Customer Question

I have an older New Holland tractor that is a LS 35. I am now having issues with it loosing power. It is moving very slow in reverse and even forward. While I am plowing snow, after about 20 minutes, it gets worse. I have a similar John Deere mower and never had the same issue. Normally if the transmission was not operating, it usually was a belt or keyway issue on the wheel hub. Not really sure how to diagnois the repair.

What is the long model number? IS this hydrostat transmission or the geared transmission? You have replaced the transmission drive belt and it is tight?

Customer: replied 1 year ago.
hydrostat transmission, I don't have the full transmission number with me. The belt is tight.

OK, I only see one LS35 with 15 hp engine. Shows a reservoir for hydraulic fill. Is transmission oil level up?

Was transmission low on fluid? Please accept and rate to close.

Customer: replied 1 year ago.
It was not low on fluid. It happens when it warms up and fluid ends up in the reservoir. I just did not know if it was such an old trans that maybe it could use some friction additive or not or maybe it needs to be rebuilt

If fluid level is correct, and gets worse as it warms, transmission is likley worn and needs repair.
