Yato YT-85552 Lawn Tractor Blade, Left-Hand Side
Genuine spare part for the Yato YT-85552 garden tractor, part code YT-861940. A cutting blade for fitting on the left-hand side of the mower deck, made of iron and measuring 535 x 85 x 35 mm.
Features of the lawn tractor blade
Left-hand fitment only
This blade is designed for fitting on the left-hand side of the mower deck only. Tractors with two blades require the correct configuration — the left and right blades have a different cutting geometry, which ensures even shredding of the grass and the correct discharge direction.
535 mm working dimensions
A blade length of 535 mm and a width of 85 mm provide the right cutting reach within the mower deck. These parameters must match the original dimensions — an overly long blade may collide with the housing, while one that is too short will leave uncut patches of lawn.
Iron construction
The part is made of iron, which after heat treatment provides suitable hardness at the cutting edge while retaining a flexible core. This construction minimises the risk of cracking on contact with hard objects in the grass.
Genuine Yato part
The code YT-861940 denotes a genuine manufacturer's spare part. This ensures that the mounting holes, material thickness and blade balance match — parameters that are critical for safe operation at the 2,500-3,000 rpm typical of garden tractors.

Applications of the lawn tractor blade
- Replacing a worn left-hand blade on the Yato YT-85552 tractor
- Restoring cutting performance when the cutting edges have become blunt
- Repair after mechanical damage to the blade (contact with a stone or root)
- Mowing domestic lawns of up to 2,000 m²
- Maintaining green areas on recreational plots
- Care of small parks and urban public gardens
- Seasonal maintenance of the tractor ahead of intensive use
Compatibility check
Before buying, check the model of your tractor (rating plate or owner's manual) and the mounting side. On the Yato YT-85552 with two blades, the left-hand blade is fitted on the driver's side. The part code YT-861940 must match the manufacturer's catalogue for the model year of the machine.
Blade maintenance and replacement
A tractor blade needs replacing after 50-80 hours of mowing, or as soon as there are signs of blunting, nicks or cracks. Symptoms of wear include uneven cutting, ragged tips of the grass (which turn brown after mowing) and increased vibration of the mower deck.
Fitting a new blade requires disconnecting the spark plug (to prevent accidental starting), tilting the tractor onto its side and undoing the mounting bolt with a socket spanner. The tightening torque for the new blade should be 40-60 Nm — if the fixing is too loose it will cause vibration, while over-tightening may damage the thread in the spindle.
After fitting, check that the blade rotates freely (with no contact with the housing) and is balanced — uneven wear or an incorrect blade weight places excessive load on the spindle bearings and shortens the service life of the transmission.
Sharpening tractor blades
Tractor blades can be sharpened 3-5 times before they need replacing. Sharpening is carried out with an angle grinder at an angle of 30-45 degrees, keeping the original profile of the edge. Material must be removed evenly from both ends of the blade to maintain balance — a weight difference of more than 3 grams between the ends causes vibration at high speeds.
