Slack or disconnected brake linkages can potentially apply some brake, especially with the tractor heading up slope.I confess I didn't quite follow the parking brake comment. I get tying it, and checking if it will spin a tire, but that was while flooring the pedal.
I'm not sure how you check the parking brake, as it relates to this.
Also, davescarp, in the other thread, you had mentioned that you were going to get the different (higher viscosity) transmission fluid. Did that fluid change anything?
haha nope, no filter on the x500's. no external hydros. kind of like everything being manual but it's all I've been used to. manual deck lift is easy with the assist spring set correctly, and honestly the manual steering is a piece of cake too, but I can see where power steering would be nice.I'm hoping you didn't stick a filter in the x500 it doesn't require one! just thought if you did who knows what that might do to oil flow!
I've never opened one of these units up or looked at flow schematics [if there is one},but I assume the charge pump is what pushs the fluid through the filter! I was thinking without a charge pump in the unit and putting a filter in the hole might allow the filter to travel where it "would" impede flow!I won't do anything to the flow. It just sits there submerged in fluid.
Check the linkages and connection to the transaxle. My 345 was doing the same thing and I found a roll pin about to twist in two.Detailed in another thread, but I have a x500 with <400 hrs that is exhibiting all the signs of a bad transaxle. I've replaced the fluid, drive belt, pulleys etc. with no change. I bought it used from an older gentleman who bought it used so not sure what's it's been through in life but it has 386 hrs so not too impressed either way. I mow my semi hilly yard, move a little snow (do most with my truck), haul some mulch, your everyday suburban ****.
My options are wait 4-6 weeks for my Deere dealer to tell me they need to replace it for >$2000 (yes 4-6 weeks), buy a used K72 with unknown history for $8-900 on ebay and strap it on, or drop $400 on the rebuild kit do it myself. I just watched 12 hrs of youtube videos and it's not as daunting as I thought, but haven't seen a video or tutorial on a k72 proper. This would be the first transaxle I've worked on, but am reasonably good at following directions and can read and follow a schematic well.
So, should I do the rebuild??? or just sell it as is and recoup as much as I can out of it? I have the 48" front blade/plow and a power flow for it, so have a bunch in vested in the x5xx series platform right now... Here's a pic of the offender, because pics make every thread better.

So yeah this trans gradually started losing power going up a moderate hill, and would make excessive noise in doing so. Conditions got worse as the unit heated up. Has 375 hrs on it but I suspect that may not be entirely accurate.Cool, good luck! Remind me, the other thread that was mentioned, was that a discussion about it (suddenly?) being unable to climb hills? I'm not sure if I'm thinking of the correct thread.
What have you found so far? Any "smoking guns", of stuff that seems worn or damaged? Just for curiosity, can I ask roughly what the repair/rebuild kit cost?
I'm a bit envious of you Tuff Torq folks Searching YouTube, etc, for hydro rebuilds shows quite a bit of Tuff Torq results, and very little for Hydro Gear, unfortunately. But even this one picture is interesting, thanks. I presume the canister in the upper center is an internal oil filter?
