Hey Guys, Another update this time with a pic. Thanks to all who have helped me try to troubleshoot this issue with my 1450 that I have included in the previous posts below. I have eliminated the engine tonight. I manually overrode the governor tonight and it did not fix the problem with the engine bogging down when the transmission is under a load. Furthermore the picture I am including has a picture of what I found on the top of the hydro. The right check valve (from the drivers seat) is seeping oil out the hole in the top surface of the valve. This was only after running it for 5 min or less in 50 deg weather. I am convinced of my theory that the transmission is what is malfunctioning causing the engine to stall. What does the oil seeping out the valve mean. Please see the picture. Does anyone concure with my diagnosis of this? Is it time to replace the hydro pump? Thanks again,
Chad

Chad, My 782 does the same kind of bogging every now and again. Usually when I attempt to take off quickly. It doesn't do it all the time, and its random at best. The sudden load confuses the engine for a moment.
The cause is the govenor along with carb settings on a well worn engine. I obtained this tractor becuase the PO couldn't get the governor set right and after literally crashing it into the nieghbors Suburban, it was passed on. (after 20 minutes in my garage, it was purring like a kitten. sorry PO, but thanks for the nice tractor.)
It's the govenor pulling it down... and reguardless of the carb being at "factory settings" maybe they should be adjusted to compensate for the years of use. I bet if you bypassed the govenor for a while it would never do it. (becareful not to over rev it of course.)

Could the check valves have anything to do with this problem? Just a reminder that this tractor did sit for 10 years before I got it running again.
Thanks

It also has a brand new coil and condenser on it. I have practically eliminated the engine as the culprit.

Yeah, Carb has been rebuilt and is set to factory adjustments. Then engine does not give me any indications of any issues. It pulls just like it should when the transmission is not bogging down. I have no reason to suspect the engine. Governor and everything are functioning properly as far as I can tell.

Chad M.
One sure way to find out if it's engine or hydro is to remove the drive shaft and fire it up.
My 1450 did that once and I also had a 149 do it.
Both times I changed the coil and it fixed it. I got LUCKY!

Are you sure the timing, carb, and governor are all set correctly on the engine?

Follow-up: A month or so ago I posted regarding my hydro transmission on my 1450 causing my engine to bog down and nearly stall. The two suggestions were 1) Change the fluid and filter to Hytran Ultra. Which I did but it did not fix the problem. 2) Do a trunion repair. Regarding the trunion, It is notched and needs to be repaired. I know this will fix the speed variation but I do not think it will fix what is causing the transmission to seemingly bind and bog down the motor. Does anyone have any suggestions? Is the hydro overheating? It does seem to take time for it to get warm before the problem starts to occur. Thanks!
