F18D control

[Lee-HT]

Under the seat on the right side is a slot in the sheet metal. There is a M6 stud coming from underneath. This stud is on a bent bar about a half inch wide that connects to a small rotating plate with a M3 shaft going down into an upper part of the rear housing. When I move the stud toward the front it rotates the M3 shaft and slows the engine down about 400 RPM.
The Murray Owners manual shows it as a 4WD but it doesn't engage the 4WD. That lever is low left of the Tran housing.

What is this?

that could be the low range control. have you tried using it? does it slow the tractor down?

Never mind. I looked so more.
The rotating shaft is a control that sends fluid to another box under it that has a HYD hose coming out the back that is looped back into the same box. This can be used for HYD attachment like maybe a tiller?

Thanks anyway.
