## Frequently asked questions

### What is the Husqvarna 450S Rancher designed for?

The Husqvarna 450S Rancher is a landowner chainsaw designed to tackle everything from forestry tasks like felling, cutting and limbing to cutting firewood. Its 50.2 cc engine produces 2.4 kW, or 3.2 hp, which is enough power for regular work on a property rather than the occasional garden prune.

### What bar length does the Husqvarna 450S Rancher take?

Husqvarna lists a recommended bar length of 50 cm for the 450S Rancher and a maximum of 50.8 cm, so there is almost no room above the standard setup. In practice the 450S Rancher is a 50 cm saw: trunks near that diameter are its ceiling, and anything thicker has to be cut from both sides.

### How much does the Husqvarna 450S Rancher weigh?

The Husqvarna 450S Rancher weighs 4.99 kg without bar and chain. That figure leaves out the 50 cm bar, the chain, the fuel and the 0.26 litre oil charge, so the saw as you carry it is noticeably heavier. At roughly 5 kg dry it is a two-handed ground-work saw, not a pruning tool.

### What chain does the Husqvarna 450S Rancher use and how fast does it run?

The Husqvarna 450S Rancher runs a 0.325 inch pitch chain at 18.51 m/s, with the engine idling at 2,800 rpm and topping out at 9,600 rpm. The narrower 0.325 inch pitch cuts more smoothly than a 3/8 inch chain, trading a little bite per tooth for steadier control on the 50 cm bar.

### How loud is the Husqvarna 450S Rancher and how much does it vibrate?

The Husqvarna 450S Rancher is rated at 106 dB(A) sound pressure at the operator's ear and 116 dB(A) sound power, so hearing protection is not optional. Vibration is low and evenly balanced at 3.9 m/s² on the front handle and 4.1 m/s² on the rear, which helps extend comfortable working time.

### What fuel and oil does the Husqvarna 450S Rancher need?

The Husqvarna 450S Rancher runs on petrol premixed with Husqvarna two-stroke oil, or an equivalent, at 50:1. Bar lubrication is separate and comes from a 0.26 litre oil tank. Husqvarna does not publish a fuel tank capacity for the 450S Rancher, so simply top the oil tank up at every refuelling stop.
