    Your last generator Maintenance Run

    If your generator setup requires switching the main breaker, instead you need to have a properly installed shutoff switch ahead of the main breaker and use this instead since it is intended for this type of high cycle service. But with the expense of this, it would be worth looking into a...

    Your last generator Maintenance Run

    Although my ATS can be programmed to automatically run a regular test/exercise run, I do a manual test instead once a month and this is primarily so that I can arrange to put a heavy load on the generator. The exercise run is a good time to take a shower (deep well pump plus electric water...

    Your last generator Maintenance Run

    Mine auto started this morning shortly before 6 after a brief interruption. I decided to turn it into an exercise cycle so that it would get up to operating temp under load instead of shutting back down after monitoring the line for 5 minutes for another power dropout. The cats didn't...

    Uncle's JD 4230

    It would be nice if the tires would hold a little air to make the roll more easily but the front axle center section is very beefy on this vintage and it should be a safe winch point for any tractor that hasn't partially buried itself in the ground. Since you want the tractor facing forward on...

    Your last generator Maintenance Run

    Dave, Attached is the photo of one of mine, I use one at the service entrance where the main line comes into the property and my transfer switch is located and then the barn, garage, tractor outbuilding, and house breaker panels all have their own units. They have to be connected through a 50...

    Uncle's JD 4230

    WD-40 is effectively a blend of very light petroleum distillates more flammable than diesel and not as volatile as gasoline or ether so it is a safer alternative than ether but not as effective for a hard starting diesel in cold weather. As I recall, for a brief period GM was recommending it as...

    Parallel or perpendicular blade orientation when mounting 3 blades to a mower deck?

    Fortunately that doesn't seem to be a problem with the museum. I got to know one of the volunteers there and he told me that damage to new vehicles hasn't been an issue... Except from the new owners. When I picked up my Z06 in 2016 (second year of production), the unofficial count at that...

    Parallel or perpendicular blade orientation when mounting 3 blades to a mower deck?

    And even if the blade doesn't slip, the belt and pulley setup isn't a precision design so there will be some rotational difference between spindles. Cog type belts are used where precise timing/sync is needed but the cogs aren't so much to avoid slippage but instead ensure that the rotation is...

    Parallel or perpendicular blade orientation when mounting 3 blades to a mower deck?

    Dave, that makes sense and with as much trouble as it is to mount the extremely wide low profile tires on these cars (285/30ZR19 front and 335/25ZR20 rear) I could understand a picky customer wanting that done. But this person was loudly pointing out that the valve stems weren't at the same...

    Parallel or perpendicular blade orientation when mounting 3 blades to a mower deck?

    When I took delivery of my Corvette Z06 at the museum in 2016, another customer was complaining that the valve stems on his car weren't all in the same position. I thought at first he was joking with his delivery person but the fool was serious. Rodger

    Baumalight PTO Generator

    I thought about a PTO driven generator but when power fails you still have to hook it up and start the tractor so there is a convenience issue and also a problem if you are traveling because of food spoilage/freezing pipes, etc. After dealing with a 7.5KW gas portable for 14 years, I...

    Your last generator Maintenance Run

    Power reliability has improved here so probably 4 to 5 per year, usually only 4 to 5 hours at a time but it did run 30 hours straight after an ice storm the year I installed it. PDG quotes 2.4 GPH at full rated load, in typical use I have averaged about 1 GPH and even during a summer outage...

    Your last generator Maintenance Run

    I expect your generator has a very long life ahead of it. I looked at a company that was using GM's industrial engine line that are set up for natural gas or propane but I am too far out in the country for natural gas and for propane I would have needed another tank to ensure fast enough...

    From PDG in Georgia, a large selection of generators and excellent customer service. They set up shipping and make the entire process very simple. The Asco transfer switch came from a distributor in Texas. Rodger

    Your last generator Maintenance Run

    Thanks Dave! I installed it 4 years ago after getting along with a 7.5 KW gas portable for many years. But I got tired of starting the generator, wheeling it from the barn to the house, and then plugging it in and throwing a transfer switch. It seemed most power failures were at night during...

    Going underground

    There is a company near me that builds what they call "cave homes" in the sides of hills and I can see the attraction given tornadoes/hail/severe storms along with the excellent insulation. Sort of a throwback to the original "Little House on the Prairie" series :) But Florida would be one of...

    Anyone experienced increased NO2 emissions on modern tractors with DPF?

    I really like having the slider rear window in my crew cab pickups but I close it in my 2018 GMC when I am in a little town with lots of stop signs or in stop and go traffic because too often I get a whiff of the DEF "enriched" exhaust. This is a constant feature of Tier IV and not the short...

    Anyone experienced increased NO2 emissions on modern tractors with DPF?

    Fortunately I don't need that quantity of DEF for my pickup so I either add at a station or buy Kleen DEF at Farm and Fleet in the 2.5 gallon containers when they are on sale. Freezing won't hurt it but long storage in hot temperature (including sitting in the tank of a pickup that is only...

    Anyone experienced increased NO2 emissions on modern tractors with DPF?

    Does your tractor also use DEF? Most Tier IV compliant will and these use a SCR (selective catalytic reduction) system that injects DEF (diesel exhaust fluid which is a specific concentration of ammonia). In the SCR, the DEF reacts with the exhaust converting the various NOX products. There...

    1966 John Deere 110 Riding Lawnmower Mystery Tool

    I restore vintage amateur radio gear and this equipment often contains undocumented (and BAD) changes from a previous owner. Except in the extremely rare case where changes are documented AND actually well designed/implemented, I take gear back to factory stock as part of restoration. Rodger

    1966 John Deere 110 Riding Lawnmower Mystery Tool

    I think he must have built it to release the tension on the belt tension pulley for belt changes/deck maintenance. Could the wood block be inserted to hold the spring in its stretched position once the main tool has released the tension? Probably the deck height position would change how much...

    955 Deere

    I bought a 955 with loader, 72" midmount, tiller, and 3 pt rotary mower when I bought my place in 1994 and it has severed me well with nothing beyond normal maintenance items. The only annoying items were the idler pulleys on the midmount mower deck required replacement several times, the deck...

    F series deck minor wheel issue

    At 90 hours on my F2690, I had the first minor issue. I have the 72" rear discharge deck and I noticed one of the front deck gauge wheels wasn't running true. I knew I hadn't hit anything hard enough to damage it and the problem was 3 of the 4 nuts holding the two wheel halves together on the...

    Vehicle Oil changes

    My dealerships are about a 30 minute drive away so that would turn a short job into at least 90 minutes with transit time and waiting at the dealership. I bought a set of 2 piece Race Ramps when I took delivery of my 2016 Corvette Z06 and I also use these for my Camaro and Cadillac CT5 V. Once...

    Walker's F Series Thread

    I am now into my second season with my F2690 equipped with the 72" rear discharge and I still love it. I mowed for close to 30 years with my Deere 955 with 72" midmount and the Kubota has pretty much retired the Deere from mowing service so it is mostly used with loader, blade, and rear rotary...

    Running Hot(er)

    Rip, Over fueling (leaky injector, poor spray pattern) will cause the engine to run hotter but normally with that you will see a lot of smoke and also have poor running. Late injection will also increase heat but that is a pump timing issue that generally results from incorrect adjustment and...

    Running Hot(er)

    Diesels don't run lean in the sense the term is used for spark ignition gas engines, they aren't like gas engines where a lean mixture results in hotter combustion. At a "lean" mixture, diesel engines run extremely cool. At idle and at very low load, a diesel is typically operating in the...

    Running Hot(er)

    I have seen water pump impellers in other applications losing effectiveness due to wear with higher operating hours. Water pumps don't just fail because of seal or bearing issues, the impeller can also wear with age resulting in less circulation. It is also worth checking the hoses. It isn't...

    Walker's F Series Thread

    If the majority of it is leaking out then the seal is damaged. If it were just seeping a bit, I would check the vent but a clogged vent won't create that much fluid loss. It is good that you caught it in time so that hopefully a seal is all it needs but while it is out I would seriously...

    Kubota F series

    I can't remember the exact design of the spindle bearings but I suspect one of the bearings has a damaged roller or ball that is creating the issue when it rotates to the point that the damaged spot is in contact with the spindle shaft allowing excessive shaft clearance. Rodger

    Looking for Front Mounted Mower - F Series Suggestions

    I bought a new F2690 and getting this setup is something I should have done years ago. It provides a much smoother cut than my Deere 955 with midmount mower and it does it faster. With 5 acres of varying ground (terrain and roughness), a zero turn wouldn't be a good match but the front mount...

    Kubota Diesel Zero Turn Questions

    I have the same D1105 Kubota engine in my F2690 as your ZD1211 and it has no problem with the 72" deck. I do have the rear discharge deck which probably takes a little less HP in heavy grass since discharge is across the entire width of the deck instead of funneling the clippings into a smaller...

    PTO Generator inadequate for larger HP motors?

    For a number of years I ran the well pump with a 7.5KW portable gas generator. It worked but was a pain. I would shut off all the other stuff when I needed the well pump to run. It was also no fun moving the generator and setting it up when power went out, usually late at night during a...

    Kubota ZD1211 Mower Gearbox oil

    One thing to keep in mind is that the number specs in gear lube and motor oil are scaled differently. 30W "motor oil" viscosity is roughly equivalent to a SAE 75 gear oil while SAE 90 would equate to 50W. Of course the additive packages are different. So the difference between those two...

    Kubota F series

    Art, I suspect the 90 series (and maybe just the 2690) is different enough that it doesn't tilt all the way with the PTO shaft connected. It will go most of the way but there isn't quite enough clearance to reach the point where the locking pin can be engaged. I really like the ease of...

    Kubota F series

    I have now mowed about 10 times with my new F-2690 with 72" rear discharge deck and I am VERY happy with it. It is faster than my Deere 955 with 72" midmount deck and the cut quality is so much better since I don't have heavy tractor wheels pushing down the grass before the mower blades. It...

    BX1500: using med mower and rear tiller back and forth

    Late to the party but if the Kubota tiller is like the Deere I use with my 955 compact utility, the key to easy mounting of the tiller is to attach the lift arms and then the PTO shaft. With the Deere compact, the PTO shaft is locked with the PTO shut off and driving the tractor a few inches...

    Need help choosing a new Kubota mower

    An important point and I would add that tractors are designed knowing that fluid filled tires are going to be used but that isn't true for typical ZTR designs. So when you hit a "terrain feature" that suddenly causes that weighted tire to generate high stress on the rest of the machine you may...

    How ofter do you really grease all your zerk fittings on your F mower?

    I went through all of mine before the first mowing in case the dealer missed any and my plan is to do them every 15-20 hours. I haven't found any of them hard to access like several on my Deere 955 with midmount deck which have less than optimal clearance. And I love the ease of fuel fill...

    What's my F3990 worth?

    Interesting, When I was trying to find information I ran across the Kubota dealer catalog which showed the Fxx80 series 2006 and 2008 product sheets and in those, the 3680 is 4WD only and only the smaller HP models in those years were available with an E suffix in 2WD only. Deere was similar...

    What's my F3990 worth?

    When I was looking at purchasing a F series last year, I learned that the majority are 4WD only. Kubota generally made the smallest model in the series available in 2WD only as an economy model but I don't think these are that popular given the relatively small cost and weight difference. I...

    Kubota F series

    When my Deere 955 was a few years old, I drove it out to start mowing and as soon as I engaged the PTO the engine bogged down. I drove it back to the barn to check the problem and a mud wasp had built a home around the vent on the fuel cap. Once removed the tractor was fine. Not sure whether...

    After spending around 10 hours for the last two days clearing up storm debris with my chainsaw and Deere 955 with loader, I finally had the chance to mow my 5 acre property for the first time with my new F 2690.

    Hay Dude, The only time I change deck height with my Deere 955 is when I raise it slightly for two tiny areas where the 72" deck would otherwise scalp. The lack of height adjustment ease with the F won't bother me because after 27 years with the Deere 955, I am very familiar with lack of...
