: I bought a Long 3 pt. hitch backhoe and attached it to my Massey Ferguson 250. It is the type that has its own PTO driven pump with the hydraulic reservoir built into its frame. I believe that I have found one reason that these are not too popular - in continuous digging, the fluid and cylinders get hot and it loses most of its digging and lifting power. : I guess that I could re-plumb it and run it off my remotes for more fluid capacity. Does anyone know of another way to help this? Any comments on use of these backhoes in general? I have a Woods 650 3 point. I'm not sure how much bigger your Long is (mine has a 6 and a half foot reach and is mounted on a 20 HP John Deere Diesel) but the theory should be the same. I don't notice any significant loss of power on mine, and I fairly frequently operate it for 3 or 4 hours at a stretch in heavy clay and rocks. Mine has a tank reservior that holds about 6 gallons. After a long spell of hard digging, the cylinders do get uncomfortably warm to the touch, but she keeps on digging just fine. Two possible suggestions: Make sure your oil is full to capacity. Low oil will cut down on heat dissipation quickly. Make sure the filter is clean as well. Also, you might try a high flow oil cooler on the return (non pressure) side. One of the reasons I went with the self contained unit is that I was told that cycling the temperature on the tractor fluid can cause condensation and water problems in the trans. Also, my JD's built internal pump is too small. JD's integral hoes for the 750 are painfully slow to operate. You might want to check that out before replumbing.
