Honda 4514 problem

[Lazymt]

I have my late father in law’s 2000 Honda 4514H. I have used it regularly for the last two summers, working through basic mechanical issues. The engine was gone through In the spring of 2018 and runs like a top, very
reliable with lots of power. My issue is that lately a short, very steep hill I used to have no problem climbing has has the mower stopping just short of the top. The engine is running fine,it doesn’t bog down or anything but the power transfer is not there. No smoking or anything smelling hot. Any suggestions?

stop the mower on the hill take the brake off and give the mower a push
If it stops moving the instant you let go then the hydro is good .
If it rolls a little then stops it is OK
{f it races down the hilllike Mulga Bills bicycle then it is worn out.
Some times a change of oil and a thicker oil will extend the life of the tranny.

Also check all of the transmission pulleys and the clutch spring
Wear in any of them is like driving your car with your foot resting on the clutch pedal.
