MUST READ!!! It will save you thousands!

First off all the guys that own these big heavy commercial machines. When you hire the hourly help and just tell them how to mow the way you want it done, its not good enough. You have to make sure and let them know to always keep an eye on the gas. First thing the guy does is get far away from the truck where the gas is and runs out. then he drives the truck on to the property and fills the mower with gas. then he doesn't want to walk all the way back to the mower so he drags it with the truck back to where he is supposed to park. He released the brake thinking that would allow it to roll to where he was going. That's not how hydraulics work. You have to release the hydraulics by turning the lock counter clockwise. If you have 2 separate pumps, you have to release both pumps not just one. I you have a DUP series where one pump runs both wheel motors, you have to release both sides. NOT DOING THIS WILL COST YOU THOUSANDS!! Because you will break a wheel motor shaft when dragging it without the hydros not being released. Then when you get back where the truck or other piece of equipment used to drag it needs to be, you fire it up and engage the hydros and send trash thru the whole hydraulic system. Then it wipes your pump or pumps. So right there you have just done over a $1000 dollars of damage to the machine. Then a lot of guys think well its just a bad wheel motor. So they buy a new wheel motor and install it. Without dissembling every part that had hydraulic fluid in it cleaning everything. Then they fire it up and send trash into the new wheel motor. Then they determine its a Hydro pump. Then they install it without proper cleaning and wipe out a new pump and they still have a broke machine. Then they get frustrated and bad mouth the machine and sell it for scrap or trade it in on a new one. These mowers are heavy and get stuck or run out of gas and get dragged all the time. Just trying to stop you from wasting money!!

Make this part of your training regimen. Our policy has always been if a big machine goes down you call me first. I'm my own mechanic. It keeps guys from running the battery down or causing any other damage like described. Fuel is topped off at start of day and checked halfway through. I eliminated all tank valves too so running dry is highly unlikely.

Thanks for the post. How important of a step is this for "short" tows? My mowers get stuck frequently (at least once a day during Spring and few times throughout the rest of the year)... so when I pull them forward just 3-5 feet to get them out of the mud, do I really need to do turn these valves on and off? Seems like it'll certain add some time but, if it's necessary, I'm ok with that.

If you have 2 people let one move levers forward as you pull. If not I wouldn't take a chance.

Guys im sure any shop would love to have your money but I have been seeing this too much lately. I make good money doing these repairs, but I would rather educate you guys that take your money.

Some mowers have easy to access dump valves others are a nightmare. It is really hard on the drivetrain to drag even a few feet on greasy turf. You wouldn't drag your truck in park, would you?
