Well.......................this isn't good

8 hours on my tractor. Half of those were operating the back hoe. Yesterday it would not go forward while in gear, reverse worked. After a few back and forth shifts forward starting working again. Today it did it once then fixed itself. I was moving a small pile of dirt going forward and backward then forward stopped working again. Tried L M and H. Reverse works but no forward. The engine will rev while in forward but no movement.

The selling shop says they will come pick it up in a day or two.
This really blows.

Fluid level?

Fluid level where? It isnt leaking. Tractor in parked underneath a car port with fresh gravel no fluid anywhere.

Sometimes, on a HST selector, the position doesn't 'quite' go into the actual selected position (I hope that that made sense).

I've found with my HST 4105 that, when your situation occurs, I'll hold the selector towards the desired 'L' or 'H' and apply a bit of acceleration and it will pop into the actual position. You'll be able to feel the selector engage.

Is this a shuttle shift or HST tranny? If shuttle it could be something to do with the clutch pack engagement command. No clue if HST though.

Wagtail,
It makes perfect sense. But reverse works so the trans is in gear. L, M, or H, reverse works. No forward speed works. Transmission oil is good.

It is a HST tranny.

It is possible they forgot to refill hydraulic system after installing backhoe, it takes a fair amount of fluid to fill all those cylinders on the hoe, if they forgot to refill tractor back up it could be all that is wrong.

IF HST have you tried looking at the linkage between the pedal and tranny? My simple mind thinks that if goes backwards it should go forwards.

Trans fluid level is fine. Anywhere else to check? And it worked fine for first seven hours.
Not sure I understand the linkage. Two pedals, left is forward right is reverse. Both are connected to the same linkage rod. Push reverse pedal and tractor goes backward. Push forward pedal and engine revs up. Linkage rod moves the same direction regardless of which pedal is pushed

 

[oldnslo]

On every HST tractor I have been around the linkage connected to the tranny moves one direction for forward and the opposite direction for reverse.

When you state pressing on forward the engine speed increases is the HST linked to the throttle on your machine?

I will admit I am not familiar with Kioti but I would be surprised if they are much different than Deere, Kubota, Branson, etc.
