Baumalight 3P38-S1050 Valve Kit
Authorized Baumalight Dealer
Ensuring quality backed by full manufacturer warranty & support.
The Baumalight 3P38-S1050 Valve Kit (part number: S1050) is an optional external hydraulic control system purpose-built for use with the Baumalight 3P38 three-point hitch PTO stump grinder. The 3P38 is designed for tractors with a 540 RPM PTO and a high-horsepower range of 60–110 HP — a class of tractor that frequently comes equipped with only a single set of hydraulic remotes despite the extra power on offer. Running the 3P38 at full capacity requires control over both the swing and lift cylinders, which normally demands two remote circuits. The S1050 solves this directly by providing a dedicated external valve unit that takes over hydraulic management, allowing the operator to run both functions from a single tractor remote without any tractor-side modifications.
Beyond resolving remote limitations, the S1050 significantly improves the quality of the grinding operation itself. The control is mounted on an adjustable arm, and the built-in flow control allows the cutting pass speed to be fine-tuned to match the tractor's size and output — delivering the smoothest possible cut and, with a full return to start position, the quickest overall stump grinding cycle time. This level of feathering control through the external valve is more responsive and intuitive than working the hydraulics directly through the tractor's levers, especially for operators tackling tough or irregular stumps where sweep speed matters. The 3P38's rugged gearbox delivers 1,475 ft-lbs of torque at 810 RPM, and having precise sweep control via the S1050 ensures that power is applied efficiently on every pass.
Baumalight is a Canadian manufacturer of light industrial and agricultural equipment supported by a dealer network across North America, with a strong commitment to right-to-repair support and locally available parts. A key purchasing note: the cost to add the S1050 in the field is greater than ordering it mounted at the factory, as field installation requires extra freight and a completely new hose set. Any buyer ordering a new 3P38 should request the S1050 at the time of factory order — it is the most cost-effective route and ensures the hoses are correctly sized and routed from day one.
Features & Benefits
- Single-Remote Tractor Compatibility — Enables full 3P38 operation (swing and lift) on tractors with only one hydraulic remote, eliminating costly tractor upgrades or added remote circuits.
- Smoother Feathering Than Tractor Controls — The external valve provides finer, more progressive sweep control than standard tractor remote levers, giving the operator greater precision during grinding passes.
- Adjustable Arm Mounting — The control head mounts on a positionable arm that can be dialled in for optimal operator reach and comfort, reducing fatigue during long grinding sessions.
- Adjustable Hydraulic Flow Valve — Allows sweep speed to be tuned precisely to match tractor output and stump conditions, maximising grinding efficiency on every pass and preventing rotor overload.
- Ideal for High-HP Tractors with Limited Remotes — The 3P38 is designed for the 60–110 HP tractor range, where single-remote configurations are common; the S1050 unlocks the full capability of the grinder on these machines.
- Compatible with Any Transmission Type — The 3P38 works with any tractor transmission, and the S1050 extends that versatility to tractors constrained by remote count rather than HP.
- Factory Installation Strongly Recommended — Ordering with the 3P38 at the factory saves significant cost over field installation, which requires a complete new hose set and additional freight charges.
- Backed by Baumalight's North American Support Network — Supported by local dealer service, instructional and service videos, right-to-repair resources, and locally sourced replacement parts.
