Husqvarna bars (.325″)
The Husqvarna 51 takes all Husqvarna guide bars with the Small mount, .325″ pitch and .050″ or .058″ gauge when fitted with a .325″ drive sprocket (default). The compatible original bars are listed in the two tables below. Recommended bar lengths are 13″ to 20″, compatible bars outside this range greyed out.
There are quite a few models, but in practice the narrow-kerf HLN-250 or XF-250 (X-Force) bars with a SP33G Pixel chain are the best match for the 3.1 hp power of the 51.

Husqvarna bars (3/8″)
Husqvarna 51 may optionally also be fitted with a 3/8″ pitch drive sprocket. In this configuration, the 51 takes Husqvarna bars with the Small mount, 3/8″ pitch and .050″ or .058″ gauge. These bars are listed in the two tables below; the too long 24″ models greyed out.
The inexpensive FT-280 (Farm Tough) or XF-280 (X-Force) models are the best choice for most applications. Prefer the replaceable-nose HT-280 and HT-288 models in intensive use and the hard-nose HA-280 in dirty conditions.

Oregon bars (.325″)
Oregon makes a large number of Husqvarna 51 -compatible guide bars in the K095 mount, .325″ pitch and both in .050″ and .058″ gauges. These bars are listed in the two tables below.
The narrow-kerf SpeedCut™ and AdvanceCut™ (MLB) bars (.050″) are probably the best choice for the power level of the 51.

Oregon bars (3/8″)
With a 3/8″ drive sprocket, Husqvarna 51 takes Oregon bars with the K095 mount, 3/8″ pitch and .050″ or .058″ gauge. These bars are listed in the two tables below, with longer-than-recommended models greyed out.
A quick selection guide: the AdvanceCut™ bars are light and affordable and the best choice for occasional use; the replaceable-nose PowerCut™ models will last the longest in intensive use.
