20hp V twin Cylinder Vertical Shaft Ride on Lawn Mower Engine Replaces Briggs

20hp Twin Cylinder Vertical Shaft Ride on Lawn Mower Engine Replace Briggs

There are a few things to check before purchasing this engine:

Does your engine have a Briggs & Stratton bolt pattern? Our engine does. You can view the bolt pattern in the thumbnail pictures to check if it matches up with the engine you are replacing. If it doesn’t match you can always drill new holes in your deck.
Does the engine you are replacing have a 25.4mm shaft?
Will our engine fit into the same space as the one you are replacing? Check the dimensions of our engine in the thumbnail listings, just to make sure.

These engines are absolutely top of the range.
They are sold with a one year warranty and all spare parts are available and in stock.

Please contact us if you have any questions.

The bolt holes on this engine will require thread tapping. If you are switching from a single cylinder to a v-twin you may need to drill new bolt holes in the chassis.

Please note: this is an universal fitment engine and some modifications to the mower might be needed. You will also need to thread tap the mounting bolt holes at M10 x 1.5.

This engine also requires a seperate choke and throttle cable. A combined choke/throttle cable will not suit. Please act accordingly.

Features:

Twin shaft balance system to reduce the vibration of the engine
Angled fan blades designed to reduce noise while maintaining appropriate air flow
Dedicated full flow fine oil filter for superior lubrication
Cast iron cylinder formed with centrifugul casting
Crankcase with built in balanced ventilation system to avoid external seal leakage and reduce oil consumption

WARRANTY OVERVIEW

Jono & Johno offers a 12-month warranty on most products.

We pride ourselves on selling good quality gear and will be fair and prompt in honouring our warranties. If you’re in trouble, we’ll help you out.

WHAT IS COVERED?

The exact warranty coverage depends on two factors:

Whether the fault is due to user error or a manufacturer defect
Whether the fault is minor or major

Minor faults caused by the user

Parts will be supplied for repair at the user's expense.

Minor faults caused by the manufacturer

Customers are expected to perform basic repairs as part of our warranty process.
Jono & Johno will provide replacement parts and instructions for simple repairs, such as installing a recoil starter.
Jono & Johno will determine whether a fault is classified as minor.
If unsure about a repair, contact us, and we’ll assist you.

Major faults caused by the manufacturer

Jono & Johno will arrange a return, refund, or replacement at our expense.
If preferred (and at our discretion), we may provide replacement parts and contribute to labour costs if you can perform the repair.

Major faults caused by the user

Where possible, parts will be supplied at the user's expense.
If the item cannot be repaired by the user, we offer repairs at our workshop at $80 AUD per hour.
The customer will need to cover return shipping costs for user-related faults.

RETURN PROCESS & SHIPPING COSTS

If you need to return your product:

In-store return: If you're near a Jono & Johno outlet, you can return the product in person. Contact us first to arrange a return authority.
Shipping return: If you are not within driving distance, we will provide a return address.

EXCEPTIONS TO THE RULE

Some products are not covered by warranty, including:

Engines used in go-karts and stump grinders

OUT-OF-WARRANTY PRODUCTS
