Was it working ok? What took place? Will tractor roll, brakes are not locked?

Expert:  Curtis B. replied 6 months ago.

Tractor has a clutch, before the hydrostat, does it feel normal?

Expert:  Curtis B. replied 6 months ago.

There is an inspection plate on top of the clutch housing, remove it and see if the clutch output shaft is turning the input of the hydrostat.

the tractor was ok till i hooked up a three point hitch roto tiller. i have a three point hitch mower that worked fine, and when i hooked up my tiller it started slipping or acting sluggish. it seems that the longer the tractor runs the less it wants to move. i tried hooking up this tiller before and the same thing happened,so i thought the filters were bad and changed them and this worked untill i hooked up the tiller again. i then changed the oil and the filters and still not right.

So tractor will move when cold, but when you want to use more power, the transmission hydrostat gives out.

Expert:  Curtis B. replied 6 months ago.

Does it feel like clutch is slipping? Does the clutch have freepay in the pedal?

Expert:  Curtis B. replied 6 months ago.

If not the clutch, the hydrostatic charge pump may not being supplying enough oil to the hydrostat.

Customer: replied 6 months ago.
i just checked the clutch and it has about a inch and a half free play,the tractor does not move like it used to when it is cold or has set for awhile but i can move it. i jacked up the rear end and when i engage the tranny i am able to slow down and stop the wheels from turning,even in low range. the longer it runs even at idle the easier it is to stop the tire rotation.when the tractor was operating ok it would respond to forward and reverse quickly

is the pump mounted on the engine and is there a way to check it out
Expert:  Curtis B. replied 6 months ago.

So it appears to be the hydrostat loosing pressure as it warms. Worn charging pump or worn main pump and motor, which drive the unit. The charging pump is in the front end of the hydrostat!

Hydrostat, # ***** is the charge pump. See picture link below.

Customer: replied 6 months ago.
what is the pump for that mounts to the motor. are there any other screens or filters that should be checked. also i should have told you that the tractor sat for two years,i did start it and run it but that is all, and it was stored in my barn
Expert:  Curtis B. replied 6 months ago.

That is the hydraulic pump for three point and any other hydraulic function, but not for transmission!

Customer: replied 6 months ago.
are the charging pump and the main pump together,if so i guess i have my work cut out for me
Expert:  Curtis B. replied 6 months ago.

Charge pump can be replaced without disturbing the main pump/motor section. But at that point, you may want to go through the hydrostat!
