Farmall 450 Diesel Hydraulic Problem? Just Bought

I Just Bought A Running Farmall 450 Diesel For $1000 Which Was A Great Deal But Guess They Guy That I Got It From Says The Hydraulics Are Goofy Like Wont Raise A Haybine All The Way And The Power Steering Works Then Dont He Has Changed The Pump Already And Gave Up Any Ideas?
 
well first off they only made 1250 lbs pressurre when they were new , and depending on what size cylinder is on a haybine it may not raise it . For a 450 to lift lets say a 469 you had best have a 3x8 on it . Most newer stuff uses smaller dia. cylinders because most of todays tractors ar up in the 2000 psi range or higher . Now as to your steering problem there are a couple things that would need be checked .
 
If the steering wheel turns hard like no powersteering hit one of the hydraulic levers and put turning pressure on the steering wheel the same time. If it turns them, you have the valve that directs oil to the powersteering pump sticking. Mines that way and I can live with it.
