    I am considering purchasing a 72" AOS series with the 35 hp Cat diesel and was wondering if I could get some feedback from anyone that has a Bad Boy diesel mower. I currently have two Lazer Z XS mowers with the 35 hp Briggs Big Block engine and a 60" Lazer Z so this will be my first purchase of anything other than Exmark.

    My main questions on the Cat diesel are how many gallons of fuel per hour roughly does it use(my 2 big blocks avg. about 1.8gph) and how long have these particular Cat diesels been run in mowers(reliability). My big blocks are real strong so how would the 35 hp Cat compare to them. I was assuming being diesel that it would have more torque but would there much of a noticable difference in power overall. My last question is what would should I expect pricewise for a 72" cut with the 35 hp Cat diesel engine. Any other feedback I could get on Bad Boy Diesel mowers would be greatly appreciated.

    the AOS 35/72 sells for $12,700. It puts out 70lb-ft of torque, roughly 20 lb-ft more than your big block Vanguards. On the charts, the big blocks are rated at 3gph, whereas the CAT uses 2gph. What that amounts to in real world numbers, I couldn't tell you. Obviously, your big blocks are using far less than 3gph, but if these numbers are anywhere close to accurate, the CAT is 30% more efficient.

    You're gonna love the speed, power, and comfort of the AOS (as well as a great cut quality).

    tb8100, Thanks for the info! Does anyone know how the 35/72 has been are far as reliability and durability. I do a lot of large area mowing that is not smooth so the mowers get bumped and banged around a good bit. The Exmarks I own have held up pretty good. I have seen Bad Boy's features they advertise like the 1/4" thick deck and strong frame, etc.. Are they as durable as other main ZTR brands.

    With regards to reliability have there been any issues with the Cat diesel so far? Is it a Cat diesel made by Cat(I have a Cat backhoe with a Perkins engine). I have heard that lawn equipment dealers can't work on the engine. Could I go to my local Cat equipment dealer to get work done on it if needed? The last question I have is why are Bad Boys priced lower than brands like Hustler and Exmark? I've heard good things about Bad Boys and am in no way trying to run them down but a 35 hp Cat diesel in a Hustler or Exmark mower if it was offered would probably run 14,000 plus. So why are they less expensive?

    I think I would look at the kubota pro ZD331 (31hp)with 72 inch cut for about the same price.:)

    I am a dealer for these mowers and have had only positive experiences. I rarely do a warranty service on anything bigger than ZTs. The frame is very strong and very durable. You'll find the suspension will reduce the strain on the chassis as a whole over the lifetime of the unit.

    The engine is a Perkins C1.6, a 1.5L 4 cylinder engine that wasn't designed with the turf application in mind, it just works well in it. The C1.1 is another Perkins engine Bad Boy uses (the 28hp), and you'll find it on the Scag Turf Tiger and a couple other well known machines. Both engines were released this time 2 years ago. I don't know of any real issues with them. Perhaps someone running these could provide some input on the reliability. As far as service goes, your local Bad Boy dealer can do external work, but all internal work needs to be done at a CAT service center. Alot of times, CAT will send a service truck right to your dealer so you don't have to take it to another service center. Talk to your dealer to see how they have worked this out.

    There are a number of reasons why Bad Boys are priced better than the competition, and it isn't that they're made in China or something ridiculous like that. The folks at Bad Boy are just super at running as efficiently as possible. They build units to order, so there are no mowers sitting around waiting for dealers to buy them. Everything cranked out of that factory has been sold. They use robotic welders and laser cutters to reduce the manpower required to build machines. They also have a state of the art powder coating system capable of cranking out 2000 units per day, though it only takes 15 employees to run it. Another thing is they go direct to dealer, so there is no distributor making a few percent per unit. No middle man, so to speak.

    There are a number of other things that make them cheaper and it doesn't pertain to lower quality construction. Does that answer your question?

    that 31hp has nothing on the CAT as far as power output, and the Bad Boy is alot faster and a whole lot more comfortable of a mower. Can you even get the Michigan suspension seat on the 331?

    tb8100, Thanks again for really good information on the Bad Boy mower. Being that I currently have 2 Lazer Z XS mowers that will run 12 mph the Kubota wouldn't interest me if it is slower. It looks like a nice machine but not for my application. Doing mostly large area mowing I need something fast(15 mph range) and powerful. That mainly is why I am looking at the Bad Boy AOS series. Its the only ZTR other than the Hustler Super Z with that kind of top speed and it is more powerful than anything currently offered by Hustler.

    The only down fall IMHO would be how long would it take to get a CAT service truck to my dealer to service the cat motor?
