO stop turning when you press in the clutch? The overrunning clutch is for when you release the clutch?

Thanks,

My limited undestanding is that the PTO will stop running with the gear driven models when you change gears.

I originally was going to get the B7500DT, but one major use for me was a front mount snowblower.

I did not want the blower to stop running and maybe clog up with snow if I had to shift, and I also wanted the ability to let the tractor stop and let the blower continue to blow snow if I was in the heavy stuff.

The hydro will let you do all that. If you push the clutch in on the hydro, the PTO will stop running, but there's really not much need to use the clutch once the PTO is engaged and you're moving.

I originally ordered the DT because the hydro was about $1,900 more. A day after I placed the order, I called the dealer and changed it from the DT to a hydro. I felt it would be worth the extra cost in the long run. After two years of use and about 235 hours on it, I know I made a good choice.

I ordered the B7500HST about 17 months ago and have been very pleased with it. There is nothing better than the hydro for quick back up and forward operations such as using the FEL.

The only problem I have encountered so far is when I am using other hydos on the tractor. They seem to rob power from the tractor. I suspect some of this is due to my low engine speed. Normally do not over 1500 rpm as a rule.

Just curious if why you run such a low engine speed.
If you need more power crank that baby up-FULL POWER !!

Yup...they're a good little workhorse.

I run mine at 2500 rpm for the snowblower, MMM, and tiller.

That gives it enough power. If I don't, I have problems - either the snowblower will clog up, or the mower will leave a lousy cut.

I'll throttle back and forth alot when using the loader though.

The hst will rob power from one post if you have two implements going. I never really do. I do have a back blade on when I run the snowblower; I have to re-lift it every now and then because it slowly creeps down. When I do that, I can hear it take power from the blower.

That's interesting... My B7300 has a little mark on the RPM gauge just shy of 3000 RPM that indicates a rear PTO speed of 340 RPM, which is what is recommended for my brush hog. That is where I run my tractor when I'm using rear mounted implements most of the time (I lower the speed when running the backhoe when I don't want it to move too fast). But I would think that is the best speed to run at for maximum power without damaging the engine.

I think 2500rpm is the PTO speed of 540 on the B7500. I'm not at home now, so I can't double check it.

3000 rpm is the "top of the dial", so I don't think it's the RPM on the B7500.
