730 tranny oil level check

I"m still having trouble. I"ve posted twice on here and saw someone else post once on this issue. I"m wanting to know how/where to check the tranny/rear end oil in a 730 row crop. I"ve looked on the left hand side of the tractor around the transmission by the brake drum and on the axle housing but have been unsuccessful about finding a check plug or a 3/8" square headed plug. I really need to check the level before i start spring plowing with it. Any help is appreciated.

Thanks!

Thanks!

Those tractor models are also masters at mixing oils and makeing oil levels raise where you don't want them. As a matter of fact I'd be more surprized if it didn't mix engine oil in the tranny and tranny oil into the pto because the oil seals get really hard after all those years. That heavy gear oil in a pto is hard on the pto clutch facings. If you drain it you should find 2 drain plugs 1 is in the botom center of the case kinda below where the gear shifter area is. The other should be offset a little and back under the rear axles you may need to move the drawbar over to get to it.
