48" Deck Adjustment(s)
 

Thanks to Sam 'n Lew, my "new" 1641 is runnin' great.

Two items, first the Cub was stored outdoors for over a year. Lots of carb cleaning. On my 2nd (or 3rd fuel filter), seems the tank is really gummed up.
Any ideas to clean the tank without removal? I've been adding ethanol cleaner or storage whatever, seems to be working and then burp, filter is in need or replacement.

The annoying item, number two, is the 48" deck. Runs great but the two rear wheels leave skid marks in the lawn. I can live with it but, why not a fix. I just reviewed the deck manual and adjusted the wheel pins, three down, front wheels, three up for the rear. Where do most forum members set their deck wheels?

I mow the rear yard, 1/2 acre of turf one day, 2nd half front half of the lawn, next day. I like to keep a nice signature cut lawn. Hey, I took an agronomy course at Penn State years ago! Got to exceed all the neighbors expectations.

PS. I hate dandelions! Lets go Weed-Be-Gone!

For your plugging filter problem, have you replaced your fuel line from tank to filter/pump? As for the tank itself, honestly your best bet is to remove it and clean it that way. Also replace or clean up your fuel shut offs. It's easy to remove the fenders and tank to clean it. 4 allen bolts holding the seat on, 4 more bolts holding the fenders to the foot rests and it's off. Takes maybe 10 minutes. Then the tank should just slide up and out. :beerchug:

As for your deck wheels, do you let yours ride on the ground or keep them a hair off the ground? I let the wheels skim the top of the grass, that way the weight of the deck isn't on them constantly leaving marks in the lawn from them. That's the only thing I could think of without pics.

So got any pics? :biggrin2:

Agree with pulling the tank and cleaning with hot water and something like Castrol Super Clean. Also clean the shutoffs and replace the fuel hoses all the way to the carburetor. Use SAE spec 30R7 hose at a minimum, 30R9 if you have the big bucks. R7 is ethanol resistant. Don't use R6.

I use the '48 and '54 inch mowers. Forget the wheels for a moment. I set the deck height where I want it to get the grass the way I want then let the wheels down to almost touching the ground. I let the mower carry the weight of the deck. Others prefer to let the deck ride on the wheels.

The front of the deck should be maybe a 1/4" or so lower than the rear of the deck in cutting position. I don't have any problem with the wheels dragging.

Thanks gentlemen. Now I have shop chores.

Honest Honey, I'll clean the garage as soon as I finish this project.

That's the beauty of this hobby, the project is never finished!! :beer2:

If it gets finished, it's time to buy another Cub.

Seven tractors in my barn, keeps the sons and grandsons busy.

Two, new to us, both 66'ers. A B-10 Allis Chalmers and a Pennsylvania Panzer.

Boy's will be boys.

If I lower the deck where I want it, thinking deck wheels just touching the grass, will the hydro lift lever always stop where I set it?
Set it turning clockwise, a permanent low setting that suits me?

Up for transport, down to the new stop for mowing?

The twirly bird on the differential cover establishes the lowest cutting hieght. So yes, adjust it clockwise for the lowest down stop you want to mow.

Thanks Mike! I'm going to give that a shot (mow) in the morning.

Appreciate the quick reply, I'm new to the 1641 but gettin' to enjoy the machine.

Grandsons love the hydro, a bit young for stop 'n shift. :beerchug:
