Please explain " multi power" and how it works

K.Campbell · Sep 7, 2022

I had a chance to buy a TO35 with multi power and rear diff lock. I was told that the multi power wasn t a great option but the fella couldn t explain how it worked. I have no experience with that option so I m asking for future reference.. tell me all you know about that particular option.
Thanks

In simple terms, it's a power shift. Move the lever to high, and you go faster. Move it to low, and you go slower.

You'll find that the tractor will shift more easily in low. Sometimes when it's in high it keeps pressure on the gears if you're not on perfectly level ground.

Probably most important to remember is that there's no engine braking in low. If you're going down a slope you have to keep it in high.

So is this function prone to going bad? If so how hard is it to fix? Are parts readily available? Thanks in advance

This will explain it better. http://vintagetractorengineer.com/2009/01/how-does-massey-ferguson-multi-power-work/

Yes, they can have issues if not used properly.

That would be a rare find (if it was ever offered), or an aftermarket
conversion.

It has 2 gears shifted by a hydraulic clutch pack and an overrunning sprag. In high the clutch is applyed to the high gear and it is over running the low gear sprag. Release the hydraulic clutch the sprag is
no longer overdriven and now transmits the power.

My dad had a power shift 35 I drove it allot Low range was the same the nonpower shift tractors high range added about 5 mph to road gear.
