What is the difference between a syncro-range 4020 and a 4020 powershift? Which one is better. Thanks.

I don't like the power shifts on hills for when you are on and off the tractor alot (like loader work)The park doesn't seem to lock in solid sometimes and when it does you can't get them out of park. I don't like the power loss and lag in cold weather either. Came in handy one time I was pulling a semi truck up the hill and started out in too high of gear it sure was nice to be able to down shift under full power and load and not miss a beat. They both have there place.

I have one of each. Powershift is real nice for chopping and baling because its just so handy to bump it up or down a gear depending on how heavy the crop is. The transmision pump runs any time the engine runs so you wont starve your main pump on work with a lot of clutching.(loader or round baler) But most jobs I pick a gear and stick with it so the syncro is fine. You can tow or roll start a syncro. Change your filters and don't run it low on oil and a powershift will last the life of the tractor.

From the engine back, each is a totally different tranny.

The powershift gets slightly less fuel economy. It is nearly indestructable, but $$$$ to repair, if it ever does fail. The foot clutch pedal is connected into the transmission shift hydraulics, so there is no dry clutch to wear out. (There IS a clutch on the flywheel connected to a little release lever for cold-weather starting, but it seldom gives trouble.)

The synchro-range uses a dry clutch on the flywheel that eventually wears out when used a lot (loader), and the sychronizers and shift forks in the tranny wear out over time.

It's pretty much a matter of which setup you are comfortable with, as BOTH are pretty darn good.
