I may well do that, at least with one side but I'm confident in my measurements and my terrain stays the same from week to week so the test was on the grass I cut. The factory blades perhaps make a difference but I've ran a tank completely empty a couple times and it was empty considerable faster than I expected it to be. I'm as certain as can be that my measurements are accurate, as bad as they are. It is kinda hard to believe but, again, I took pains and my numbers are correct. I'll tell my whole zero turn story whether anyone wants to hear it or not. Back in 1999 I had a Garden Way Troy Built lawn tractor with a 38" mulching deck. I hauled it in the bed of my 1988 350tbi GMC pick-up, loading it with those aluminum ramp ends that I had on a couple 2"x12"s. I had the holes drilled in the tailgate where I'd put a couple screws in the ramp to keep it from sliding off the tailgate. One day the screws were misplaced so I loaded it anyway. No problem. I got complacent. One day I was loading without the safety screws and forgot to raise the deck. It spun the ramps out and I dropped the mower on the concrete driveway. I missed a real good chance to get hurt that day. I took the mower to New Albany Tractor to be fixed. Ran up about a $600 bill but it was fixed right. While I was there, Honest John Read touted me on a Dixie Chopper 20th anniversary edition that was priced at $4995 same as the price when DC were introduced in 1980 is what he said. Well I loved it so I bought one. Kept it 10 years and put about 500 near trouble free hours on it. It burned about a gallon an hour. It only had a 3 gal tank and a 17hp Kohler Command 50" deck. I could finish cutting without running out of gas if I started full every time. I got tired of that and the rough ride and the chain ht adjustment but the mower handled the best and cut very good. Seems like I got $3000 or 3200 in a private sale. When Grasshopper came out with their 226V I thought that was the answer. 12 gal tank, 26 hp Briggs, springs under the seat....everything I wanted to improve on my DC so I bought one when the factory rep was demoing at my local GH dealer. My buddy Sam ran a gas station 4blocks from where I live and I could get there driving the alleys so I was going to end hauling gas in 5 gal cans and life was going to be great. I filled up once and about 3 days later one of his gas tanks sprang a leak and Sammy closed out his gas tanks and quit selling gas altogether. My GH was one of the first ones off the line and it was a lemon. Chewed completely through 4 belts and threw the belt every other time I mowed seems like. The Briggs developed a serious oil leak at 150 hours and I just didn't trust the mower so I decided for my 62nd birthday I'd treat myself to a high end mower and now here I am whining about how much gas I'm burning thru my BobCat Predator Pro (but that's all I can complain about as I really like everything else about this mower.) If I could turn back the hands of time and get a do over I'd still be buzzing around on that old Dixie Chopper.
