3020 Diesel - tank for front hydraulic pump?

[Tx Jim]

These were all pretty good tractors in the day, wish I had them now.

IIRC the model tractors you mentioned with sycro-range had a hyd reservoir but powershift trans models didn't. Reason being PS trans pump pumped oil all the time engine was running while depressing foot pedal with engine running stopped SR trans pump. In today's world a low hour 4020 PS will bring a lot of $$$$$$$

According to the gospel of Deere CTM-7, page 01-8 .
The 3020's were built with the 2000 series front pump. Either the 40cm3/2.4 cu" rated at 23gpm at 2500rpm. Or the 50cm3/3 cu" rated at 30gpm.

50cm3/3 cu" rated at 30gpm pump only came from factory on a HFWD model tractor
