Gannon Box Blade Hydraulic Cylinder
Custom & Replacement Hydraulic Cylinders for Box Blade Applications
DALLAST manufactures custom and replacement hydraulic cylinders for Gannon box blades, box scrapers, grading attachments, and agricultural equipment.
Whether you need a direct-fit replacement for a worn or damaged cylinder, or an OEM manufacturing partner for custom box blade attachments, we build exactly to your technical drawings, physical samples, or specified mounting dimensions.
Hydraulic Cylinders Engineered for Box Blade & Scraper Attachments
A box blade hydraulic cylinder governs the continuous depth control, tilt, and angle positioning of the cutting edge during grading, soil conditioning, scarifying, leveling, and earthmoving.In replacement scenarios, dimensional interchangeability is non-negotiable. A variation in pin center-to-center distance, rod diameter, or pin diameter can lead to mechanical binding, misaligned blade geometry, or immediate seal failure under load.
DALLAST manufactures cylinders based on physical cylinder samples, CAD/technical drawings, or your field measurements-delivering an exact match for aftermarket repair, distributor inventories, and OEM equipment lines.

How to Measure Your Box Blade Cylinder for Replacement
Essential Parameters to Provide
Piston Rod Diameter (Dim B)
Measured on the polished chrome rod using a caliper.
Stroke Length (Dim C)
The total linear distance the rod travels from fully closed to fully open.
Retracted Length (Dim D)
Distance from pin center to pin center with the rod fully retracted.
Mounting Interface (Dims F & G):
Pin diameter and the inside gap of the clevis or outer width of the pin eye.
Operating Pressure & Thread (Dim H)
Operating pressure of your tractor hydraulic circuit (e.g., 2,500 psi / 170 bar) and port thread standard.

Built for Heavy Agricultural & Earthmoving Shock Loads
Box blades frequently encounter hidden tree roots, buried boulders, compacted clay, and sudden impact spikes that exceed normal operating loads. DALLAST box blade cylinders are engineered specifically to resist mechanical fatigue and hydraulic shock:
High-Tensile Honed Tubing: Precision-finished cold-drawn or DOM (Drawn-Over-Mandrel) steel tubing ensures seal longevity and prevents wall ballooning under instantaneous pressure surges.
Hard Chrome Plated Piston Rods: Induction-hardened and micro-finish chrome plated to prevent surface pitting, scratching from agricultural dust, and rod buckling under heavy compression loads.
Heavy-Duty Rod Wipers & Seals: Heavy-duty polyurethane exclusion wipers keep out abrasive grit, soil, mud, and water, protecting internal buffer rings and rod seals from contamination.
Reinforced Welded Construction: Deep-penetration automated welds on base caps and mounting clevises eliminate fatigue cracking caused by persistent implement vibration.
Quality Inspection & Pressure Testing Protocol
A dimensional match is meaningless if the cylinder fails under hydraulic load. Every individual cylinder manufactured by DALLAST undergoes strict testing prior to packing:
Dimensional Verification
Precision CMM and caliper checks verify pin-to-pin retracted length, pin hole clearances, and port alignments against the approved engineering drawing.
01
Full-Stroke Cycle Testing
Verification of smooth linear travel, checking for rod binding, concentricity errors, or abnormal internal friction.
02
Hydrostatic Pressure & Internal Bypass Test
Pressurized up to test standards (1.5x working pressure) to ensure zero internal piston bypass across seals.
03
External Leakage Inspection
Static hold under continuous pressure to verify rod seal integrity and zero port/weld porosity.
04
Anti-Corrosion Surface Finish Check
Paint adhesion and thickness verification to withstand outdoor agricultural storage and chemical exposure.

Hydraulic Cylinders for Box Blade & Scraper Applications
Gannon Box Blades
Custom and replacement hydraulic cylinders for Gannon box blades used in grading, leveling, backfilling, and ground preparation. Cylinders are manufactured to match your original stroke, pin-to-pin center distance, mounting dimensions, pin diameter, and hydraulic port connections.
Hydraulic Box Scrapers
Hydraulic cylinders for box scrapers provide precise control over blade elevation, cutting-edge angle, and scraper positioning during material spreading and surface leveling. Custom bore sizes, rod diameters, strokes, mounting styles, and port orientations are configured to match specific scraper designs.
