![]() As the blade rotates when cutting grass, the bolt moves to the right, fastening the blade tightly to the driveshaft. Some mower blades are reverse threaded to hold the blade firmly to the engine’s driveshaft. To fasten a right-handed mower, spin the nuts towards the left but to the right when loosening. Right-handed mower blades move towards the left when mowing. Use the pitching direction to determine if your mower blade bolts are right-handed. Their threads wrap around the shaft from the bottom, pitching upwards to the right. Reverse threading is also called left-hand threading, which shows the threads pitching towards the left direction.įasten reverse threaded mowers by rotating the bolts towards the right but to the left when loosening.Īpart from reverse threading, most machines or equipment fasteners such as screws, bolts, or nuts are right-hand threaded, meaning they turn clockwise when screwing in. Observing this direction will help you determine if your mower blade bolts are reverse threaded or not. ![]() Threads, defined as the continuous spiral ridges on the bolt, move from the bottom, pitching towards the left in reverse threads. Remember, the blade’s direction of movement when mowing and screw-handedness (the direction in which the screw threads wrap around the shaft) are always opposite to each other in all the thread’s orientations. Blades of a reverse threaded mower appear to turn to the right if observed from the mower’s top while mowing. Reverse threading is a fastening method where threads in the retaining bolts wrap around the shaft counterclockwise. It’s vital to know your mower blade bolt’s direction of rotation to unscrew the bolts or fix the blade effortlessly. Continuous fastening adds more safety as the rotating bolt holds the blade tightly, otherwise, it can injure the person operating it. Lawn mowers operate by rotating the blade beneath to cut the grass. Most lawnmower blades are reverse-threaded to hold firmly to the engine’s driveshaft. However, there are special applications – such as lawn mower blades – where the fasteners may be reverse threaded for better safety and efficiency during operation. This negative level cannot be overcome in any way (including by restoration spells) while the sword is wielded.Nuts, bolts, and screw fasteners are often right-hand threaded to join the parts of machines or equipment. The negative level remains as long as the sword is in hand and disappears when the sword is no longer wielded. All sun Blades are of good alignment, and any evil creature attempting to wield one gains one negative level. When the wielder stops swinging the sword, the radiance fades to a dim glow that persists for another minute before disappearing entirely. The radiance begins shining in a 10-foot radius around the sword wielder and extends outward at 5 feet per round for 10 rounds thereafter, to create a globe of light with a 60-foot radius. The sun Blade then sheds a bright yellow radiance that acts like bright light and affects creatures susceptible to light as if it were natural sunlight. Once per day, the wielder can swing the Blade vigorously above his head while speaking a command word. The Blade also has a special sunlight power. Against Negative Energy Plane creatures or undead creatures, the sword deals double damage (and ×3 on a critical hit instead of the usual ×2). Against evil creatures, its enhancement bonus is +4. In normal combat, the glowing golden Blade of the weapon is equal to a +2 bastard sword. Likewise, Weapon Focus and Weapon Specialization in short sword and bastard sword apply equally, but the benefits of those feats do not stack. Any individual able to use either a bastard sword or a short sword with proficiency is proficient in the use of a sun Blade. In other words, the weapon appears to all viewers to be a bastard sword, and deals bastard sword damage, but the wielder feels and reacts as if the weapon were a short sword. However, a sun Blade is wielded as if it were a short sword with respect to weight and ease of use. This sword is the size of a bastard sword. Aura moderate evocation CL 10th Weight 2 lbs.
