What oil should i use in my wheelhorse rearend? it is not hydrostitic.

Go to Toro/wheelhorse .com then select parts.

low oil that modle has a oil kill switch to prevent damage if you run out of oil so change oil refill to safe and try that if dosnt work we can try something else charlie let me no what happen

If it did not have oil it would make the noise going straight. Check your brakes and the wheel bearings for play. Oil should be a GL5 70-90 wt gear oil.

The rear end will be to hot to touch after driving but if it is really hot (like cannot get the finger anywhere near it )then the problem will be in the diff . Possible pin ion bearings are under excessive preload by nut using a new spacer under the pinion flange or attempting to remove back lash at the pinion flange by tightening up the pinion nut. Excessive oil and the wrong grade of oil ( ordinary diff oil in a LSD diff) or running one side tyre at a different profile height to the other. The popping noise may be oil burning off ( like fat in an overheated fry pan)

I am assuming you have a manual PTO clutch since you did not mention a PTO switch. The starting circuit generally is a series of switches wired in line (series) with each other. You have bypassed the seat but there is usually a switch for neutral, PTO, oil level, and clutch. You will need to trace the wires from one to the other to find the problem. If the seat has a double switch (3 or 4 wires) it is wired through the PTO switch which may be a double switch to short out the ignition so that part of the circuit should stay open to operate. If the oil level is ok and the oil has been changed as recommended you may better consult a Wheelhorse service person. Bypassing the switches is for testing only! I DO NOT RECOMEND LEAVING ANY SAFETY SWITCH BYPASSED. Any defective or out of adjustment switch should be replaced or corrected.

should hold 6.5 pts oil, 8 oz of friction modifier. I would use a 90W HP synthetic oil.

Direct from the Toro/Lawn Boy data sheet is this information for the hydraulic oil. They state to use
AW Hydraulic Oil, biodegradeable, Mobil EAL224H. Here is a copy of the data sheet.

im not that familiar with hummers but it sounds like youve found the end of the transmission vent hose or possibly the front differential vent hose and they will have seepage of oil sometimes. however if its a constant oil drippage, then there could be a buildup of pressure inside tranny or rearend. if u follow the hose down to its beginning youll know if its the trans. or differential(rearend). it might be normal to see this fluid,or it could be too much fluid inside trany/rear.

Your Onan engine will do excellent with Mobil One 0w40, Mobile One 5w30.

DO NOT use hydraulic oil in the transmission/transaxle, you will destroy it. Your tractor uses an Eaton 11 Hydrostatic transmission pump with the oil resevour being the cast iron transaxle. The WheelHorse transaxle is as rugged as they come. It uses a solid cast iron housing, case hardened intermediate gears and forged differential gears with an eight pinion differential.

Your transaxle requires 10w40 synthetic or conventional oil as well as a wix 51410 filter or the OEM wheelHorse filter. It should be changed every 100 hours with conventional oil or 250 hours with synthetic. DO NOT use hydraulic oil!
