The multipower on my MF-135 is a gear splitter. It has a small ratio and fits speeds in between those of the 6 speed transmission. It is a planetary gear train with ratchet much like a IH Torque Amplifier. But some say its stronger. It can be shifted under load, such as when plowing gets tough and you are in the Multipower high range, it can be shifted to low range on the go, unlike all the transmission gears. It is hydraulically operated and there is a friction device on the multipower shifter that probably needs to be tightened to keep it from slipping out of high. I think I had to do that a decade or so ago. Other than the friction on the control getting loose and I think now the valve leaking oil inside the bell housing, I've had no problems with using the multipower on my MF-135. I do see more oil leaking from the bell housing after I've used the high range of the multipower. That's when that hydraulic system's pressure is present. On the fender of my MF-135 (right fender) there's a decal that shows the speeds for each transmission gear an HI or LO multipower. The gears go: Low range 1st low (multipower).
Low range 1st HIGH (multipower).
Low range 2nd low
low range 2ndd high
low range 3rd low
low range 3rd high
high range 1st low
high range 1st high
high range 2nd low
high range 2nd high
high range 3rd low
high range 3rd high. Its handy to start on in high range 3rd gear low to get up to about 12 mph, then shift the multipower to high and run it on up to 22 mph on the road, since the multipower can be shifted under load and without clutching. The multipower also freewheels without hydraulic pressure which prevents starting the tractor by pulling or pushing. It also acts as a hill holder in one range or the other. Its always easier to shift the main transmission with multipower in low. Gerald J.
