Ditto on the hydro. Your dealer should steer you towards turfs (they're called that for a reason). Renting a splitter, if you really can accomplish all your splitting in a couple days makes sense. Explain to your wife that a tractor, if purchased right, is simply an investment that will be very helpful while you own it, then can be resold with almost no loss. I will say again, buying used is not a risk if you approach it with caution and common sense, and makes my statement above more likely to be true. I have actually made a bit of money when selling a used tractor that I had cleaned up and added some good lighting to- the one that proved too heavy, with R-4s, for lawn operation. If you buy a gas splitter, simply run it dry before storage. I have a 10 year old gas generator, gets used 1-2 times a year at most, but I run it dry after every use. It still starts with the first pull. Stored in the shop, under cover. No problem.
