I've got a (big)616 that doesn't have much power in 2nd gear and even less in 3rd.
How can I tell if the hydrostat is weak or if the 2 belts that drive the transmission
are slipping. I have made sure that the transmission is full and it has a new AC Delco
P13 filter. With the 1/4 inch breather tube at the top of the rear end I wouln't think
bleeding could be an issue. Any ideas?

These belts must be in good condition, or they will slip no matter how tight. If you pull the hydro cooler over to the right so you can see all the pulley adjusting system, take a look at the pulley grooves. If the bottom of the grooves are slick & shiny, then the belts are worn to the point you cannot keep them from slipping. If not shiny down in the groove, then likely a matter of improper tension. Sometimes the grease dries out in the lower shaft hinge point, not allowing full movement, thus not tightening the belt properly, even if the spring is in proper adjustment. I'm betting the belts are just worn out.

It would not surprise me if that part is dry or if the belts are worn.
It sat for a couple of years without running and I would be surprised
if they were ever changed. Do I have to replace them with Simplicity
belts or can I use belts from the farm store?
I want as much pulling power from this tractor as possible for next years
plow days.

I got a pair of PIX belts, 1/2 x 24". Belt number is A22K, or 4L240. Std unmatched belts do just fine for me and lots cheaper!

The belts were visibly loose and worn. Should I just move the motor forward to change the belts and check the ability of the tensioner? I don't see an easy way of getting them out of there.

I finally got in there and made some adjustments. The clutch had no free travel and the big tension spring was backed way off. I don't know how they used it like that. Now it has all kinds of power. Of course I'm going to use the old belts as well. Thanks again Olcowhand.
