What is/are the benefits of hydrostatic transmissions ?
Original Message   Nov 10, 2010 1:48 pm
FWIW, I bought my 1st 2 stager - Honda unit - without ever demoing a unit that had Hydrostatic Transmission.
Just short of the fact that it's variable infinite speed, can anyone just give me a laymens primer on the benefits of a Hydrostatic Transmission ?


BTW, how often if any do you do a OCI on the hydro transmission.

I was just surprised how much ~harder~ is is to move when not engadged as opposed to ~regular~ geared transmission.
I was at the local orange borg last night and wheeled the Organge buckets around and they wheel so much with ease...

Great analogy.....I'm not thinking straight.

Augers are coming out today. I have a half day today ;)

Do you mind taking pics and post them online?  I'd do it myself but don't have the luxury of taking out half days to play with my toys.  :)

I'll try. Sometimes I get into the heat of the moment and just wrench on..

This time of the year is crazy...even taking 4 days before T day to prep, it's always a madhouse...

I'm trying to cram sealing/finishing the cedar, build shed foundation, trim bushes, build shed all between now and 10 days from now.
That is just on my short list of of to dos ----all thanks to this new red bucket of mine. Eeeks - Does that mean 10 days minus 4 days of Tday Prep = 6 days.

I think it's okay to shift from forward to reverse without declutching, move the lever to neutral slowly so you don't shock the drivetrain.  It's probably okay on ice or snow, since, the tracks or wheels will slip a little, but probably very abusive to the drive train on clean pavement.  Use common sense, you wouldn't want to pull the e-brake on AWD car to drift unless you like to get a new differential.



Actually you should be able to pull the e-brake to drift on an AWD car to drifty with no problem. You can see Ken Brock doing it in his videos. But You pull it just enough and then let it go.

I'd say the hydrostatic is similar to a cars automatic transmission. How fast do you want to be going forward and then jam it into reverse? On my 928TAS I came to a stop and then reversed it. I think reversing it while moving would be a bad idea.

I don't know what his car is set up is like, but I wouldn't do it on a normal car.  When you pull the e-brake, all the torque from the rear wheels goes to the front wheels, that sounds like driveline shock to me.

Yeah, how about pics of the blower / impeller and what do you need to take off to free it from the shaft>

It's easy as taking candy from a child....

Steps 1 and 2. Once you look at it in person you will understand.
Remove the support bracket.
Remove the Blower Shear Bolt.

Ah, yes, very easy.  Just looked up the parts diagram.

Actually, I tried taking candy from my one year old boy, wasn't as easy as I thought.  He put up a good fight.  I can pull him along the wood floor but he wouldn't let go of the candy.

If you are on dirt or even pavement you can yank the e-brake to start you into the turn. Many AWD cars don't like to drift. It sure doesn't hurt Subaru's but might wear the brakes faster but yeah you have to let off the gas when you do it. We have RallyX events here and you'll see quite a few of them doing that. The FWD's lke to rotate if you use a bit of brake.
