Bentley Meredith,
Do it yourself if you can, this thread has a few good pointers on changing all the fluids, including the hydraulic system filter which is very tricky as the fluid will continue to pour out until the new filter is screwed on. I only lost about 3-4 quarts in about 20 seconds! Why there is no type of valve in there is beyond me. I changed my engine oil at about 52 hours in my R4041 and it was really dirty. Oil and filters are cheap, engines are not. The engine oil now has about 60 more hours and looks much cleaner than the original oil that came out after 52 hours. I got my filters at Carquest, and also got some backups from my dealer who UPS'd them to me even though he's only 45 miles away. Engine oil was easy, my 4 cyl. Mitsu engine has a double sump b/c the driveshaft for the front axle runs right thru the middle of the pan! Didn't expect that, so I had to drain both sides of the oil pan, imagine instead of a square pan under the engine, a "W" shaped one. I drained the oil at dusk and was going to come back to finish in the morning and wondered why only a couple of quarts came out (1.9 gal. capacity for the engine), really threw me until I could see better in the morning. Maybe there is a local tractor mechanic who will agree to do periodic maintenance for you at your place, saving any transport costs for simple stuff like oil changes. Good luck, send some pics and keep us informed.
