How fast was the machine going before? How old is the machine? Does it have a speed up kit installed? What position are the control rods in(fast or slow)? Also if it is older, check the clamps that go on the pump shafts. The old style of clamp can wear out leaving alot of play there so very little movement gets to the pump. The new style is much improved.

Have you checked the fluid level since bleeding? Did you just drain the tank or did you remove all fluid from the pumps, motors and hoses? Are you using a Wright filter or something from a auto parts store?

a plus bob,

I does seem unusual that the speed drop happened after only changing the fluid. The older Standers after serial 12000 had a top speed of 8mph, so this change seems drastic. Check to make sure the pump lock valves are fully closed, make sure oil didn't get onto the drive belt (causing slippage), if the oil is to thin a grade it's possible its pushing right past the bypass valves. What oil did you use? Is the system making any unusual noises?
