Engine Oil Filters

Engine Oil Filters for John Deere, Kawasaki, Briggs & Stratton & More — OEM & Agrif Replacement

Agrif carries a complete range of engine oil filters for lawn tractors, compact utility tractors, zero-turn mowers, riding mowers, skid steers, and compact track loaders. The collection includes genuine John Deere Original Equipment filters (AM125424, M806419, RE519626) and Agrif aftermarket 2-pack replacements for the same applications — cross-referenced to over 150 OEM part numbers across 12+ equipment brands including Kawasaki, Briggs & Stratton, Kubota, Hustler, Toro, Bobcat, Husqvarna, and Craftsman.

Genuine OEM vs. Agrif Replacement — What's the Difference?

Every product in this collection is available in two formats. Genuine John Deere Original Equipment filters are manufactured to OEM factory specifications — the same filter that shipped with your machine, with guaranteed fit and John Deere-backed quality. Agrif  replacement filters are 100% new aftermarket filters manufactured to meet OEM quality specifications and cross-referenced to identical thread sizes, bypass valve pressure ratings, and micron specifications — at a lower per-filter cost and with two service intervals per order.

Both options are stocked, shipped free, and backed by a 30-day return policy. If you are a professional turf manager or fleet operator, Agrif 2-packs also include a 1-year warranty on the RE519626 application — covering a full planting and harvesting season.

99% Filtration Efficiency — Built to Protect Your Engine

Agrif oil filters are engineered to capture 99% of engine oil impurities — dirt, metal particles, combustion by-products, and wear debris that accumulate in lawn tractor, compact tractor, and zero-turn mower engines between service intervals. Independent testing confirms that running a high-efficiency filter at every service interval reduces internal engine wear and extends engine service life by up to 30% compared to under-filtering or over-extending service intervals.

Each filter incorporates dual-layer filter media construction with high-temperature resistance — essential for small-displacement engines that run hot under sustained mowing loads. A knurled, non-slip outer canister surface makes hand-tightening and removal clean and confident without a filter wrench in most applications.

Anti-Drain-Back Valve — Cold-Start Protection Every Time

Every filter in this collection includes an anti-drain-back valve (ADBV) that retains oil in the filter housing after engine shutdown. For seasonal lawn equipment that sits between uses — weekday tractors, weekend riders, spring-to-fall mowers — this valve ensures that oil pressure reaches bearings, camshafts, and valve trains within milliseconds of the next cold start, rather than after a damaging dry-start interval. The bypass relief valve (rated at 8–11 PSI for residential applications and 30 PSID for the RE519626 diesel engine series) opens under cold-start conditions or when the filter media reaches capacity, maintaining uninterrupted oil flow in all operating conditions.

How Often Should I Change My Lawn Tractor Oil Filter?

Service intervals vary by engine manufacturer and application. As a general guide: AM125424 applications (residential lawn tractors, Kawasaki-powered zero-turns) — every 100 hours or annually, whichever comes first. M806419 applications (compact utility tractors, commercial turf) — every 150 hours. RE519626 applications (utility tractors, skid steers, diesel engines) — per engine manufacturer recommendation, typically every 200–250 hours or one agricultural season. Always consult your machine's operator's manual for the precise interval that applies to your engine and operating conditions.
