washing under lawn mower deck

Anyone on here ever try making a sprayer system to drive their riding mower over to wash the under side of the deck?

My Craftsman 24 HP unit has a quick connect fitting for the hose. Hook it up and engage the blades for about 3 minutes - does a really good job.
 
Someone here made one out of pvc. Screw the garden hose to it and turn
it on. Was kind of a near idea. Dont remember what size hole they
drilled. Was probably a year or so ago. Think it had a handle so you
could move it around under the deck.
 
The very best thing you can do and gets the best results like magic.
Do you have a stream near buy? If it has a gentle shallow bank just
gently drive your mower in till the water touches the bottom lip of
the deck. Start the mower and rev up your engine to mow speed. Raise
or lower the deck a little and the next thing you know the blades have
formed a couple of water tornadoes under that deck. You will not
beleave how much crap comes out. Also can do it if you get big puddles
in your lane or on the side of the street. You need enough water so it
really makes the mower work. It will go SHUNK CASHUNK CASHUNK!! It is
awsum! !!!
 
I welded a pipe fitting on a Wheel Horse deck and fitted it for a garden hose. It worked good if I used it immediately after mowing while the stuck grass was fresh. It wouldn't blast it loose if the grass dried out.
 
It sounds really impressive too. Sounds like a cross between some kind of demented Army vehicle and a V8 powered cement mixer. As I said you can't believe how much stuff blows out. Leaves it almost totally spotless. Love it !
 
Hello Dusty MI,

You can buy a clean out. Mine came from a pressure washer water inlet fitting,

There is one more thing to keep in mind. If your mower spindles are protected from water, then you can use a deck wash system. However, there are spindles out there with unprotected bearings, and any such wash will help wash away the grease.

I had an older Deutz mower that was this way. It had grease zerks under the deck. Didn't even know that when I bought the thing used. Neither did the guy I bought it from, who ended up buying a new spindle for me as one was bad from him not greasing it.
 
Yes, immediately after cutting the BEST time. My old one I got lazy and didn't clean it after a couple of cuttings. Took about an hour with a screwdriver and small spatula to get it clean. The system on the new one is 'almost' perfect. Before I put it away for the winter, I go under and do the screwdriver thing - take just a few minutes.
 
I'v described on here before how I made a small crane out of a couple of four by fours, pulleys,
and a boat trailer winch. I can stand my rider on its tail and have at it. I usually mow when the
grass is wet anyway. No dust and grass clippings in my face and ears. Makes greasing the spindles
and changing blades much easier. Twenty years old mower and no rust at all. TDF
 
Think it was Glenster that had about three sprayer nozzles on a pipe buried in the ground, drive on top and pull the hydrant lever.
 
I'm still using a 1969 Wheel Horse 48 inch deck, on it's third tractor now, installed the newer style mounting brackets about 25 years ago. It gets hosed out after it's 4 hour work out a week.

yup, i modified the origional and bolted the sprayers to an old sheet of barn tin big enough for the mower to sit on . a lot less mud!!!!
 

I have never had a problem with a dirty deck I don't mow wet grass either... Neighbor does tho he mow's in the rain, last week I raised his mower on the lift it was 2" thick in caked grass he scraped it off the next time I seen him mow it had just rained :shock: He is gonna mow his grass 1 to 2 times a week come ell are high water... He's from El Salvador I don't think I have ever seen a guy that loves to mow grass more than he does...
 
That's a nice looking Wheel Horse, and you've taken good care of that deck. We should all be looking to you for advice on deck care. My deck is a rear discharge from about the same era, but it's not had the good care that yours has had.
 
If you have grease able spindles it is fine to wash out with water but if you have sealed bearings on spindles your asking for trouble. I
had one of my Garden tractor mower with sealed bearings and washed it out with water and every 2 years I was replacing bearings . If a
sealed bearing seal gets a hole or seal goes bad water gets in and they rust.
 
Why on Earth would anyone want to get water on a mower deck? Water on steel equals RUST. I've got 40
year old mower decks that are still sound, solid, may have some surface rust but not falling apart like a
deck that gets washed.
There's many places you can't see that water can get to where theres no paint, will rust on contact
with water.
Take a walk around your yard before you mow, toes of your boots/shoes get wet wait another hour to
mow. Dry grass clippings don't stick to themselves or the mower, wet ones do. Dry clippings polish the
underside of your deck.

You live in an area the grass is always wet, get some sheep or goats!
 
I read all the answers and have been through them, tried them all and more not listed.

I bought the gadget (about $35) that goes on a pressure washer that swivels 360 so you can pressure wash underneath while
standing/kneeling adjacent to the deck.. Works ok sometimes but since you can't see what you are doing, it's iffy.

Bought the deck washout doodads and installed them, 3 in a 52" deck,made a manifold with 3 snap on heads to fit the water hose and
supply water to the 3 fittings,, no big deal....waste of time.

Built a spray manifold out of PVC with 3 vertical heads, capped off with several holes drilled in each for a spray pattern. Drive the mower
over a ditch, insert under mower. turn on the water full blast and run the deck at max rpm for awhile. That worked ok.

Spring is a !@#$%^& even when you wait till 2pm. to try to get dry grass, especially Rye and it's wet stems....and Rye reseeds itself
annually, so Rye is what you cut in the spring till it gets hot..

Have removed the deck on the 52" DR mower, cleaned, repainted with quality enamel, applied deck spray.......works ok.

Made a couple of ramps out of 6x8x16 concrete blocks and steel purlins for ramps......works pretty good if you don't mind wallowing
around in the mud. Took my creeper out on several occasions to have something to lie down on while spraying.

Bought a screw type front tire mountable front end lift for access underneath. Works ok to scrape out the stuck stuff.

Bought an engine lift.....like you use to remove an engine from a car.....parked it in the yard...lift the front end......works ok, but have to
move it constantly due to mess made in the yard builds up.

Yesterday I was under the 61" Ferris I bought last year. I thought the deck was clean but in mowing it left a lot of stems standing. Parked
it in the shop, got out the Branson 2400 with FEL, pulled up to it, hooked a chain and raised it up. The bottom was solid cake. I removed
about 6 scoops (you know the kind of scoops you use when feeding oats and such) of crud out from under the thing.

When finished I went in the house and emailed the dealer for a trade in on a front mount Grasshopper. Waiting for his reply. Never had a
front mount and don't know how it will do on my varied terrain. Waiting for his answer and thinking about whether or not this is the right
decision.

I have a half a dozen or so mowing devices. Started with a tractor mounted shredder and wound up in the riding mower arena......cleaner
cuts, faster even though the mower was larger in diameter, no soil compaction, mower for every terrain, and safer....no roll overs.

The best cutter I have is a little Husqvarna 46" twin blade midmount with a stamped deck. I put snow studs front and rear (front for
steering traction on pond banks and rear for drive traction). Being 2 blades helps sweep clippings out. Being a tall, stamped deck, it has
no sharp corners to collect things. I took the Kohler Command single off it and installed a BS V twin; plenty of power. Worked the seat
over good to get a soft ride. 2 problems are the fact that it's only 46 when I have several acres to cut at a time, ride is ok but not all that
smooth with my modifications, and no sun shade. The Ferris solves all those problems but like other mm mowers, is a !@#$% to keep the
deck clean.
 
When the underside of the mower is clean, paint it all with graphite paint. The graphite reduces the amount of grass that sticks to the mower and what does stick is much easier to scrap or wash off. The paint on vertical surfaces may need to be repainted from time to time, but paint on the horizontal surfaces lasts for years.
 
Hobo, don't feel like the lone ranger. My neighbor mow's at LEAST twice a week.
I don't know how he can even tell where he's been. I don't try to keep up. I
always considered once a week enough. (Unless it rains a lot) Then maybe at 5 or
6 days at the most !
 
I did on my DR 52" last year when I decided to clean up the inside of the deck. I primed with quality primer and enamel then used the green can of moly paint/coating you use on farm equipment sliding functions, like sickle bars and square baler pistons and such. So far so good but will have to admit I haven't used it all that much and surely not on wet grass so we'll see.
 
My JD deck has a quick couple port and of course, I have lost the quick couple hose connector. Unhandy as all git-out. To do any good, has to be washed EVERY time right after mowing, even iffen yer tired and it is turning night time. lol Then you have to run the tractor full throttle with a 40 lb cement block in the seat
as the mower won't run in "park" and if you don't have the wit to sit in the seat all the time it takes to clean a 54" three blade deck....well you get my drift. So once in awhile, prop up the front end and lay on the floor using a putty knife and abundant evil thoughts, scrape the caked crud off. It really does well keeping me out of the local bar. Leo
 
Yes. I have a zt Hustler that has the old style deck and it is really crappy as far as plugging up with grass (only complaint I have about it). I took a 2 foot 1/2 inch water pipe nipple, capped one end, drilled 1/8 inch holes every few inches, attached a hose fitting on the other end and welded 2 poll barn spikes on it. Hook up the hose, step into the ground, drive over it so it's under the far side blade, turn on water and start the deck.... that was several years ago, don't even know where the thing is now.
Went to Harbor Freight and bought a lawn mower lift. Pull the mower into the garage front wheels on the lift, jack it up and lay on an old sleeping bag with a putty knife. Do this after every couple of mowings, sucks but it is the only thing I found that works.Good luck.
