Oil & Fuel B1550 HST Hydraulic Oil change

[kld2760]

New member here... I'm trying to do a complete maintenance service on my dad痴 B1550 HST Kubota. It has not been serviced in over 3 years since he passed away and I want to get it in tip top shape. So far I have changed the oil, oil filter, fuel filter, replaced the gear oil in the front axle, greased all the grease points and replaced the coolant. I am currently trying to replace the hydraulic transmission fluid.

I found 3 plugs on the bottom of the tracktor; 1 right under the front PTO and 2 on each side of the rear axle. When removed the HST oil filter I can tell that not all the hydraulic fluid has been drained. Also, the HST dipstick shows a considerable amount of hydraulic fluid still in the transmission. Does anyone know of anymore drain plugs for the transmission fluid? Any suggestions? Thanks!

You have them all and don't forget the suction screen on the left side. Can't think there is any oil left if all the plugs are out.

We had a B1750HST and there were two strainers,one on each side in the rear.kuboman pretty much said it,you should have it drained.Pull and clean the strainer(s)for sure.Good Luck!
