Hey everyone. I'm a residential homeowner and I cut about 4 acres of yard. A couple years ago, I bought what I thought would be a mower that would last for many years. I bought a used 2002 model Grasshopper 321d with 850 hours. This will be my third summer with the mower. So far, I've had lots of little problems. First year was electrical problems with the PTO switch and various shorts. Last year it was blown hydro lines that were dry rotted and then more PTO switch problems. This year, it is back to more PTO switch problems. I'm also getting a fuel leak around what I think is the fuel pump on the engine. After mowing, the pump will have weeped fuel all around itself and is covered in gooey dirt/diesel sludge. The engine still runs just fine,but I see this becoming a problem in the future.

The problem is that my Grasshopper dealer is very slow on service so I'm usually out of a mower for about 3 weeks each trip. So that puts me in a bind because I don't like to borrow equipment from friends and family to mow while mine is in the shop and I don't like paying to have it mowed either.

Now I love everything else about the machine. I love the diesel vs gas. Fuel consumption is noticeably less than a gas. The machine is very wide and very heavy and sticks to hillsides like glue. The rear tires are very wide and get great traction. I rarely spin out. When other neighbors are getting stuck, my machine just eases through without any problem. The controls are smooth and not jerky, even when mowing in full throttle. The cut is amazing and makes my yard full of weeds and junk grass look like a golf course.

I'm just trying to decide if at the end of this season if I should let my dealer keep my mower over the winter and have them go over the whole machine with a fine tooth comb and replace anything that is 50% worn or more before it breaks. Have them replace bushing, bearings, etc and then have then completely repaint and re-decal the entire machine. I'm estimating $1500 to $2500 for all of this work. If that's not an accurate estimate, please feel free to correct me.

So should I invest in my old machine in hopes of heading off future problems or should I save up my money and sell my old machine to buy a brand new machine for next summer? My current machine had 975 hours.

The problem is; you can't really inspect to a point where you replace everything that is going to fail. Some things you can see, such as the rotted hoses or belts, but many things you can not.

It sounds like you're not one to fix such things yourself, so that takes alot of the advantage away from running older equipment. You need someone who does electrical work to go over your wiring and make sure it is up to snuff. There's not that much wiring on such a machine, so you should be able to get that in shape. Clean the engine and determine where the fuel leak is and fix it. Inspect all rubber parts for rot and replace them. Look for leaks of any kind and fix them.

Beyond all that, you'll need a crystal ball to know what else might fail.

Hope this helps in some way and best of luck.

BTW, I'm not familiar with the 321D. Are you sure this is not a 721D?

I'm no mechanic. The fuel pump isn't so much as a leak but it's more of a weep. And it only happens when the mower is running. There is no sign of leaking fuel as the mower sits in the shop.

The mower definitely is a 321D mid mount. The 721 is a front mount.

Olympus,

Diesels, have very high fuel pressure. In the fuel lines and other places there are often hard copper or other material washers. You might check all the fuel lines by just giving them a snug with a wrench to make sure they're tight. If that doesn't work, find someone familiar with that particular engine and they can probably find and fix it quick and relatively in expensively.

I had looked at the mower shop sight where they have parts information and did not find a 321 D so that's why I was confused. I didn't mean to insult you or anything.

Hope this helps.
