TYM 723 hydraulics heat up using remote float

[cowridermi]

I am using the float position on my remote when using a drum mower. The hydraulics heat up to the point that engaging gears is delayed. I have 700 hours on the tractor. My understanding of the valve is that the fluid should flow through the body the same as when in the neutral position so the fluid shouldn't heat up more that normal. The workshop manual shows the flow through the different positions. Is there an adjustment for the float? The manual doesn't show one.

Has anyone added a temperature gauge for the hydraulics?

Are you sure you have a float function on the remote and not just a detent that holds the lever in place? Technically, it would give you the same effect as float, although the oil that should go on the opposite port is now getting forced to go through the relief valve and back to tank. This creates an insane amount of heat.

Both the parts and service manual show this as a floating detent.

Cylinder seems to float in this position. I went and attached a open hose on each port and started the tractor with it in float with no oil coming out. I may be chasing my tail with this. Need to set up a gauge to watch the temps. Engine stayed normal, just the hydraulic seemed hot.
