Slopes

I don't know about how long in minutes, but no longer than it takes for the oil to drop down to the low mark on the stick. What you could do is check that it's on the full mark (running of course) at the bottom of the slope, do one run to the top then look in the clutch compartment to see how much oil has come through. If that's too hard to see, then take a pan and drop the flywheel housing bung and see how much comes out. That will give you a good estimate of the per-run drain-through, and from that you can figure how many runs and thus how long you can run before you need to stop and replenish the engine oil. If one run doesn't produce much or any oil, then do two more runs and check, then four runs and check, and so on. You'll get a good idea following that procedure. I would be very interested to hear feedback from you on this topic with quantities, slope, distance, time, and gear you were in.

Hi It was something we never worried about when we were working the steep hill country in Nth Canterbury NZ just got on and did the jobworking 30degree slopes in 1st gear uphill for 150 200 yds always kekt the sumpfull and we would either throw out or burn up to a pint a day and when I say 1st gear going up these slopes you had to keep pulling the clutches or you would get bogged I would have no worries about it we always had the flywheel housing bung out never used in water so didnt know if the oil was seeping out or not its getting steep when the oil runs out the breather

Lot of orchards cultivated up and down slope here in the old days. Never heard any stories of loosing engines from from running out of oil by it running out going up steep. But my person experience is all D6.

The only oil loss I ever had was angling up as steep as the D6 would go with out spinning or sliding. Got the top track on a big rock (no traction at all) the bottom side was spinning and kicking dirt out fast. As I hit clutch a big glug came out the engine breather on the low side back of engine. To busy worrying about other things to look at oil pressure gauge. Backed out of the whole, turned down hill, got to flatter spot had psi and needed about a gallon to get back to full. Just because some of this ground has been farmed for 60 years doesn't mean it should be. In this case it was running out of top soil. That walnut orchard has since been bull dozed to make a vineyard. So now some untrained Hispanic is trying to get over it with Fiat/ New Holland crawler no doubt. Probably as sidling as I have ever been.
