Product Description

The Ferris ISX 3300 60-Inch Zero-Turn Mower with Curtis Premium Air-Conditioned Cab combines Ferris’s commercial mowing platform with a climate-controlled Curtis enclosure designed specifically for compatible Vanguard-powered ISX 3300 machines.

At the center of Model 5902064 is a 40 HP Vanguard BIG BLOCK EFI ETC engine with Oil Guard, displacing 993cc from a two-cylinder configuration. Electronic fuel injection and Electronic Throttle Control are paired with Ferris’s commercial powertrain for demanding mowing applications.

Power reaches the rear wheels through dual commercial Hydro-Gear ZT-5400 Powertrain transaxles, each equipped with a 9-inch cooling fan. Ferris lists travel speeds from 0–12 MPH forward and 0–5 MPH reverse, giving the ISX 3300 the productivity expected from a large commercial zero-turn mower.

The mower uses Ferris’s ForeFront™ Suspension System, designed to isolate the chassis and operator platform from uneven terrain while keeping the cutting deck better connected to lawn contours. Ferris backs the suspension system with a separate 10-year suspension warranty under its applicable terms.

Cutting is handled by a 60-inch iCD™+ two-belt cutting deck with a published cutting-height range of 1.5 to 5 inches. Heavy-duty greaseable Hercules II cast-iron spindles support the commercial deck system.

The Model 5902064 also carries an 11-gallon fuel tank, 26 × 12-12 rear drive tires and 13 × 6.5-6 flat-free front caster tires. Ferris publishes a base-machine dry weight of 1,634 lb. for this exact Vanguard-powered 60-inch configuration.

For operator protection and climate control, this package adds the Curtis Premium A/C Cab SKU 1FISX33PR. Curtis explicitly lists Model 5902064 among the compatible Ferris ISX 3300 configurations.

The Curtis enclosure uses a lightweight aluminum structure with weather-tight perimeter sealing, tinted hard-coated scratch-resistant polycarbonate windshield and doors, and large rear-hinged lockable side doors. The doors can also be removed without tools when an open-cab configuration is preferred.

Its air-conditioning system is a genuine automotive-style A/C system using a mechanically driven compressor. Curtis supplies the system factory-charged, making it a purpose-designed climate system rather than a simple fan-based enclosure.
