|Bruce||I have a 1994 Yardman 46" deck garden tractor with Hydro Gear transmission 718-0241 below that is another number 4061C1109. I found out it uses 20-50 weight motor oil but I do not know how much to put in. Does anyone know how much oil this transmission uses with a filter change? Thanks.
|bontai Joe||I'm fairly sure that there has to be a "check" plug in the housing somewhere, where if the fluid reaches that level, it is full. Then you replace that plug.
|steve||thanks for your reply to my problem, but I was having trouble with the mower not pulling so I tried to find a fillter and i let the oil out at a place where I thought the fillter was. I was WRONG.Now i need to get the oil back in but I see nowhere to put the oil back in.HELP!!!
|Pat||I have a 1996 Yardman with a hydro gear transmission also. It uses an HG 50037 filter (or 51563). Does anybody know of an equivalent filter I can buy at some local parts store. I can order one on-line for $11.95 with $8.95 (and 5 days) shipping. I was hoping to find one faster.
|Brewster||I just asked MTD the question about how to change the hydraulic oil and below is their response.
HYDROGEAR TRANSMISSION SERVICE (Pre-1998)
These Hydrogear® transmission units require an oil and filter change every 200 hours of use.
Units with an external (screw on type) hydraulic filter, part number HG-50037, are easier to work on. Simply disconnect the lowest hydraulic line from the transmission and drain it there. To refill, disconnect the uppermost line from the transmission case and fill it there. IMPORTANT Leave approximately ˝” air gap for fluid expansion.
Units with an internal filter , part number HG-44964 , require removal of the transmission and separation of the transmission case halves to access the internal filter.
Removal of the rear fender may be necessary in either case to ease access to the lines.
Refill with SAE 10W40 motor oil OR (in colder climates) SYNTHETIC SAE 15W50 is also acceptable.
These are self-purging hydraulic systems, therefore bleeding is not necessary. Although you should check the fluid level after 5 hours of use , after an oil , change to assure proper fill level after purging.
To order parts and accessories or to check on current pricing and availability, please call 800-800-7310. This will automatically connect you to the parts distributor nearest you. *Note that prices vary across the country due to various shipping and other related costs.
