Thanks Ken. Both sides of the frame hold the hydraulic fluid, in the same cavity as the divechains and clutches arrangement. There's a plug/hole where the level should be filled to. It needs to be on level ground to check, which is difficult on my property. To access the tank I have to have the wrench, which is on order. So this is the next chore once I get the wrench from my dealer.
I used the Bobcat for about an hour today on that slope project. I adjusted the brakes again before starting so that I was less dependent on the clutches to hold it on the slope. Only one adjusts. I have to replace the adjustable tie rod to the other to allow me to shorten it up and get better braking. The brakes suck, and creak and groan and catch. But it was better going. You're right about the clutches releasing you downhill when in neutral - scary. And I'm afraid about burning out the clutches using them to hold the Bobcat stationary on the slope. Also wary of a power failure/stall and relying on the foot brake to hold me on the hill. Stressful, but fun, work

In any case, the leaked oil, which had mostly dissapated since the pic I posted, did not reoccur, so I'm positive it was the jerking of the Bobcat.
The lever travel is not consistent, and the rearward motion on the right lever snags/sticks. I have to pull hard back on that side to get the right wheels to reverse. I'm sure I need a clutch adjustment, and again am waiting for the tool to do this. The user guide seems clear about this procedure.
I'll take some pics this weekend when the rains stop and post them.
Thanks Ken,
Stephen
