EP-RC61T Lawn Mower Gearbox

EP-RC61T Lawn Mower Gearbox

With four selectable ratios (1:1 to 1:1.93) and 60 HP capacity, the EP-RC61T is designed for operators who run multiple implement types from one tractor. Custom harvesters and agri-service businesses reduce downtime and inventory by keeping a single EP-RC61T on hand instead of stocking four separate gearboxes.

โญ Fitur Utama & Keunggulan Teknik

⚖

Tip-Relief Quiet Gear Profile

Tooth profile modifications (tip relief + lead crowning) reduce gear-mesh noise by 6 dB versus standard straight bevel designs, improving operator comfort.

🚀

Abrasion-Resistant Cast Housing

Extra-thick grey iron walls with hardened mounting faces, resisting the abrasive wear caused by constant soil contact during deep tillage operations.

💪

Bolt-On Precision Flange Mount

Machined flange with dowel pin locations for accurate, repeatable tiller frame alignment, eliminating vibration-inducing misalignment during extended tillage runs.

⚙

Gear-Ground Tooth Flanks, Ra 0.5 ฮผm

Post-heat-treatment gear grinding achieves consistent surface finish and AGMA Class 9 geometry, reducing running-in wear and extending time to first service.

⚗

Hardened Dowel-Pin Alignment

Two precision ground dowel pins locate the housing halves within 0.02 mm, guaranteeing gear centre distance accuracy and eliminating assembly-induced backlash.

🔒

Zinc Flake Anti-Corrosion Fasteners

All external bolts finished with zinc-flake coating (Delta-Protekt) rated for 720 hours of salt spray, preventing seized fasteners during later disassembly.

🔄 Cross-Reference Compatibility for EP-RC61T

The EP-RC61T is engineered as a direct replacement or upgrade for gearboxes fitted to equipment from leading manufacturers including:

Bomford • Valtra • Yanmar • Lovol • New Holland • Bush Hog • Kioti • Vicon

๐Ÿ“š Panduan Pemilihan Transmisi

Choosing the right mower gearbox is critical for implement performance and longevity. Use the following criteria when evaluating the EP-RC61T:

๐Ÿ“Œ Menyesuaikan Rasio Gigi dengan Kecepatan Ujung Pisau
For the EP-RC61T with ratio(s) 1:1 / 1:1.21 / 1:1.46 / 1:1.93, calculate your required blade tip speed: typically 4,500-5,500 m/min for standard rotary cutters, 3,000-4,000 m/min for heavy brush cutting, and 5,500-6,500 m/min for fine finish mowing. Output RPM = PTO RPM รท ratio. Multiply by blade diameter to get tip speed.
๐Ÿ“Œ Penentuan Ukuran Daya yang Sesuai dengan Daya PTO Traktor
The EP-RC61T is rated at 60 HP. Always select a gearbox rated at or above your tractor’s maximum PTO horsepower. For shock-load applications (mulching, brush clearing), add a 25-30% safety margin: a 60 HP tractor should use a 75+ HP rated gearbox.
๐Ÿ“Œ Pilihan PTO 540 RPM vs 1000 RPM
The EP-RC61T operates at 540 rpm. Most rotary mowers use 540 RPM PTO. The 1000 RPM standard is for larger implements on high-HP tractors. Never connect a 540 RPM gearbox to a 1000 RPM PTO โ€” the doubled speed will destroy bearings and gears within minutes.
๐Ÿ“Œ Casing Besi Cor vs Casing Aluminium
The EP-RC61T uses a grey cast iron housing. Cast iron excels in vibration damping, impact resistance, and heat dissipation โ€” ideal for rough, rocky mowing conditions. Aluminium is lighter and more corrosion-resistant, better suited to wet environments and weight-sensitive implements.
๐Ÿ“Œ Katalog Standar vs Spesifikasi Khusus
The EP-RC61T is available as a standard catalog item shipping in 3-5 days. If your application requires a non-standard ratio, shaft type, or mounting configuration, our engineering team offers custom designs with 4-6 week lead times. Minimum order quantities may apply.

๐Ÿ›  Panduan Instalasi & Pengaturan

  1. Inspect the implement mounting pad for flatness using a straightedge. Any warping exceeding 0.5 mm should be corrected before the new gearbox is installed.
  2. Use Nord-Lock washers or thread-locking compound on all mounting bolts to prevent vibration-induced loosening during operation.
  3. Run the gearbox at no load for 5-10 minutes, then shut down and re-check oil level โ€” new seals and bearings often absorb a small amount of initial oil.
  4. Bersihkan permukaan tempat pemasangan alat secara menyeluruh, hilangkan semua karat, sisa material paking lama, serpihan cat, dan kotoran yang dapat menghalangi kontak yang rapat dengan flensa gearbox.
  5. Posisikan kotak roda gigi pada baut atau lubang pemasangan, pastikan poros input menghadap PTO traktor dan poros output sejajar dengan hub pisau atau rotor.
  6. Pastikan poros PTO memiliki tumpang tindih spline minimal 50% di semua posisi pengoperasian. Tumpang tindih yang tidak memadai menyebabkan keausan spline yang cepat dan potensi pemisahan poros.
  7. Catat tanggal pemasangan, pembacaan meter jam traktor, dan nomor seri gearbox dalam buku catatan perawatan Anda untuk keperluan garansi dan pelacakan interval servis.

โ“ Pertanyaan yang Sering Diajukan

โ“ Apa perbedaan antara pilihan rasio?

Rasio menentukan keseimbangan kecepatan/torsi pada output. Rasio 1:1 mempertahankan kecepatan PTO (RPM blade tinggi); rasio 1:1,93 hampir mengurangi kecepatan output menjadi setengahnya sementara torsi berlipat ganda. Pilih berdasarkan kecepatan ujung blade yang Anda targetkan dan kepadatan vegetasi.

โ“ Berapa lama waktu tunggu untuk model standar?

Model standar yang tersedia di stok akan dikirim dalam 3-5 hari kerja. Untuk model yang membutuhkan rasio atau konfigurasi khusus, waktu tunggu biasanya 4-6 minggu. Produksi cepat tersedia untuk kebutuhan mendesak.

❓ How do I select the right gear ratio?

Match the ratio to your blade tip speed target. Lower ratios (e.g. 1:1) give higher blade RPM for finish mowing; higher ratios (e.g. 1:1.93 or above) trade speed for torque, ideal for thick brush. Calculate: output RPM = input RPM รท ratio.

❓ What is the expected operational lifespan?

With proper maintenance, our gearboxes typically deliver 3,000 to 5,000 operating hours. Many units in the field have exceeded 6,000 hours. Lifespan depends on operating load, maintenance compliance, and field conditions.

❓ Is this suitable for mulching applications?

Yes. Our gearboxes are widely used on mulching mowers and brush cutters. For mulching, select a model rated 25-30% above your actual PTO horsepower to provide a safety margin against the intermittent shock loads typical of mulching.
