(y) Quite often it is something very simple. You proved that.

Au contraire. Bearing grease only seals electrodes from oxygen. It is not a conductor of electricity. Vaseline both seals and is a promoter of good conductivity. I've used it with zero problems that way since 1961. So were I to change, I'd use a dielectic like Noalox, or something similar.

So bearing bore and fit keep the PTO shart in place? Good to know. Thank you. For easier time of it, should you ever have to do another one, place PTO shaft in freezer, lay bearings out in sunshine. Make some coffee or have a cold one. Time you are finished, all is ready to be easily...

Good to know. Petroleum jelly is a good conductor of electricity. It also seals electrodes and terminals from the effects of oxygen, and that is how it fights electrical corrosion. No problems from using it for past 60 years, even on battery terminals in our powerboats over the years. I have...

Always used it since learning about how well it protects battery terminals and electrodes in High School Basic Auto Shop. Thanks for tip. Never had a problem from using it, but don't want one either!

For my money, Kubota diesel best small diesel you can buy. They are rugged, reliable units. I only use OEM parts on mine. And in fact most anything that attaches to a kubota engine will have it's own Kubota part number. I did buy an aftermarker alternator for mine tho. May not last as long...

PTO sheave attached to crank via square key. If key not sheared, no such proelem. My 930 D Hopper has removable stub shaft that bolts to back of flywheel. 4 bolts thru flange that attacnes to center of flywheel. If your mower has that, then you are either being scammed, or mechanic ignorant...

Was going to suggest looking at both lever safety switches. I had similar start die issues with my 930D2. Buy a hand held infrared temp gun like the HVAC guys and pro mechanics have. I found one in eBay for around $8, and have it in glovebox of my Hopper just in case. I have to wonder if...

They are supposed to be self-bleeding. I had similar issue with my 2011 930D2 mower. Looked at belt tension and weak side was loose. Turned out someone replaced belts to both, but over-tightened sheave pivot bolt on L side. That caused that belt to gradually become looser as it aged and...

If you look on eBay, be sure to use Grasshopper name and Grasshopper part #. Most vendors of NOS stuff use those to help bring customers to their post. Has worked well for me a few times.

Not familiar with your model. I once had weak discharge on my 930D2 Hoopper. It tured out to be bad 'E' relay. That relay (one of 5) goes from PTO switch to PTO clutch. It was either dirty contacts or weak conttact pressure. In fact it finally beban go kill engine when operated that same...

Governor issue, linkage, spring, etc. Or maybe carburetor accelerator pump partly clogged. Acetylene tip cleaning file sometimes can be used to ream out that passage. Other times may need overnight soak in carb cleaner.

I like the idea of rear discharge. Suspect golf course mowers use decks like that to eliminate visible clippings. But I suspect that more crap can get scucked up to clog radiator fins with rear discharge. I know that I am going to add a home made dust catcher beneath me seat to catch some of...

Have you tried running it briefly without air filter in place? Part of fuel is air, after all. I've seen this exact thing once before. But it was accompanied by a sooty looking exhaust the time I saw it. Had smilar issue with a small gasoline powered edger, and was dirty air filter. No...

My condolences for ailments your loved ones are suffering. May God bless and comfort you and them. Trouble might be dirty air filter, OR might be malfunctuiong accelator pump in carburetor. That is the gizmo that squirts a bit of gas into carb thoat when governor kicks throttle open. If...

Not familiar with your model. However the ratio of pulley circumference and PTO shaft sheave circumference will give you a guidline. Then if you know engine RPM, you can calculate PTO rpm. If drifving pulley sheave same size as driven (PTO) sheave, same rpm as engine. If PTO sheave smaller...

Once last year I tried to raise deck on my 930 D2 Hopper. It was dead. All fuses in panel good. I went to 'weather pack' connector alongside lift motor, and noticed it was connected, but felt loose. Used long nose pliers to tighten female lug, reconnected, VOILA! Trouble vanished. Opened...

One day my powerfold deck failed to operate. (930 D2 Hopper) Figured no 12V getting to lift motor. Fuses in fuse panel OK. So I checked 'T' connector under seat and one of the two leads on it seemed loose. Using long nose pliers, I carefully compressed female fitting, reinserted male...

Last year one day, my 2011 Hopper 930 D2 started, then died after I released the ignition key. Repeated twice. Checked fuses in panel beneath seat, all good. Decided to look at the three inline chassis fuses down next to starter. One of them goes to fuel solenoid. It looked good, but I...

I replaced blades on my 930 D 72" Hopper with Stens brand blades. Not info you asked about, but have been satisfied with them. Deck belt too, and it's a whopper over 13 t long.

I have similar config on my 2011 930D2 Hopper. Front mount deck, PTO shaft supported by two pillow block bearing assemblies. Not sure what keeps shaft in place, but might just be at the very tail end where it terminates in sheave. I looked in my op manual, and I could not see enough detail on...

Look into carburetor accelerator pump. It is supposed to squirt extra gas into throat if governor throws throttle open. If it is plugged or even partially plugged, that would cause what you describe. A dirty air filter would cause it too. Governor malfunction can cause it too. Some...

Hammermechanicman has right idea. Mine went dead and it was the push on connector under the operator seat. Another time it was the push on connector at the actuator . Both times I siimply cleaned the male connecter, put light coat of petroleum jelly on it, and crimped the female connectors...

You might try eBay. Be sure to use original Hopper part number from your op manual, or call dealer to get part #. Lots of vendors on eBay include original part # in their heading. BE SURE TO POLISH IT AND TO APPLY NEVER SEIZE OR WHITE LITHIUM GREASE TO IT BEFORE REASSEMLY!!! Can save a ton...

I have 930 D2 , Kubota 30 hp. More power than I really need, and fuel consumption very reasonable. Mine is long chassis, front mount deck. I mostly cut at around 60-70 % throttle, never wide open. Never bogs down. Easy to spin a tire tho, and best to keep tires below 10 PSI.

Did you try to run the thing with the fuel cap off? Might it be a simple case of fuel tank vacuum lock? Can't hurt to try it. Did you hook up air line to fuel line and blow it out, TOWARDS THE TANK? I've cleared trouble on my track loader twice doing that. Thing is gravity feed thtu 2...

I think Bertsmobile is correct. Rust. Factory puts these mowers together DRY. That is why these parts rust in place, whether you store unit indoors or outdoors makes no difference. If PTO belts off, and engine still locked up, may be PTO shaft pillow block bearing assembly frozen. I have...

Could be as simple as tension too tight on belts. Or it may be that original owher got tired of tension springs breaking and installed some other means of maintaining belt tension. ( I did that on my 72" deck, no issues from it to date) Does your deck use tension spring, or is it mechanically...

Did you bother to disconnect both terminals and look back into wiring using an ohm meter? You might have an alternator or faulty start/ignition switch that is draining your battery. Costs nothing to check it out. Does alternator charge unit when running?

Do not pry it. Plastic housing likely to break. Definitely riveted in place, so ought to be easy to drill out, remove switch, install new handle grips, and reassemble. I'd almost take a look at using special sports grip tape over old foam. I have the 'curb hopper' option on my Hopper too...

I have 930D2 diesel unit. One day noticed grass discharge suddenly less, barely any coming out even tho was in tall grass. Figured my PTO clutch was slipping, so I turned off PTO, went to shop. Never thought to look back to see if clutch smoking, so can not say if it was or not. However when...

Forgot to mention two other reasons a Grasshopper engine can die when PTO is engaged. I have a 2011 , 930D2 diesel powered unit, front mount deck. Had 2 occasions when PTO engagement would kill engine. One time was defective 'E' relay. Other time was defective PTO switch. I don't know a...

You might have run the trouble to the deck. Could be either one of blade bearing-mandrel assemblies causing it, OR your engine is simply undersized, underpowered, OR you might have a faulty carburetor, say one with a bad accelerator pump. Could be solved by simply using an acetylene torch tip...

Even with it 'full', up to the 'full' plug, still 1/3 of the inside volume empty. So I doubt my filling it to 'full' plug will cause seal to leak/fail. Grasshopper ought to alter rock shield so that it has pair of 1" holes in rock shield to allow access to 'DRAIN' plug and to 'FULL' plug...

White smoke exhaust unlikely to be anyting other than coolant. If you put your hand in the smoke, is it damp? If so, definitely coolant. Does it continue as you operate the mower, or does it go away? Does it affect performance? Does it affect op temp? Maybe only doing it when unit is cold?

No vent on Grasshopper deck gear boxes. So overfilling could cause horiz shaft seal to leak for sure. However 'full' plug is only 2//3 way up total height of box from bottom when box horizontal. So I think one I received was low. No reason designer/ mfr made 'full' plug in wrong place. And...

If electrical overheating, you would smell the hot plastic, or worse, the coating on the alternator windings. Fuses supposed to cover that before wiring could get that hot anyway. If you can put your hand in the 'smoke' and it is damp, it is coolant. Only other white smoke I can think of is...

Roger. Removal would be to loosen belt, raise deck, remove stumprrock gaurd. Unt bolts to it, and is also surrounded by it to prevent damage. ONly thing holding it will be sheave above it in deck housing. Lower deck and loosen the two collar set screws that lock the sheave collar to the...

I had to replace gearbox on my 930D2. Could not drive up shaft out of sheave after removing the two lock bolts. 8 # sledge hammer, no good at all. So, To get sheave off, had to first remove rockstump shield beneath deck, behind baffle. Then had to remove all bolts holding case halves...

I have 930D2, 2011 model. My gear box is cast aluminum. On either side it has a drain, plug and a 'full' plug. Had to change it last year becuse it had run dry by time I'd bought it. THE NEW UNIT, EXACT FACTORY PART FROM MISSOURI, CAME WITH ONLYL 2/3 OF THE REUIRED OIL IN IT. I had to add...

Agree with previous post. Check to see that pulley'/ sheave is firmly fixed to shaft. Could be that simple. Hydro pumps do fafil more commonly than the hydro motors do. But 300 hrs is nothing to a 930D series. Guessing loose component from what you say.

Spring aids tension, also lessens shock when PTO engaged. Spring on my 930D2 hooked to threaded rod J hook. I had to adjust mine as belts seated and stretched. Owner operator manual gives correct length of spring coil portion when properly adjusted. (ditto for deck belt tensioner) Belt should...

Check pto belt tension. Won't always squeal until heavier cutting encountered. If air filter, you'll see sooty looking exhaust when load increases.

Was going to tell you check level of gear oil. in gearbox. WARNING. I ordered and installed a new gearbox on my 930D. (around $250 on eBay) When I took it out of the box, I laid it on my work bench and checked oil level. Thing was only 2/3 full. Supposed to have oil enough to reach...

Hate to say it, but white smoke is most often steam. How is coolant level in radiator?

RECENTLY BOUGHT 2013 GRASSHOPPER 930D2. Dies when I engage blades. Have noticed when under it putting new belts on PTO that i can hand-turn the drive shaft to deck, and it turns smoothly and then stops, reverse direction ditto. No metallic noise, just stops. Thought odd, but figured when...
