Setting a constant speed with a hydrostatic trans

[ellisco1]

Hi all,
Just got a MF 1749E with a hydrostatic trans. (Which I am loving) But, never having had a hydro tractor before, it dawns on me that there is no provision for setting the ground speed to a constant for spraying. I use an electric spray rig so I can run any engine rpm I want. I was thinking of adding a clip to hold the pedal in a fixed location and finding an rpm that gives the ground speed I want. Anyone else already solved this problem?

Doesn't it have cruise control?

Most HSTs have cruise control standard, or there is an option to add cruise control.

My 2720 is a hydrostatic. When I spray, I put the go petal to the metal and leave it there. I adjust my speed with the RPM's. Measure out 100 feet in a straight line and time yourself how many seconds it takes to run through it. Do the math and you will have a MPH/RPM chart for your tractor.

Or duct tape a GPS on the dash.

The 1700 Series tractors with HST transmission are as simple to drive as a car," says Bercik. "Two pedals by the operator's right foot provide easy control – one for direction, the other for speed."

The HST also offers advanced controls at an easy arm's reach. Max Speed Control adjusts the tractor's top speed, providing tighter control over a precise speed range. Response Control allows the operator to set how aggressively the transmission reacts to input, providing a personalized balance between comfort and power. Electronic Cruise Control enables the operator to conveniently set a constant speed without mechanical levers. And Stall Guard electronically monitors engine performance to automatically adjust speed for situational power to prevent engine stall. "These features, standard with the new HST, are bound to save operators frustration and enhance productivity," says Bercik.
