ok I have a 52 exmark hp 20hp my first commercial mowing machine. I did do my homework before buying plus I had a friend that recommended this brand after years of cemetary mowing and all models to choose from without any out of pocket expense to him so I had to go with what he recommended. I have been very pleased with it's performance with a few exceptions. I purchased it from a place that did not even know customer satisifaction so I switched dealers for my second year of warranty. My first year I did not run the micromulch and this year I have. It is amazing the finished product which has amazed all my customers. However I have had to in the spring mow 1/2 the deck capacity one because of quality went from good to exceptional and I demand exceptional. I also had to slow down a bit it did bog down the motor. My seat just broke and was welded for a fix which I am not sure I agree with I have the cheap model seat without springs (if you are buying I recommend only the best seat. my light bulbs only last about 5 days I think because I mow so much with the rops down and the vibration still poor design. I have started removing the bulbs when not needed for night mowing and put in the glove box of vehicle. I am asking those of you who went to the 60 with larger motor if it is enough. I really like the 52" due to entrance size of some back yards. I also am doing some cemetarys this year ya I said I would never do that lol I had to take some on to pay off equipment so I can keep one under warranty at all times. I also live where service is very hard to be happy with. What I really want is a 52" hp with a 29 horse dfi with the better seat etc. since the mule design takes 13-15 % of the horsepower to drive the machine. After reading some posts I am now very concerned with the "new" equipment. I have already been told the 27 kohler is enough engine and it probably is but after this year with gas prices I really want a dfi. I drain my two 10 gal tanks befor the day is over and it is a real pain to refuel one hour before finishing sometines causing me to drive 15 miles for fuel. I also would definitly test a triton deck before I buy again but my problem is I know on the second purchase what I need and want but of course they do not offer that and they tell me no one needs that well I can tell the company has a few people with power that also have very big ego's. I also have a skagg dealer close but never heard of hustler. I am requesting any of you with a 60"29hp or 35hp that upgraded to please tell me what is wron with the model if anything.
