Befco Finish Mower Blade Part Numbers: Cross-Reference Guide

Thank you for reading this post, don't forget to subscribe!

⚡ Quick Answer

Befco’s current finish mower lineup is the C30 and C50 Cyclone series (not “C05/B05/T05” model names sometimes seen online — Befco actually uses “T” for its Till-Rite tillers, a completely different product). Each C30/C50 width has its own OEM blade part number, with low-lift, high-lift, and mulching variants available. Oregon also publishes a Befco-compatible blade (92-133) in its own catalog. Always match your exact model — including the H (solid tire) or A (pneumatic tire) suffix — before ordering.

Befco Finish Mower Models & Blade Kits

C30 Series

48″ (RD4), 60″ (RD5), 72″ (RD6) — each in H (solid tire) or A (pneumatic tire)

Blade part numbers: 0006795 (48″), 0006641 (60″), 0006845 (72″)

C50 Series

60″ (RD5), 72″ (RD6), 84″ (RD7) — each in H or A

Blade part numbers: 0006641 (60″), 0006845 (72″), 0006690 (84″)

⚠️ Key Point: Model numbers like “C05-060,” “B05-072,” or “T05-060” are not current official Befco designations — if you’ve seen these elsewhere, they don’t match Befco’s real lineup. Befco’s own current catalog uses C30 and C50 series names, and “T” is reserved for Befco’s Till-Rite tillers, not finish mowers. Always check your deck’s model tag against the C30/C50 tables above.

💡 Blade Variants: Each OEM number above also comes in low-lift (add “F” suffix), high-lift (add “B” suffix), and mulching (add “M” suffix) versions — for example, 0006641F, 0006641B, and 0006641M are all the 60″ blade in different lift profiles. Standard (no suffix) is correct for most general mowing use.

Aftermarket Option: Oregon 92-133

Oregon publishes blade 92-133 (24-9/16″ length) in its own catalog as compatible with Befco equipment. This is a genuine manufacturer-stated cross-reference, though Oregon’s listing doesn’t tie it to one specific Befco model number — measure your existing blade’s length before ordering to confirm it matches your deck.

How to Measure Befco Blades for Correct Replacement

📏 Blade Length

Measure tip to tip on a straight blade, not the curve. Measure the old blade before ordering — a bent or worn blade may read shorter than its true original length.

⭕ Center Hole Size

Measure center hole diameter precisely with calipers — wrong hole size means the blade won’t fit the spindle. Note any keyway slots.

📐 Width & Thickness

Record width and thickness before ordering. Thicker blades last longer in rough conditions but require more HP to spin.

Complete Blade Replacement Guide

Safety First

Disengage PTO and shut off tractor completely. Remove ignition key. Lower mower deck to ground on flat surface. Allow blades to stop completely — minimum 3 minutes after shutdown. Engage parking brake. Wear heavy leather gloves throughout — finish mower blades are sharp even when dull.

Access Blade Spindles

Tilt mower on its side or use ramps for underside access. Locate all spindle assemblies. Spray penetrating oil on all blade bolts — finish mower bolts corrode from grass moisture and debris. Wait 10-15 minutes. Use a wooden block between blade and spindle housing to prevent rotation during removal.

Remove Old Blades

Verify your model’s bolt size before starting. Turn counterclockwise to loosen. If stuck, use an impact wrench or breaker bar extension. Remove blade and inspect spindle for wear, cracks, or wobble — replace any damaged spindle before installing new blades, since a worn spindle destroys new blades quickly.

Install New Blades

Install with cutting edge facing correct rotation direction — check your operator’s manual for orientation. Install blade bolt with hardened washer. Apply anti-seize compound to threads. Torque to your model’s specification using a calibrated torque wrench. Verify blades are secure with no wobble, and confirm blade clearance from the deck housing.

Test & Verify

Lower deck carefully and verify no contact points. Start tractor and engage PTO at low RPM in an open area. Listen for unusual vibration or noise. Inspect cut quality on the first test pass. Re-torque blade bolts after the first 2 hours of operation, then check every 25 hours going forward. Also need Befco belts? See our Befco belt cross-reference guide.

Blade Troubleshooting Guide

Problem	Causes	Solutions
Uneven Cut / Leaving Strips	Dull blades, bent blade from impact, mismatched blade heights, worn spindle bearings	Sharpen or replace all blades as a set. Check each for bending. Verify all blades are the same length. Inspect spindle bearings for wobble.
Excessive Vibration	Bent blade, missing blade, unbalanced set, loose bolt, damaged spindle	Stop immediately. Inspect all blades for bending. Verify bolt torque. Check spindle for play. Balance blades before reinstalling.
Blades Dulling Quickly	Cutting height too low, sandy/abrasive soil, hidden rocks or debris	Raise cutting height. Walk field for large rocks before mowing. In sandy conditions expect shorter blade life.
Poor Grass Discharge	Dull blades, cutting height too low, mowing wet grass, ground speed too fast	Sharpen or replace blades. Avoid mowing wet grass when possible. Reduce ground speed in heavy growth. Clean underside of deck.

Seasonal Blade Maintenance

🌱 Spring

Inspect blades for winter rust, cracks, and bending. Sharpen to a 30-degree angle. Replace blade bolts annually. Check spindle bearings for roughness. Verify deck levelness side-to-side.

🔧 Every 25 Hours

Check blade bolt torque. Grease spindle zerks. Inspect blades for new bends or chips. Clean deck underside. Check belt condition and tension.

⚙️ Every 50 Hours or When Dull

Sharpen and balance blades. Inspect spindle condition and seals. Check for looseness in deck hardware. Verify PTO shaft CV joints are greased.

❄️ End of Season

Remove and sharpen blades before storage. Grease spindles to prevent rust. Clean the deck underside thoroughly. Note any needed repairs for next season.

❓ Frequently Asked Questions

How often should I replace Befco finish mower blades?

Replace when the cutting edge is rounded and won’t sharpen further, the blade shows visible bending, cracks appear anywhere, or cut quality drops despite a sharp edge. Under normal conditions, expect roughly 1-2 seasons per blade set with proper sharpening; rocky or sandy conditions shorten that. Always replace all blades on a deck as a complete set — mixing worn and new blades causes vibration and uneven cutting.

What are the current Befco finish mower model names?

Befco’s current finish/grooming mower lineup is the C30 and C50 Cyclone series, sold in various widths with H (solid tire) or A (pneumatic tire) suffixes — for example, C30-RD5H or C50-RD6A. If you’ve seen model names like “C05,” “B05,” or “T05” referenced elsewhere, those aren’t Befco’s current official designations — “T” specifically refers to Befco’s Till-Rite tiller line, a different product entirely. Check your deck’s model tag directly against the C30/C50 naming pattern.

What causes Befco finish mower blades to bend?

Hidden rocks or debris in the field, cutting height set too low (increasing ground-contact risk on uneven terrain), mowing over irrigation heads or buried obstacles, or hitting fence posts and field borders at speed. A bent blade cannot be safely straightened — the metal’s structure is compromised at the bend point and will fail under stress. Replace it immediately; continuing to operate with a bent blade causes vibration that destroys spindle bearings within hours.

How do I know which Befco blade fits my model?

Check your deck’s model tag against the C30/C50 tables above to find your correct blade OEM number. If the tag is worn or missing, measure your existing blade’s length, center hole diameter, width, and thickness, and match those to the confirmed OEM parts listed here. Keep your old blade as a reference when ordering, since getting it wrong wastes both time and return shipping.
