Hi Larry,
If you do a search on here for Multi-Power there are plenty of explanations. Simply through the use of a hydraulic clutch the number of forward gears than you have are doubled to 12 forward and 4 reverse. There are benefits but also one drawback that you can't tow the tractor to start it.

Multi power is simply an direct drive/underdrive switch..... multi power in high engages a clutch pack that direct drives the engine into the transmission...... low multi power has a slight gear reduction (not quite half a gear), and gives you no engine braking (will coast down hill even with clutch out).

Another drawback is you have no engine braking in low multipower. I knew of someone who was rotovating in low multipower ( With a 65 I think )and the tines bit into a bit of compacted soil and it pushed him into a ditch! On the other hand it is very useful to have twice as many gears (For baling for example )

larry,

better take that thing out to a hill with a nice gentle landing area and be sure the m/p works.

if it not working correctly it will take off down the hill and the brakes are all you are going to have to slow you down.

be sure your brakes are in top condition.

this thing can get away from you on a hill.

i know some old farmers that used them for years, but would not let kids drive them as they did not know the trick to stop them on a hill.

As the previous contributor's have stated, the "multipower" optioned tractors were a wonderful machine to operate, WHEN the multipower was working correctly, and the operator had been briefed and was schooled up the benefits of this type of transmission.
And, as has been said already, they were a bugger of a thing when they failed. Multi-powered tractors got a bad name for this reason, and the most common problem causing an initial failure of the transmission to work as it was intended, was because the suction filter on the hydraulic pump supplying oil for the clutch pack, would often "choke up!" This primarily was caused by ingress of water in the oil, via failed gearshift and draft plunger rubber "boots", and, of course, the inability to be able to "service" the filter regularly.
The filter was neatly "stashed" away, inside the diff centre housing, requiring removal of the hydraulic lift cover, to access it for cleaning.

my two cents worth,
Evan.
