424 Fluid check

Our ATV Club has a 424. Bought a service manual but checking or how to must be in the user section. PTO lever near (L) foot leaking fluid while bush hogging trails and losing Lift after on a sharp angle. Pulled the top plug on rear behind seat but looks full. Is there a different place to check. Thank You Michael
 
PTO lever shaftmust need a new oil seal. That leak is TRANSMISSION oil. The 3-point unit under the seat serves as the hydraulic reservoir, SEPARATE of the tranny and rear end.

I can't recall, offhand/ what the level of the hydraulic oil should be when you remove the plug to the right rear of the seat... you would THINK there would be a dipstick, but there ISN'T.
 
I think six inches down from the lip of the standpipe on the lift box. that would put it about 2 inches down into the liftbox.

And yes unless you have the sux hydraulic pump on the front of the engine crankshaft the lift box and tranny are seperate.
 
NO standpipe on a 424. At least mine doesn't have one, and the partsbook just shows a plug, NO standpipe.

(#8 in the illustration.)

hmm well the piston and such in the 424 is the same as the 444. I put a 424 lift piston ans cylinder in my friends 444.
I think the liftbox case is the same as well.
Fill plug on top right rear of the liftbox ?

Anyway in the 444 it works out to come up nearly to the bottom of the fill tube in the lift box, which protrudes down into the liftbox a bit in the 444.
it gives about 2 inches of airspace above the oil level to the top inside of the liftbox case.
