7/27/2015 I don't have a traditional riding mower. I have a tried and true, 30 year old, 2 wheel Gravely walk behind tractor, with mower deck and a riding sulky attached. The sulky is about 15 years old, and the seat has a couple of cracks in the black vinyl, exposing the foam. I needed a cover or a new seat. I wasn't sure this would fit, but it does - beautifully! This is better than a new seat, because of the "perks". Based on the measurements, I ordered the Medium sized cover. It was a snap to put on. Took about 10 seconds! An elastic hem encircles the seat is for a good fit, and is substantial. Imagine that it will weaken in time, but that's what bungee cords are for! Used the seat cover it for 1.5 hours of mowing so far. Perk #1: Cover does not get hot. The tractor was sitting in the hot sun when I went outside to mow. Temp was over 85. Seat cover was NOT hot. Appreciated that since I was wearing shorts. Note that the seat cover in the ad looks black. Mine is black too, but the seat and backrest portion are silvery-gray, helping to keep it from getting scalding hot. PERK #2: And I used to slide a bit on the old vinyl seat - my yard has a few hilly turns. This didn't happen with the cover in place. It moved a tiny bit, but not enough to be a problem or annoying. Has some cushioning and a texture that makes sliding less likely. PERK #3: I LOVE the pockets on the back. I stuffed a hand pruner and a 30 gallon trash bag into the pockets. My rural 2 acre yard is bordered by a stone fence grown over with trees, brambles and vines. A lot of unwanted vegetation tries to creep into my yard. As I was mowing, I encountered a few small low twigs and brambles protruding where they shouldn't be. Hopped off the mower, grabbed the pruners and made quick work of them. At one point, I just paused the mower, grabbed the pruners without getting off the tractor and got rid of the offending twigs. I used to carry the pruners behind me on the seat, not so comfortable as the pouch! When I was finished mowing (I am temporarily storing my mower outdoors this summer) I parked it, grabbed the trash bag from the handy rear pocket, and used it to cover the seat, pulling the drawstrings to secure it against rain. The manufacturer claims the seat cover is weather resistant, but I figured dry is better. (I cover the rest of the tractor with a plastic tarp.) Love those pockets. I'm sure I will find other things to stuff in there as time goes on. (Water bottle? Ear protection? Spare tractor key?) It does come with a one year warranty which can be registered on line or through the US mail with the enclosed paperwork. (Save your receipt - its required to register.) It appears to be well made and sturdy. Certainly not flimsy. Of course, only time will tell. **** The instructions that come with it do caution: Do NOT use this product within the first four weeks of ownership, since compounds in a new mower can release gases that will cause dyes in the cover to transfer to the mower/seat and stain. That said, it did not have any "funny" smell that I noticed, if that is a concern.
