4230 PTO and Reverse Issues

Powershift Transmission. The PTO spins but bogs down easy. Only PTO implement I use is snowblower and it doesn't take much snow to cause blower to stop the PTO. Engine does not bog down.

Reverse gears take several attempts to engage. Once they engage it works fine and forward gears all engage fine. It seems that if I really push the gear shift far to the left that it will engage reverse better. Also sometimes takes some force to get into park.

I did search to try to find others with similar situation but didn't find anything. Looks like a 300psi hydraulic gauge is needed to test PTO clutch pressure. Any recommendations on a gauge? I found gauges online but not sure if there's a kit that would be better. Or would my local hydraulics shop be a good place to check for a test gauge?

Thank you for any help you can give.
 
When pto stops, travel also stops?

This would be a sure indicator that the dry clutch is slipping.
 
Hello Speedy welcome to YT! On the power shift I
would have someone in the cab move the shifter while
you watch under the cab in front of the right wheel.
Make sure there is no debris blocking the movement of
the levers by the cables. If your tractor is unusually
leak free in that area maybe a little lube on the joints
would be helpful. And use a pump oil can or what
ever you use needs to have a bit more viscosity or
thickness than some W pee 40. The actual cable that
actuates the reverse gears may need to be replaced.
On your PTO yes check the pressure. But if this
machine has a lot of hours on it like most of these old
extensively field tested machines I will say this. Let me
be the first to tell you to start savings your nickels
because a split of the old Deere is likely in your future.
That is what it takes to replace the PTO clutches in a
PS tranny.
 
Welcome to this forum
It may be too late to salvage pto clutch BUT has hyd filter been changed lately & suction screen checked/cleaned?

Any 300 psi gauge will surfice to check trans pump/pto clutch pressure with correct male ORB fitting.

I've never noticed it that way and looking back on how I use it I can't say for sure. If it's not a lot of snow the PTO will slow down but the tractor doesn't stop before I stop PTO and apply clutch.

If it's a large amount of snow the blower will stop, and tractor movement stops but I apply clutch and stop PTO as soon as I can. The tractor does stop, but since I apply clutch soon as I can I'm not sure if the wheels completely stop or if they would still spin. No MFA and no chains so traction isn't great.

I did change the filters, but think I'll also change oil and do another filter change.

How do I check the intake screen?

Thanks for the tips on checking reverse.

I'm expecting the worst, read that for powershift the cab has to come off and powertrain taken apart into 3 pieces.
