I have had a Dixie Chopper 72" cut with 32 HP Gas Generac Engine for just over 3 years. Only has 250 hours on it. I own a 100 acre farm with lots of grass to cut. I was using the mower last week to trim some pasture after the cows had eaten it down and I blew the engine. I had the mower for 3 years and 3 months and you guessed it-generac warrants them for 3 years. We are trying to see if dixie chopper/generac will stand behind the engine given the low hours of the machine. I was very faithful about maintenance (changing oil and filter regularly) and I had checked oil level before I took the machine out the day the engine blew. Well, I am wondering if the pasture was to much for the gasoline machine. It seemed to bog down the machine somewhat. I am considering buying the 35 HP Diesel Dixie Chopper 72" machine. I also have a Kubota compact excavator and I have been real impressed with the quality of the that machine. For that reason, I am considering the 31 HP Kubota zd331 Diesel 72" mower. Another plus is the Kubota is probably $3000 less money than the dixie chopper. The Kubota is a 31 HP Kubota diesel and the Dixie Chopper has a 35 HP Yanmar diesel. Because I felt the pasture was causing the 32 HP Gas Generac to bog down, I wonder if I will see a noticeable improvement in the Kubota in spite of it being less HP (31 HP). I have heard there is noticeable improvement in torque when moving to a diesel from a gasoline. Anybody else had any experience with a generac engine blowing with such low hours?
