Kubota Z100 Series

The bad news just keeps coming – Purchased in March 2015, brand new. Now has 350 hours. The day the machine arrived and was started the first time, the tappet cover developed a leak. The cover was loose - doesn't the dealer supposed to check the machine prior to delivery? The ignition switch had to be replaced @ 150 hours. The transmission brake shafts (2) started to leak @200… Read more

hours. Both transmissions were replaced. A second ignition switch was replaced @ 220 hours. Deck belt broke @250 hours - cost of belt alone over $200. Replaced deck belt tensioner and guide pulleys at the same time, as the bearings were noisy. They didn't cause the belt to break. Now out of warranty and the transmission brake shafts started to leak again, on both transmissions @300 hours. Obviously this is an inherent design/manufacturing fault and should be repaired by Kubota at no charge to the customer, but that is not the case, according to Ongmac Trading - the agent for the brand - and Kubota - both of whom I've contacted. The transmission belt broke @340 hours. The machine is looked after, has been serviced regularly, cleaned after each use - including the removal of the belt covers to clean grass clippings trapped. I would not buy another product for Kubota and warn other potential buyers to be wary of the brand.

comfortable and easy to operate – the Z121s operates well and is smooth and responsive to handle. have a farm and it mows lawns well but struggles in the heavier grass. (live in tropical north Queensland and the grass grows quickly). It struggles with long grass or weeds because of the anti-scalping guards but I need this feature ( some operators fit extensions on the spigots). I… Read more

have 200 hours and no belt problems but the machine is cleaned with a blower My wife loves this machine as it is fast easy and comfortable. This machine deserves fold down ROPs and a fuel gauge. when filling one needs lift the seat to view the tank or have a second person watch the gauge. The throttle mechanism is flimsy and awkward to set. The style of the mower is cluttered and catches leaves and debris when mowing. The Kolher engine is heavy on fuel and has no mixture adjustment. should have taken a Briggs and Straton. The fuel line has tap in top of the tank on a bend and this has BLOCKED with fibre on several occasions. For my use I would sometimes like a higher top speed. The spigot bearings have no protection against wrapping with string or fibre and I replaced the original Chinese bearings with SKF at 40 hours and fitted protection for the bearings.

Who knew?! – Comfortable ride, mows nicely. However...can't put bagger on ( or take off) without two people. The bolts are under the shoot so far, that you need to get under it to tighten or loosen. Your choice is to lie on the ground or put the machine on a jack either way, still 2 people needed. Very poor design. Took it in for general servicing, and… Read more

told the tech my problem. He soldered the bolts on the deck from the bottom up - thought that was nice of him. Now can't put my grass shield or the grass catcher on because they don't fit between the bolts. Since brand new the grass builds up in the mower deck to the point of slowing the blades. Again, jack, get under with putty knife and scrape clean - at least once a month. Thought it was just my machine but have since talked with other owners who have the same problem. If you think you need a blocker (which I also purchased) or a bagger, I can not recommend this machine. However, if you simply need to mow, its a very nice machine.

TOUGH LITTLE MOWER – I purchased my Kubota Z125EBR in 2015 apart from a change of blades and a couple of belts this mower has been great. I have approx 5 acres I mow regularly and I don't baby my mower I have it serviced by Kentan Hexham from where I purchased and they have been great to deal with as well. I would definitely buy another Kubota. Show details

Can’t complain. It’s a beast. Not good going down hills – I bought new in 2016. I change the oil and filter ever 50 hrs. I change the blades every 100 or sharpen them. I have replaced the left side mower leveler wheel twice. I keep the belts clean under the guards. Despite all the bad reviews I have never had an issue. 320 hrs so far.‍Just very dusty to mow. Eventually I will go back to a tractor for… Read more

less dust. I mow 5 acres with it. Dry to damp grass I can mow around 4 acres on a tank of gas It’s pretty comfortable. I had a recall and tried to schedule it twice. No luck dealer sucks in BLOOMSBURG PA

Wish the dang belt would stay on!!!! – Very poor belt tensioner design. Deck belt constantly coming off even with new belt. Pain to put back on. I'm pleased with other attributes. Would not buy another one because the deck belt is so frustrating. I mow 3 acres of fescue lawn every week. The machine uses 4 and a half gallons of gas for each mowing. Mows good and blows the heck out of leaves in the fall. Show details

Great from day one – Couldn't be happier with this mower. Had mulching kit fitted at dealer. Mow 5000 sq meters twice a week in summer. Keep my own services up. Have had for 7 years , only done 2 belts and have replaced deck bearings once. Only gripe is all of the little holders they put on them good for nothing except filling up with leaves and grass. Show details

hopefully no more bad news – 330 hrs on my kubota z125s/ replace ignition and pto switch/ replaced 1 belt pully due to bearing failure inc belt/ replaced another belt due to worn washer on belt tensioner arm creating improper belt travel/ hard to start due to improper choke cable hookup-it was in wrong hole/replaced clutch due to intermittent short blowing fuses until bench… Read more

test/ less than 100 hrs valve cover leaking replace gasket / . crankcase plug{ in block} fell out at 150 hrs lucky for me i caught it as it fell out./some of these issues required 2 to 3 trips back to dealer to resolve./ cut 4 acres native bermuda on semi flat terrain with few trees/comfortable ride/never cut lower than 3in/other than these issues wife loves this machine since she mows.

Properly useless design – Difficult to work on, and I spend as much time working on this machine, as working with it. Machine keeps throwing belts off pulleys which are a proper pain to re-fit or replace. Tyres fitted to it cannot be replaced with anything but the originals, which are more expensive than those for my car. They also have no grip on grass with any moisture… Read more

on it. Wish I had bought something else. Also bought one of their push mowers, which simply cannot mow grass. Replaced that with a Honda which works beautifully. Level of care from Kubota? Zero.

kubota belt eater – purchased this september 2019 thanking i had made a good purchase . after 33 hours broke blade belt 128 dollars three. weeks later 42 hours drive belt broke dealer on help no way to contact kubota USA if it happens again soon i will take back to dealer and let them have this garbage back Show details

nothing but problems – We purchased our mower new in approximately 2015. Since then we've, early on, had to have cut out switches replaced as originals were faulty. Then engine developed oil leak, had repaired then another oil leak, also supposedly repaired but repairer couldn't get the machine to run properly. Then we're told it has cooked motor. Even though its… Read more

always had oil. Only 700hours use on machine. We have now been waiting 9 months for a replacement engine. Absolutely never will buy Kubota again.

Oakdale Motors Kubota Junk – 3 yr old mower now , junk from day one , belt comes off at least once and will snap in two at least 3 to 4 times a year changed bearing twice drive belt once and dealer just says it’s sticks doing it, omg I would not recommend the z122e 48 inch cut to anyone, biggest disappointment is the dealer doesn’t care , asked if it had a recall he said check the internet, I’m beyond frustrated, I need suggestions on a different mower to purchase Show details

really disapointed – I bought this thinking I was buying a quality zero turn . Have owned this Z121s for 4 years, and broke down 4 times under warranty micro switches 2time ,drive belt pulley wheel broke 1 time ,drive belt 1 time after 50 hours and its being picked up next week because it stopped run while I was mowing ? Could not recommend to a friend . Show details

I cannot in good conscience leave any where close to a positive review – Kubota did not live up to the hype on this one. I purchased two hours away thinking I would get a better experience then the locals. The original purchase was fine. Trailered it home and on the second use, threw a belt. I inspected and put back on and made adjustments underneath and no problem with that since. Around that time though the Kommander… Read more

started dying mid mow. It would start back up right away so I finished the season after replacing the air cleaner and fuel filter. I trailered it back to the dealer and told them they could work on it at their leisure since i no longer needed it for the year. A couple months go by and I decided to pick it back up to find a bill for somewhere in the range of $150. I wasn’t happy however they told me the problem was dirty gas. That was possible I suppose but I was skeptical. I trailered it two hours back home feeling reassured they handled the issue. They did not. I mowed half my lawn to have it die again. Even under warranty I was scared to take it all the way back to have them possibly charge me again. I fix my own stuff so I decided to trouble shoot the issue. I’ve bypassed A multitude of switches, replace And bypassed fuel filter, installed an electric fuel pump, replaced plugs, solenoid, fuel lines, more fuel filters, battery, wires, tightened and cleaned grounds and power leads, cleaned and flushed carb a few times, rerouted fuel lines and wiring away from heat sources. Checked and double checked spark plugs and gaps, coil gaps et al. It still quits after it warms up. Usually about three attempts to mow about an acre. The LED lights are neat and the deck is built like a tank. With 150 hours on it now I’m throwing in the towel. The service center in Omaha is far from helpful as apparently I’m responsible for the “dirty gas” I put in and the salesman washed his hands of me the moment I left the dealer with it. Not My Kubota. I’m ready for a Grasshopper.

Happy so far – I purchased the z121s last year to replace an Exmark Quest i had the previous 10 years. As far as quality goes its made to be a residential mower, not commercial. The build quality to me is on par if not better than some. I have roughly 22hrs on the mower now and have only had one problem and that was the hour meter. It jumped from 2.5 to 40hrs in… Read more

the first hour of use, but my dealer replaced it and i have not had any other problem as of yet. My only concern is the Kohler engine, and if it will hold up after years of use. I think Kawasaki are better engines for sure and an upgrade to those engines would help sell these better. Overall I am pleased and would recommend testing one and comparing it to others to see if it fits your needs.

Keeps stopping Z121S – Purchased this new and have had this mower for a few years now. Worked really well for first 40 hours. Since then constantly won't start. Also kept cutting out. they replace 1 of the 2 coils and this seemed OK. Now it won't start and appears to be one of the cut of switches. Maybe park brake or seat. Haven't resolve it yet. To have these problems after 42 hours of use seems problematic given the purchase price. Show details

When its going cant beat it - belt problem also hopefully fixed – This is my second Kubota Zero turn , first one was a Z122e 48" with Briggs and Stratton 22 hp. Traded after 120 hrs , had a pretty good run except head gasket went just before warranty was up , didn't have to pay so all good. Never broke a belt , dislodged twice by stick and son wasn't mowers fault....this is why I bought another one.........but… Read more

with in 7 hours of having the Z125s 54" kohler 25hp? had broken a belt , then 30 mins later had scored another one . Called out service guy from where I purchased it and said I had noticed this mower was scalping and the second belt had twisted on the deck pulleys . Turns out they had never performed the pre-delivery service, so the mower had flat tyres, the horizontal deck alignment was out and the front deck wheels were in the wrong position. Since getting all this right I have now done 10 more hours and going well. Having said all this I still believe the larger area of the deck creates more leverage and a greater risk to dislodging the belt when mowing around uneven/lumpy areas. Great mower , heaps of power and new sharp blades give a great cut . I was furious when these belts started breaking on my new $8000k mower , so I hope this helps those of you still having issues with this.
