Snow Mid-PTO Troubleshooting / B2782 Snow Thrower Weak Stream

Does the engine bog down or change sound when this happens?

No, the engine maintains RPM just fine.

Do you have any rear PTO attachments? As far as I know there isn't a separate clutch for the mid PTO. Also if the clutch is slipping you should smell it.

I have a rear mount chipper. I've never smelled any clutch material burning while running the tractor.

I've been thinking... a few times a year (Winter), I'll have to blow the accumulated snow shed, that comes off the metal roof of the house, and out buildings. Most of the time, I have to break this hard packed snow up, and then run through it with the blower. I'm wondering if that was just too much for the mid-PTO to handle?

FIRST....check your clutch pedal free play at the top. Maybe all you need to do is adjust the linkage a bit.

If I power into too much snow my front mounted blower will stall the engine. I think it's been suggested to have someone watch the PTO shaft going to the blower and see if it's still spinning at speed or if it's slowing down. That way you can figure out if the tractor or the blower is the problem.

There is no clutch on the B3030 and no clutch pedal, but I"m assuming it is HST.

There is a clutch for the PTO and this could be slipping, but it is a wet clutch so hard press to smell it.

Are you running at wot?

Are you running at wot?

I typically run at the orange band (540 rear PTO) readout, on the Tach.

I got my WSM, in the mail, the other day. After reading through it a little, I wonder if there is a fluid restriction somewhere? Poppet valve at the PTO manifold?

This is a HST equipped tractor, so I wonder if it hydraulic pressure related? And not clutch disc related?

After reading through on how to remove the cab, I'm a little hesitant to do this on my own, without evacuating the R1234 from the AC unit first. If I have to do that, I may just bite the bullet and send it into the shop for the repair. I'm not equipped (specialty tool wise) to mess with that.

Anybody have an idea as to where I can source a hydraulic system pressure gauge set?

Surplus Center, Ebay Amazon or Tractor Supply for all have them.
The only question is what adapters you will need to connect them to your tractor.

I'd take a close look at the fan shear pin again and put a wrench on it or just pull hard on the fan to see if it spins. Quite sure I had something like this occur many years ago. The shear bolt was painted over therefore adhered to the shaft on both sides. It sheared but both sides looked fine. There was enough drag internally that the fan still spun up with no load but immediately would slow and stop under load.
