8 x 3.00-4 semi-pneumatic wheel assembly suited to compatible large mower deck applications, with a smooth tread, central hub and tapered roller bearings.

  • Suited to mower deck applications: Designed for use in compatible wheel positions on large cutting decks, helping support the deck as the mower travels across lawn and turf. Commonly used on large deck mowers such as the Groundsmaster® 4100-D.
  • Smooth tread for turf use: The slick tyre profile has no aggressive tread blocks to dig heavily into the lawn, helping the wheel roll across turf with lower surface impact as the mower deck moves over the ground.
  • Semi-pneumatic cushioning: The semi-pneumatic tyre provides some compliance over grass and minor surface irregularities without relying on conventional tyre pressure, reducing the need for inflation and pressure checks.
  • Compact 8 x 3.00-4 size: The smaller wheel format is suited to deck-mounted positions where a compact support wheel is required rather than the larger front castor wheels used elsewhere on zero-turn and commercial mowers.
  • Central hub position: The hub is positioned centrally through the wheel, helping simplify replacement where the existing mower deck wheel uses the same centred mounting arrangement.
  • 102mm hub length: The hub measures 102mm including the sleeve. Compare this measurement with the available space in your existing mower deck bracket before ordering.
  • 5/8″ axle fitment: Suits a 5/8″ axle, listed as 16mm in the supplied specifications. Check the axle or mounting bolt diameter on your existing mower deck wheel to confirm fitment.
  • Tapered roller bearings: Fitted tapered roller bearings support smooth wheel rotation and help reduce rolling resistance during regular mower deck movement.

Description

The SP08-300-625 is an 8 x 3.00-4 wheel assembly suited to compatible large mower deck applications. Unlike the larger front castor wheels used for steering on zero-turn mowers, this smaller wheel is intended for a deck-mounted position where it can support the cutting deck as the mower travels across grass and uneven lawn surfaces.

The smooth tread is well suited to turf applications because it does not use aggressive tread blocks that can bite heavily into the grass. This allows the deck wheel to roll across the lawn with lower surface impact as the cutting deck follows the ground.

Its semi-pneumatic tyre construction provides some cushioning over minor surface irregularities without relying on conventional air pressure. This reduces the need for tyre inflation and pressure checks while still providing some compliance between the mower deck and the ground.

The wheel uses a central hub arrangement with a hub length of 102mm including the sleeve. It suits a 5/8″ axle, listed as 16mm in the supplied specifications, and is fitted with tapered roller bearings to support smooth rotation.

Fitment should be confirmed against the wheel currently installed on the mower. Compare the 8 x 3.00-4 size, hub length, axle diameter and central hub position, and make sure there is sufficient clearance within the mower deck mounting bracket.

The SP08-300-625 is commonly used on large deck mowers such as the Groundsmaster® 4100-D.

Product FAQs

Fitment should be checked against the wheel currently installed on your mower deck rather than relying on the mower model alone. For the SP08-300-625, compare the 8 x 3.00-4 size, 102mm hub length, 5/8″ axle fitment and central hub position with your existing wheel.

Also check the available space inside the mower deck mounting bracket so the wheel can rotate freely without binding.

Measure the existing wheel’s tyre size, overall wheel dimensions, hub length and axle diameter. You should also check whether the hub is centred or offset and measure the available width in the deck mounting bracket.

For this model, the key supplied fitment dimensions are a 102mm hub length and 5/8″ axle size.

A mower deck wheel is mounted directly to or alongside the cutting deck rather than being used as one of the mower’s main front steering castors. It helps support the deck as the mower travels across lawn and uneven ground.

This SP08-300-625 is suited to compatible large deck mower applications.

The smooth tread has no aggressive tread blocks to grip heavily into the lawn, which helps reduce surface disturbance as the deck wheel rolls across turf. The semi-pneumatic construction also provides some cushioning over minor surface irregularities without requiring conventional tyre pressure maintenance.
