We just bought a 4430 that appears to have a weak clutch (if you apply the brakes in hi gear the tractor slows but the rpms do not change) What else should we check, replace while it is split? Thanks for any information.
 


It would help Tim or any other member to know trans type(QR or PS) of 4430.

If QR trans there's a clutch pressure test port on LH side of clutch housing & if PS trans test ports are on RH side. IIRC pressure should be around 155 psi for both types of trans.
 
I have a 4440 Quad Range in here now that if you stepped on the brakes in any gear it would slow to a stop like a car ...the trans pressure was 165..the clutches were peeled on the main clutch and the high low's..I'm thinking the wrong oil caused this one to fail. I am re-sealing all the operating pistons.
 
Sorry it is a QR, Just tried it some more in lower gears it will pull the engine down some but it will come to a stop. will get an adapter and check the pressure.
