What is the highest HP Kubota farm tractor made with a Hydro Trans ?

[Brown Dog]

A homeowner or cattle farmer doesn’t need precise ground speeds.

Lots of other applications needs a certain trans option capable of running exact ground speeds.

Most 6 8 & 12spd trans have Big Gaps between gears not allowing this.

which is why M series offers creep gear option

Depending on your fabrication skills you could build a custom tractor with HST tranny potentially using a tractor that has a frame supported engine and tranny. Need the frame since would effectively be removing the transmission and replacing with HST.

Could use either Danfoss H1 series pump and motor or Rexroth A4VG pump with A6VM motor.

Suspect reason no one makes one is limited demand vs development cost.

Do you need a PTO? If yes that would potentially require a thru drive on the pump capable of required torque.

If ALWAYS going slow could possibly get by with fixed displacement motor vs variable. Would save a little cost and control programming.

Probably not simple and inexpensive but necessity is the mother of invention.

I couldn’t see building one.
I need 8-12mph for travel to the shed to dump litter.
Also need 4wd AND PTO.
So no go on self build.

All of those are possible but at what cost.

Agree probably not feasible for a one of build for a nasty corrosive environment.

How heavy a tractor are you looking for to fit your application?

Having many speeds under 1 MPH is very specific application for sure. Most utility tractors are lucky to have one gear 1-2 MPH and need creeper trans for rest. I have cattle and make hay and I agree I don't need to worry if I have exactly 5 MPH or if it's 5.1 MPH, I just care I have decent selection of field speeds in the 4-8 MPH range. Gaps between gears get annoying, I ran one baling that 2nd was too slow and 3rd was too fast.

M7060 12 speed creeper has 6 speeds 1.04 MPH or less, but that isn't enough selection for OPs application.

good post. i do not need the option, but buyers should know that the creep gear op is not intended for FEL or ground engagement implements, just for speed control for seed drills, etc. you already know this as owner, but many i'm sure would like to use them for harder work. regards

I’m so glad JD doesn’t mention this
I’m pulling 15k lbs in creep 4wd when loaded in the houses. Flat ground tho
