I know it is not best practice to push a hydro around. I've searched owners manual I printed from this site, as well as tranny manual....it seems it's on the left side but actual location is vague to me. I have a 73 16h hydro. The no name year I believe.

 

any help would be appreciated

thanks

Take a look at item 6 on page 5 of this manual

Sunstrand Hydro (part 4).pdf

It is under the seat on the left side top of the trans and will require a 1/4 turn, may need a pair of pliers.

180 degrees is the dictated amount to turn.

 

make sure when your done you return it to the original location. Otherwise you will end up like me thinking you did not connect something correctly. DOH !!!!

If a 16 Auto...no-name year (1973), the push / tow valve is on the left side.... It looks like a BIG SLOTTED screw.

It's harder than %^&*#! to get to, I know that.  :-( Very poorly engineered IMO.  I was fortunate that mine wasn't' frozen up.

Turn the PUSH valve clockwise until it bottoms out.

Is it possible to weld a tab to end of this valve to aid in operating push valve. I haven't yet had the need to push the tractor, but have tried to open valve and it seems to be frozen

The heat from welding could damage the O-ring and the plastic backer ring then you will have more problems.  Soak it with your favorite rust breaker over a period of time..tap it and try again.

Ah good thinking, wasn't considering any of the seals 

its not a very practicle design for easy operation. You shouldn't need tools to release pressure for pushing or towing

      Towing Valve Malfunction Sundstrand 90-1136 ‘69 Charger 12
      By BrianKoch
      Gentlemen,
       
      According to the hydrogear transmission manual, the tow valve on the ‘69 Charger 12 with the Sunstrand 90-1136 is “malfunctioning” because I am able to roll the tractor while it is closed. 
       
      To note, the parking brake pawl also seems to be broken, but I believe these issues are independent of one another. 
       
      Have any of you dealt with this issue of a malfunctioning tow valve before and can advise? I’ve got the ATF drained out and would like to address this before refilling. 
       
      As of right now, I have removed the tow valve and attached a picture of it. The O ring and nylon washer look fine to me, but maybe you see or know something different.

      Bypass valve leaking
      By Thatoneguy
      So I washed my rear end and sundstrand 90-1136 and now the by pass valves leaks when I screw it in past a certain point.  If I screw it all the way in I can sit there and watch the fluid start seeping past it.   I changed the o-ring with an R-04 i believe is what it was.   Do these require some sort of thread sealer? There was nothing on it when I took it out, and when I used the valve to push the tractor in my shop it worked fine and has never leaked. Any ideas would be wonderful!

      Hydro lost pulling power
      By TonyI
      I have a 418-c  worked great plowing over the winter.. but now is having no power pulling a load fwd.
      replaced the fluid.. the old fluid didn't look bad. feels a littls better., but still significant loss of power and high pitched whine coming out of the hydro.  the lift works fine
       
      is there a repair manual our there for the hydro?  Is there a way to reverse flush the system?   I hear sometimes the hoses crack internally and clog things up.

      Complete Pedal Kits for Hydrostatic Wheelhorse / Toro Tractors
      By mattd860
      I have developed a kit that allows a Wheel Horse / Toro hydrostatic tractor to be operated by a pedal on the right side of the tractor. The original forward/reverse lever can be retained or removed. The kit includes everything needed to install the pedal kit and installation is simple with the help of a downloadable installation manual. Additionally, only one (1) 1/4" hole will need to be drilled which can be done by a hand drill. No other drilling or cutting will be necessary. Any tractor with this kit can be converted back to stock without any visible evidence that kit was installed. However, you'll never want to do that

      The kit operates very simply and similar to modern tractors. When the pedal is pushed forwards the tractor will move forwards. When the reverse pedal is pressed downwards, the tractor will moved in reverse. If the operator takes his foot of the pedal at any time, the pedal will automatically center itself and the hydrostatic transmission will return to neutral (stop). This enables the operator to use both hands on the steering wheel or one hand on the wheel and the other operating an attachment like a snow blower, plow, etc.

      The foot pedal is custom cast in Aluminum, uses brass bushings to minimize wear, and it closely matches the OEM Wheel Horse BRAKE pedal commonly found on 8-speed manual transmission tractors. Modifications were done to the pedal to add the reverse pedal and adapt the pedal to the rest of the kit. For the most part, the pedal looks like it was designed and manufactured by Wheel Horse / Toro. Additionally, a grease fitting has been adapted to the pedal to further minimize wear and tear and if the brass bushings ever wear out they are fully replaceable without having to buy a whole new pedal. 

      The pedal kit fits the following series tractors with Eaton hydrostatic transmissions: C-1X5, 300, 400, 500. 
       
      My kit can be adapted to older hydrostatic tractors with the Sundstrand transmission, however, you will need to find an updated hydro cam commonly found on ebay. Message me for more information. 
       
      Here is a link where you can download the installation manual: CLICK HERE
       
      I am selling these kits for $330 shipped to anywhere in the United States. I offer multi order discounts as well. I will also sell to other countries for additional shipping charges to be determined.
       
      If anyone has any questions please feel free to PM me or post your question here and I will be glad to help. Or you can email me at mattdarling02@hotmail.com.

      Thanks!
       
       
      Below are pictures of the complete kit and the pedal installed on the tractor. Some modifications have been made since these pictures were taken. For example, the reverse pedal is now cast in aluminum instead of the steel pedal shown below.
