Loader in float position?

[freewheel3]

Here's a question that just occurred to me. My MX5000 is stored in an unheated shed.
Will the hydraulic oil warm up quicker if I put the loader in float position while the engine is warming up prior to driving?
I'm not sure how the hydraulic flow pattern is on this particular tractor but I remember 40 years ago when I was running a bulldozer, on the first start of the day in the winter, we used to always throw the blade in float while the engine warmed up.
This seemed to get the hydraulic oil warmed up quicker, but it was a seperate system, not a combo transmission / 3pt / power steering / hydraulics like my tractor has.

No putting the loader valve in float has no effect on the flow of the fluid, float only lets the fluid flow freely from one side of the cylinder to the other side.

Ok, thanks for the info, NIW.

How about the transmission in neutral? Any effect on warm up time, or better / worse in general?

tranny in neutral won’t change oil flow either, on an HST if you put the tranny in neutral then put the HST peddle down, put cruise control on, it will heat up faster.

Nope no real benefit to putting the transmission in neutral either.

I always just raise and lower the bucket, curl it in and out as I'm driving out of the yard. Seems to warm it up quick enough.

I have a Kubota L2550 with a BF400G loader and when I float the bucket the 3 point hydraulics fail to lift it's own weight. Just something to watch out for.

If you're using super udt2, there's no need in letting it warm up.

Most of the smaller kubota tractors are all open center hydraulic systems meaning that they're circulating fluid as long as the engine is running, thus it's warming up via circulation. Some of the bigger stuff is closed center, the pump is not moving much oil until it is asked to, thus they'll take a while to get warm.

If you want to warm up the hydraulic-/transmission-oil a little quicker, just let one valve function run against the overpressure valve.
For example, if you have an auxiliary hydraulic valve with a catch for one direction, use this during engine warm up.
Because of the little extra work the pump has to do, the oil (and the engine) warms up much faster.

That should help get cold oil out of the cylinders and hoses and replaces it with fluid from your warmed up tranny.
