I just purchased a 1974 434 international , and it did not come with a manual. I would like to know how to check the level of hydraulic fluid ? also it doesn't seem to have power to lift much . I have a small bucket on the back, put it seems to have difficulties in lifting what I put in it. Any advise on these things would be great. Also can you tell me if they had any problems with these tractors, I'm planing on hauling wood with this tractor , 16 foot logs can this tractor do it. ? I don't find the traction all that great, compared to my 135 Massey tractor, Maybe I have to get use to it first. thanks Dean

Dean,
Contrary to what the other posts suggest, there is no connection between the hydraulic oil system and the transmission oil system on a 434. The 434 hydraulics is a self contained unit under the seat with a fill plug at the right rear upper corner of the housing. The hydaulics should be filled with HY Tran oil so that there is about a 1/2" air space between the top of the oil and the housing.The transmssion oil is checked with a level plug on the side of the transmission just ahead of the left footboard. Oil is added through the big plug beside the gear shift. It is fairly common for 434's to be contaminated with water in the transmssion so look at the oil and if is milky, you probably should change it. The transmission uses #90 EP (extreme pressure) gear oil. Don

If it is like my 2444/444 then there is a plug on the side of right hand side of tranny. Fill till fluid comes out that plug.

Does yours only have the one engine mounted hydraulic pump ? If it also has a front mounted pump driven from the front crank pulley then the level is 6 inches down from the top of the filler plug beside the shifter. Which is about 5 gal more than without the auxilliary pump.

There is also a suction screen on the end of the suction line where it goes into the lift box on the rear of the tractor. This could be plugged causing poor hydraulic performance. Or water in the fluid ?

Also if you drain your fluid to change it there are 2-3 drain plugs in various places you have to open to fully drain the hydraulic fluid. You have to open at least 2 plugs underneath the tranny/rearend and one on the bottom rear of the lift box mechanism. Also when refilling fill the liftbox first. It will hold a couple of gallons and the excess will overflow into the rear end sump. Filling this first will make things go smoother. complete the filling at the tranny filler/vent plug beside the shifter on top of the tranny. Fill to level described in my previous post. As I recall your tractor holds about 12 gal or so of fluid, unless you have the auxilliary front pump then it is about 17 or so gallons.
