... which are common in the Agri-Business and Equipment Parts Industry. It is designed to help visitors and customers come to understand our products and the benefits to them.

• Cummins.  

Cummins Inc. is an American multinational corporation that designs, manufactures, and distributes engines, filtration, and power generation products. It is known for its line of diesel engines agricultural and commercial. Wikipedia

Cummins specializes in diesel and alternative fuel engines and generators, and related components and technology. Learn more at cummins.com

• IVECO.

IVECO, an acronym for Industrial Vehicles Corporation, is an Italian multinational transport vehicle manufacturing company. It designs and builds light, medium, and heavy commercial vehicles. Many farmgrit.com parts sold on our site have "Cummins/IVECO" in the product name.

The name IVECO first appeared in 1975 after a merger of Italian, French, and German brands.^[1] Its production plants are in Europe, China, Russia, Australia and Latin America and it has about 5,000 sales and service outlets in over 160 countries. The worldwide output of the company amounts to around 150,000 commercial vehicles with a turnover of about €10 billion.^[2]

The company was spun-off from CNH Industrial on 1 January 2022. It is subsidiary of Iveco Group N.V., a holding company incorporated in Amsterdam, Netherlands, and is listed on Borsa Italiana.

• PTO - Power take-offs.

PTO - A power take-off is one of several methods for taking power from a power source.

A power source such as a running engine, transmitting to an application such as an attached farm implement. FarmGrit PTO - Power take-off parts cover the widest range of PTO needs for farmers using all makes and models of equipment.

• Transmissions.  (Informational)

Farmgrit.com provides transmissions, parts and assemblies of all types for all brands of tractors, combines and powered farming equipment.

A gear-drive transmission is designed to lock a tractor into one speed.

It is well-suited for rough terrain and sloping. 

A gear transmission is an affordable option.  Plus, it allows for maximum PTO performance. 

Here are the four different gear-drive variants available on compact tractors:   

1. Collar shift.  Uses a fork and collar between each set of gears.  The collar gear transmission is a bit expensive.  The trade-off is increased reliability.

2. Power shift.  This transmission uses a clutch pack instead of collars.  There is no need for a clutch.  Shifting is effortless and seamless. You simply push a button or move a lever to shift up or down.

3. Synchro shift.  Similar to the collar shift --- with the addition of a synchronizer.  The synchronizer acts as a brake or drag to “synchronize” the speeds between the gears when shifting.  This prevents grinding and gives a quieter, smoother shift. 

4. Sliding gear.  Uses a shift fork to put gears into position.  This is a lower cost option.

A gear-drive transmission is best-suited for an experienced operator.  It is not the easiest option to use, requiring vast practice.  Another disadvantage is the lack of precise speed control that a hydrostatic transmission can provide.

A power shuttle transmission combines electronic controls with hydraulic clutch packs.

This provides a clutch-less option to engage the transmission for repetitive reverse and forward maneuvering.

Power shuttle offers the power, reliability, and strength of a mechanical transmission without involving your feet, legs, and hands.

They are perfect for applications including drawbars and loaders.

A power shuttle transmission is a bit more expensive than a shuttle or standard mechanical transmission.

Hydrostatic Transmission 

The hydrostatic transmission is the most popular on compact tractors.

It is easy to use and provides a smooth ride. 

They are great for inexperienced/novice operators or those who do not understand manual transmissions. Hydrostatics operate like automatic transmissions in cars.    

This transmission is efficient, smooth, and easy to operate.  They are optimal for loader work and any task where the implement does not require it to be maintained at a constant speed.

Speed control is another advantage.  Operators will experience precise speed control.  They also will be able to utilize cruise control. Plus, there are both electronic and mechanical options.

The hydrostatic transmission uses hydraulic fluid to power the axles and drive gears.

Electronic hydrostatic provides many premium features to maximize your tractor performance.  There are some tractor models that use this technology to allow features including stall guard, hydraulic dual speed, throttle up, and more, so you can get maximum power for heavy duty applications.

CVT Transmission     

A continuously variable transmission “CVT,” offers operators a mix of a hydrostatic and mechanical transmission.

With a CVT, you can seamlessly shift through the ranges by pressing down on the handle or pedal, without ever having to shift ranges.

The CVT combines the durability and power of a mechanical transmission with the smooth, easy operability of a hydrostatic transmission.

There are many benefits to a CVT.  This includes longer transmission life, ease of use, and better fuel efficiency.

A CVT is a great option; just difficult to find on a smaller tractor.  It has great features but not common on a smaller tractor or small utility.  This is mainly due to cost.  They come at a premium price compared to the hydrostatic option.  Hydrostatic is easier to use and far more affordable.
