Kubota G1800 Parts – New and Aftermarket

Kubota G1800 Parts

The Kubota G1800 is one of the G series of Kubota mowers, first manufactured in the late 1980s, and was kept in production until approximately 2000.

It was and still is a highly popular garden tractor, that came as either a two wheel or a four-wheel steer.

There are still a significant number of these mowers in use, and there are a wide variety of parts that are needed in order to maintain a safe and efficient operation.

Kubota G1800 parts can be obtained online, or though a network of tractor dealerships.

The Kubota G1800 is well known for its high levels of performance, its manoeuvrability, the fact it can be used all year round, its compact design and its ability to be engaged in a variety of demanding tasks

It has a fuel capacity of 5 gallons, a wheelbase of 50 inches and weighs approximately 700 – 750 pounds.

The Kubota G1800 comes with either a 48 inch mid mount mower deck, or a 54 inch mid mount mower deck.

Safety is key to the G1800, and obtaining and fitting the correct parts is a crucial element in maintaining its longevity as a machine, and it safe usage whenever it is in operation.

When looking for parts, it is often a good idea to try and obtain a copy of a pdf manual as well.

When buying parts for the Kubota G1800, it is a good idea if possible to have the chassis number of the machine, as well as being able to be as specific as possible as to which part is actually required.

This will help to track the part, and also help in locating a manual if needed which will contain diagrams for Kubota G1800 parts, and greatly help in being able to fit them properly.

Kubota G1800 Parts

Replacement parts for the Kubota G1800 may be needed at any point in its lifetime, either as replacement parts in a routine service, because a part has become defective or simply because of old age !

Parts can normally be obtained either from Kubota itself, or from a third party supplier.

Replacement parts made by another manufacturer are normally referred to as aftermarket parts. Aftermarket parts should perform the same function as a standard manufacturer part, but will normally be cheaper.

If the Kubota G1800 is still under warranty, then it is likely to be part of the warranty conditions that manufacturer parts are used. A number of people also prefer manufacturer parts because there are specifically designed to be used with the appropriate tractor.

Below is a breakdown of the main areas and categories of parts used in most Kubota tractors and agricultural machinery. It is really important to check the specific item needed prior to purchase, especially if bought online

Parts category

Batteries

Kubota batteries use the most current technology to make sure there are sufficient and powerful as possible. These normally include a negative plate paste expander, and a sodium sulphate additive.

Belts

Kubota mower belts are claimed to last up to 3 times longer than comparable aftermarket products.

In addition, they are made in what is called an alignment line, allowing the courts to equalise the energy distribution flow. This results in a more stable tension. In addition, they contain fiber enforced rubber that helps support the integrity of the belt

Kubota G1800 Filters

Engine oil filters

An oil filter is meant to help reduce or eliminate any potentially damaging element may be produced by the engine oil to date the activity

Hydraulic filters

A Kubota hydraulic filter is designed to do a similar job to an engine oil filter, but the hydraulic system, thereby protecting valves and hydrostatic transmission parts, which are an integral part of keeping the tractor operating safely and efficiently

Other types of filters include a suction filter, an HST filter, a fuel filter and an outer air filter.
