Well yes you can replace the 12 GPM pump with a 17 GPM pump BUT the problem is that the filter on a stock 560 is only made to handle 14 GPM when clean and this will give ya fits . That is why i was saying that a PTO driven pump would be a better chose that way you could go with lts say a 25 GPM pump or larger and us a filter inline that could handle atleast 30-35 GPM flow then make up a holding tank that held 25 to 30 gallon along with a oil cooler as that oil will get hot . This is something else to think about as a 460-560 tractor does not have a hyd.oil cooler And running a 17 gallon pump and only 16 gal. of hyd. oil the oil will heat and no way to cool it and two hyd. motors will heat the oil fast . Now this is just my thoughts here . Back when 560's were built there was not much use of hyd .motors and there was not the need for a lot of hdy. flow . Now today with more use of hyd.'s the newer tractors have larger hdy. capacity and flow along with higher pressures .The 560 area tractors did well with the 1200-1500 lb. range lifting implements and got along fine. Now here we are today and every once in a while some one will come on here and ask why there older tractor will not lift some pice of equipment and this is because first off that 1200-1500 lbs if the system is up to it's standards is 500 to a 1000 lbs . of pressure light or it will raise it slowly because the system does not have the flow . Over the years of working on tractors i have many times replaced the relief valves on 06's and thru the 66 series from the 1750 relief to the 2350 relief so that that tractor could raise something . I know that when my buddy and i wrap silage bales that his brother's Oil ALL OVERSwill wrap about 15 to 20 bales ok but with there limited oil capacity the oil starts to heat and things slow down because of the heat .But when we put the wrapper on my 806 because of the fact that the 806 has about more oil in reserve plus a bigger oil cooler we can wrap bales from sun up till way past sun down and never get the oil any hotter then around 160-170 degrees well with in the working range .Plus it will wrap bales twice as fast as the OIL ALL OVER . Your barn yard engineering is great but just needs a little tweaking.

Today's Featured Article - Choosin, Mounting and Using a Bush Hog Type Mower - by Francis Robinson. Looking around at my new neighbors, most of whom are city raised and have recently acquired their first mini-farms of five to fifteen acres and also from reading questions ask at various discussion sites on the web it is frighteningly apparent that a great many guys (and a few gals) are learning by trial and error and mostly error how to use a very dangerous piece of farm equipment. It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
