I know this has been talked about off and on before but I felt we should make a single dedicated thread about it. I searched but couldnt find a thread like this on this subject. Mods if you could start a poll that would be much appreciated. The main question here is which motor do you prefer and give us the main reasons why you choose one motor over the other. I will start off with my reasonings. I will be right up front here and say I do not like the Kawasaki motors. 1. Kaw's are extreamly tempramental and hard to start unless conditions are perfect. If its cold or damp they get real hard to start. Especially if you have a pull start Kaw. Kohlers on the other hand tend to start right up time and time again never needing any adjustments which I can not say the same for the Kaw's we have owned. We just got our Gravely Z34 out of the shop for being hard to start on chilly days. Now its going back in because under full load it acts like it is running out of fuel which it is not. It has the 15hp twin Kaw on it. 2. From our experiance with the many Kaw's and Kohlers we have owned over the last 15-20 years the Kohlers have almost doubled the life of the Kaw. Our average Kaw tends to kick a rod or loose to much power around the 1,500 hour mark. Our Kohlers go 3,000+ hours with little to no down time and no noticable decrease in power. Our Gravely Pro 50 had 3,200 or so hours on it when we sold it and to our knowledge it is still going 2 years later and god knows how many hours. To date we have not had a single Kohler let go and bite the dust. We tend to sell the mowers and get new ones before the Kohlers give up the ghost. We start looking to sell around the 3,000 hour mark so we can incorporate a new mower into our line up. To date every Kaw we have had has either blown up or lost to much compression and had to be replaced before we decided it was time to sell and get a new mower. This thread is just to get an idea what everybody likes. This thread is not intended to start a flame war so please keep it civil and on a professional level.
