Husqvarna 455 Rancher 55.5-cc 2-cycle 20-in Gas Chainsaw

Choosing this product

Choosing the 455 Rancher for your wood-cutting workload

The Husqvarna 455 Rancher listing for model 970613240 identifies a 55.5-cc, two-cycle gas chainsaw with a 20-inch bar. Consider it in the context of the wood-cutting work you expect to do over a season. Write down the typical material, how often you will work and the experience of the person who will use the saw.

Engine displacement and bar length help compare models, while handling, maintenance and the nature of each job determine whether a particular saw belongs in your routine.

Distinguish ordinary firewood preparation from work involving unstable trees, overhead hazards or nearby structures. A more powerful engine does not remove the need to assess those conditions or arrange professional help. When comparing this Rancher with a smaller battery saw, include the requirements of owning and storing a fuel-powered tool in the decision.

When comparing it with another gas saw, consider the complete working setup rather than choosing solely by the longest advertised bar. Ask to identify the actual saw and installed cutting equipment before building an accessory list around a general series name.

Planning the project

Comparing handling features and cutting-equipment fit

The 455 Rancher's LowVib system and Air Injection system address different ownership considerations. LowVib uses vibration isolation to improve handling comfort, while Air Injection separates larger debris before it reaches the air filter. Compare them as distinct features: one relates to what the operator experiences and the other to the engine's intake system. Neither is a substitute for the protective equipment, breaks, inspections and maintenance specified by Husqvarna.

Consider the saw with the equipment you will actually use, including its fitted bar and chain.

Replacement-chain shopping needs more information than the words 455 Rancher or 20 inches. Husqvarna manuals show multiple approved cutting-equipment combinations for the series, with different pitches, gauges and drive-link counts. Record the markings on the installed bar and confirm the matching chain and drive configuration through the manual or a Husqvarna servicing dealer. Keep the full product number and serial number in the same record.

This is particularly useful when comparing a listed saw with a later catalog version: the shared Rancher name does not prove that every cutting component is identical.

Installation and everyday care

Planning fuel, lubrication and scheduled service

Set aside time for the maintenance schedule in the Husqvarna operator's manual before choosing a gas saw for recurring work. The schedule covers the cutting equipment, safety devices, air intake and other checks at different intervals. Air Injection reduces the larger debris reaching the filter, but filter inspection and cleaning still belong in that schedule.

Keep records of service and replacement parts so a future technician can distinguish ordinary wear from an unidentified change in configuration.

The two-cycle engine's fuel requirements and the bar-and-chain lubrication system are separate subjects in the manual. Use the approved product instructions for both, including transport and storage, instead of treating an oil specification in a retailer table as a universal instruction. Read the correct operator's manual for the saw's market and serial range before use. Husqvarna's support page provides manuals and a route to parts assistance.

A qualified servicing dealer is also a useful resource when fitted parts, starting behavior or safety-device condition cannot be established from the approved owner checks.

Product and compatibility questions

Does every 20-inch chain fit this 455 Rancher?

No. Nominal bar length is only one part of compatibility. Chain pitch, gauge, drive-link count and the fitted cutting-system configuration must agree. Use the markings on the saw's actual bar with the appropriate Husqvarna manual or dealer guidance. Do not copy a replacement-chain specification from a different 455 Rancher listing without checking the complete product number and installed equipment.

Ordering and maintenance questions

Do LowVib and Air Injection eliminate maintenance?

No. LowVib addresses vibration transmitted through the saw, and Air Injection helps keep larger particles away from the air filter. The operator's manual still sets out inspection and maintenance tasks for the filter, chain, lubrication and safety devices. Treat these features as points to compare when choosing a saw, while planning for the full care schedule throughout ownership.
