Yesterday I picked up a couple of ride on lawn mowers. Ones a single blade COX, and the other is a much larger twin blade Murray, both not working. I concentrated on the Murray. Carbie needed to be pulled apart and cleaned, lots of gunk blocking the jets and passages. Starter motor needed a bit of work, seized mostly. Spark was OK. After a couple of hours it was running. Motor seams OK, no smoke or weird noises, its a 14.5hp B&S. One tire needed a patch on the tube. Cutting deck will need some work, and the belt is missing so I'll have to cut some string to length and visit my local belt supplier. The final drive is a hydrostatic transmission, it does work but is slow to engage, and the brake isn't working. It has a oil reservoir with a big screw on cap, just like those you see for your car brakes. Its empty, and I dont know what sort of oil these transmissions need? It is brake/hydraulic fluid, automatic/power steering fluid, or just plain engine/gear oil? Anyone know? Unfortunately there is no model tag on the mower, fallen off long ago.

Hey Glenn Sounds like you've got some serious mowing ahead. As for the oil, I couldn't be certain but generally as a rule most types of hydraulic transmissions use automatic/power steer fluid for blood. See if you can drain a bit out and check the colour. If it's red-ish then its trans fluid. Doug May The Power Be With You |

Glen , Here is a link to peerless Tecumseh Manual for lots of models. Lots of models The Murray Uses Peerless Transaxles in most if not all models. Page 87 in the PDF is the beginning of the Transaxle section. Also see page 123 for helpful adjustment procedures, Your low speed may be caused due to a bent linkage rod. In some cases only a part # is given for the Oil, Cheers Good luck Time has proven that I am blind to the Obvious, some of the above may be True? |
