eroclb: PLEASE get a manual before you operate this very much!!!! The knob your twisting on under the seat HAS NOTHING to do with the hydraulic pressure. It is the rate of drop valve for the three point lift. IF you have tightened it in then you may have damaged the valve. If you have it wide open then nothing is damaged but it sure will let things on the three point drop fast!!

For heavy stuff you will need it turned in most of the way.

Pop always dreamed of having more acreage out in the country where he could retire and tinker as much as he wanted and often reminisced about his boyhood days on his grandfathers farm in Montecello,
