kubota zd21

I am the very well satisfied owner of a Kubota ZD21 but it has been suffering with a starter issue for several years and I would like to fix it. The starter motor seems to run fine but the gear very often doesn’t engage to turn over the engine, do you think just replacing the solenoid or...

Hello, Brought home a 2006 ZD21 with a 60" Pro deck today. Kubotabooks has the WSM but not the owner's manual. Does anyone have the owner's manual in digital form? I have the WSM if anyone needs it. Thank you

What oil goes in the transmission on a ZD21 mower?

I forget if there’s kerosene or diesel in my yellow gas can, if it’s kerosene will it hurt it? I have about a quarter tank of diesel in my mower, so it would be diluted a bit.

I am having issues starting my Kubota ZD21. It will only start if I hook a high voltage jump starter to it. Any ideas??

I have replaced the starter, solenoid and the ignition key switch. Now I知 finding a safety switch is faulty. How difficult is it to replace a steering arm switch?

Is there an adjustment on the arms to reduce the play. Both sides work fine but there is play in the arm before it touches the pump. I hope I have explained this so that it is understandable.

Figured I'd post info for anyone who might have had this problem. My mower started just fine. I'd mow for a few minutes, then it would drop RPM to barely running, and sometimes would stall out. I could mow the yard with this happening about 5-6 times. It only lasted for a few seconds, then...

Hello, I recently picked up a Kubota ZD21 60" deck unit. I was able to find the service manual online for it but only a ZD221 owners manual to download. Not the ZD21. Does anyone have a PDF I could kindly get a copy of? BB

Hopefully cracking the case open tonight. I have to take the fender off, fuel tank, left axle, and then I should be able to get to the hydro. Problem is, messick's is listing two models, C45702 and C45703, with very subtle differences. Any idea how I know which one I have? If it's a model year...

I was hunting for a diesel motor for a generator project, when I came across a craigslist add for a 21hp kubota 3cyl motor with less than 1000 hours for $500. Accessories included an entire zero turn mower and spare set of turf tires. Turns out the left hydro lost reverse due to the common...

I recently bought a ZD21 with 2000 hours on it. It runs and cuts great but the only way I know to start it is to push the back of the electric controller with a screwdriver. When I push in the small brass plate on the back of the small electric control box, kubota calls it a controller and it...

I'm located near St Louis MO and am looking at a very nice 2003 Kubota ZD21 (standard deck) with ~1000 hours for $4750.00. I'm happy with the $4750 and most likely will buy it. However, he has an identical unit with ~1000 hours that is missing the engine assembly. (no seat, roll bar, radiator...

I'll start by saying I'm not mechanically inclined. I am a registered nurse so when you say solenoid or fuse please be specific because there is a good chance that you just went over my head. Given this, I'm an intelligent man and I trouble shoot most things rather well. Last week my wife ran...

The left drive wheel locks up when I move the control level from the forward position back to the neutral position. It has just started this. It seems to act as if the lever has been pulled past the neutral position into the reverse position and the tire is trying to instantly change rotation...

my deck wont raise on my zd21 Kubota zero turn

Local John Deere dealer has a well used ZD21 (3400 hours). Paint is faded bad but it didn't look beat up. Is it worth looking at for the right price? I'd probably give $2500 for it if it runs good and hydrostatic is strong. Current husqvarna zero turn is gas and I always though it would be...

I have the service manual for my ZD21, but can not find the specs for the small electric lift pump. Does anyone know the pressure or volume of these pumps? Any help is appreciated. Thank you.

Just got my ZD21 back from service and I got lucky and I have a great dealer(Horizon Lawn and Tractor). I was worried that one of the transmissions was going out. One side was not going as fast as the other and it was making a bit of screeching noise when i moved that side of the lever. Talked...

Hi all, I am after an electronic copy of the owmers/operating manual. Can anyone help?

I have a ZD21 with about 425 hours on it and love it and have very few problems. Recently while cutting a field, I set the brake, locked the handle controls and disengaged the PTO in order to dismount to remove an obstacle from the cutting path. I have done this countless times without issue...

Hi, Can anyone tell me how to get the injection pump off of my ZD21? The pump will come lose, but will not come out. The ZD28 has a plate on the block that you can get a pry tool in allowing the pump to be removed, but the ZD21 does not have that. Thank you.....Shawn

hey guys, im new here so any help would be greatly appreciated, i have a 2002 kubota zd21 with 720 hours that i just found out that cylinders #1 and 3 are shot and the engine needs to be rebuilt, from what i understand it was caused do to overheating, the local kubota dealership changed the...

Hi all, I have a zd21 that i bought new in 2002. It will crank but it wont start. last time i used the mower it wouldnt stop when i turned the key off. it idled rough but wouldnt quit. i throttled it down, stood up, engaged the arms with the brake on and it wouldnt quit. finally it did...

Hey. I have a Kubota zd21 with 700 hrs. The problem that I am having is when I try to go up a hill the motor will bog down. I then have to stop for about 10-15 seconds and the mower will regain power. It runs like a new one unless I try to go up a hill. I am the original owner and haven't...

I have a Kubota ZD21 mower that will not start. I mean when you turn the switch nothing happens. The gauges do not move, the fuel pump does not click etc. I bought a new battery, new 40 amp fuse and checked the 5 other fuses. Does any body have any ideas on what to try next? Thanks, Jim

Aloha all, My ZD21 mower is overheating. I had a bunch of grass in the radiator fins and it overheated. I blew out all the grass, let it cool down. Now it overheats almost immediately. I'm trying to isolate and discover the problem. The radiator gets hot on the top, including the hose...

I just picked up a Kubota ZD21 from CL the other night. It works great but would like to pick up a set of owner/shop manuals. Where is the best/cheapest place to find these? Thanks !!

Hi Guys. I just bought a Kubota ZD21. I asked what year it was and the guy said he wasn't sure, but he thought his dad bought it around 2007. The thing is in excellent shape. Just a couple scuffs on the deck - nothing major. It has 500 hours on it and I was told it was never used commercially...

To quote Homer Simpson "DOH" Long story short, overheated the D782 diesel engine in my ZD21F mower. Looking for a replacement D782 engine is analogous to finding a needle in the haystack. However there are a lot of Kubota D902, D1005 and D1105 engines available both new and remanufactured...

I'm looking at help figuring out the value of a used Kubota. Used prices seem to be all over the map and I don't want to outrageously overpay for a zero-turn. Anyways, whats a fair price for one of these diesel zero turns mowers? I've seen units with a couple hundred hours to about 2000 hours...

I have this Kubota ZD21 Diesel tractor. After mowing the grass I turned the tractor off. It did not stop for about two minutes. I tried again and it did the same thing. I then engaged the mowing deck and stood up. The Tractor kept of running. I disengaged the mowing deck and then waited a...

Fuel gauge reads full as soon as you turn on key and stays there until you turn off key. Anyone had this happen to their unit? Any ideas of what problem might be? I am wondering if it might be the gauge or something wrong in tank. Any help would be appriciated. Darn sure don't want to run the...

Hey everyone. I purchased a new ZD21 and B7610 back in 2004.After my purchase I read that my model has tranny issues.I expressed my concern to my dealer.I told them of a retro kit available (read from this forum).I offered to pay for it.They said don't worry about it.I always had p m/service...

I have a zd21 with a 60 inch deck. Last week I noticed that the engine lugged when I tried to raise the deck. By the time I finished mowing, it would not raise the deck unless the engine ran a full RPM with the blades disengaged. When I checked it the next day when the engine was cold, the...

It has 1000 hours and a fairly new battery. It doesn't crank at all, just a click when I turn the key to start. Prior to replacing the battery recently it wouldn't always start when hot. Now it won't start when cold. Cold is relative, since the temp is in the 90's. Ideas?

I asked questions last week about fixing the drivers side gear box on my mower. I just don't have time, so I think it will be parted out or just sold. If I were to sell it can anyone give me an idea of what to ask? Everything else works great, with a huge stack of maint records. Thanks for...

Hello all this is my first post and wanted to introduce myself. I have a small farm here in Washington state and have a few tractors and this one mower, and I am adicted to tractors. :D Anyhow my problem is I have a 2002 ZD21 that I purchased from my father in laws work, it has high hours...

We have a 2003 ZD21 that was running fine until today and then it just cut off while mowing like the fuel just quit pumping. After a few minutes it started back up again but soon did it all over again.Has anyone else had a problem like this? Donny

Hello fellow Kubota owners, I have a ZD21 60" mower with a leveling problem. The whole mower looks crooked. We noticed it was not cutting evenly and so I inspected the mower more closely. Before I started trying to level the deck, I noticed the entire mower looked uneven, as if one of the...

I have an older ZD21 zero turn mower that has an oil leak at the cover for the left side brake actuator arm. After removing the cover I realized that there is a fair amount of gear oil in the area of the brake drum and shoes. Is this area supposed to have oil in it or is it supposed to be dry...

Does anyone know if a ZD28 engine will bolt directly into a ZD21 mower? If not, what needs to be done to allow use of this engine? thanks

Does anyone know if a ZD28 engine will bolt directly into a ZD21 mower? If not, what needs to be done to allow use of this engine? thanks

just bought a 2002 ZD21 for $3500. Are these good mowers? Did I do ok on price? Where can i get a owners manual? Any experience with these mowers? Reason I went with this was my Woods 6180,s Briggs 18 hp Vanguard blew up with 750hr and the motor was going to have to be replaced at about...

I just purchased a Kubota ZD21 runs great but every once in awhile it looses power, I pulled the tank, cleaned out totally, replaced all fuel lines,still having problem, I noticed today the fuel filter after the fuel pump is only 1/4 full, I tried to bleed it, removed hose and shifted filter in...

Just took over a property and have a Kabota ZD21 that I need some start up pointers on? The regular person used it fine 10 days ago. They moved. We are just caring for the place, while our special needs son attends a great school. Thanks, mr fishhead

Hello, I have a Kubota ZD21 mower. It is 8 years old and I have never had a problem with it until recently. When I get on the mower and start to crank it, sometimes the motor will fire right off and sometimes it will sit there and turn over but never crank. I wait until the glow plug...

The wife wants a Zero turn.... so I looked at a used one this week, 2006 W/804 hrs. asking $5000 which I think is too much, I offered $4500 and haven't heard back, it looked good but obviously used. Today we're going to a farm auction and they have a 2001 ZD21 W/141 hrs. My question, what are...

After researching for over 2 years I decided I was ready for my upgrade from my BX22 (which by the way was a awesome tractor) to a larger B platform. I felt the new B2920 was a perfect fit for my needs present and future offering more HP for ground engagements as well as a larger platform (but...

A friend of mine has a Kubota ZD21 mower with a pro deck and it has a bent lift arm.Is there a place to find a breakdown of the mowing deck to see exactly what the part is called? Thanks for any information. Donny

Spraying has worked well for me for weed control, but with no foam marker system sometimes it is hard to see where I have sprayed. Also, with lots of trees it is hard to get good coverage with a 20' boom. This is my solution: This sprayer rack I made fits into the ROPS holes on my ZD21 mower...

I'm looking at a ZD21 with 190 hrs and stamped deck. It was originally purchased in April 2004. It looks very clean and runs and drives great. Any opinions as to what a fair price would be? Does $6000 sound reasonable? Does the stamped vs pro deck make that much difference?

I have a ZD21 I couldn't be happier with. What are the differences between the 21 and 321 for $3000?

I've been looking at new ZTR mowers again. I had a bad experience with a cub z-force 44 and I'm in the hole pretty bad (money wise)and I'm now looking at a better model.I think I want a ZD21 Kubota.I looked at them and really like the quality.How many hours do you have on yours and what are some...

Hi everyone! Just wanted your thoughts on a price of $8960 that I just got from my local Kubota dealer. It's a brand new ZD21 (60") and it comes with free delivery. He says he needs to move it cause he'll have to pay Kubota a fee soon. Is that a good price? He offered a 36 month 0% financing...

can anyone tell me where the filler hole is for the hydraulic lift for the mower deck? I bought a used ZD21 and it was working fine until now. The deck will not lower, it acts like it need hydraulic fluid, but I can see a place to add it anywhere. If you have had this problem before I would...

I recently purchased a used Zd21. It worked very well except now, the hydraulic lift will not lower the deck. I think it needs hydraulic fluid but ido not see a filler hole. If anyone has an answer I would appreciate it very much! I do not have dealer close enough to take it, besides I like...

I am looking at a 2003 ZD21-60" pro deck - 485 hours. It was used commercially for 2 years. Any opinions as to the value of this machine??

Dealer delivered a ZD21 for me to try out tonite. I'm about to pull the trigger (trading G1900 4ws) but need to know if a trailer hitch is available and if so (or even if its not), has anyone that has a ZD21, ZD25 or ZD28 used it for towing anything? Should've asked the dealer, but it slipped...

I'm currently looking at buying a ZD 21 My local dealer has 9 in stock and doesnot want to deal. He says sticker is more than fair.And I had bugeted myself for something about $3500.00 less in price but would be willing to meet him inbetween but he won't budge. I don't mind driving 4-6 hours to...

I have a ZD21 with stamped deck not Pro Deck . Are mulch kits availale for this mower?? Anyone have one? If so, how do you like it? Thanks.

I have found a used '02 ZD21 mower with approx. 180 hrs on it for $5750.00. Is this in line for used or should I write a check for it tomorrow? It seems to be in good shape except for couple of dings in hood.

Geez, where has this thing been all my life??? The ZD-21 is awesome! Super powerful, smooth, quiet, low noise and vibration, and a great economical cutting machine. Have only put 10 hours on it since new but I am very impressed with the production quality of this machine, it is a workhorse...

I have a Kubota ZD21 zero turn mower, I need some ideas on how I can fabricate a hitch to pull light equipment, roller, aereator, etc. Anybody have any ideas?

I am thinking of trading my Kubota ZD21 for a Kubota F2560 or F3060 frontrunner because I need a snowblower. Have any of you guys had any experience with the Kubota F series mowers? Can i expect the cut be as good as the ZD21? Also, I am looking at the rear discharge deck, how good is the cut...

Has anyone expirimented with removing the baffles from a Pro 60" deck? If so what were the results.

I am going to be taking delivery of a new ZD21 shortly, I need some advice on motor oil. Do most of you use Kubota oil and filters? I was planing on using 15W40 Rotella like I use in my Powerstroke pickup engine. As for filters I was going to use Kubota filters in case of a engine problem but...

Kubota has recently changed their deck design on the ZD21 and ZD28 zero turn mowers. They went from a stamped deck to a welded deck. Does anyone have any experience with the new welded deck design? Do they mow better than the stamped deck? Any info would be appreciated!! Jon

Well, it's that time. I have a few questions for the group. The Manual calls for 10W30 in my temperature range. It doesn't even mention 15W40. Have we decided whether or not Kubota oil is any better than RotellaT? What about the Rotella Synthetic? Has anyone had any experience with it...

We are looking at buying a ZD21 zero turn radius mower. Has anyone had any problems with one? How smooth and comfortable are they to mow with? In general, what do you think of them?

For anyone interested, there is a ZD21 w/150 hrs on EBay. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1302852776&r=0&t=0&showTutorial=0&ed=1007698301&indexURL=0&rd=1

Testing, testing, one, two, three. ...my first photo post.

I am curious how these two units stack up against each other as grass cutting machines. I had narrowed my search to the BX, but this ZD thing may be a more versaltile grass cutter. My questions are few. Can the BX cut as fast as the ZD. That is not a loaded question. :) In a straight line...

Hello all. I would like to hear from some ZDxx owners to see how you like the unit. I cant seem to find a dealer that has one in stock. From local to across the country, everybody has at least a three week waiting list. I have 2 flat acres, and will cut a couple yards on the side to help...
