Need some help on LX176 with hydro static drive. It will not climb slight hills and slows down on level grounds also. I replaced the belt which was wore out but mower still slowing down. I adjusted the linkage on the drive which seem to help for a few days but back to doing it again. Need help please. Jeff |

if you can rule out the belt and linkages to the trans then it is probably
internal. before you go and rip the thing apart try changing the fluid, if it is low or contaminated it can effect the performance. If you change the oil and know for sure the belt and linkages are not the problem and the unit still has low or no power (or loses power as it gets warm) then the pump may be damaged, at that point I would take it to a pro and have it check. |

When I start out using the mower it seems ok then it looses full power after
30 minutes or so. Then it goes back to full power. It comes and goes during use. Is there disks that can be changed on the drive, that what it appears to be on the side of the transmission.

I am not sure of the style of hydro you may have in this JD but the only
disc (on the out side) I know of on your standard lawn and garden tractors that are a hydro trans is a brake disc which unless it is binding and putting excess load on your unit wont be the problem. Start by changing the fluid (and filter if it has one) as contaminated fluid and or low fluid will give you poor performance and possibly effect how it operates. Also make sure the outer case of the trans is not all packed up with grass and or dirt causing the unit to over heat, if there is a fan (I can't remember seeing one without a fan of some sort) see if it is broken or missing also causing it to over heat. If changing the fluid don't work and the belts and linkages are fine and it is not overheating then you can either attempt to repair it and take apart the pump and or trans axle but I do not recommend this. Only attempt this if you have the proper work place that is relatively dirt free to prevent contamination when reassemble, the knowledge and the technical spec's to do the job. The second choice which I would recommend is take it to a shop. If the pump is damaged it will loose power as the oil in the hydro get hot and becomes thinner, the hot oil can bypass through the damaged part more easily instead of the pump and provide the power to the wheels. You could call the local JD shop and see if they have some tips you can try for your particular unit. Make sure you have any model number they may need to help you when you call. |

Jeff,
Check the fluid but refrain from changing it, do not contaminate the system with any dirt, a thimble full of dirt will destroy the system. Mort than likely the popoff in the pump is too low, take it to the dealer it will be money well spent, they will measure the pump output and shim the popoff spring accordingly.
