REVIEW: Yamaha U-Max "Light Duty" UTV

The new Yamaha U-Max was delivered yesterday after lunch. I purchased the unit as a 'people hauler' and to move some light materials, garden supplies, shooting supplies, etc. but not for heavy hauling, towing, etc.

At $4505, including sales tax and delivery, this is on the bottom of the scale for side by side units in terms of price, features or performance.

For people who want to "run the trails" this is NOT the unit for you. For people who are used to operating golf carts and looking for a people hauler that can also take a modest amount of cargo, this is a nice unit.

It should be noted that the U-Max is a 2 wheel drive unit. Something that I had to explain to my daughter and will have to explain to my wife. It goes up the hills on my property with no problems, but it "free runs" down the hills and you end up riding the brakes in th curves as you descend the slope through the woods. I have 3 main paths on the hills to go from the upper to the lower property. The U-Max is not allowed on 1 of those, PERIOD. Then again, I've never even descended that particular slope in my 4wd tractors. The second slope drops off a low spot along a roadway and is roughly a 15 foot vertical drop. The U-Max easily climbs that slope but going down the same slope is a free running thrill ride that terminates into a cluster of Hawthorn trees. I can manage it, but I won't let my 12 year old daughter attempt it. The third path is the long way around, winds through the woods and is far more gentle, no problem up or down.

One other thing about the U-Max is that it operates LIKE A GOLF CART. You turn the key to the ON position and nothing happens. However, touch the accelerator pedal and the engine starts instantly. Take your foot off the accelerator and the engine completely shuts offs. There is no way to let the engine "idle" while the unit is parked.

It should also be noted that this is a "commercial grade" product, designed for landscapers, ground crews, and marketed to them. That means it is pretty much a bare bones design, spartan but functional. It is also pretty small; roughly 4' wide by 8' long.

Here are 2 photos from the manufacturer, I'll post my photos later, along with some more of my review.

Good review of the U-Max Bob. It looks like just what you were after.
I'm guessing you could upgrade the tires if you need more aggressive tread for your grassy hills. I've ridden in golf carts with tires like that. If the grass is wet going down hill can be an experience, they can lose traction and spin ...maybe you won't see that until the tires are worn down some.... But I figured it was worth mentioning.
The U-Max looks like fun. I bet you get plenty of use out of it.
 
I've got a few minutes before an appointment so I'll give a little more detail. The tires are semi-knobby turf tires and seem to have pretty good grip on the slopes, I spun them a little only while climbing and only right at the edge of the roadway I was climb up onto when they hit a bit of gravel on the road's edge. So far they are good enough. And 'good enough' probably describes this unit very appropriately.

It is not good enough for hunting or trail riding. It is good enough for people transport on most normal terrain. It is not good enough for heavy work, but it is good enough to haul the guns out to the shooting range, or the garden tools out to a remote spot on the property, or pool supplies down to the pool area.

The dump bed is a manually activated bed. It is a dual wall heavy thermoplastic one piece bed with provisions for turning it into a "stake bed" cargo box. Using 1x4 lumber uprights you can easily attach a home made rail system to increase the hight of 3 sides of the dump box. The rear, however, is a curved upward slope and has no provisions for a rear set of rails to be added. The curve is a nice feature for dumping because it does allow for a clean and smooth dump of material that is in the small cargo box. And the cargo box is pretty small. Just about 45" wide and just under 30" front to rear. There are also 2 drain holes in the cargo box to allow water to easily drain out. Despite the fact that the cargo box is a plastic material, it is very tough. I compared it to the metal cargo box on the no-name UTV sold at Tractor Supply and while the no-name brand had a bigger box, it was very lightly built in comparison.

The next model up U-MAX uses a larger dump box on a longer wheelbase chassis. That model also has an electro hydraulic assist dump cylinder and the box also has a locking flip down tailgate instead of the curved rear on my light duty model.

I'm thinking of mounting a gun rack on the front hood of the U-Max to allow for carry of rifles and/or shovels. Conversely, I may use the stake bed pockets on the rear for some sort of a carry for tools.

In the various photos you can see the similarities to a golf cart. Although when it was parked next to golf carts at the dealership it has more ground clearance and more aggressive tires, but a SHORTER wheelbase and LOA, yet it still shares a lot of heritage with golf carts. The steering wheel is identical to a golf cart's steering wheel, even has a place for a score card and a pencil. The operators controls are also identical to a golf cart. One thing it does have, that is making me crazy, is a back up alarm that sounds a shrill noise when shifted into reverse. And I can't find the damn thing to disconnect it!!! :smileywac

The suspension of the U-Max is slightly heavier duty than the very similar golf carts. Its a very basic machine with a heavy tube steel frame, decent clearance and more than enough speed for my fairly rough ground. It has a top speed of 15mph as it is delivered, but the dealer showed me a simple change that will remove the governed speed limiter and up the top speed to 25mph. I've not done that yet, and probably won't change it for a while, my daughter loves speed and I'm not sure I want to give her the extra 10mph!

I am thinking of buying the roof and frame (looks like a ROPS but is not as sturdy). Not because I really want a top, but mainly so I have some place to attach a rifle rack for carrying long handle tools, weed wackers, and rifles.

It goes up the hills on my property with no problems, but it "free runs" down the hills and you end up riding the brakes in th curves as you descend the slope through the woods.

That looks perfect for an around the house people mover and homeowner yard cart. On freewheeling down hills; it should stop freewheeling if you press on the gas pedal. I know that sounds counter intuitive, but try it once (at a safe location obviously) and see if it actually slows. Designs may have changed in the last 30 years, but I'd imagine the drive system is a Salisbury clutch type of system. With those designs, they will freewheel down hills if you don't touch the gas pedal and cause the centripetal cogs in the clutch to engage. They are governed by the engine speed and not the wheel speed.
 
Brent, thanks for the tip. I wondered about that, but as you said it is counterintuitive.

I'm pretty happy with it so far. I'm sure I'll find days when I wish I had something bigger/heavier duty/higher capacity. But I'm sure that those days will be reasonably rare. I don't pretend to think this is a workhorse like a large John Deere Gator or Kubota RTV, but then at less than 1/2 the price and dimensionally smaller, it is what it is. I would say it compares very favorably to the John Deere COMPACT Gators. Those are in the same class as this, but they had true turf tires and what appeared to be less clearance.
 
Heavy rains = soft ground. Our land is clay, so it tends to pack the tractor tires if things get really bad. It was NOT that bad, but the round was soft to walk on out at the range. BUT there was not even a hint that the U-Max had any problems!!!

In fact, it seemed to have a little better traction??? The U-Max, with me, a handgun, cleaning supplies and 350 rounds of 9mm ammunition weigh less than 1000# total weight. The big 20" semi-knobby tires barely left an imprint on the bare ground in between the rows of soybeans.

I REALLY LIKE THIS THING!!!


I also found out, based on a test recommended by Dargo :thumb: that if you accelerate the engine SLIGHTLY while going down the hill it will actually slow the rate of decent and make it easier to control on the downslope. It is very counter-intutitive, but it worked! THANKS BRENT!!! :applause:

Honestly I have no regrets about not buying a bigger, heavier, 4wd unit. This thing fits the bill perfectly for my desires, and the fact that it is idiot proof makes it something that even I can master :tiphat:
 
One thing it does have, that is making me crazy, is a back up alarm that sounds a shrill noise when shifted into reverse. And I can't find the damn thing to disconnect it!!! :smileywac

Bob, get on your knees behind the vehicle with your head down near the rear bumper. Have your daughter back up while you listen for the source of the BEEP BEEP SPLAT! :poke:
 
The warning buzzer is somewhere in the front. I thought I found it, but it turned out that I found the HORN. One of these days I'll get really sick of it, put it up on the car lift and play underneath it until either the buzzer is dead or I am.
 
There is a kit available from Buggies Unlimited that will allow my EZGo to idle rather than shut off when you take your foot off the gas peddle. I'm sure something similar is available for your Yamaha. This would help in the down hill sections.

The reverse "squealer" is an integral part of the ignition system on my cart. If you disconnect it or bypass it, the ignition won't fire. I trimmed down an earplug and stuck it into the small hole on the unit. It's almost silent now. Just enough noise to know that it's in reverse when you park it. (It won't shut off with the ignition switch.)

From the look of it and your description, yours seems to be the exact same as my EZGo, basically a grounds keeper's vehicle.

Does your unit have front brakes? (Hydraulic?) Mine are cable only, on the rear only. There's a reason for the 15 mph gov.
 
Looks like your EZ-Go would be about the equivalent of the "Medium Duty" U-Max as your unit has a larger dump bed than my "Light Duty" U-Max.
