I've been on the lawnsite for a while now. Well to start off with a lady ran a stop light and I hit her with my f-250 on monday evening. Totalled her car, bent my bumper. Anyway I was mowing on Tuesday and my J.D. F-620 started to smoke a little. I was like what next? Not my week. So on Wednesday I was like I can't have my equipment breaking down. One of the guys that works for me wanted my 48" lesco walkbehind- he cuts some residentials on the weekends. I was debating because that Lesco is what got me started and is still running strong, but I agreed to sell it anyway. So I called my local Exmark dealer and he cut me a real good deal on a Lazer Z 60" and a 52" gear walkbehind with ecs, really did not want the ecs but could not refuse the price. Prices was so good I decided to get a 8.5' by 24' enclosed trailer (that I have really been wanting) to keep the new equipment looking as good as possible. Didn't demo any thing- just taking Lawngodfathers' and many other advice. I hope I am pleased. The best thing about it is that I had mistakingly added some wrong weight oil to my J.D. and when I changed the oil in it this weekend it did not smoke any more. So now we will be running a J.D. 60" cut Z-TRAK, an Exmark Lazer 60" cut, and a Exmark 52" gear drive, all tucked away in a enclosed trailer. Can't wait to get my PSD back to pull it all, its going to be hard on my 350 in the dump truck. Anyway I'll keep you posted on what the best mower is.
