Re: What\'s ailing my bota 4610\"
SMM, Congratulations on getting yourself up out of there under your own power.

Your original report sounds great. You also say an on-site tech diagnosis seems to confirm your tractor's operating like it should. Since the fluid in your tractor's HST system is up to the proper operating level now, I think it would be difficult to duplicate the problem. I suppose you could always go back down that hill and try it again. /forums/images/graemlins/wink.gif
On my tractor there's a simple pressure test that can be performed to determine if the charge pump is operating correctly. Unless the tractor is not working right in some other way (ie; no movement, noise, wrong direction, etc.) the other major checkpoint outside of visual inspection of linkages, pedal movement, and oil level is the spin on transmission filter. On the Deere the HST filter is the main pickup point for feeding the charge pump. There are two anti-cavitation valves also, located in the valve block. Anyhow, oil from the sump is drawn thru the spin on filter by the charge pump. Kinda simple theory, No flow, No go. /forums/images/graemlins/mad.gif
On the Deere changing out the filter is SOP in eliminating diagnosed HST problems. Maybe your system's operation is similar. You might want to replace it yourself after this ordeal. A dealer will probably want to anyway.
Let us know how things turns out. /forums/images/graemlins/cool.gif
