First off let me say that i have many commercial customers that are good, but MOST OF THEM are horrible. They don't believe in grease guns, oil changes and cleaned the built up grass off the machine. They DO BELEIVE in complaining when the machine is broken. I had a crew drop off a Navigator they bought last season. Just under 500 hours on it. I didn't write up the work order but I walked out side and was like WTF??? I have to take pictures. The thing is covered, COVERED in dust and grass. All that was wrong is they got the discharge chute from the deck caught on a pieces of the tailgate and luckily snapped on of the screws off that holds it on. So looking at the condition of the machine, for shits and giggles i pull the dipstick to check the oil. Oil? What oil!!!! Almost empty and like black paint!!!! So i pull the air filter.....HOLY ****!!!! Packed with dust!!! How can you spend 10k+ on a machine like this and let your guys destroy it. The front caster wheel bearings are dry as a bone. I called the owner and left him a message to drop by the shop monday morning so i can make him aware of the situation. If he brings the thing in with a blown motor or something, I won't even lift my finger to call Kohler about warranty repair if it comes in looking like this again. What do you guys do? I would make each crew be responsible for servicing/cleaning the equipment. No reason not to spend an hour a week greasing, cleaning, changing the oil, and sharpening the blades. I just can't believe it. 10 minutes later, a guy drops off a Walker and a Scag walk behind. Same thing!!!! He said the blower wasn't turning on the Walker. I looked real quick and couldn't even see the blower, never mind the belt there was so much grass. The Scag looked like it was used as a mudflap on a monster truck!! Oh by the way guys, don't bring your machines in for repair with the bags full of grass. Dealers do not appreciate that. I dump it in a trash bag and put it on the deck for them to take with it when they pick it up.
