Hi all the Massey Tractors use Auto trans Fluid or a good grade Hydraulic Fluid
If you are in a very cold Climate I would use Trans fluid it is thinner but if you live in a hot climate I would useTractor transmission Hydraulic fluid but it is up to you I use Chevron tractor transmission Hyudralic in all my tractors I have four MF & two Case the Chevron # for it is (T H F 1000) Let me know if you need any more info
For my 202 I just use regular power steering fluid. Normally I just pick up the cheapest stuff the auto parts store has. Only use it for power steering though.
