Swisher OEM Hydraulic Pumps | Horsepower 20-35 HP | For Zero-Turn Mowers & Tractor
Â
DESCRIPTION
Power your Swisher commercial equipment with genuine OEM hydraulic pumps engineered for reliable, high-performance operation in demanding professional applications. This premium collection features three heavy-duty hydraulic pumps designed to deliver consistent flow rates from 16 to 22 gallons per minute, providing the hydraulic pressure needed to drive wheel motors, implement lifts, and auxiliary hydraulic systems on zero-turn mowers, commercial lawn equipment, and hydraulic-driven machinery.
The 16 GPM Hydraulic Pump (Model LS2002B - Part# 1003437) represents Swisher's premium hydraulic solution for commercial-grade equipment requiring robust, sustained hydraulic flow. This precision-engineered pump delivers 16 gallons per minute of hydraulic fluid circulation, providing the consistent pressure needed to power dual wheel motors on zero-turn mowers and heavy-duty riding equipment. Built to OEM specifications, this pump ensures perfect compatibility with Swisher's hydraulic drive systems while delivering the reliability that commercial landscapers and grounds maintenance professionals demand. The LS2002B handles continuous operation in high-heat environments, maintaining stable pressure output even during extended mowing sessions on large properties.
The 16 GPM Clockwise Rotation Pump (Model 17094) offers directional-specific hydraulic power for equipment requiring clockwise shaft rotation. This versatile pump matches the 16 GPM output of the LS2002B while providing the specific rotational direction needed for certain Swisher equipment configurations. The clockwise rotation design ensures proper hydraulic fluid flow through the system, preventing cavitation and maintaining optimal pressure to wheel motors and hydraulic implements. This pump is essential for maintaining manufacturer-specified performance on equipment designed for clockwise hydraulic pump operation.
The 22 GPM High-Flow Hydraulic Pump (Model 19166) delivers maximum hydraulic performance for larger commercial equipment and high-demand applications. With a nominal flow rate of 22 gallons per minute operating at 3600 RPM, this pump provides 37.5% more hydraulic capacity than standard 16 GPM units. The advanced dual-displacement design features low-pressure output of 16.22 ml/r and high-pressure output of 7.04 ml/r, allowing the pump to efficiently adapt to varying load conditions. The preset relief pressure of 4.5 MPa and working pressure of 21 MPa ensure safe operation while delivering maximum power when needed. This high-capacity pump is ideal for larger zero-turn mowers, commercial-grade riding equipment, and applications requiring auxiliary hydraulic power for implements like mower deck lifts, baggers, or hydraulic steering systems.
All three pumps feature precision-machined components that minimize internal leakage and maximize volumetric efficiency, ensuring every drop of hydraulic fluid contributes to usable power. The robust construction withstands high operating temperatures, contaminated hydraulic fluid, and the shock loads common in commercial mowing applications. Sealed bearing assemblies protect internal components from moisture and debris, while hardened drive shafts resist wear from constant high-speed rotation.
These hydraulic pumps are designed for equipment powered by 20-35 horsepower engines, with the 16 GPM models suited for 20-28 HP applications and the 22 GPM high-flow pump optimal for 28-35 HP power units. Proper engine horsepower is critical—undersized engines cannot maintain the RPM needed for consistent pump output, while these pumps ensure engines in the proper range deliver full hydraulic potential to drive systems.
Power Requirements: 16 GPM pumps require minimum 20-28 HP engines to maintain 3600 RPM under load. The 22 GPM high-flow pump requires 28-35 HP for optimal performance. Compatible with PTO-driven and engine-direct hydraulic systems on zero-turn mowers, commercial riding mowers, and hydraulic-drive lawn tractors.

I've started using the mulcher I on several parcels of land 10 acres . I have grind down a couple of 14 inch stumps. Caution the mount bracket behind the mulcher motor exhaust gets extremely hot even with gloves on . But the unit so far seems to works very good it's well put together.
The Firminator G3 is s heavy duty quality machine. The discs worked extremely well and planting and culti-packing is very smooth and easy. Working with Dillon at Ripping It Outdoors was a very good experience and seamless transaction.
The week before leaving for my mule deer hunt in Wyoming, I seeded the area surrounding the new runway at Wertheimer Airport in Norman.
This past Tuesday, I returned to finish the job and was pleased to see that the seed I planted just two weeks earlier was already germinating and coming up nicely.
These pictures show the freshly seeded areas alongside those planted two weeks ago. It’s a great comparison and a good example of what proper seedbed preparation and planting can accomplish.
I used my Ferminator G-3, which is one impressive piece of equipment. It prepares the seedbed, plants the seed, smooths the soil, and firms everything up for good seed-to-soil contact—all in one efficient operation.
I’ve owned and operated several no-till drills over the years, but I can say without hesitation that the Ferminator is the most efficient and versatile seeding machine I’ve ever owned.
There’s something pretty satisfying about returning to a job and seeing those first green shoots coming through the ground. That’s when you know your hard work is paying off!
Just got my Buffalo Turbine! Love it. Took a little bit to get used to getting the right angle for the nozzle, but not a problem. Side note, works much better if the frame is level as much as possible.
Love it!

Seems to be in order delivery wasn't able to use lift gate but tractor was able to take pallet off the truck bed. No damage to machine after visual check. won't know how it runs until rain stops.
Staff at RippingitOutdoors was very quick to call and double check the type of backet needed for the unit to ensure the online order matched( to fit my skid steer quick attachment on my l2501 Kubota). Explained the teeth & belt could be ordered through them directly over the phone when/if needed as well as selling other types of custom made brackets for Utv's ect. All around Great customer service and would purchase from again.
After spending way to much money for forest mulching services I discovered this wonderful machine. It's not a giant powerhouse forest mulcher, but it does everything a property owner needs to maintain a forested property. I wish I would have found it sooner.
The Firminator is well built and functions well. I am having some trouble while planting mixed size seeds. Next time out I’ll try setting it so only the smaller seeds drop out the open it up for the larger seeds.
easy buying process and great communication. Mulcher works great, easily clears overgrown brush and even mulched a 5" thick mulberry tree fairly easily. running it off of my old 331 bobcat with no problem powering the drum at all. Only small issue which isn't a big deal is that the supplied hoses are about 16" too short to operate a full range of motion.
Over all built well. I like it is all cast iron and metal and not plastic. Had to modify fertilizer disc mount to fit correctly, nothing major, a little grinding. I modified the center link hitch point to accommodate my John Deere quick hitch. Have yet to plant with it but I’m sure it will work perfect. Love the grease fittings everywhere. Reminds me of the old farm equipment I grew up on, and still use periodically.
My firminator RT was delivered in good condition in ND. I will be using it next week. I have a 45 HP John Deere tractor that is supposed to lift 2000 lb but really struggles to lift this 6 foot firminator RT. I will just have to use in as a two pass operation for now.
I do wish there was a better operating manual for this unit. Maybe that is something you can work on.
I will give you an update once I start using it in a few days.
Great piece of equipment. Performs far better than I expected. One piece of advice - if property is significantly overgrown, consider the tractor attachment first to bring down the over growth and then switch to the UTV attachment to maintain property. No complaints worked perfectly.
seeds come out way to fast at lowest setting when planting alfalfa literally the only reason I bought it now I can't even use it and I can't return it so I'm stuck with it for the price you pay you would think it would work!
It’s built solid. It handles Field grass hip high pretty well. With the maintaining the field grass after the first cut, the pasture field is starting to look like a lawn. The 84 inch with the best thing to get for 8 acres. It’s best to order belts for back up in the event if the belts were to break. But overall, I like the product quality is good.
When I think of ripping it outdoors something else comes to mind, but I digress. This spreader is awesome. Works like a champ. The hopper is big enough to do my 1 acre lot for my applications. Just load once and go. I would highly recommend this spreader. It saves a ton of time and is a quality product.
