[AT] Ih 504

[Kevin]

Question  Ih 504 tractor gas burner, got it to move round hay in cold weather.
Am having problems lifting some, is this tractor hyd system not the same as 340- 560 ? They use the same pump, this 504 has always been light in the front and seemingly weaker on hydraulic lift power than either a 340 or 560.
Some of these rolls weigh #2000 +
Any ideas on how to get more lifting power out of this tractor ?
