Our Kubota RTV900

The hill we grow our organic edible cactus on is very steep. This makes it a good spot for the cactus as the south-facing hillside means none of the plants are shaded by the others around them. The soil is good for the plants, and the cold air drifts down the hillside and away from the plants. But while this prime location is good for the plants, the steep hillside makes for extreme challenges in maintenance. We needed a vehicle that could get up the hillside safely transporting stone and soil and cactus.

I looked at several Utility vehicles and ATV’s to find one that would work for our particular circumstances.  Our uses for a vehicle in this spot are extreme and very focused in intent and use….. we need to have a dump bed-box behind so that I can easily dump loads of rocks, soil or waste cactus without having to dismount on the steep hillside…. we had to have four wheel-drive as two wheels would not have the traction needed on the steep scree slopes. We needed to have Roll-Over Protection System (ROPS, AKA Roll-Bar), for more safety we wanted to have engine braking so that the vehicle is slowed by the engine when coming downhill…., and we wanted durability and longevity (I prefer not having to work on equipment a lot).

I went to a number of websites and read comments about the various brands available…. and while many people extol one brand/model over another, most people agree that the expectations and uses of the unit determine the relative performance in various uses. For instance, if you want to go fast the PolarisBobcat, and JohnDeere brands have several models that are greatly favored by hunters and off-road enthusiasts. I also really liked the idea of the all-electric Huntve. Most of these vehicles can reach speeds of 40 MPH, most are gasoline engines with excellent throttle-response and four-wheel drive capabilities. some also offer electric lifts on the bed to dump items. But it seems none of them have all of the things I was looking for….. and with our steep narrow paths, it’s doubtful I’d be going over 5 mph very often….

In the end it is the Kubota RTV 900 that we chose.  It does not go fast, it’s slow getting up hills, it is based on tractor technology with a unique hydrostatic transmission that gives the engine-braking that increases my safety greatly on this steep ground. And I can haul a thousand pounds of rock, back it into a small spot and dump it without having to leave the seat when on a narrow terrace.

The Kubota RTV900 also has hydraulic Quick-Disconnects (QD’s) that can be easily opened and a hydraulic-powered tool added in, to run on the hydraulic system…… for me I can see the use of a hydraulic-powered two-person hand-held auger (for drillling into the ground for posts), a pole-chainsaw, and a hydraulic jackhammer being some tools I might occasionally rent for a day or three of use.

There are a few things that one should know about this machine, and some of them are listed on the complaints that others have posted about it…. one is that the transmission is designed to slow and even stop the vehicle when throttle is reduced….. some people complain this will nearly “pitch you out the windshield”… personally, I like that feature…. if I get scared about a steep spot I am in, I can take my foot off the throttle and the vehicle stops. Also when going steeply downhill with 500 lbs of waste cactus I can stay in low-range and not have to keep my foot riding forcefully on the brakes… the engine itself will keep the engine speed low… in fact, I have to keep my foot on the throttle to even continue going downhill for very long. Another great feature of this transmission’s braking feature is the fact that if I decide to stop going downhill and come to a stop, I can then shift into reverse and reverse direction without a heart-stopping slide downhill while applying throttle… the machine will stay in place until I give enough throttle to overcome the engine-braking feature and it will then continue back uphill. The sense of control with this machine is excellent.
Another item often mentioned as a problem is the sticky shifting, and lack of shifting while in motion. Like many tractors this one does not allow shifting while in movement…. you might start in low-range to get out from the shed, then stop and shift into high range to drive to the work-site, then again down into low or medium-range to move around the work-site. No shifting on-the-fly here…. if you’re going off-road into terrain that calls for frequent shifting, you’ll find yourself stymied by the constant stops to shift into another range. If you are travelling with friends with more conventional ATVs and UTVs, you’ll find yourself behind the pack most of the time while the fast responsive machines whiz by on the road, and fly past you on jumps. This machine is not one built for sport… it is built for work. Another shifting issue often mentioned is sticky shifting, especially into low-range and into reverse. I’ve found this is not really a real ‘issue’ once you learn two things…. one, have the wheels facing straight ahead.. this relieves pressure from the system and allows things to unbind better… two, if you cannot shift easily, ‘blip’ the throttle once or twice, this will allow the shifter to engage, even when the wheels are turned. Ive found shifting from 4WD to 2WD or the other  is a bit challenging if the wheels are not straight, I often find I have to drive foward (or back) for a dozen feet in order to stop and shift into/out of 4WD… for some folks this might be a real problem…. but since I automatically shift into 4WD before I need it, it’s not a real issue for me.
Two items I’ve not seen listed as a detraction are the location of the key-switch on the console and the location of the parking brake by the open doorway. The key-switch location and the small cab for my size (6’4″ 250 lbs) have resulted in my left knee turning off the engine several times when turning in my seat to look behind me as I back into narrow steep spaces….. and at times I am leaving the cab on a steep slope downhill on the left…. I have to take extra care that I do not accidentally smack myself against the parking brake which is located alongside the doorway opening on the left…. I’d hate to accidentally disengage the brake while dismounting. I am sure the engine braking on the shut-off engine would help prevent a runaway vehicle…. but as I grow more comfortable with it, I’ll be testing the safety on slopes in various modes of operation.

Again, any vehicle, is designed to perform certain functions, and some functions cannot be retained in order to more narrowly focus use. I agree that most people might well be better-off with one of the other UTV vehicles….. but for us the Kubota RTV900 fits our uses better than anything else I’ve seen or driven. I’m VERY happy with our machine and have been using it nearly daily hauling much heavy dirt, rocks and waste cactus. It’s been stable with a  low center-of-gravity, a tractor-y low-end torque which feels very strong, and the handling is similar when filled with 750 lbs of rocks as when the large and strong bed is empty.
Another factor in our choice was our satisfaction with our old Kubota tractor we got nearly 20 years ago from a contractor friend who wanted a newer stronger model Kubota. So this old machine had a lot of use before we got it, and it still runs fine. So I like the experience I have had with Kubota in the past.

The video above is a Kubota video that shows what I consider to be the best aspect of this vehicle.. the engine braking transmission and the 900 cc diesel engine. Keep in mind the video is a commercial by Kubota… so I find it amusing to watch the overacting of one fellow driving the John Deere Gator.

 

The video below is from the Polaris company… they are comparing one of their machines to the Kubota RTV900.

Like the Kubota com-video, this one extoles the virtues of their machine in ways that refelct positively on their product. Yet I cannot disagree with anything they say…. the Kubota has no real storage area in the cab (but I’m not likely to be far from anything I need), no tie-downs in the bed (which I’d just bang up with rocks), little cab-room (but longer would reduce my turning radius), lower wheelbase (and perhaps lower COG?), runs on diesel (but I’m happier with the low-end torque of a diesel), smaller fuel tank (but diesel gives you more hours of operation per gallon), and the Kubota is not nearly as good at higher speeds, or extremely boulder-y terrain.
In short, if you are going to go off-roading, away from home, hunting, or wanting to take jumps, mudholes etc, you are better off with the Polaris or John Deere. The Kubota is heavy, massive and strong and built for slow steady work, not sport.

Low-Rider Truck in Pismo Beach

I came upon this Low-Rider truck in the Pismo Beach/Grover Beach area….
It is nicely detailed and efficiently engineered.
It can lower itself until the body unit rests on the ground.

Drive it till the wheels fall off

1972 Ford Pinto

I saw this car at the Post Office… the fellow driving it said he got it from his mother after she passed away a couple of years ago. She’d had it since it was brand new, and she kept it in a garage. The whole 38 years she had it she drove it a few times a week to go to church and the store and visiting folks, but she never left Santa Barbara with it.  When he got it.. it had only 60,000 miles on it, and it still has the orginal factory paint!  He just uses it to drive around Nipomo… but he says it runs great….

Hot Cars

I was going down 101 and saw a bunch of Hot-Rod and antique cars parked on the side of the road resting. I just had to stop because it was too good an opportunity to see these machines close up. They were headed to a car show, and happily I knew a couple of the fellows in the group.. so they let me take photos and publish them.

 

Guinea Hen on a bumper

   This is our neighbor’s Guinea Hen.  It likes the sheltered area that this bumper gives… solar radiation is concentrated here by all the black paint…. it is sheltered from the breeze…. a good spot for a bird.

  Guinea Hens are very interesting birds…. I think they are a bit smarter than your average fowl.
   This one likes cars and often runs alongside our car when we go to visit the neighbor’s.
   It runs alongside Vickie’s car… sometimes in front of her bumper…. its head almost level with the bottom of her window….
   They make a screeching sound that a lot of people find annoying.  As far as I know, people don’t raise them for meat or eggs….. they mainly have a reputation of being an ‘easy-to-have bird’… they don’t really need to be caged… anyone we’ve known that had Guineas just let them roam free. They tend to find the place they want to live, and hang out there, eating the bugs all around… they are also very vocal, and when someone comes onto the area, they will sound an alarm…. it’s hard to sneak up onto a house with Guineas, Dogs, or Geese.  These birds used to live at another place up the hill… but they wandered and became friends with ‘Little Man’ the pony and lived with him in his pony run. Since they had no fear of cars, and would try to chase people away… one got run over by a car and died. Now there is just this one Guinea left.. and Little Man.

Summertime is for travel

Trike

 

  Yep, this looks like fun.
  I wonder if I could get one with a small bed that would hold a few hundred pounds of cactus in boxes?

  On the other hand… this looks like a lot of fun also! And I could carry a lot of cactus in the back of that wagon.  the long spring travel on that beast might smooth the ruts of our dirt road out pretty nicely.

   It’s summertime now… the freeway is crowded with motor homes, Subarus with luggage on top, antique automobiles cruising… and motorcycles

   Yeah… it’s all good.

Drifting Accident

Drifting Accident on dirt road

   There’s plenty of misconceptions about any group of people anywhere. Outside folks will have their ideas, which are usually re-inforced by Hollywood films (Hollywood is so cliche.. but that’s part of the fun of it all).

   In most Hollywood films, country-folks living on dirt roads tend to drive really fast… sliding around corners on the dirt and gravel…. tires leaving the earth as saddles are topped…. in actuality, such driving will get you dirty looks from most folks you’ll encounter on those roads…. if you go out of control you’re going to run into their fences or trees, or other vehicles on the road.

   Regardless of how much fun it is to slide around blind curves… it is not something you should do… and driving fast on a  dirt road raises huge ripples that will cause costly damage to any vehicle that uses them regularly.

  We have hardly anyone living back in this canyon…. yet we still see several vehicles go into the creek each year. And this particular fence gets whacked every so often also… it is at the end of a straight-away that is really fun to slide around…. but here we see three recent impacts… two of them that still bear fresh tire marks.   Your right to drive like a lunatic ends where my fenders begin.

  Don’t drive like ‘The dukes of Hazard’ in our canyon!

Expensive way to save money

   Saving money is good… everyone has some things they can do themselves and save a bit of money. When it comes to cars… the best way to save money is buy one you can work on yourself…. also having a model that does not have a ‘cachet-name’ with it helps…. one of the brands that is a good vehicle… but seems to have higher associated repair costs is Lexus…. We have one… which sounds really cool and affluent until we mention that it is 20 years old, and has about 235,000 miles on it …. and some 40,000 of those miles are on our dirt road.   A dirt road is not a place to take a ‘luxury car’…. and while I used to be a half-way capable ‘wrench’, these new cars with their computers, smog-control equipment, front-wheel-drive, and other exotic components mystify me. On the other hand, these cars don’t need all the maintenance that the older cars need. ‘Back-in-the-day’, I used to change my oil every three thousand miles…. I would pull my plugs out every-other oil change… and clean and regap the points…. and then I would have to reset the timing….. once you’ve done this a number of times on your vehicle… it’s not such a big deal. But with these newer cars the computer takes care of the ignition process…. and the new breeds of spark plugs with their exotic alloys typically last for years.  But gone are the days of me packing my own bearings….. or changing shocks…. I don’t really understand how all drive-train/suspension components operate… and the parts are VERY pricey.   We bought the Lexus because I ran our truck into a deer and totalled our truck out. The neighbors were selling their Lexus, and Vickie had driven it several times and liked it a lot.  They gave us a good price since cars are hard to sell here due to our remote location.  Oh yes, it’s a nice car… once you get onto the highway…. it cruises down the road very comfortably… luxuriantly even.  But a rutted dirt road is not a good environment for a luxury car… which our mechanic tells us often when we go in for routine suspension-component replacements.

   A few weeks ago we noticed the car had a tiny bit of a miss…. and the idle speed was ranging up and down. So I decided to take off a big hose that leads from the air-filter to the injection manifold. There is a little flap in there that controls the amount of airflow…. this little flap can gather bits of material on it which will impede the airflow, and cause problems with idle speed. As I took the hose off I noticed the hose itself, surely twenty years old, and being in a hot engine compartment for nearly a quarter million miles was hard and had cracked. This was allowing some air into the system after some of the smog-control equipment measures the airflow… this gives erroneous readings to the computer which fouls everything up. So it should be a simple task to replace an air-hose.

010610LexusAir2

This is the old torn hose.  The right end is where it hooks to the engine…. the little connection-point in the middle is where air-flow/vacuum measurements are taken by the computer…. since the break was after that point it messed with the computer’s data… causing uneven idling.

010610LexusAir3

   Here is the replacement hose… and this is where the story really starts….
   This is not one of those common hoses you can pick up at a discount Auto-Parts store…. no, this is specially molded for Lexus….  I told Vickie that a hose like this should be maybe $30 to $40…. but I was worried since it is a Lexus it would probably be $70… LOL.

   It was $135 after I paid the California State extortion-tax of over 7%. Yeah, $135 for a molded hose…. and that’s just the hose…. Installation would probably be another hundred or more dollars.

   010610LexusAir4

   This is the hose installed onto the engine…. it took maybe 15 minutes for us to replace the hose and clean the valve in the intake.

010610LexusAir5  010610LexusAir6

   While we had the hose off, it was easy to access the air filter. Air filters should be cleaned regularly, especially if you are on dirt roads….
   You can take a dirty air filter and bang it on a hard surface to knock off most of the dust…. make sure you knock the correct side off (the side where the air flows through)… and don’t allow dust onto the clean (engine) side.  Usually after a couple of cleanings, I replace the filter. This one is not too bad off, we knocked it off to show the dust that can accumulate, but I replaced it with an extra I had bought on sale last year… two-for-one. 

   The old data about a dirty air filter using more gas is not quite so accurate anymore… the computer systems on newer cars will detect a clogged filter and adjust the air/fuel mix accordingly… so you won’t be running rich like in the old days. But since you have less air/fuel mix going in, you’ll lose power, acceleration and response.  So it’s still worthwhile to keep your filters open and passing plenty of clean air for the engine.

010610LexusAir7

   While we had the filter out we vacuumed the filter housing… there will be big things that dropped off the filter in there… might as well get rid of them. You can see how dusty the engine compartment is… dirt roads are not the place to drive luxury cars… trucks and Subaru’s are the best bet for our roads.

   At any rate… the hose replacement worked… after firing it up, the engine roamed up and down for a few moments… then the idle settled down to a stable speed and the miss is gone…. it really is a nice (if dusty) car out on the highway.
