Where can I get a good price for a new unit?First do you have exceptionally cleaned area to work on these? They require a dust free environment as any can damage the new parts. Exteriors must be spotless ie all dirt and other debris removed.
Now on a recent job it would have been $145 less than a complete unit and that don't even count my labor to rebuild a Hydro Gear transaxle. I only get a 30 day warranty on the parts but get six months on complete units. And that is because I am a Hydro Gear authorized repair shop. MY distributor would not even warranty the parts or whole units; unless, I was a HG dealer.
When come to rebuilding these unit it is like rebuilding small engine it is just not cost effective anymore for repair to do this work. Now where Bert is it can be cost effective but in the US it is just not.
And as Bert mentions a lot of the time on riders; not ZTRs, The belt has a plastic idler that has to change whenever changing the drive belt. Wear on it is the same as if you install belt that is too long and allows the belt to slip.
Are you pulling anything in a somewhat regular basis? Are you running mower at wide open throttle whether or not when blades are on when moving mower? Exactly how not flat is your property? Is hydro transaxle free of dirt and debris?Mulligans seem to be not only a good price but honest and offer good information on the commercial viability of repairs and even upgrades .
I always run the mower wide open when cutting but when I stop I turn off the blades and I put the engine at idle. I do not pull anything with the mower. I have a golf cart to pull a small trailer. See pix for the property. I do not have a lot of dust while cutting the grass--just a lot of grass clippings, which I vacuum off after cutting the grass.Are you pulling anything in a somewhat regular basis?

You said you have been through three units in 17 years. That is a new unit every six years, which seems very unusual to me. I have seen mowers with working hydros 20, 30 years old and older. If you can buy a Hydro Gear unit for around $800, that seems about right.
I sent an email to get a price for the Hydro-Gear 400506 356-0510 Trans axle. The reply was--NO LONGER AVAILABLE! I assume that they still have some parts???Mulligans seem to be not only a good price but honest and offer good information on the commercial viability of repairs and even upgrades .
So you send them another email asking what you can do to get around this .I sent an email to get a price for the Hydro-Gear 400506 356-0510 Trans axle. The reply was--NO LONGER AVAILABLE! I assume that they still have some parts???
Yes most of the parts are still available. Here is the IPL for the HG 400506I sent an email to get a price for the Hydro-Gear 400506 356-0510 Trans axle. The reply was--NO LONGER AVAILABLE! I assume that they still have some parts???

Not the op, but I just learned something here! Why is this not in the owners manual? For years I thought I was just cooling it down for the ride back. And lowering the noise too, a double win! Lol, live and learn. You guys are the bestI see now where there was a post someone saying they mow and when they get done they turn off their blades and lower the engine speed to idle. This is just asking for trouble so everyone needs to stop doing it.
Just because one, or a few people have been doing it for decades on multiple machines and have not had any transmission failures does not mean it's not bad on the machines. It's a terrible practice.
Just like people who tout synthetic oil in their car saying I got over 250,000 miles on my car and never had any internal engine repairs....
Well, guess what?? You could have probably used standard mineral oil and still had 250,000 MI on that engine because car engine simply got a whole lot better over the years up until recently.
They make claims and statements like they are scientific fact but there has been no scientific method or laboratory or actually controlled test done at all so their specific experience means nothing and forecasting the future or for others.
Hey Fred. If that one was made by AYP or Electrolux, you can probably find a parts tractor somewhere with a geared typed transaxle. Most of the Poulan Pro 54" cut tractors were gear type transaxles. They look like the old Sears Suburban cast iron units with the high/low stick but they're aluminum. Should be a bolt in swap, clutch pedal too. Just an idea if you're planning to keep your current tractor. Pretty good gear type rear ends.I went to the Sears Parts website. I got into their chat and they said that they have the trans axle. The cost including shipping & tax would be $826.46. So the situation that I have is do I buy a new unit or do I try to rebuild the unit that I have??? I actually have two units at this point and one other unit that is all apart. Decisions, decisions!!!
Thanks for the info. When I first got this mower I was going crazy up the hills way over 15°. Needless to say the trans axle didn't last too long doing that. After having the trans axle replaced under warranty I stopped running up the hills. But I still have some inclines to mow. At this point I am actually following your suggestion of going down the hill and not up. (I have been doing that even before I read your suggestion--glad to see I am doing sometime right at this point).on a hunch here... at what altitude is your property for this mower?
high altitude...rich mixture..low power....low power = premature hydrodrive wear?
noting: for every 1,000 feet of altitude of elevation above sea level, the typical gasoline engine will lose about 3 percent of power...(less oxygen...not enough bang). example at 5,000 feet ASL = 15 percent loss of power. Mower engines are generally designed to handle some altitudes without significant issues BUT hydro drives are particularly sensitive to POWER (and not necessary RPM..which is how most people think of when they say things like ...don't idle your engine when in motion...keep it wide open throttle. Most think this is a factor of RPM...because that is how it is relatable...but actually when dealing with altitude...where oxygen is lower in percentage...you can be operating at wide open throttle at 3400 RPM (that's usually the governor max rpm for most mower engines)...at sea level...that best torque and power...however, at 5,000 feet ASL...you are still at 3400 RPM...but it's not nearly as much "umpf"..it's less power. And this can definitely be a problem for hydros, especially on large mowing properties THAT INVOLVE INCLINE/DECLINE...hills, slopes.
there are a few tricks that the old school engine mechanics can share to help improve power even from a naturally aspirated carb mower engine at altitude....but I would not be the guy to give you the 1-2-3 on that. I've heard about a few mechanics tricks...mostly from high altitude chainsaw gurus. I'm not sure how easily it would be to modify a mower engine for altitude though...I'm sure someone has done it
other comment: generally speaking higher quality longer lasting, more powerful hydro drives have large cooking fans, serviceable filters, and oil reservoirs so you can inspect the condition of the oil..you not only get better power, but top speed. Everything internally is usually built with higher quality components and manufacturing processes.....especially the 12 mm drives...the 10mm drives are pretty much what you find in the home owner to middle prosumer...the commercial grade stuff is 12 mm drives...and at least a 25 HP twin needed to power them AND mow at same time. ...That might be what you are dealing with: cheaply made hydrodrives...that you've replaced them three times kind of points to a a trend suggesting just not well built and suitable for your application. Moving up to a commercial grade mower based on a commercial grade hydro drive is going to make a difference. At 800 a pop and the time down to replace must be frustrating.
also: One technique for driving mowers that I have found works well to help extend the life of hydros...no jerky movements...long slow radius turns. and no sudden stops or quick reversing...I know this sound silly because they are designed to turn on zero...but when you put a great deal of force applied in a short period of time, like full forward to full reverse very suddenly.....that really heats things up quickly...all those bushings, bearings, valves, races, passages....they all get beat really hard. This is especially true on hills..both going up and going down. I take a long line and try to avoid turning quickly at the top and bottom and working the mower hard in a hill in a short period of time.. I put the hill INTO a large pattern...like the hill next to the house...you cut that and then keep running up the hill into a larger pattern...and visa versa when going down...for very steep hills..I never go UP...Always driving downslope. it make a huge difference in load on the engine...600 pounds plus my weight going down hill requires far less power than moving that up the same hill. And whre you can, take a track that is steady gradual slope that leads to the top of the hill and then cut down the steep slope.....So the hydros and engine has time to cool off and I'm not at top torque all the time. I don't know if it really make a difference...But it's just something I do. Kind of how I have a 40 year old truck...I baby it. I know what I could run it hard...it's more than capable. But it's a 40 year old truck because I baby it. FACT. (yes, people hate me on the highway...lol...eff em)
and last comment (I promise): There is a specific after install air bleed procedures when replacing hydro oil and filters...it is the same process for installing new hydrogears...you really want to refer to the service manual on this procedures and don't take shortcuts. This is one of the benefits BTW with the higher quality hydro drives with a reservoir tank...you can see with your own eyeballs the air bleed process to make sure it is actually happening...bubbles and burbles...all of this is done unloaded wheels off the ground...make sure whe you ever service your hydros or replace them, follow this service manual process....it really does make a difference.
really beautiful property there...with a view like that, mowing must be some kind of wonderful...awesome.

For slopes like that you need a horizontal shaft mower and a diesel one to bootThanks for the info. When I first got this mower I was going crazy up the hills way over 15°. Needless to say the trans axle didn't last too long doing that. After having the trans axle replaced under warranty I stopped running up the hills. But I still have some inclines to mow. At this point I am actually following your suggestion of going down the hill and not up. (I have been doing that even before I read your suggestion--glad to see I am doing sometime right at this point).
Seeing that I am either going to replace the trans axle again OR buy I better mower. Do you have any thoughts as to a new mower that last a better trans axle set-up and is not 15K?
Here is a pix of the hill that I mowed in the beginning. (I don't mow that any more)View attachment 66045
upon seeing that incline and the size of it, I would not recommend an ordinary residential zero turn gasser. I think bertsmobile1 has the best advice...diesel mower..just realize that is going to be costly.Thanks for the info. When I first got this mower I was going crazy up the hills way over 15°.

If you wander over to mytractorforum.com and go to the forums, do a search for hydro. I know there were posts on that site referencing drain & refill and changing the filter. There was also a comment, from memory, that the filter MUST not be a generic cross referenced filter as the fluid direction of flow within the filter is reversed, so the media must be supported against pressure from the opposite direction.Does anyone know a company that makes a riding mower that has a better Trans Axle.?
Are there trans axles made that have a drain plug and a oil filter?
The Hydro-Gear 400506 356-0510 does not have a drain plug or a oil filter. When I first started having trouble I called Hydro-Gear and they asked if I had changed the trans fluid. I said no because the Sears manual said that the fluid does not have to be changed.
If I buy another mower I would like to have a drain plug and a oil filter on the trans axle!!!
Here is some additional info. First we start with a mower designed AROUND the best hydro drive.upon seeing that incline and the size of it, I would not recommend an ordinary residential zero turn gasser. I think bertsmobile1 has the best advice...diesel mower..just realize that is going to be costly.
another idea besides the shrubs and berry trees he has suggested is to landscape (dirt work) that hill side into a series of terraces. It would give you several benefits:
1. erosion prevention/ground subsidence prevention/better drainage and water soil conditioning
2. easier to establish plants, trees, shrubs/bushes...ground cover
3. aesthetics
there are so many different ways to build terraces. In very steep inclines, and where there is heavy winter snow or lots of rain fall, it is advisable to use large stone and plan the excavation carefully (or concrete/block is stone is not available in your area). The idea is to create leveled terraces with strong retaining walls.
it would definitely be a big project, but doable if you had an excavator and the retaining wall materials and the time. In this way, you can grow something other than grass that requires mowing...like a very robust garden...it would of course attract all manner of animals and game too.
I've done this for a hunting camp in North Louisiana, that was on a large steep hill. We terraced an area of about 700 feet wide by 300 feet downslope. We grow alfalfa and sorghum to attract the deer to the property as well as lots of other native species of berries. In the upper terrace near the camp, we planted a wide variety of bushes about 20 undercup oak trees to keep the top of the hillside stable. We did have to put in some drainage though. water will tend to accumulate in the terrace and that additional pressure can make retaining walls fail...
back to mowers. It's possible to get a good quality commercial mower for around 9K...but the diesel mowers are always going to be expensive. If you stay with a zero turn, look for hydro drives that have the 12 mm drives. And at least 25 HP. I would say as a general rule of thumb, if your elevation is above 5 thousand feet, invest in an Electronically Fuel Injected Engine (efi) for gasoline engines. A standard diesel engine should perform better than a standard gasser, and definitely will if it has a turbo, but at great cost. which bring the question: is a diesel tractor mower an option to explore ?
Thanks for your reply.on a hunch here... at what altitude is your property for this mower?

will only be replacing one problem with another...just my opinionOkay. I stopped by a local Husqvarna dealer and looked at at Husqvarna TS 354XD tractor.
Would this be a good choice for me to purchase? Or am I just buying a 5K problem?
