I serviced my GR2100 for the start of mowing season. The hydraulic fluid was low so I topped it off. A week later, when I went to mow, I noticed fluid on the floor. I assumed that I overfilled a little. I also did not use a funnel when I topped and spilled a bit. This tractor had the transmission seal update long ago. As I mowed, I noticed the the blades would bog down. I checked the fluid again and it was low. Added, Repeat. Then I saw the transmission was wet with fluid. Yikes.
I cleaned everything up with an air gun and rags. Filled and ran it. The fluid pooled on top of the hydrostatic pump, near the oil fill tube. I changed the tube o-rings and same thing. So I began to tear it down. It turns out the problem was the drain hose off the control pump. It's low pressure but apparently enough to leak like a sieve when the hose got hard from age. It's part number 10 in this photo.
I changed the hydraulic fluid while I had it apart. There was definitely clutch material in the fluid so now I am worried about the PTO clutch. Kubota parts lists a PTO clutch kit (K1253-94022). Does anyone know if this is the parts to rebuild the clutch or a drop in replacement? It looks like the clutch can be replaced without cracking the transmission.
