    Is eXmark thinking about or going to consider deisel engines in the near future? I would love to see one on a HP! Not being very familiar with running a deisel powered unit, are there any drawbacks?

    Diesel engines like gas engines have advantages and disadvantages. These go in extremes from one end of the chart to the other due to the various designs of the different engines that may be available.

    Most people believe a diesel has more torque, gets better fuel economy and will last longer. Many of these same people will tell you a diesel will also run louder, smell bad and vibrate you fillings out if it's not packaged correctly. All of these are generally true but there are exceptions.

    The biggest advantage in my personal opinion is for the guy who has diesel fuel that he stores on sight. If you've got several other types of diesel equipment such as skid steer loaders you may have a fuel tank on sight. It'd be great to be able to fuel all of your stuff from one tank on your own site. Often you can buy diesel at a non-taxed off highway use rate. This can be a substantial savings. In most cases you must file for a tax rebate for gasoline fuel tax because it is not available tax free at the pump or for delivery. Just a bit more hassle to get the same benefit for the gas user.

    It really depends upon what engines your comparing however. In the case of the 31 hp gas and 27 hp diesel Daihatsu that we use on our Lazer Z XP they both have the same life expectancy, the gas burner winds a power contest hands down but the diesel does get better fuel economy. The diesel also costs a little more as well.

    If you compare either one of the Daihatsu engines to an air-cooled Kohler or Kawasaki then all of the stereotypes are true. The diesel does have more power, will last longer, gets great fuel economy (relative to the power it produces) and it will be a little more expensive but that's the trade off.

    It all comes down to preference. For every advantage of a diesel there is probably an equal disadvantage as well.

    To put a diesel engine on a machine often requires other changes to compensate for the additional vibrations and loads associated with the engine. That along with the relatively limited number of diesel engine options that are available might limit the feasibility of adding a diesel to the Lazer HP line up. It's really difficult to say but I'll send your suggestion to the engineering guys. They're the smart ones that can really determine if it's a feasible product to build.
