UDC Parts AM137327 Side Discharge Mower Blades Replacement for John Deere 42 Inch AM141034 D105 D130 D110 S100 EZtrak Z235 Z225 M154061 AM141032 E130 E120 D100 D125 E110 LA125 LA115 / 2 Pack High lift

What It Is

This is a 2-pack of high-lift side discharge mower blades designed to replace OEM John Deere blades on 42-inch cutting decks. High-lift blades create stronger airflow to eject clippings out the side chute and improve bagging performance, making them ideal for decks that struggle with wet or thick grass.

Fitment & Compatibility

Deck size must be exactly 42 inches – measure your deck width, not the tractor model. These blades are direct replacements for OEM John Deere part numbers AM141034, AM141032, M154061, and AM137327. They fit the following John Deere models: D100, D105, D110, D125, D130, D140, E100, E110, E120, E130, LA115, LA125, Z225, Z235, Z245, Z255 (EZtrak series). Do not assume compatibility based on tractor model alone – verify your deck’s blade length and center hole size (these are 21 inches long with a 1-inch diameter center hole). Check your current blade for a part number stamp.

Key Things to Know

• High-lift blades increase power draw – you may notice slightly reduced engine RPM or fuel efficiency, especially in thick grass. Not ideal for underpowered or older tractors.
• Installation is straightforward but requires a torque wrench (recommended 40-50 ft-lbs) and a blade removal tool or block of wood to prevent rotation. Always disconnect the spark plug first.
• Sharpen before first use – factory edges are often dull. A file or bench grinder will improve cutting performance immediately.
• Balance is critical – after sharpening, check blade balance on a balancer. Unbalanced blades cause vibration and damage the spindle bearings.

Should You Buy It

Buy this if you own one of the listed John Deere 42-inch deck models and need a budget-friendly, high-quality replacement for bagging or side discharge. It’s a solid value for the price and rating, but skip it if your deck is smaller or you prefer standard (non-high-lift) blades for mulching or low-power tractors.
