You could have one of two styles of tractor there. On one style, which I think is the later one, if you lift up the tractor seat you will see a reservoir about the size of two Coke cans laid end to end. On that style, simply open the cap and make sure the fluid is at least 1/2 way up in the reservoir. On the other style, there is NO reservoir under the seat. For those styles, look below the foot rest, in front of the left wheel and you will see a short length of tubing, looks like it might be solid, that is bent into a hook shape. Loosen the nut that holds that "Hook" in place and then add fluid until it reaches the little notch in the bent tubing. For my unit, I used an oil pump that I think started life as an outboard gearcase filler. Let us know how you are coming.

I'll have to check and let you know.

Type A transmission fluid has been recommended in the past. I went back and checked my source. The hydro itself holds 3 quarts, if you have the separate resevoir, it holds 2 pints. The source quotes the manual when giving the information. I've never gotten my hands on a Massey 12 owner's manual to make sure. Here is the topic, look down and find member DH1's informative post.

Yes, manual calls for Type A.

This is from an oil info site.

"It used to be so simple. There was Type A or Type F. If your automatic transmission needed oil, you only had two to choose from. Many Fords used Type F transmission oil while Type A was used in everything else. Today, there are several types of oil specified for automatic transmissions. Using the wrong one can cause shifting problems or even damage your transmission. Here are the more common automotive transmission oils used today.
Dexron Automatic Transmission Fluid (ATF) is probably the most common oil found on the parts shelves today. It used to be called Type A transmission oil but as improvements were made to the oil, the name was changed to Dexron. Many types of Dexron oil have been used over the years. The original Dexron oil became Dexron II, which developed into Dexron IIE in the early 1990′s. Dexron IIE used extra additives that helped clean computer-controlled shift solenoids and pressure control solenoids inside the transmission. After only a short time, Dexron IIE became Dexron III, which is still the current Dexron designation."

I once weighed my 12 G before loading it and several other items on a small trailer. Bathroom scale read around 150 each wheel without the deck, so I'd say the tractor weighs close to 700 with the deck.
As for reverse, I know that the cam limits the travel of the actuating lever in reverse, so you won't see the same speed in reverse as in forward, but you should still get up pretty good speed.

Thank you for the info she was low on fluid and now works well in forward shes pretty weak in reverse... is that common?
Thanks for letting us know. I've seen more than one thread simply end, and you wonder which of the solutions suggested worked.

On mine, the belt was slipping a little but only in reverse. Confused me, but that's what the problem was.

The piece that looks like a mini screen door closer, needed cleaned and then re lubed. I didn't take it apart, just hosed out everything I could with compressed air, brake cleaner, compressed air again and then some 10 wt oil. Made a big difference.

Both of my parts units have extra springs on that tensioner, so it must've been at least a semi common problem on some.

I have tried a few times but the download is in giberish just a bunch of funky numbers and letters
We've run into that a few times. Seems to be a mystery setting in Internet explorer.

Do you have another browser you could try? Chrome, Firefox, etc? Those two save the download in a file marked 'downloads' and opens them right up.

If you only have IE, is it giving you the option to open or save? If so, try saving, then check the extension. For some reason a few IE units try to save as '.html' instead of '.pdf'. You will get gibberish this way also. Just change the extension back to .PDF and away you go.
