Yamaha Terrapro Specs and Review 2022

Yamaha Terrapro: The Yamaha Terrapro: is one of the most valuable inventions from the 1980s. 

Unknown to many, this utility quad pioneered the lineup of belt-driven and differential-equipped vehicles we enjoy today. 

Yamaha Terrapro

The mower could be taken off and transformed into an enjoyable, leisure ATV. On workdays, attachments can make the Terrapro back into a utilitarian vehicle to manage large grasses or young plants.

Produced between 1987 and 1988 The Yamaha Terrapro is remembered as the very first and only ATV with the power-take-off (PTO) features. 

It was equipped with a 350cc 4-stroke engine and a hydrostatic transmission as well as a locking rear differential, this quad proved way ahead in its day.

Similar to the Big Wheel 350, Yamaha invented its Terrapro with the best intentions but it was released at the wrong time 30 years too early. 

If it was made in the later years with liquid cooling and 20 horsepower power output the Terrapro would have been a blazer 500-class ATVs thanks to its wide use. However, even with its basic technology and fan-cooling, this riding mower is still regarded as the top machine of its kind.

Yamaha Terrapro

Among Yamaha’s First

The Yamaha Terrapro was 10th in the line of Yamaha off-roaders since the US launch of the Tri-Moto and sixth in the series of four-wheelers manufactured in the 1980s prior to The 1988 Consent Decree fully sealed the ATC ban. 

The Terrapro was sandwiched between the ’87 Big Bear 350 and ’88 Blaster The Terrapro is the first quad to have the power take-off feature. This unique feature allowed the driver to utilize the wide range of Yamaha Terrapro attachments. 

Some of them included rough-/finish-cut lawn tillers, mowers, agriculture sprayers, diggers for post holes, and many more.

Although many people remember the legendary Terrapro for its flexibility, however, what made the Terrapro distinctive was the fact that it was Yamaha’s original utility vehicle. 

The design and the mechanism could be the model of the modern-day Ultramatic V-belt transmission as well as an LS differential. The main reason why this model doesn’t seem to be a hit to many off-roaders is the fact that it was a single-year model. 

Its time on the ATV scene was so brief that people were not aware of the vehicle in certain parts of the US and in other countries. This not only impacted the popularity of the vehicle but also created an issue.

Customer Impressions

Although Yamaha Terrapro parts are pricier and claim that the process of operating the unit is a nightmare numerous enthusiastic supporters and fans confirm and affirm the safety that the quad has. 

The young riders of the 1990s were taught how to cut their lawns with this beast of a quad. Owners claim that they have only replaced the clutch cable, brake pads, and the fuel cutoff valve after buying it new in 1987. 

As with all off-road beasts, the Terrapro is reliable and can last for many years when properly maintained and cared for.

  • Drivetrain It is a 5-speed manual hydrostatic transmission with sub-low and high 2WD. It comes with an electronic throttle that can be controlled by thumb, levers that control the gas (like the gas valve on a tractor), as well as the kill switch, which is activated solely when PTO is in use.
  • PTO operates on belts and, depending on the type of attachment, it may need an RT-38 or FM-48 B-15, RC-42, or a version. It also comes with an inner differential lock on the rear which prevents the machine from breaking grass. The lock for the differential is on the left and appears to be on the same stage as the choke that is activated by its ignition button.

There are a few sources that offer complete specifications and information about maintenance on the Yamaha Terrapro for free. 

The results of a search will not contain the dimensions of the entire vehicle. If you have this quad, you should purchase a Yamaha Terrapro Service Manual (view on Amazon). It’s useful for troubleshooting in the first place and ordering repair kits and replacement parts for your quad.

Prices and Expectations for Terrapro

Nada Guides only shows retail prices (and is not what the manufacturer’s suggested retail price is) of the Terrapro Between $375 and $2,700. Auction listings put this classic machine at between $180 and $2,735. 

In general, a Terrapro in good operating condition will have an operating transmission that has hi, Lo, and PTO speeds, as well as accessories such as the seed spreader or brush hog. Sellers typically declare attachments (if there are any). 

Some of the most commonly used is that of FM-48 Mowing Deck (SN: 2035) and the RT-38 Roto-Tiller (SN: 408).

You can expect the ATV to have seen minor repairs to its home and may have broken knobs, worn grips bent cargo carriers, or seat cover that has been ripped, and broken or crusted footpegs. Be prepared to spend an extra few dollars because some of these used vehicles might require hydraulic maintenance. 

Rings from the stock may need to be replaced too. But this shouldn’t be an issue, as rings from any 350cc ATV will work as long that the bore-stroke ratio is in line. It’s not often that you can find an ATV like a Terrapro with glossy plastics and a non-rusting frame and under 1,000 hours.

Yamaha Terrapro Problems

Since the car is nearly 33 years old, it’s normal for owners to encounter a few problems. However, its one-year production, the difficulty of obtaining replacement parts, the difficulty of finding the right Terrapro-certified mechanics and dealers, and the comprehensiveness of the service manual make attempting to resolve the problems complicated – for a novice rider, at the minimum.

Because there are many who are not expert off-roaders, I’ve provided the following some of the most important Terrapro issues that can assist the novice owner:

Differential Locking Not Locking

The most obvious sign of this issue is when the lever switch isn’t functioning properly, and is and the wheels are going at a constant speed. The lever switch can be removed and then resetting it should do the trick. 

Yamaha Terrapro Specs and Review

It’s pretty easy when you know what you are looking for. However, understanding the process in case you’ve never used that lever switch before will be the difficult part.

The difficulty of shifting to reverse

If you completely press the foot brake using all of your weight and then push back the lever will not drop enough or click. It could also be that the clutch does not operate reverse or it may not be disengaged. If these issues occur you should check the spring-pulled cable that is coming out of the brake pedal on the rear, and trace it to the shifter. 

In the majority of cases, there will be a cylindrical end of the cable retracting bent. It happens frequently because the cylinder is prone to get stuck to the housing’s lip, which stops it from moving. 

If this doesn’t appear to be the cause it may be due to the vehicle being left idle for too long.

Rear Brakes Aren’t Working

The most typical reason that your rear brakes don’t function is if they’re bone dry. To remedy this you must apply the correct brake fluid and then flush the brakes. Following these steps will reveal the presence of leaks within your sealed brake system. 

If the first two steps don’t work then you may require adjusting the brakes in order to bring them back within the limits when you add fluid.

Rough Shifting

A few owners struggle with the shifting of the Terrapro. The cable sometimes rips which causes uneven shifting. If you notice this happening you can pull the shift cable free of the casing, and then try the lever to determine whether it can move easily. 

If it does, it could suggest that the issue is related to your cable and shifter. A new cable can fix the issue. A lot of PTO, clutch or throttle cable is up for sale on reseller websites such as eBay or Amazon.

Doesn’t Run in High

There are a variety of scenarios in which your quad might not be able to run at a high speed, for example:

  1. When PTO is in use
  2. With the differential secured
  3. Towing tools

To solve this issue, you must look beyond these scenarios requires you to pinpoint the issue. It usually is traced back to an electrical issue such as an electrical safety cutoff or fuel supply that is not sufficient, or a malfunctioning switch (located close to the two-point hitch located on the back). 

If the problem is an inoperable switch, it could be removed and then shorted by using spade connectors.

Another area worth considering is the speedometer since it comes with an electric reed switch which transmits a signal to the CDI to prevent over-revving of the engine. If that reed switch isn’t functioning and the CDI will incorrectly assume it is still, and it will stop immediately at speeds higher. 

It is possible to test a reed switch by a speedometer’s rotation. In the same way, and implemented safety switch can stop the PTO from activating if there is nothing is connected. Moving the governor throttle forward with no towing device could also cause engine damage.

To bypass switch on safety in Terrapro is among the many methods that have been tested to solve the issue with the vehicle running high temperatures.
