You are watching: John deere hydro 175 drive belt
It looks like the lawn tractor has been turned on it"s left side in this referenced link to replace the belt.Small Engine, Lawn Mower, Snowthrower Troubleshooting, Repairs and SafetyTo do this, do we have to:remove all gas from the tankremove all engine oilremove all oil for the back gear (Hydro Drive)Not sure if I have the name correct for the last one, but we don"t have the manual as of yet.Appreciate the feedback.
Helped my neighbor change his 175 belns ,,,didn"t tip it on it.side , jacked it up and worked under it,,tipping it might be easier,,,,,take a picture or draw diagram before removing old a ,,,,,the belt has a twist in ins ,and it is possible to install it wrong and have 5 speeds in reverse and one in forward.:dunno: We had to remove the PTO clutch to get the belt installed.
Thanks so much for the reply. The mower was a donation for the church and the main belt was missing when we received it.Spent most of the day under the JD. Finally know that the PTO is the clutch and not in the diagram on the parts sight. It is shown on the 165 diagrams (10451)Was able to route the belt to the engine, but how did you get the PTO off? It just keeps spinning with the ratchet. Where would I find the diagram on how to twist the belt? Ordered the manuals, but they have not come.

The PTO is easiest to take off with an impact wrench, so as not to spin the engine over, like a ratchet will do. I"m sure other folks here will chime in on how they got the PTO bolt out w/o an impact, but I have not had to do it that way. You will have to unbolt the steering sector brace and turn it in line with the frame rails, and install the belt around over each end of that brace (straddles the steering shaft, basically), then thread around PTO and idler. After that it runs back towards the hydro unit, through the idler pulley (over the top of the one towards the front of the tractor, then under the next one and onto the hydro pulley) and then over the hydro pulley. There is a diagram somewhere online, of the view from the bottom of the tractor. I will see if I have the image of the tractor on it"s rear fenders when I get home tonight.I also have my tractor completely apart, so I can email pics out to. I just did put my belt on the PTO because I had the engine and steering out. It"s not yet on the hydro unit because that"s all on the bench still. Let me know if you need any pics sent to you.
