Hi All,

I just picked up a GT14 with a snowblower  to do my driveway. The guy I bought it from picked it up from a neighbor to repair and flip. He said he had all the hydraulic lines replaced. We noticed the snowblower would lift really slow so he kept adding hydraulic fluid (not oil, like clear hydraulic fluid from a gallon jug) to the reservoir near the battery as it bled out the air.

Fluid was added until the reservoir by the battery was full.

Now I am reading that it should have 5W-30, not hydraulic oil.

 Should I drain it all out and add 5W-30? 

 

Also, the manual states oil should be added from a plug at the rear of the transmission and that is how the fill level is checked. Is the transaxle overfilled?

1st off...welcome to the forum!

 

Is this a gear drive or hydro?  It sounds like you have a gear drive since you have the fill cup by the battery.  Given is a gear drive, you would probably be OK...but I would personally drain the system and refill with 5W-30 to stick with the specs.  A few quarts of motor oil is much cheaper than hydraulic system repairs.  If it's a hydro...I would definitely drain and refill with 5W-30.  The gear drive model has a separate hydraulic pump/system for the lift. The hydro model shares the hydraulics with the drive system.

Thanks Billy, I am assuming hyrdo by the spool valve and hydraulic lines.

This is the spec sheet according to the model number. Looks like it does take 5.5 quarts of 5w-30.

Yep...that's a gear drive.  I have one just like it.  The hydraulic pump is belt driven off of the right angle gear box above the transaxle.  The aluminum tank with cooling fins is the hydraulic oil reservoir.  There is a drain plug on it to drain.  I think there is a plug on top to quick fill if I remember correctly.  Remove the tunnel cover to access the top of it.  You can top off with the fill cup after that.

The spec sheet you linked to clearly states  "Transmission:4-speed gear" Which indicates a four speed manual transmission, not a hydro static transmission. That is a very nice machine and deserves all the love you can give it. If I had it I would make sure I had the machine correct manual and read through it from beginning to end. Then follow the manufacturers suggestions and instructions as closely as I could.   "The guy I bought it from picked it up from a neighbor to repair and flip. He said he had all the hydraulic lines replaced."  Does not give me a great deal of confidence in the skills, ability's, and concern for the machine of the PO. Don

Thanks for the info. It looks like the original owner took really good care of it, became unable to use it, and sold it to a neighbor who only had it for a few days. 

  Looks like I will be draining that finned reservoir and filling it with 5w-30.

Welcome to GTT. Check our Manuals Section for the manuals that you need. Now, you need to find a cab for it. Good Luck, Rick

Is the fluid in this reservoir separated from the differential or do they share fluid? Still trying to figure out how this works.
