    I just bought one and wanted to know what to expect from it. Any special setup you ran on it ? What is junk on it? What is good on it?


    Thanks

    So you bought a 72" TT, which engine does it have? You purchased as good a mower as there is on the market. This is not to say you can't have problems with anything man-made. There really is no "so called" weak points on a Scag, the ride could stand improving, but then again; so could a lot of others.

    As stated on another post, we had 3 of these back in the mid 90's. Only option we had were Velkies. A little heavy but nothing that a good operator couldn't handle. Otherwise they were excellent machines that were very productive. We sold ours after 5 years to get our groundmasters. I still wish we had kept at least 1 of them. Never had a problem with them. Good luck with yours.

    What motor is on them now? We had Kohler 25's.

    It has kohler 25hp its a replacement motor the muffler is on the front of the motor and is kind of in the way to get the belt cover off. Is just a little harder to get the cover off. I have 2 48" walkbehinds now and i cant wait to get this 72" out and see how quick i can do some of my propertys.

    Thanks guys

    I have no idea what type properties you cut, but a 72" deck will give a 25 hp Kohler more than it wants. I've seen a 72" deck give a 28 hp Cat diesel more than it cares to deal with. No heavy cutting, damp grass, not taking off more than a inch, no problems. Taking off more than an inch, heavy growth, wet grass and the 25 Kohler is not nearly enough engine for a 72" deck, not even close.

    Think of it this way.

    30 HP Kohler 60" deck = .5hp/inch of deck (still gives me fits and starts)

    25 HP Kohler 72" deck = .35hp/inch of deck (will give you a hell of a time)

    I know that formula is a bit arbitrary, so let me put it to you another way. I had a 60" with a 25 Kawasaki and it sucked so bad I went out and bought a 30HP Kohler command.

    Interesting formula's. I don't know why you had trouble with a 25hp on a 60" machine. All of our 62's run Kohler 20hp and we have never had a problem. High, wet, thick grass and they all have Velkies and we never have had a problem. We also never had a problem with the 25 Kohler on the 72's. You can't go as fast as a Z master but we never had any problem of bogging down or stalling in high wet grass. Maybe we just got lucky.

    You are saying there is no noticeable difference with a 25 hp Kohler on a 72" mower in 6" tall damp grass cutting it down to 3 1/2"?:confused:
